European Framework:

security of energy

supply

economic efficiency,

competitiveness

sustainibility,

climate protection

• reducing demand

of energy

• more energy

efficiency and

renewable energy

• saving energy

• reducing energy

costs

• economic measures

for more energy

efficiency and

decreasing energy

demand especially for

existing buildings

• Kyoto Protocol/

follow-up agreement

• climate change,

global warming,

ghg emissions

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: www.buildingsplatform.org

Implementation in Germany: “Energy Saving Order – EnEV 2007”

Requirements for new and existing buildings (e.g. refurbishments, energy certificates)

EPDB - covered scopes e.g.:

heating systems

insulation, energetic

quality of construction material

hot water supply

air conditioning systems

ventilation

energy certificates

illumination

renewable energies


German strategies to increase energy

efficiency by legislation and promotion

Law

(Energy Saving Act, EnEV – Energy Certificates, Energy demand

for space heating lower than about 50 kWh/(m²xa))

Financial benefits

(promotion by 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, PR

Research

(program for research in the building sector –

rd. 30 Mio. € from 2006 to 2009)


The way to the “EnEV”

before 2002:

• Heat Insulation

Ordinance (1...3)

• Heating systems

Ordinance (1….3)

Energy Saving Order – EnEV 2002”

“EnEV 2007” - Energy certificates

“EnEV 2009” - 30 % less energy consumption


Requirements in Germany average energy demand

for space heating in kWh / (m² x a))

more EE buildings e.g.

EnEV 2009

15

50

promoted

from 2010

EnEV 2002

70

since 2002

1995 -2005

2. Heat Ins. Ordinance

150

1984 - 1995

1. Heat Ins. Ordinance

200

1977 - 1984


Improvements in the buildings sector

e.g. using EE- techniques and thermal solar systems


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)

Who is involved in Germany e.g.:

• Ministries for Buildings and Economics - regulations

• Local Administrations - enforcement, execution

• Industry – product development

• technical colleges, universities – education, research

• Handcraft - education, training, apprenticeship

Energy agencies (like dena) - promotion, best practice

• KfW, BAFA - financial benefits

• house owners, energy consumers


Prospects

• more transparency by labelling (energy certificates)

• more funding and advancement for 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 in 2012 in Germany)
