4 Seite 4 Ref. 411 Dr. Dagmar Everding Points-Programme Renewable Energy NRW targets Management by EnergieAgentur.NRW Monitoring starting 2006 and evaluating the progres, e. g. using indicators First Report 2010, Final Report 2020 Actually: collecting measures for realization, research project for an evaluation and monitoring concept

5 Seite 5 Ref. 411 Dr. Dagmar Everding Targets for the industrial sector of Renewables Turnover increase to 15 Billion Euro Increase of persons employed to 40,000 Pers. (Pers.employed in NRW: 7.6 million) Recruitment of companies, research institutes and international institutions Consulting and training for small and medium companies and for cities administration

6 Seite 6 Ref. 411 Dr. Dagmar Everding Targets for heating by renewables Heating supply by renewables: minimum cover ratio 20 % in new buildings in reconstructed buildings In public buildings combined with cogeneration units for heat and power

7 Seite 7 Ref. 411 Dr. Dagmar Everding Biomass Targets Biomass Srategy NRW (Ministery of environmental affairs and agriculture) Increasing the production of heat and electricity using biomass e. g. by the following measures: Innovative cogeneration plants for heat and power using biomass Development of bioenergy villages (self-sufficient) Support of new biofuel plants in NRW

8 Seite 8 Ref. 411 Dr. Dagmar Everding Research Targets Support of technology development: Energy efficiency, cost reduction, energy grids, energy storages and batteries, hydrogen technologies (e. g. using clearing sludge) (Energy Research concept NRW, Ministry of research and innovation)

9 Seite 9 Ref. 411 Dr. Dagmar Everding Solar Energy Housing Estates Example: New Building Project, Aachen Size: 43 units, 2 office buildings

10 Seite 10 Ref. 411 Dr. Dagmar Everding Solar Energy Housing Estates Example: New Building Project, Aachen Passive Houses with solar thermal collectors Measured heat demand: 10.6 kWh/m²a, Total: kWh/a Less than energy demand for domestic hot water! Comparison to heat demand of a conventional house: kWh/a (Passive house: -85%)

11 Seite 11 Ref. 411 Dr. Dagmar Everding Solar Energy Housing Estates Example: New Building Project, Aachen 3 litres-houses with solar collectors

12 Seite 12 Ref. 411 Dr. Dagmar Everding Solar Energy Housing Estates Example: Renovation-Project, Köln-Riehl view before renovation Housing Association: Erbbauverein Köln eG Year of building: Size: before renovation: 112 apartments after renovation: 133 apartments

13 Seite 13 Ref. 411 Dr. Dagmar Everding Solar Energy Housing Estates Example: Renovation-Project, Köln-Riehl view before renovation - Renovation period: summer 2001 – autumn Heat demand reduction from 160 kWh/m²a down to 48 kWh/m²a (-70%) - Domestic hot water: 55% via solar thermal collectors (280 m²) view after renovation
