Sundeep GwaSh: Every project is unique
because every client is different. I believe
it is paramount that the client receives
a building that not only meets their requirements in an efficient and cost effective design but also emulates the values
of the company. We at our practice consider Sustainability as an intrinsic part of
design. So we were more than enthusiastic for this project since MEDA, having

conservation in the State of Maharashtra;
made its intentions very clear by floating
their Office Building and Campus architectural design competition based on
green building principals. Therefore this
building has been designed with a strong
environmental agenda so that MEDA
have an exemplar building of sustainable
design which will give them a stronger
identity and advertise their commitment
to environmental design. We have designed MEDA campus, referring to the
GRIHA guidelines to ensure effective and
holistic environmental design. The principles of GRIHA have informed many of the
design decisions. The design aims to gain
a five star GRIHA rating.
Ecoconstruction india: What kind of water
saving measures has been used in this
project? What kind of savings are we
expecting?
Sundeep GwaSh: I think we should perceive
sustainability as a very basic concept. If we
are thinking about water as a resource, we
need to Reduce the consumption, Reduce
the wastage wherever possible to start
with. And that implies such design sensibilities while the project is on tracing papers! For instance we were happy when

their commitment to environmental design. The building program required the
design to provide for the Office, Auditorium, Exhibition Pavilion and Guest House.
The application of BIM software was
integral to the design development of this
building because it allowed the architects
to perform accurate tests on design iterations to arrive at an optimal and effective
environmental design. Thus the architects
can confirm, with empirical analysis, that
their design surpasses theory and will perform in practice.
we could consolidate the toilet rooms at
one place for the whole office building
while planning the layouts. Then low-flow
fixtures on all water dispensers will minimize the water demand from the building.
The total water savings compared with
standard fixtures is calculated at around
60%. This will not only provide financial
savings but will also reduce the demand
on the municipal water supply.
The landscape has been designed to
have a high proportion of xeriscaping
which will reduce the water requirement. The other parts of the landscape
will be watered through a drip irrigation system which is highly efficient and
will ensure minimal water wastage. All
plants and trees will be native to Pune
and as a result are expected to use 66%
less water than exotic species.
THE APPLICATION OF BIM
SOFTWARE WAS INTEGR AL TO
THE DESIGN DEVELOPMENT
OF THIS BUILDING BECAUSE IT
ALLOWED THE ARCHITECTS TO
PERFORM ACCURATE TESTS ON
DESIGN ITERATIONS TO ARRIVE
AT AN OPTIMAL AND EFFECTIVE
ENVIRONMENTAL DESIGN
The second effort goes for Recycle on
project wherever possible. The building
will recycle 100% of the waste water it
produces, with an STP plant. The plant will
provide water for landscape, flushing and
natural cooling systems. Combined with
the rainwater harvesting, 100% of all nonpotable water requirement will come from
recycled sources. The building will reduce
the demand on the municipal water supply
by harvesting the rain which it receives. The
rainwater harvesting system is designed to
capture all roof run-off rainwater which is
stored in a tank for later use. The hydrologic report revealed that there are two bore
wells on site. The design has integrated
with this site feature. All non-roof run-off
will be collected by the Bore wells below
the site and will contribute to the municipal
water supply. The excess of water from the

the salient features of the design.
Design Goals Objectives
• Provide MEDA with a superlative building of sustainability developed from initial design to operation that will promote
and advertise the values of the agency
• Increase worker productivity and morale
• Holistic and efficient environmental design to reduce impact on environment
and overhead costs
• High GRIHA rating and ECBE Compliance
storage tank will also supplement the deep
Bore wells, thus 100% of the water is either
recycled into the building or contributes to
the ground water table.
Ecoconstruction india: Can you please let
know the kind of concepts being used for
energy efficiency?
Sundeep GwaSh: The similar concepts are
applied to the conservation of energy. Reduce the consumption wherever possible.
Reduce the wastage. Use the renewable
resource like solar energy. At the onset of
concept stage, the design thrust was focused on the right orientation. Building
mass was orientated on North-South axis
as a response to the site dimensions. The
core is placed on the West side to minimize
the Western solar gain and glare in the office space. The atrium affords light into the

Design Concepts
Key Environmental Design Concepts:
• Harvest Rainwater
• Minimize Solar Gains
• Harness Solar Energy
• Use Low Humidity Potential (evaporative cooling)
Office
Design Concepts
• Efficient utilization of daylight provides
natural lighting to all work spaces
• Open office arrangement does not obstruct natural light. It also stimulates
employee interaction
• High proportion of workstations have
direct views to exterior or interior
landscaping
deeper parts of the plan. Each office floor
plate has a long facade facing North and
South to gain maximum daylight. The facades have also been treated accordingly
to their orientation to the sun.
The South and North facades have
been designed to allow maximum light
penetration because the solar gains are
low. A multifunctional light shelf has been
designed to shade the window from the
high sun in the summer and also to reflect
this light and illuminate the interior. The
East and West facades are dominated by
double walls to prevent solar gains heating
the interior, only a few slit windows allow
North light to penetrate to the interior.
Using a BIM model the design team
conducted analysis of the designs to ensure that the regularly occupied spaces
had maximum day-lighting. The evolved
design achieved 90% of office floor area
as naturally lit. The design intentionally
planned only a part basement reducing
energy spends on mechanical ventilation
and lighting systems. The most critical and
right decision which the design can boast
of, is the decision to not go with conventional HVAC system. Instead, the design
incorporated the non-refrigerant comfort
cooling, encouraging to utilize the concepts of direct and indirect evaporative
cooling and radiant cooling.
Then there are other inclusions in design like efficient lighting systems, utilization of solar power, specifications for energy efficient envelope.
number of them arrayed on the sculpted
tree branches in an artistic manner.
tive Cooling provides cool air to the office
spaces which has been cooled via a misting
shaft. Hot western air draw in to shaft. Water that has pre-cooled in the water tower
is sprayed down the shaft to cool the air
to 26° as it drops down the shaft. The air
is directed to vertical risers which transport
it to the A.H.U rooms on each floor. The air
is distributed throughout the office via ducts
and nozzles directed at working stations.
The radiant cooling system works in synergy
with the PDEC system. It converts the heat
radiated from lights, computers, solar gain
and the human body more effectively than
an air cooled system. The reason for its effectiveness is because the form of the heat
is the same. As a result the PDEC system has
a smaller thermal load and thus performs
more efficiently. The hydronic slabs will have
naturally cooled water running through
them which brings down the radiant temperature of the slab. The pipes are evenly
spread throughout the floor plate to ensure
an even temperature throughout the office
increasing the thermal comfort for employees. The thermal mass of the concrete slab
retains low temperatures from the night and
radiates them through the day further reducing the reliance on mechanical cooling. The
stack effect in the atrium helps to exhaust
the hot air through louvers at the top on the
eastern side. The preceding environmental
design has ensured that the building requires
minimal power and utilizes passive means of
environmental control without compromising on the thermal comfort of the building
users. The analysis data shows that each
space in the building maintains a comfortable and steady 26 °C throughout the year.
The system will be operational from 09:00 to
18:00 to provide comfortable temperature
for office hours 09:00 - 17:00. This is in line
with our commitment to client that the Office will stand out as an exemplar building
sustainability from design to operation.” 

