6100 % renewable for heating and HW
How can this work?
Reducing heating energy demand
Thermal retrofitting of buildings:
- retrofitting-rate from 1%/a to 3%/a (35.000 HH/a to 100.000 HH/a)
- High quality of retrofitting (30 – 60% heating energy reduction)
Rate of new buildings: ongoing trend 1%/a,
high energy efficiency standard (Low energy or passiv house
standard)
Framework: continuing consumption trends; raising m²/capita
7100 % renewable for heating and HW
How can this work?
Increasing solar energy for hot water
private HH: increase from 4,1 PJ/a (2005) to 25 PJ/a (2030)
60% of hot water by solar
Industry: thermal solar for low-temperature use (< 250°C)
from 0,5 PJ/a (2005) to 6 PJ/a (2030)
Use of CHP at biomass-power plants
Heat pump for certain applications
(single family home in passive house standard)

State support program „Building of Tomorrow“
Support innovation of sustainable building technologies
- Focus on Energy Efficiency and Renewable Energies
Support cost reduction of sustainable technologies
Support market penetration
Project results are public available on data base

Example of a virtual

Vienna
Reduction of heating
energy demand by
80%
12Example: Energy Efficiency power plant
Barriers:
for policy it is easier to build 1 x 1.000 MW power plant
than 1000 efficiency projects x 1 MW
„producing“ is more sexy than „saving“ (opening ceremony!)
Strengths:
Energy efficiency power plants can be build everywhere in the
country
saving transmission and distribution costs (investments and
maintaining)

Passive house standard as a political dimension
Vienna: new city quarter
„Aspanggründe“
Land owner: city administration
2006: public tendering for residential
building cooperative
Passive house standard was
pre-condition of the tender!
Start construction: spring 2009
24Passive house standard as a political dimension
In Region “Vorarlberg” all new residential
buildings from “residential building
cooperatives” must fulfill passive house
standard
In Region “Niederösterreich” all public
buildings (schools, kindergarten, public
offices) must fulfill passive house standard
by 1.1.2008
25EU-policies on Energy Efficiency buildings
Das Europäische Parlament fordert
die Kommission und Mitgliedstaaten auf,
bei Energieeffizienzanforderungen an Gebäuden
das Potenzial voll auszuschöpfen
Als verbindliche Bestimmung wird vorgeschlagen,
dass alle neuen Gebäude
ab 2011 nach Normen für Passivhäuser
oder gleichwertigen Normen für Nichtwohngebäude
gebaut werden müssen.
Entschließung des Europäischen Parlaments
vom 31. Januar 2008 zu dem Thema "Aktionsplan für Energieeffizienz:

27Energy Performance Contracting (EPC)
Participants at Energy Performance Contracting
Contractor Building owner
(private company in the (e. g. municipalities,
sector energy savings) ministries, counties
28Energy Performance Contracting (EPC)
cash flow:
yearly pay-back rate
contractor
investments building owner
(private company
in the sector (e. g. municipalities,
energy savings) ministries, counties)
29Energy Performance Contracting (EPC)
Strengths: company offers best technology (cost/benefit)
company has self interests in optimising energy saving results
“all in one hand” responsibilities
pre-financing of contractor (if needed)
weaknesses: more work for contract design (EPC only for larger projects )
re-evaluating, when user behaviour changes during the contract period
