Nachhaltigkeit
„Nachhaltig
sind Systeme oder Bauweisen,
wenn sie sich – auch aus zeitlich, räumlich und
thematisch größerer Distanz – als richtig,
nützlich und hilfreich erweisen.“
Quelle Roland Gnaiger
“Systems or designs are sustainable, when
they prove to be accurate, useful and helpful also with temporally, spatially and thematically
greater distance,“

Service Package – Team
• Umweltverband Vorarlberg:
process coordinator, support in
questions of tender law
• Energy Institute:
energetic optimization
• Spektrum GmbH:
ecological optimization
Modul 1 – Preliminary Planning
• Development of specific energy efficient
and environmental criteria together with the
decision makers (and planners)
• Formulation of an « eco-program », usually
basis for a decision in a political board
All criterias have to be fullfilled by all
planers and craftsmen
• Supervision in architectural competition:
support in developing tendering documents,
validation of projects in the competition
Modul 2 – Optimization of
planning, tendering procedure
• Development of a material-, construction
and energy concept
• Basis for call for tender
• Environmental check of all call for tender
documents
• Generation of specific eco-criteria with the
database « baubook – ökologisch
ausschreiben »
• Assistance in tender law
Modul 3 – Realisation
• Craftsmen Information
• Checking of all products craftsmen are
going to use (product declaration list)
• Approval of product declaration list
Modul 4 – Control of success
• Controlling of products in use at the building
site
• Diverse measurements: blower door test,
indoor air quality, …
Energetic Optimization
Things we look for:
Planning:
• Economical calculation of energy efficient parts
of the building or the whole energy concept
• Dimensioning of parking space for bikes
Shell:
• Limitation of heating and primary demand close
to Passive House Level
• CO² equivalent max. 38 kgCO2/m²
• No active cooling, but clever planning to avoid
overheating
• Prevention of Heatbridges
• Free cooling at night
Energetic Optimization
Things we look for:
Building Services:
• Preverential use of renewable energy sources,
for example heat pump, district heating,
biomass
• Installation of a ventilation system with heat
recovery (air change rate between 0,1 and 2,5
h-1 regulated with CO² measurement)
• Installation of a PV plant
• Energy efficient lighting
Main aim:
We support municipalities by achieving their
goals. We help them to get what they wanted.

How to convince decision makers?
• Focusing on lifecycle costs and not on investment
costs (taking subsidies into consideration when
proving economic feasibilty)
• Making sustainable construction cost efficient:
define energetic/ecological standard in an early
stage
• Better air quality and less environmental impact for
only 2% extra costs due to an environmental choice
of materials
• Competition between municipalities: everyone
wants to be the best
• Making sustainable construction easier than doing
it in a conventional way
Optimized public buildings
•
•
•
•
Need 80% less energy
Grey energy can be reduced significantly
They offer more and longer value
Sustainable public buildings are centers of
discussion and make up opinions
• They are multiplicators and help to spread
knowledge about energy efficient and
ecological buildings
• 1 – 2% higher costs for ecological materials
• Energy efficiency has to be economically
proofed
Referencens
• We support municipalities in Vorarlberg by
realizing and renovating building types like
Schools
