Climate friendly building in Germany
Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety Dipl.-Ing. Klaus Dilmetz
Unit B I 3
Energy-efficiency, energy saving and renewable energies in the building sector
www.bmub.bund.de
Outlook
• Reasons to increase the use of renewable energy and
saving energy in buildings by federal regulations
• European framework - EPBD
• Development of regulations in Germany
• Requirements
• IKI - examples
• New standards, best practices

Energy consumption in Germany per sector
space heating
illumination
domestic hot water
other processing energy AC cooling
mecanical energy
electronic data processing
other process cooling energy
DE Energy Concept from 28. September 2010
– Buildings account for about 40 % of final energy consumption in Germany and about a third of CO2 emissions.
– „…the building stock’s energy performance is the central key to modernising our energy supply and achieving our climate protection targets. “
www.bmub.bund.de
DE Energy Concept from 28. September 2010
– By 2020 we want to reduce heating requirement by 20 %.
– by 2050 we aim to reduce primary energy demand by an order of magnitude of 80 % (compared with 2008).
– „…instruments (EnEV, EEWärmeG) must be updated to achieve renovation targets, to the extent that this is economically feasible…“
– create incentives, not order compulsory renovation.
– German government will set a good example reduce energy consumption in its future new and existing buildings.

• reducing demand
of energy
• saving energy
• more energy
efficiency and

sustainability,
climate protection
• Kyoto Protocol/
follow-up agreement
• climate change,
global warming,

……….
economic efficiency,
competitiveness
• reducing energy

European obligation “EPBD”
(DIRECTIVE 2010/31/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL
of 19 May 2010 on the energy performance of buildings - recast) – (guidelines for all
MS) more: www.buildup.eu
Implementation in Germany: “Energy Saving Order” (EnEV)
Requirements for new and existing buildings (e.g. refurbishments, energy certificates)
EPDB - covered scopes e.g.:
insulation, energetic
quality of building envelope heating systems
hot water supply ventilation air conditioning systems
illumination renewable energies
e.g. solar – technique
energy certificates

EPBD
Article 2
Definitions
For the purpose of this Directive, the following definitions shall apply:
…
2. ‘nearly zero-energy building’ means a building that has a very high
energy performance, …The nearly zero or very low amount of
energy required should be covered to a very significant extent by
energy from renewable sources, including energy from renewable
sources produced on-site or nearby;
www.bmvbs.de
EPBD
Article 9
Nearly zero-energy buildings
1. Member States shall ensure that:
(a) by 31 December 2020, all new buildings are nearly zero- energy
buildings; and
(b) after 31 December 2018, new buildings occupied and owned by public
authorities are nearly zero-energy buildings.
Member States shall draw up national plans for increasing the number
of nearly zero-energy buildings. These national plans may include
targets differentiated according to the category of building.

German strategies to increase renewables and
energy efficiency e.g.:
Law
Energy Saving Order (EnEV) – Energy Certificates, requirements
for buildings
Financial benefits
promotion by e.g. KfW-Federal Bank – additional BAFA for
renewable energies
Information, transparency in the market, best practice projects
promoting Energy Certificates, PR
Research
program for research in the building sector – ca. 9 Mio. €/a

Measures
• Further development of regulations – e.g. Energy
Saving Law (EnEG), Energy Saving Ordinance
(EnEV)
• Improvement of Norms and Standards on German,
European and ISO Level (e.g. DIN V 18599)
• Promotion of energy-efficient buildings (e.g. new
standards (e.g. Plus Energy House)
• Information and support e.g.:

German Realisation of the EPBD: DIN V 18599
www.bmvbs.de
• many options for energy
efficient engineering and
integrate solar systems
New Buildings
www.bmvbs.de
• Use of high potentials in the
existing buildings stock for more
energy-efficiency and renewable
energies (e.g. Thermal and PV-
Solar Systems)
Existing Buildings
www.bmvbs.de
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)
Development in Germany

Example for
possible
technique to
realise a plus
energy house
Plus Energy House
www.bmvbs.de
• better building energy efficiency standards (25 percent less energy demand from 2016 (EnEV 2014), important step forward
on the way to the 2020 energy standard with economic technical requirements) • more transparency by labelling (energy certificates, energy classes and customers
information)
• more advancement for investments in buildings for ecology and economy (KfW-promotional programs) • nearly zero-energy buildings by 31 December 2020 - with a very low energy
demand and renewable energies use
