100 % 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

100 % 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) 8

Example: Program Building of Tomorrow
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 Website: www.hausderzukunft.at

Example: Energy Efficiency power plant
Virtual energy efficiency power plant EU-project EffCoBuild: Database on http://www.oegut.at/en/themen/erweit ertes-europa/effcobuild.php

Example: Energy efficiency power plant Example of a virtual energy efficiency power plant in Vienna Reduction of heating energy demand by 80%
12
Example: 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) 13