Ecoconstruction india: What kind of benefits
does native plants bring; instead of exotic
varieties?
Sundeep GwaSh: It is important to have native
species of plants and trees because they increase biodiversity and vibrancy in the ecosystem. Not only does nature benefit from
this but it also increases the aesthetics of the
landscape. Another advantage of using the
native species is that these would be low on
maintenance, water requirement and costly
chemicals; which is not the case with exotic
species and manicured lawns. The landscape
has also been designed to have a high proportion of xeriscaping which will further reduce the water requirement. The other parts
of the landscape will be watered through a
drip irrigation system which is highly efficient
and will ensure minimal water wastage. All
plants and trees will be native to Pune and as
a result will use 66% less water than exotic
species.
Ecoconstruction india: How does natural
cooling help inhabitants? What kind
of natural cooling concepts have been
proposed in this design?
Sundeep GwaSh: The human comfort is conventionally assumed to be provided in terms
of only temperature, but the factors like
fresh air and humidity are ignored. The users would get better comfort conditions
and indoor air quality in the natural cooling
systems compared to conventional HVAC
systems. In this case, the design utilizes the
concepts of direct and indirect evaporative
cooling, thermal mass, stack effect and radiant cooling.
The synergy of these systems provides
large savings over a standard water cooled
HVAC system but does not compromise on
thermal comfort. Indirect Direct Evapora-
Plan
• The plan is very efficiently designed space.
The programming of the space has been
considerate to the different user groups
and levels of privacy.
• The departments are necessarily bifurcated to distinguished them but share a
linear core and circulation route so as to
maintain inter-departmental connections.
Ecological Landscaping
Design Concepts
• Abundance of green landscaping provides
attractive and inviting spaces for employees and guests to relax and socialize
• Podium landscape orientated to receive
the cooling westerly winds
• Seating design to be sociopetal so that
employees interact and socialize, increasing worker morale
• A central water feature provides an aesthetic focal point whilst also creating a
cooled micro-climate in the shade of the
solar tree
• The landscape is designed with only native species of plants and trees to be considerate to the environment.
• A central solar tree provides renewable
energy whilst also affording shade to the
landscape seats.
• Green link unifies the atrium living wall
with the exterior landscape inviting employees and guests to the podium landscape. The designers have focused on creating visuals to green space from all areas
of the building
Facade Treatment
Solar Design
• The facades have been treated accordingly to their orientation to the sun.
• The analysis shows that in the summer
months the roof, East and West facades
receive the most solar gain and thus have
been designed accordingly.
• The analysis shows that in the winter the
South receives large amounts of radiation
due to the low sun. The design will utilize
this to increase the thermal comfort in the
winter
Light Shelves (South Facade)
The South and North facades have been designed to allow maximum light penetration
because the solar gains are low. A multifunctional light shelf has been designed to shade
the window from the high sun in the summer and also to reflect this light and illuminate the interior
Slit Windows and Double Wall (East/West)
The East and West facades are dominated by
shading walls to prevent solar gains heating
the interior, only a few slit windows allow
North light to penetrate to the interior
GRIHA Design
The architects have designed MEDA with
an environmental agenda as a top priority,
referring to the GRIHA guidelines to ensure
effective and holistic environmental design.
The principles of GRIHA have informed many
of the design decisions and therefore the
subsequent section of the report will communicate the project referring to the GRIHA

Empowering India’s Today and Tomorrow
MR. VINEET MITTAL, VICE CHAIRMAN WELSPUN RENEWABLES
The country is now on its way to successfully implement massive solar energy projects
for overall sustainable development. Consequently India is now fast emerging as an
attractive destination for investments.
T
he Indian government has favourably prioritised renewable energy
industry, keeping in view India’s
generation potential. The Honourable
Prime Minister’s vision has set the capacity
target for 175 GW of renewable energy by
2022. Mr. PiyushGoel, Honourable Minister of State I/C for Power, Coal and New
& Renewable Energy made a significant
statement at Ministry of New & Renewable Energy’s RE-INVEST 2015 “Renewable
Energy is no longer a supplementary or
secondary form of energy - but a primary
energy source for India.” Intentions like
these from the government have set the
ball rolling for numerous initiatives. Of the
overall renewable vision, bulk capacity of
100 GW has been allocated to solar energy projects, while wind accounts for 60
GW.
Among one of the key visions for a
new India, the Prime Minister is focusing
on making the cities efficient, scalable
and sustainable. A 100 smart city program
has been launched with 22 states already
working on a blueprint for its successful
execution. 45 cities with one to four million people have already been identified
which will be upgraded to smart cities.
Additionally 8 selected cities with have a
satellite smart city attached to them. By
2019 it is estimated the fi rst three smart
cities will be delivered.
One of the components of these cities
is a smart grid. These grids are capable of
effi ciently managing electricity consumption of industrial units as well as consumer
home appliances. Consequent to this,
wasteful energy consumption and power
outages are reduced; thereby resulting in
lower utility bills and energy access without any interruptions.
Rooftop solar is a budding business
stream in India. The installed capacity has

SUSTAINABLE
been rising steadily over the last few years.
However, the industry needs more support
to grow at the same rate as the groundmounted segment. It has been estimated
that with conducive environment India’s
rooftop solar capacity could touch 1.5 GW
in 2018, as compared to the current 285
MW.
Rooftop systems are sustainable and
much more cost effective in the longer
run. Given conventional fuel sourcing
challenges and rising energy demand, solar can give a strategic push to combat
India’s energy deficit. Installing rooftop
project accompanied by smart metering
solutions can help the cities in accessing
clean energy while helping the grid manage energy flow efficiently. While industrial units and organisations are realizing
that solar based captive power generation
is more sustainable. Energy generated
from these systems will help lower their
diesel and grid-connected consumption,
thereby reducing operating expenses.
Some of the other overall benefits of
rooftop projects are:
• Photovoltaic roof-top installations at
the tail-end of the grid can enhance
grid-stability and reduce losses
• Savings in land requirement and costs
• Savings in development of new transmission infrastructure
• Creation of value from under-utilized /
unutilized rooftops
• Good choice for distributed power generation system
With the present regime’s focus on
solar rooftop and the much anticipated
net metering policy, the segment is sure
to pickup. MNRE has already mandated
that new thermal power stations have
to install rooftop systems. Anticipating
that funding is a critical component, the
Ministry is already in talks with KfW for
offering loans for off-grid installations.
These developments spell a positive
turn for the industry. However, there are
certain key challenges that simultaneously need attention.
• There isn’t enough rooftop space to
set up a feasible solar system. The
area quantum has to be contiguous
and large enough to make it financially feasible.
• Most old structures have installed AC
systems and pipe network on their
rooftops. This leaves barely enough
space to set up power systems.
• Additionally most of the old building
weren’t designed keeping to take the
extra weight of a typical rooftop project. If as a policy was mandated that
new structures are designed keeping
a rooftop system in mind, this issue
could be effectively addressed
• Even though a rooftop might be feasible, the whole question of rooftop
rights is a big question mark if the
building owner were to sell-off his
property at a future date.
• Especially in residential complexes,
owners are still wary of setting up a
project. As it could involve remodelling their rooftops to a certain degree.
Awareness and promotional campaigns could help address this issue.
• Net metering policy once incorporated will be a big inducement for building owners to adopt solar rooftop
projects 
Global Green Summit; A Vision
with Action can Change the World
The Advisory Board Meet of the Global Green Summit took place on May 15, 2015 at
the Taj Palace, Chanakyapuri, Delhi to create a conference agenda that is holistic and has
the potential to influence a green revolution in the country.
T
he Global Green Summit was incepted in the year 2010 with an objective to promote and discuss the
strategic agendas for a sustainable future
by uniting architects, developers, green
practitioners, urban planners, policy makers and infl uencers.The Advisory Board
Meet targeted to evolve a high impact

