Challenges & opportunities for the
Solar Shading Industry in EU

Agenda:
• ES-SO: Who are we
• Solar Shading: Energy savings & comfort
liveability
• Building development and European
direction
• Challenges and Opportunities
2
 Who are we?
 The umbrella body of the solar shading trade
associations from different European countries
 Solar shading in Europe: 400,000 people
across the 27 States of the European Union
with annual sales of over € 15 billion

ES-SO: Who are we?




Defend, promote and support interests of our
industry
Joint effort = Catalysing energy!
Solar Shading = essential building technology for
effective e-performance
Evolving to healthy and natural comfort including
day lighting (liveability!)

1. ES-SO: Who are we?




Permanent contact between members and
authorities
Location: Brussels, ideally placed
Positive contribution in helping EU Commission
obtaining Energy Strategy
Contributory & advisory capacity

Solar Shading?
Our top three arguments on solar shading
1.
2.
3.
Reduces need for artificial cooling in summertime and therefore
saves precious electric primary energy
If intelligently automated, reduces heating needs in winter by
harvesting free, renewable solar energy
Promotes the use of free, renewable and natural daylight,
reducing the need for electricity for lighting,
 Evolving to healthy natural comfort (liveability!)
All products combined, can reduce the energy consumption
in the EU’s building stock by almost 10%, according to
ES-SO’s scientific study ESCORP-EU25

2. Solar Shading?

”The selection of solar shading
should always be one of the first
steps in the design of HVAC systems.”

”The integration of solar shading is
more and more important in the
future to optimize the investment
and operation costs.”

Some Facts…
• EU Commission determines 80% of national
laws through Directives or Regulations
• Determinant for industry, so we need to act
and lobby!
• EU 20-20-20 is certainly to improve climate,
and energy efficiency but…
• Reality = $ or € are the hard facts!

41% of total = e-consumption in buildings,
approximately 370 Billion €

E-savings from 30 to 60% in buildings achievable
10% can be saved by Shading (Escorp 25 study) =
about 37 Billion € = about 3 X annual turnover of
our total EU Solar Shading industry
With smart, integrated and combined holistic
building technologies for new build & renovation.

2020 onward all new build shall be “nearly zeroenergy”
Revolutionary change in insulation of the opaque
parts and air-tightness + heat recovery through
windows comes to mind first
Building envelope = main source of energy loss or
gain
Windows are the weak spot & not dynamic
24
Energy efficiency is mentally associated with
better insulation of buildings. Right?
25
But what about the weak spots: the
windows?

Trend to low energy housing if without dynamic
solar shading
 overheating unavoidable is fact!
Slightest energy coming in is trapped, cannot get
out because of extra insulation and airtightness!
Remember irradiation data up to +2500kWh/m²y
Easy solution air-conditioning?
First avoid the problem!

Building development and European
direction
“Now, air conditioning guzzles 15 per cent of total
American energy consumption, higher than any other
country, using the same amount of fossil fuel as the
whole of Africa employs for all its energy needs.”
‘Cold Comfort’, Rob Sharp in The Independent of Aug 3, 2010

Should be considered as first client – architect
meeting takes place.
Become part of building codes (is in many
countires)
Included certification systems like BREEAM or
LEED
