Content of the presentation
1.High level viewpoints
2.Designing process
3.Examples of the energy solutions
High level view points
1. Energy company of the block enables building a
block-scaled energy system. The energy company
owns and administers the energy systems in the
block and is responsible for the maintenance and the
functionality of the system.
2. Tight cooperation with the city of Vaasa, Vaasan
Sähkö and Tekes enables innovative solutions – the
solutions support the development targets of all of
the parties.
3. Tight cooperation with the companies in the
energy sector from the beginning of the project
ensures development and commercialization of the
innovations.

INKA programme – Innovative Cities –
Sustainable Energy Solutions
The aim of the programme is to create internationally attractive
innovation clusters in Finland based on top-notch talent. Innovation
clusters include companies aiming for growth that are capable of
creating brand-new products and services for the international market.
Designing process
1. Designing is controlled by energy strategy and
regional BREEAM system
2. Innovative designing methods and tools (Knotworking, optimization tool and BIM-based planning
environment)
3. Designing is done in tight cooperation with the
city of Vaasa, Vaasan Sähkö and the companies
in the energy sector. All viewpoints are included in
the decision-making from the very beginning of the
project.
BREEAM Communities
• Controlling the process
and involvement
• Social and economical
well-being
• Natural resources and
energy
• Land use and ecology
• Traffic and
transportation

Strategy
Optimizing the energy solution of the block following the energy strategy:
Optimizing the lowemission energy
production solutions
Reducing the peak
power and recycling /

Building automation
§ Integrated system enables smart functions
§ Comprehensive consumption metering
§ Smart sensors installed in the structures
§ Smart control strategies:
• Presence identification, air quality sensors,
minimizing network pressures, utilization of
weather forecasts
§ The self-diagnostics of the automatization
tells where the maintenance should be focused
on
§ Data visualisation for the users
Natural ventilation of the parking hall
Energy and Cost Savings
Comparison between traditional building block,
which just fulfill the building regulations and Wasa
Station
Rough estimation of the results:
•
Additionnal investment to the energy solutions 1,8 M€
•
Yearly savings in 10 years period up to 120 000 €/a
•
Yearly savings in upkeeping costs in 20 years period up
to 0,45 €/sqm/month and in total 8,6 M€ / 20a
Interest rate 4 %, energy price escalation H 5% and E 3%, energy price H 41 €/MWh; E 95/75 €/MWh
Thank You!