“People across the Indian social spectrum are aware of the concept of sustainable development and the time has come
that we organize ourselves, the way we
live and especially the way we devise our
future” said Ar. Ashok Lall.The roundtable
began with the key message about and
motivating a green culture to build a sustainable future for India.
Some of the key topics discussed at
the meet were affordable and sustainable
housing, role of facilities management in
motivating a sustainable culture,smart
cities, waste to energy, green citizenship,
priorities of building, economic viability
and regulationsetc.I think GGS can do a
great deal of work in thrusting the Green
Movement forward. A movement like this
becomes a connecting point for all the
stakeholders and brings them on one platform,” says KoushikSarkar, CEO, USG Boral - Exclusive Green Partner of The Global
Green Summit 2015.
‘Make in India’ emerged as a theme,
focusing on creating employment, promoting higher quality of manufacturing
in the country,innovation and working towards boosting the agrarian economy.The
board also broached upon an important
discussion on whether India was ready
to deal with the environmental impact
with rampant production.Robert Hoellrigl,
Head- R&D, ENCRAFT India Pvt. Ltd, who
extends his wholehearted support to GGS,
states“Environmental awareness and energy efficiency is on top of our agenda. For
this reason, the tie-up with the Global
Green Summit is a great match.”
What followed was an intellectual discussion on renewable energy i.e. priority
financing in solar, importance of energy
axis and grid compatibility. Welspun Renewables joins hands with GGS to bring
out about effective solutions. “By steadily
building country’s largest solar capacities,
we are proving that green energy is doable and can be made affordable through
rapid expansion. It is here that the objectives of GGS and Welspun Renewables are
aligned,” states Vineet Mittal, Vice Chairman, Welspun Renewables.
While discussing India’s Smart City
Mission, Mr.Sanjay Prakash remarked,
“Smart cities are made by smart people”
The advisory board agreed on the fact that
we cannot outsource ‘smart’ to technology. The economic engine of the city, liveability and citizen participation are some
of the aspects that need to be considered
along with physical infrastructure.
To summarise the extensive efforts taken by the board in bringing crucial insights
on the table, Teddy D’Souza,Operations
Head (India & South Asia) of Knauf AMF
India Pvt Ltd, points out, “If such minds
from the industry come together with
their vast experiences, I’m sure that we
can work together to recommend ideas
and prompt formulation of policies to ensure that the smart cities remain sustainable over the years.”
The Global Green Summit will be held
on October 31, 2015 at NSC Grounds,
Goregaon, Mumbai. Mr.Prabhpreet Shah,
Executive Director, creative group, said
“Being in the Architecture & Engineering
industry, we are constantly faced with the
challenge of improving the Sustainability
quotient of the urban environment while
addressing aspects like aesthetics, user experience, functionality, economic viability
and constructability. For a consultant incharge of envisioning and delivering such
new facilities, GGS is an ideal platform.”
The summit will allow the participants
an opportunity to reach out to prospective
stakeholders and share a vision for sustainable India. The Global Green Summit
looks forward to collaborating with individuals and organizations who share our
vision for a sustainable future.Commenting on the upcoming conference, Mihir
Thakkar,Head-Global Green Summit ,said
“Apart from addressing industry issues of
importance, GGS 2015 will also provide
networking and business opportunities
to firms that have chosen the green path.
In order to make ‘green’ available to the
masses, we need to make it economically
viable.” 
Mihir Thakkar, Head, Global Green
Summit defines the purpose of
the Summit and the consequent
sustainable impact that has pervaded
in the Industry
Besides the-year-round communications, the extensive media coverage
enables us to take the voice of industry to a larger audience and keep
them engaged in the ‘green movement’ initiatives.
ECOCONSTRUCTION INDIA: What is the
objective of The Global Green
Summit?
MIHIR THAKKAR: The Global Green
Summit started in the year 2010 as
a forum to spread awareness about
green building materials and technologies. Over the years, we have realized there are many platforms and
organizations that share our goal of
sustainable development. But our interaction with the industry leaders i.e.
architects, urban planners, builders,
engineers, building material providers etc. made us realize that India has
the potential as well as skill and technologies to build smartly with minimum impact on the environment.
Recognizing this need to bridge the
gap between the stakeholders has
helped GGS evolve accordingly.
ECOCONSTRUCTION INDIA: How is The
Global Green Summit different
from other platforms?
MIHIR THAKKAR: We believe in action
and accountability. The conference
is designed to unite the best minds
from the industry and encourage active audience participation. We have
created a format that entails detailed
panel discussions with a diverse panel
that is well-received by the industry.
ECOCONSTRUCTION INDIA: How does
the Global Green Summit lead
to positive action in the ‘green
space’?
MIHIR THAKKAR: Sustainability is a journey, not a destination. One can only
strive to be more sustainable in their
personal and professional space and
hope to influence change – rapidly,
profoundly, and sustainably. On a
macro level, I think we have a government that is extremely proactive
and this summit is trying to facilitate
a dialogue between the industry and
the policy makers. At last year’s summit, Shri. Prakash Javadekar, Hon’ble
Union Minister of Environment, Forests and Climate Change invited all
delegates to share their views and
suggestions with him. His presence
was a huge boost to the industry.
ECOCONSTRUCTION INDIA: What should
the industry expect from The
Global Green Summit 2015?
MIHIR THAKKAR: This year the conference will be held in Mumbai. The
advisory board meet, which recently
concluded, has laid the foundation
for a power-packed agenda. Apart
from addressing crucial industry issues, GGS also provides networking
and business opportunities to firms
that have adopted‘sustainable’ practices. In order to make ‘green’ available to the masses, we need to make
it economically viable. Incorporating
audience and industry participation,
The Global Green Summit 2015 will
redefine the conventional concept of

