Energy Efficiency for Buildings

Transcription

1 Energy Efficiency for Buildings Klaus Dilmetz Federal Ministry of Transport, Building and Urban Affairs, Berlin-Germany Division B 14 - energy efficiency and climate-change in the building sector

2 Outline reasons for saving energy and renewable energy use EU legislation - framework EPBD legislation for EE and REN in Germany strategies to increase energy efficiency and renewable energy use prospects

3 Energy consumption - in Germany Trend of final energy consumption / share of buildings (Petajoule ) housing trade transport industry buildings (almost 40 p.c.) source: BMWi

4 European Framework: security of energy supply economic efficiency, competitiveness sustainibility, climate protection reducing demand of energy more energy efficiency and renewables saving energy reducing energy costs economic measures for more energy efficiency decreasing energy demand especially for existing buildings Kyoto Protocol/ follow-up agreement climate change, global warming, ghg emissions.

5 European obligation DIRECTIVE 2002/91/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 16 December 2002 on the energy performance of buildings (EPBD) (guidelines for all MS) more: Implementation in Germany: Energy Saving Ordinance EnEV 2007 / 2009 Requirements for new and existing buildings (e.g. refurbishments, energy certificates) EPBD - covered scopes e.g.: heating systems insulation, energetic quality of construction material hot water supply air conditioning systems ventilation energy certificates illumination renewable energies

6 EPBD minimum requirements so far as

7 EPBD Energy performance certificates have to be available

8 EPBD more intormation by EU:

9 German strategies for energy efficiency and renewable energy by legislation + promotion Law Energy Saving Act, EnEV Energy Certificates, Energy demand for space heating lower than about 50 kwh/(m²xa), Mandatory use of REN about 15 % for new buildings (EEG) Financial benefits Loans and grants for EE/REN measures (e.g. KfW-Federal Bank, additional BAFA for renewable energies) Information, transparency in the market, best practice projects German Energy-Agency (dena), promoting Energy Certificates, Best Practice Projects Research (program for research in the building sector rd. 30 Mio. from 2006 to 2009)

10 The way to the EnEV before 2002: Heat Insulation Ordinance (1...3) Heating systems Ordinance (1.3) Energy Conservation Regulations EnEV 2002 EnEV Energy certificates EnEV % less energy consumption

11 Requirements in Germany average energy demand for space heating in kwh / (m² x a)) more EE buildings e.g. 15 promoted EnEV from 2010 EnEV since Heat Ins. Ordinance Heat Ins. Ordinance Heat Ins. Ordinance

13 D R A F T Energy Certificates lead to more transparency and promote innovative solutions for the whole building since 2008 in Germany an obligation also for existing buildings (in case of selling and renting)

14 Results of promotional programmes for energy efficient construction and rehabilitation (2006 September 2009) since 2006 energy-efficient construction or refurbishment of a total of around 1,2 Mio. dwellings with a loan and grant volume of around 25 bn. ( 6 billion budget funds, total investment around 50 billion) total heating cost savings for occupants since 2006 amounts to around 1,25 billion measures funded between 2006 and today result in an annual emission reduction of almost 3.45 mio. t of CO 2 between 180,000 und 230,000 jobs were created or safeguarded annually in the small and medium-sized construction industry

15 Results decrease of energy demand through better techniques and products e.g. windows, insulation products increase of energy efficiency e.g. better heating, cooling and air-conditioning systems increasing usage of renewable energy e.g. solar heating/cooling/pv better building design, engineering by intelligent combination of technical systems and the building construction more transparency by labelling (energy certificates)

16 Prospects more investments in buildings for ecology and economy better building energy efficiency standards 30 percent less energy demand (EnEV 2009), second step further 30 percent reduction will be aimed for 2012 better education, training and best practice examples more passive houses and plus energy houses as a new standard in future new jobs in this sector