SUSTAINABLE BUILDING MATERIALS
Striving towards Green Window Installations
ROBERT HOELLRIGL, PRESIDENT- RESEARCH DEVELOPMENT & DESIGN, ENCRAFT INDIA PVT LTD
The energy loss through windows and doors in apartments or flats can range from 30%
to 45%. It is highly unlikely that energy costs will come down in the future hence the need
to reduce avoidable energy losses through fenestration.
W
indows and doors are becoming of major importance in so
called energy efficient buildings, ‘Green’ buildings and ‘Zero’ carbon
homes. The energy loss through windows
and doors in apartments or flats can range
from 30% to 45% which can be reduced
significantly by specifying frames with enhanced thermal performance.
Contrary to common beliefs, the frame
material, albeit being the smaller part,
plays an important role in the whole window and door U-value assessment and
can compensate in conjunction with warm
edge spacer technology for a less onerous
glazing specification.
Architects are fully aware of options
and are being able to optimise building
envelopes by means of calculation and
simulation, striving towards the ‘Green’
goal but all modern technology will not be
able to influence or predict the quality of
the workmanship of the window and door
installation.
Installation is the last linkage in the sophisticated uPVC frame supply chain; this
service is of vital importance and normally
subjected to severe price scrutiny and time
pressure. We need to ask ourselves, what
is the point in installing thermally efficient
‘Green’ window frames into carefully designed and well specified ‘Green’ building
apertures without allowing for the extra
time and extra care required to achieve a
‘Green’ installation?
UPVC installations do not differ from
wood or metal frames. The installation
principles are the same; any frame MUST
be fitted ‘plumb, level and square’ regardless of the aperture shape. The prescribed
fixing centres, evolved over six decades,but
the fasteners and sealants have improved
drastically.
Nowadays frame installation methods
are well covered in comprehensive guide62

lines and standards like the German GKF
Montagehandbuch or the British Standard BS 8213-4. India’s window industry
can benefit from the wealth of experience
gained in other countries and could utilise
today’s innovative materials which have
been developed to ensure quality and consistency on site.
For example:
Probably the most commonly used
frame fixing method in India is the rawlplug type. The rawlplug principle (detail 1)
invented in 1911, served the fenestration
industry well for decades but the Fischer
FFSZ type anchor (detail 2) has taken the
window industry by storm because of its
simplicity, effectiveness and efficiency.
Drilling 6 mm holes through steel reinforced uPVC outer frames is much easier
than 8 or 10 mm, in addition, the method
does not rely on permanent frame packers
or frame supports and their actual removal
helps to fill the gap continuously between
frame and aperture with gaskets, insulation foam and/or sealants.
The small headed anchor can be positioned anywhere within frame rebates
whilst the anchor method allows for outer
frame adjustment it has also eliminated
one of the most contentious and probably
most annoying complaints, the missing
screw cover cap!
100 years later, the visible anchor head
has now become a fenestration feature!
As conciliation, India is not alone with irregular window and door apertures. Even
countries with official national standards,
covering window apertures in terms of size,
parallelism, squareness etc. have still got issues with their regulated check reveals (detail 4). NOTE: Check reveal means that the
outer skin of a wall construction overhangs
part of the outer frame thereby sheltering
the joint between frame and aperture from
the elements like UV rays, rain and wind.
Unfortunately, India’s most commonly
applied straight through aperture construction detail (detail 3) makes it more
difficult to hide irregularities and will requiremore attention when finishing-off.
The use of insulation foam (like McCoy’s
Soudafoam gun) will be an essential part for
the installation of thermal efficient frames in
order to eliminate any energy loss through
joints, simultaneously improving the sound
proofing of the installation. Applying finishing trims to frame installations will help to
extend the lifetime of Silicone sealants. Experience has shown that the external Silicone
exposed to the elements may need replacing at least once during the service life of
the frame. Note: Regardless of geographical
location and exposure, any external sealant
failure or break down will impose unnecessary risks tothe building fabric.
UPVC frame installations, albeit being
seen, as a necessary evil, play a vital part
in fenestration and their importance will
be more appreciated with the demand for
increased thermal performance.
It is highly unlikely that energy costs will
come down in the future hence the need
to reduce avoidable energy losses through
fenestration 
Case study on Wood Wool
Acoustic Panels from Knauf AMF
GLOBAL GREEN SUMMIT 2015
A modern building interiors requires balancing multiple objectives such as
aesthetics,acoustics, environmental factors, fire safety and integration with the building’s
infrastructure. Modern innovations now address all these concerns and offer a plethora
of options in terms of visual effects, support systems and safety features.
K
nauf AMF Deckensysteme GmbH,
global manufacturer of ceiling solutions, delivering specialist acoustic, fire resistant and cost-effective ceiling
systems offering an array of products in
terms of material, tile size, ceiling grid system, face pattern and performance levels
has came up with a case study on its business unit, Heradesign’s Wood Wool Acoustic Panels.
Case Study
It is a new experience for the students of
Leiden University College in Hague, Netherlands. They no longer only study in the
newly opened, 72 metre high AvB Tower
but also live there in luxury, in nearly 400
apartments on the upper floors of the tower. On the floors below entrance hall, corridors, study areas and the Grand Café have
been combined to create an open-plan
study landscape. Acoustically, this proved
to be a big challenge for the architects from
Studio RTM.
There was the danger that talking and
other noise would combine to become an
unbearable disturbance. The wood wool
acoustic panels’ fine from Heradesign
scored with the architects not only for their
good sound absorption values, but also for
their design, size flexibility and ease of handling. Dutch architects RTM design concept
underlines the exclusivity of the course of
studies. In the entrance hall, nearly all surfaces are white, so the indirect sunlight produces a light and inviting atmosphere. The
acoustic insulation panels from Heradesign
mounted on the ceiling create an interesting grey tone with their rough surface,
which is a lively contrast.At the same time;
the acoustic panels are complemented by a
second high performance design element,
which has been used throughout – namely
the toffee-colored bamboo. It is present as
a covering for the lockers, on the floors of
the study rooms and on both the floor and
ceiling of the large auditorium.
The architects not only wanted to create an exclusive and modern ambience,
but also to capture the three pillars of the
university: peace, sustainability and international law.The diverse requirements of
the acoustic insulation panels“The search
for suitable acoustic insulation panels was
difficult, because they had to have a whole
series of attributes”, EwoudNetten, interior
designer at RTM explains.
“On the one hand, we wanted a texture
in which the nature of the material was still
visible, so that the ceiling produced a natural
ambience. On the other hand, the material
had to be solid enough for quotes to be cut
into it. At the same time, they had to muffle
the acoustics in the rooms, meet the fire regulations and be available in a suitable size.
With all these stipulations we were left with
little choice. We finally found the model fine
from Heradesign, a one-layer, 25 millimeter
thick, and magnesite bonded wood wool
acoustic panel, with a fiber width of two millimeters and a nearly crude surface structure.
The project made it necessary to use unu-
sually large acoustic panels. “We therefore
manufactured exclusive modules of 2580
x 625 millimeters, which corresponded exactly with the dimensions of the building,
for this project”, Mischa Straver, Specification Manager at Heradesign Netherlands,
explains. “The wood wool acoustic panels
were mounted on the ceiling on a wooden
grid supporting system. That was a further
advantage for the interior designers. With
no visible hangers, a monolithic impression
of a one-piece material was attained.” Before installation, the quotes from famous
philosophers were to be applied to the material. The question was whether the ceiling
panels would bear up to the cutting. The
designers were able to cut letters up to sixty
centimeters high into the ceiling panels and
thus manifest institute’s intention of bringing
a further layer of information into the building. Dutch architects RTM design concept
underlines the exclusivity of the course of
studies. In the entrance hall, nearly all surfaces are white, so the indirect sunlight produces a light and inviting atmosphere. The
acoustic insulation panels from Heradesign

LEED spans 833 million square feet
of Green Building Space in India
“USGBC believes that India is positioning itself well to become a leader in the sustainability
field in the same way that it has established itself as a global leader in technology”.
T
he U.S. Green Building Council (USGBC) has announced that Leadership in Energy & Environmental Design (LEED) comprises 833 million square
feet of green building space in India. The
announcement was made at a recent
summit hosted byThe Energy Resource
Center’s (TERI) where USGBC’s President &
Founding Chair Rick Fedrizzi and its COO,
Mahesh Ramanujam, spoke.
The summit was centered on how
businesses will lead India’s energy, water
and food security. Because LEED-certified
buildings are part of the solution for en-
ergy savings, carbon mitigation and water
conservation, LEED featured throughout
the program, including a speech from USGBC’s Fedrizzi.
“The solutions we need from our built
environment require the full participation of
the business community if we are to make
EcoConstruction India meets up with Mr. Mahesh
Ramanujam, Chief Operating Officer, U.S. Green Building
Council/ President, Green Building Certification Institute
EcoConstruction India: What role does
businesses have to play in climate
change?
Mahesh RaManujaM: Businesses have an incredibly important role to play in climate
change mitigation and adaptation. As
business and commercial activity are primary drivers of energy usage and greenhouse gas emissions, a commitment to
strong sustainability policies from key
business stakeholders can have huge implications across economies and societies.
Businesses are also able to drive innovation
and pioneer scalable new technologies
and solutions, particularly around the built
environment and green building.
EcoConstruction India: How are Indian
companies responding to this?
Mahesh RaManujaM: Many Indian companies working in a vast number of industries
are making a positive difference to mitigate and adapt to climate change. India is
becoming a leader in the production and
manufacturing of renewable energy technologies, and many infl uential business
leaders in India are strongly committed to
64
SPRING15
developing smarter business models as a
means of improving their environmental
impact.
In terms of the built environment, there
are a number of companies that are looking to the LEED green building rating system as a means of dramatically reducing
their water and energy use, as well as the
broader carbon footprint of their business
practices and saving money. ITC Limited is
one example of a company that has made
a remarkable commitment to sustainability and to LEED: 10 of their luxury hotels
across the South Asian subcontinent have
achieved LEED Platinum, the highest tier
of LEED certification available.
Infosys has been another key advocate
for LEED in India as well as in their operations around the world.
EcoConstruction India: How will you
define a smart city?
Mahesh RaManujaM: India’s 100 Smart Cities program has the potential to be very
transformative for the country, as well
as a potent example for the rest of the
world to model. We know that India citecoconstruction india
GREEN BUILDING
progress against climate change, drive energy efficiency and the development of a
diverse portfolio of energy resources that
includes renewables, conserve precious
water, and improve human health ,” said
Fedrizzi. “LEED buildings have proven to be
a big part of that solution, especially in a
country like India where energy efficiency is
so critical and the human health impacts of
rapid growth are significant.”
Environmentally Sustainable and Smart
Cities was another prominent theme at
the summit where USGBC’s Ramanujam
said, “There is not enough agreement or
acceptance that prevails on how to have
a standardized approach to plan, implement, manage and measure a smart city.
The idea of a smart city is challenging to
defi ne. However, it is our charge for USGBC, TERI, and our partners to provide
ies are growing very rapidly and that the
country is poised to add 404 million city
dwellers by 2050.This represents the largest net urban migration for any region in
the world, and failing to plan for a population change of this magnitude would
be catastrophic. Given this context, the
government’s plan of creating 100 new,
high-tech and environmentally sustainable urban corridors to accommodate India’s projected urban growth looks to be
an innovative solution for a very complex
set of problems.
USGBC’s global mission is to establish
green buildings for all within a generation,
and so we see a Smart City as a built environment that is designed to the highest
sustainable standards. Green buildings of
course play an integral role in that process.
But Smart Cities also extend beyond buildings. For example, the design of the city
and public transportation infrastructure
needs to enable people to move around
freely and easily without unnecessarily
burning fossil fuels.
LEED and other green building rating
systems such as GRIHA, are helping cities
become smarter by transforming the way
we thinking about how buildings are designed, constructed and maintained across
the globe. Work to promote smarter, micro- energy grids with programs like PEER,
are also leading the way. Cities that decentralize their power generation and adopt
more forward-looking practices along
these lines will be more resilient and they
will have cheaper, more reliable and more
sustainable sources of energy.
Additionally, a Smart City is a healthy
city for all people. Since its development
15 years ago, LEED has been a rating system deeply rooted in human health. Every
credit in the LEED rating system has a direct or indirect impact on human health.
Our latest version of LEED places an even
greater emphasis on human health and
the occupant experience in a LEED-certified building.
Another tool to help cities become
even healthier cities is the WELL Building
Standard, a performance-based system for
measuring, certifying and monitoring features of the built environment that impact
human health and well-being through air,
water, nourishment, light, fitness, comfort
and mind. WELL and LEED certifications
go hand in hand. While LEED addresses
these factors, WELL delves further to provide a closer examination of the occupant
experience.
Recently, four Indian organizations
committed to certifying their buildings
to the WELL standard: Vrindavan Chandrodaya Mandir, an ISKCON temple, Tata
Housing, the Paharpur Business Centre
(PBC) and Group 10 Technologies.
EcoConstruction India: What kind
of work is USGBC, TERI [and other
partners] doing in the field of smart city
guidance plan?
Mahesh RaManujaM: USGBC and TERI are
working very hard to help India reach its
sustainability goals through a number of
ongoing initiatives. One of the key areas
of emphasis for LEED in India is for existing
buildings that can be implemented in the
‘Smart Cities’ that are currently occupied
urban areas. We have worked with TERI
on developing new technical guidance to
advance LEED for existing buildings in India. We believe this will be responsive to
India’s unique environmental, social and
economic realties, which is an essential dimension of making sure that it is effective
for the Indian market. That’s a huge and
highly impactful area of focus.
LEED’s collaborative relationship with
TERI and their GRIHA green rating system
helps LEED continue on its path of becoming a global, regional and local mark
of quality in the sustainability field and
maintaining its leadership position in the
green buildings industry more broadly.
We hope that the synthesis of these efforts helps inform the approach that India

standardized approach, which we are intensely working on.” He added, “We believe that the five pillars for smart cities include energy, water, transportation, waste
and livability/human experience.”
According to USGBC’s recently released
LEED in Motion: India report, nine out of
10 industry senior executives in India anticipate LEED-related work to increase between now and 2019. Indian companies
are using LEED to save energy, water and
other precious resources.
“Companies such as Infosys, Tata and
the Delhi Metro are active and engaged
LEED users that are seeing a real impact
from LEED,” said USGBC’s Ramanujam.
“The advancement of LEED in India is the
result of several factors, including key strategic partnerships we have crafted with
The Energy and Resources Institute and
the Indian Green Building Council.”
“The success of LEED in India could not
be possible without the hard work of hundreds of LEED professionals working daily
to accelerate the widespread adoption of
LEED,” added Ramanujam. “This advancement is expected to continue.”
A recent survey found that 87 percent
of green building professionals across the
country believe the number of LEED projects in India will expand rapidly in the immediate future 

Mahesh RaManujaM: This is a very exciting
time for LEED in India, and we anticipate
2015 being a major growth year for the Indian green building market. In December,

transportation and human experience.
The plaque is updated whenever new
data enters the system, and displays a live

EcoConstruction India tries to
learn more about prefabrication
technology from Mr. Samir Sharan,
CEO, ACME Cleantech Solutions
EcoConstruction India: What is
Prefabrication Technology and what is
its USP?
SAMIR SHARAN: Prefabrication or prefab
technology is the practice of designing
and fabricating components or modules
of a structure at a factory and then transporting them to the site in knocked down
condition for installation. Some commonly
used prefab materials include steel frames
as structures and wallry systems, made of
wood, cement, gypsum and PUF panels.
Being ready-to-use material, it can conveniently meet the housing sector demand
and enable mass customization. Prefabricated technology therefore offers multiple
advantages over conventional construction in terms of savings on cost, time and
labour, apart from consistent quality. Prefab can also successfully address requirements of people in need of short-term
shelter and those wanting to change locations because prefab structures can be relocated conveniently without huge costs.

OF CONVENTIONAL BUILDINGS”
prefabricated parts) can help India deliver
ten million affordable homes by 2025.
As the infrastructure and housing sectors confront stiff targets from the NDA
Government, prefab technology could
help ease some of this burden via its USP of
quick assembly. For a nation of 1.25 billion
where millions are still without their own
homes, prefab could be a boon indeed.
EcoConstruction India: What has
been the response of India Inc to this
technology?
SAMIR SHARAN: The technology is still emerging in India although some large projects are
underway in a few metro cities. Offices, hospitals and other commercial buildings have
been using prefab wall and ceiling panels as
well as plasterboards and flooring systems to
create their interiors for many years.
As awareness about the benefits of this
technology spreads, end users are realizing that the overall project cycle and operational costs are much less than in the
case of conventional buildings. This has
increased demand in recent years, with
economies of scale in turn helping prices
drop. This trend will continue in the coming years and eventually boost adoption of
prefab technology.
EcoConstruction India: Is there any kind
of incentives/encouragement that the
Indian government is providing for use
of Prefabrication Technology?
SAMIR SHARAN: We firmly believe that incentives and a policy push from the Government and local bodies will help boost
adoption of the technology. The infrastructure and housing sectors could benefit
through the effective use of this technology, which is a faster and greener solution
compared to conventional buildings. The
prefab industry could receive an immense
impetus since governments in Delhi and
other states have proposed building night
shelters using this technology 
EcoConstruction India: How will the
Indian infrastructure sector benefit
from Prefabrication Technology?
SAMIR SHARAN: The growth of prefab can
be attributed to infrastructure development and specifi cations-led demand from
customers in manufacturing, process industries, poultry, dairy, pharmaceuticals,
healthcare, textile and many others.

EnErgEtica india: How exactly can one
define a smart city?
Anil KAdAm: The most effective definition
of a smart city is a community that is efficient, liveable and sustainable- and all
these elements go hand-in-hand. A ‘Smart
City’ is an urban area that is highly rated
in terms of overall infrastructure, sustainable real estate, communication Technology and market viability. It is a city where
information technology is the fundamental framework and the basis for providing
necessary services to residents. Traditionally, the water, gas, electricity, transportation, emergency response, buildings,
Hospitals and public services systems of a
city are separate and operate in silos independent of each other. A truly efficient
city requires not only that the performance
of each system is optimized, but also that
these systems are managed in an integrated way to better prioritize
Investment and maximize value. A
smart city covers all the bases ranging
from Smart Power to Smart Transport.
EnErgEtica india: What is the need for
smart cities in India?
Anil KAdAm: Cities are 50% of the world’s
population, 75% of its energy consumption and 80% of its carbon emissions and cities are growing. Today, cities face
huge challenges like congestion, pollution,
blackouts, crime, debt and rising costs. At
this pace, India will need new Infrastructure development which shall come as the
smart cities. In the time to come we will
need cities to become smarter: more efficient, sustainable and liveable.
EnErgEtica india: What kind of role do you
envision renewable energy playing in
India’s plan for smart cities?
SMART CITIES
Commenting on the development, Mr.
Anil Chaudhry, Country President and Managing Director, Schneider Electric India said
“Schneider Electric will bring its expertise and
experience to projects in sectors of Smart Cities, Urban Mobility and Renewable Energy
and is willing to explore and cooperate to deliver many such projects jointly. We are glad
to tie-up with Essel Group which will further
bolster Prime Minister Narendra Modi’s vision
to develop a 100 efficient liveable sustainable
and inclusive smart cities.” Schneider Electric
is proud of the immense competitive advantage it enjoys because of its integrated Smart
City solutions covering the complete domain
from Smart Energy, Smart Mobility, Smart
Water, Smart Public Services and Smart Data
Centres. With rich global references and collaborative knowledge transfer Schneider Electric India stands poised to serve Smart City
customers and help the country in delivering
smart, efficient, liveable and inclusive cities 
Anil KAdAm: The smart city initiatives being
undertaken by the government are likely
to entail significant investments in installing renewable energy capacity. Immense
scope exists for renewable energy given the
impetus being laid upon smart infrastructure and energy efficiency in India. As the
head of this business division for Schneider
Electric in India, it is my responsibility to
capitalise on this and ensure good growth
for the company. We have the right products and solutions and it is our endeavour
to establish superiority of our products
versus others in the market so that our
solutions are the preferred option for all.
EnErgEtica india: What kind of challenges/
opportunities do you perceive for
businesses in India to develop smart
cities?
Anil KAdAm: In less than 40 years, 70% of
the world’s population will reside in our
cities. This rapid migration will push both
current and future urban centres to their
seams and expand industrial and residential infrastructures beyond their breaking
points. This eye-opening fact raises important questions that must be considered by
cities around the world. Can this growth
be done in a sustainable way? Will cities be able to reduce their environmental
impact and carbon emissions? Will we be
able to meet the sustainability challenges
brought on by regulation and the impact
of this massive growth? And, will we expand in ways which ensure communities
are enjoyable places to live and promote
social equality?
We can answer affirmatively to these
concerns, and re-design our cities with
these thoughts in mind. With the movement towards smart cities, the urban centres we live in can become more efficient,
liveable, and sustainable in both the short
and long term, thanks to involvement
from city, citizens, and businesses. Every
city can become smarter. Smart cities start
with smart systems, working for the benefit of both residents and the environment.
Electric grids, gas distribution systems, water distribution systems, public and private
transportation systems, commercial buildings, hospitals, homes — these form the
backbone of a city’s efficiency, liveability,
and sustainability. It is the improvement
and integration of these critical city sys-
tems — done in a step-by-step manner —
that become the cornerstones to making a
smart city a reality.

ENERGY EFFICIENCY
Energy Efficient VVVF Hydraulic Lift Drive
PARAG MEHTA, RESEARCH AND DEVELOPMENT-BLAIN HYDRAULICS GMBH, GERMANY
While new energy efficient products are hitting the market every day, energy efficiency
norms and guidelines laid down by the government work as catalyst in filtering out
outdated and in-efficient products which do not meet the new energy efficiency standards
Elevator industry is no different. It has in the past few years seen energy efficient and
environmental friendly designs. VVVF technology in traction and hydraulic elevator
industry has been for a quite a while and has gradually become popular. But the
questions “When is an elevator called energy efficient?” is still by and large debatable.
Energy efficiency today is
among the most important
parameters which designers,
manufacturers and consumers look at while deciding for
a product. Product marketing emphasises on the environmental footprint and eco-friendly aspecs
in order to make the advertisement more
appealing thus attracting customer attention.
However behind the sophisticated product
marketing campaigns and green labels some
basic simple questions which interest the enduser still remain partially unanswered.
While energy consumption and money
are the only parameters in focus most of
the times, we should not forget that there
are other important parameters which are
totally discarded. To ascertain if an elevator is energy efficient, a complete life cycle
analysis (LCA) of the system needs to be
performed using proper tools and statistical information. As shown in Figure 1 a
LCA takes into consideration the complete
life span on the product from its birth till
end of life and disposal. Would an elevator system be energy efficient if it needs
less power to operate but its manufactur-
When is an Elevator Energy
Efficient?
The answer to this simple question is being debated for quite a time. Some of the
different opinions are as follows:a. If the payback period of the elevator is
3-5 years.
b. If the elevator consumes less than 3-5%
of the total energy consumption of the
building.
c. If the elevator has low operational and
stand-by energy consumption.

ing process is an environmental disaster,
takes extra ordinary resources to transport
and install, is not safe and has high maintenance costs and environmental impact?
After all the energy invested in all these
factors have to be accounted for and not
just low operation and stand by costs.
How are energy efficient elevators
classified?
Annually approximately 300,000-350,000
elevators are installed out of which 80,000
to 100,000 could be hydraulic. The world
lift stock is approximated at around 9
million installations out of which 3.5-3.8
million could be hydraulic.While archi-
Figure2: Elevator energy classification as per VDI4707
ENERGY EFFICIENCY
tects and engineers are concentrating on
making modern elevators more energy
efficient, the number of old installation
should not be ignored. Bringing the power
consumption by 25% would approximately result in 4-5 Terawatt hours of power
an equivalent which 3500 wind turbines
could generate.
New energy efficiency norms for the
elevator industry like the ISO25745 Part
1 and VDI 4707 are being aggressively
adopted in developed countries to make
the elevator system energy efficient. These
are not only applicable to the new installation but would also be applicable for
existing installation in the time to come.
For example the VDI4707 energy efficiency
norm classifies an elevator into classes. A
system would be awarded an energy class
depending on the power consumption it
has during travel and stand-by. Furthermore the energy efficiency is also based
on type of elevator system being classified.
This kind of certification is broadly based
on power and stand-by consumption and
does not consider the complete life cycle
analysis of the system.
General Market Trend
In the elevator industry 4 principal parameters broadly define market trend,business
policies of big companies, government
policies in the form of norms and regulations, customer needs and technical issues.
A classic example is the VVVF technology
being increasingly used in the elevator industry as it is being marketed as energy
efficient, environmentally friendly technology offering smoother start and accurate starting and stopping accuracy. This
technology is being widely supported by
government institutes in developed countries in the form of new energy efficient
Figure3: Elevator markettrend
norms, certifications and energy efficiency
classification of elevators. However it is important to once again underline the fact
that not every VVVF solutions available
in the market can be taken as an energy
efficient product as lower operating and
stand-by energy consumption numbers
could be misguiding especially when the
product comes attached with strings like
high maintenance costs, complicated design and exclusive service contracts only
benefitting the manufacturer and not the
consumer really. It is very important to look
at the complete picture before coming to
a conclusion rather than just concentrating
on a part of it.
Indian Hydraulic Lift Market
The unique advantages which hydraulic elevator offers in the low rise lift market are
well known. This can be seen in the E4 report published in March 2010. According
to the report from a total lift stock of 4.8
million lifts in Europe 1.18 million (25%)
are hydraulic. This means from an annual installation of 110,000-120,000 lifts,
25,000-30,000 are hydraulic installations.
The UK lift market also projects a similar
picture with around 21% of the installation being hydraulic. By estimation around
30,000 hydraulic lifts would have to be
modernised to meet the energy efficiency
norms in the next 5-10 years in UK alone.
India on the other hand is a developing
market when it comes to hydraulic installation. Not long ago were hydraulic elevators considered a problem due to some
myths in the elevator industry. Industrial
hydraulic components were used to make
hydraulic elevator power-packs; wrong design and absence of technical know-how
pertaining to the hydraulic elevators were
mainly responsible for the problems and
failures in the earlier days. However with
the availability of right components and
technical know-how the hydraulic elevator
industry has seen phenomenal increase in
number of installations in the last 8 years.
It is growing at the rate of more than 60%
p.a. The total hydraulic lift installation (including passenger & non passenger) could
be 8% of the total lifts installed annually.
Indian would have an estimated
20,000-25,000 new hydraulic installation
in the coming 5 years. This is a conservative estimate only accounting for the met-
ros and tier 1& 2 cities. More than 20,000
car parking systems would be needed in
tier1 & 2 cities to ease parking congestion
in the next few years.
As hydraulic elevators create further inroads into the Indian market the idea of
using energy efficient products is not optional anymore, rather it is on the list of
“must have” features.
Is a VVVF Hydraulic Solution
better than a Conventional
Hydraulic Solution?
Answer to the above question should be
logical as well as analytical. In order to
decide which hydraulic solution (Mechanical control, Electronic servo control, VVVF
control) is best suited for a particular application the following should be kept into
consideration:1. A mechanical hy draulic control system
offers simple, most reliable and cost effective solution. However it is not very
suitable when temperature and load
variations are very high. As the variations in oil temperature changes the oil
viscosity, mechanical valve adjustments
may fail to give the required travel
quality when temperature and load
variations are extreme. Secondly most
mechanical valves use normal solenoid
valves which are typically on/off valves.
In absence of closed loop system (realtime feedback) the valves deliver preadjusted flow without knowing the real
need of the system.
Mechanical valve solution is a good option for low usage lifts (less than 150 travels a
day) where temperature and load variations
are not extreme and simple, reliable and cost
effective solution is of prime importance.
2. Electronic servo control solution offers by virtue of close loop (real time
feedback) electronic control is the distinct advantage over mechanical valve
solution. It has proportional solenoids
which are controlled by an electronic
card which reacts to the real time signals from the flow, temperature and
sometimes pressure sensors. Thus the
system can dynamically vary the performance to suit the requirement, compensating for the wide temperature
and pressure variations.
Electronic valve solution is a good option for both moderate as well as high
SPRING15
75
ENERGY EFFICIENCY
usage lifts (more than 160 travels a day)
where temperature and load variations are
high and travel comfort, starting and stopping accuracy is of primary concern e.g.
hospitals, shopping complex, commercial
building etc.
3. VVVF control can be seen as hybrid solution combining the advantages of mechanical and electronic valves. Available
as close or open loop, the system not
only compensates very well for changes
in temperature and pressure but also
makes the control valve more or less
adjustment free. It is an energy efficient
solution which can be also applied effectively especially where high starting
current (required by motor) is not available. The power drawn by the inverter
in the starting phase is much lower than
a conventional installation and total energy savings over30% can be achieved
against non VVVF installation.
VVVF hydraulic solution is ideal in any
of the following conditions:
a. the number of cycles per day is higher
than 160.
b. The change in oil temperature and load
is very high.
c. High starting current is not available.
d. Riding comfort, starting and stopping
accuracy is important independent of
temperature and load changes.
e. Operational and standby energy savings is of primary concern.
What is an ideal Hydraulic VVVF
solution?
Figure 4 shows the six important criteria
which should be kept in mind while selecting a VVVF solution. Apart from energy
efficiency (low operating and stand-by
power consumption) other parameters
like simplicity, safety, cost effectiveness;
Figure 4
76
SPRING15
Different VVVF Hydraulic solutions
available
There are many types of VVVF hydraulic
solutions available in the market. From
simple to most complicated & cost effective to very expensive. Broadly a system is
classified into open loop or close loop depending on the technique used to control
the drive.
An open loop inverter control like the
one for e.g. using the Blain EV4 [1] offers
practical advantages as the system remains
simple, user friendly, cost effective and
easily maintainable. As seen in figure 6the
control valve does not have any interface
with the inverter or any electronic card and
is simply connected to the lift controller.
The inverter is connected to the lift controller, temperature sensor and motor and
it does not need an expensive pressure and
flow sensor. It can with the help of the embedded software calculate the load, read
the current temperature from the temperature sensor and process oil and pump
performance data to obtain motor speeds
(reference frequencies) in Hz for the full,
levelling, inspection and secondary full
speeds. Additionally, temperature control
gain and leakage reference frequencies for
Figure5: Close loop inverter system
Figure6 : Open loopinvertersystem
Figure 5 shows a close loop inverter solution. Over here the electronic card and
inverteris updated with real time data from
encoder (attached on the motor), flow,
pressure& temperature sensors. The controller thentakes corrective action depending on the variation it registers against predefined parameters programmed in the
system. Such a system is not only complicated, but also very expensive & difficult to
maintain. Secondly a close loop system can
also trigger vibrations at lower frequencies
as the system tries to constantly correct
the travel which is not required. Renovating an existing old system means not only
changing the complete control valve and
drive but also motor and sometimes pump
with costlier components making it too
complicated and expensive. In terms of
energy-efficiency and initial investment,
application of such systems can only be
justified for very high-usage lifts (over 700
cycles/day).
empty and loaded car pressures are also
calculated.As a result, less amount of energy is consumed during up travel, which
increases the efficiency of the system and
also reduces oil heating. Using the inverter
also reduces motor starting current and
the size of the electric energy meter. The
inverter is programmed to run either in
constant speed mode where the output is
maintained independent of the load and
temperature variations or energy savings
mode where the inverter reduces the full
speed with increase in load thus consuming less power but keeping the acceleration and deceleration angles during the
travel in a comfortable zone. It can take
corrective action by capturing the motor
torque at fixed intervals and re-calculating
the correct output by comparing it with
the taught parameters.
The installation of such a system is very
easy as the control valve is very much simplified by having no controls in the up direc-
reliability and low service costs should also
be given equal weightage. One should not
forget that the servicing and maintenance
cost in elevators far out-runs the investment and energy savings during the complete life span of the system. Off-course in
order to correctly tag a system as energy
efficient, a LCA should be the primary indicator and not just operating and stand-by
power consumption.
ENERGY EFFICIENCY
Stand-by energy consumption of the inverter used in a VVVF system.
Depends on the inverter size for e.g.
4 KW-17 W; 15 KW-41 W

damage to its system.

Average load the inverter can take.

tion. After giving the oil type and elevator
data a teaching run with empty car is sufficient enough for the inverter to self-learn
and configure itself fully automatically during the initial installation. Secondly such a
design makes it possible to renovate an
existing installation by just swapping few
components in the Blain control valve and
adding an inverter, making it a VVVF drive.
The solution is intentionally designed to be
backward compatible making it the most
cost effective renovation option for old installations. The down control is intentionally kept mechanical as hydraulic elevators
descend due to gravity and inverter control
is not required for 80% of the installation.
In some inverter solutions, the energy
generated by the system (conversion of potential energy into kinetic energy in down
travel) is burned into a resistor, which prevents hydraulic oil getting heated. Some
have regenerative system which tends to
convert the potential energy stored in the
oil into electrical energy which is then fed
into the grid. Such solutions look appealing in marketing brochures and theory;
however the cost of implementing (payback time more than 30 years), complexity,
practical use, availability of infrastructure
and the real benefits far outrun the appeal
and necessity.
Energy Savings
Lift consultants and architects are always
confronted with important question like
payback time and energy savings from
the end users. While the number of cycles
the elevator makes in a day is an impor-
tant deciding factor on energy savings, it is
equally important to know the following:
Figure7 Show the energy savings with
respect to number of cycles per day and
payback duration. Over here a clear comparison can be made between different situations like high inverter stand-by
power consumption to number of cycles
per day and the estimated payback period
for such an installation. As shown when an
inverter with a stand-by energy consumption of 26W running in energy savings
mode results in 44% energy savingswith a
payback period of 3 years.
Conclusion
Energy efficient Green Lift Concept
Energy performance of lifts is only one of
many parameters for Green Lift evaluation; a complete Life Cycle Assessment is
the right method for ascertaining if the elevator is really energy efficient and green.
“New generation VVVF hydraulic system”
Should not only have the advantageous
characteristics of conventional hydraulic
elevator but also be in a position to compensate load and oil temperature variations and should have minimum stand-by
power consumption.
The system software should offer different operating modes like constant speed
mode, energy saving mode etc. so that
users can select an appropriate method of
operation to suit their needs 

THE AREAS OF WASTE AND
RECYCLING, ANOTHER CENTRAL
THEME AT IFAT EURASIA IS
PRODUCTS, PROCESSES AND

Strong Environmental Markets
in the Countries targeted by IFAT
Eurasia
Furthermore, in Central Asian countries
like Kazakhstan and Kyrgyzstanas well as
in states of MENA–all of them are target
markets of IFAT Eurasia–the demand for
innovative technology solutions for the
water, sewage and recycling sector is high.
Such as in Kazakhstan: In the middle of the
Eurasian land mass the aim is to modernize
waste management. According to GTAI, in
January 2014 the government of this, the
largest land-locked country on Earth, approved a program that involves injecting
around 576 million euros into the sector
by the year 2020. They are planning to
introduce waste separation, step-by-step,
renew their fleet of waste-collection vehicles and build new waste-processing plant.
As well as solutions for the areas of
waste and recycling, another central
theme at IFAT Eurasia is products, processes and services for the water and wastewater sector. In this sector the European
Union is supporting a wide spectrum of
activities in third countries via an external
aid program. Among the countries set to
benefit from the funding between 2014
and 2020 are Egypt, the Yemen, Palestine
and Uzbekistan, but also some of the target markets of IFAT Eurasia.
