General introduction Energy efficiency in
buildings
In Europe 40 of our energy use is consumed in
buildings, more than by industry or transport.
That is a lot. It is too much. There is great
potential for energy savings in this field, often
at little cost EU commissioner Andrias Piebalgs

EuroACE strongly welcome the Green Paper and are
looking forward to the discussions and the future
action plan. Our position paper can be

Energy efficiency in New Buildings
Directive on Energy Performance in Buildings

• And where relevant, also
• Active solar systems and other heating and
  electricity systems based on renewable energy
  sources
• CHP electricity
• District or block heating cooling
• Natural Lighting

Energy calculation of new buildings shall include

• Thermal characteristics (incl. insulation,
  glazing and air tightness)
• Heating installation (incl. hot water)
• Air Conditioning
• Ventilation
• Built-in lighting
• Position orientation of building
• Passive solar systems and solar protection
• Natural Ventilation
• Indoor Climatic Conditions

Energy efficiency in New Buildings

• Directive on Energy Performance in Buildings
• Will in the new building sector increase
• the use of insulation and low e-glazing
• focus on energy efficient products like, façade
  and roof systems, glazing, windows, boilers,
  ventilation systems, air condition systems,
  lightning
• focus on thermal comfort in the building and
  thereby solar shading system, heating control
  systems, building automation, natural ventilation
  systems and daylight optimization
• use of renewable heating systems like solar
  panels for hot water, CHP systems
• Therefore EuroACE welcomed the directive.
• We are looking forward to a strong and efficient
  implementation in the member states.

Energy efficiency in Existing Buildings
Directive on Energy Performance in Buildings
The directive require that the member states
apply minimum energy efficiency standards to
existing buildings (over 1000 m²) undergoing
major renovations. EuroACE are looking forward
to the implementation in the member states. We
have the expatiation that some member states will
not implemented this in a strong and efficient
way, while others has strengthened the directive
and reduced the 1000 m² to all buildings
undergoing major renovations EuroACE are
looking forward to discuss this part of the
directive in the future, also regarding the Green
Paper and future action plans.

Energy efficiency in Existing Buildings
Large energy-saving and CO2 reduction
potential Highest in CEE countries (up to 35
energy savings) Average of 28 energy-saving
potential Reduction of final energy demand by
1.5 Reduction of emissions by 35 MtCO2 - As a
supplementary comment renovating of the existing
building stock also create local jobs

Energy efficiency in Existing Buildings

• Financial and economic (not a completed list)
• Recognise that highly cost-effective and very
  substantial energy savings can be achieved in
  almost all of the high-rise stock
• Prepare for energy market liberalisation and
  ensure that individual metering and billing
  replaces the existing infrastructure.
• Make holistic resident/stakeholder involvement
  and advice for funding support
• Facilitate and support the creation of new
  investments for instance the Energy Service
  Directive to accelerate sustainable, energy
  efficient refurbishment

Binding vs indicative targets

19
Binding vs indicative targets
Energy efficient glazing GEPVP estimate that a
reduction of at least 140 million tons of CO2
could be achieved if all glazing in EU 25 was low
e glazing
Energy efficiency measures in buildings
generally Eurima estimate that increased energy
efficiency in buildings could easily achieve the
overall 8 reduction in CO emissions that the EU
has pledged to deliver by 2010
Energy efficient shading of buildings ESSO
estimate that a reduction of at least 10 to 15
million tons of CO2 could be achieved if roller
shutters were used for the improvement of thermal
insulation in private houses in the EU.
Renewable energy for heating and cooling of
buildings ESTIF estimate that consistently
developing of this potential, this figure could
rise to 680,000 GWh by the year 2040. This amount
of energy equates to 6 of the EUs current
energy demand.

Binding vs indicative targets

• The energy saving potentials are identified by
  the industry, they
• are cost effective
• reduce the demand for fossil energy
• reduce the CO2 emissions
• Past experience shows that without an obligation
  to reach clearly set-out targets, member states
  have little incentive to adopt policy measures
  which are conducive to achieving the objectives
  set out in EU law.

Looking for the future

• A strong political and public awareness for
  energy efficiency in both new and existing
  buildings, together with economic and financial
  support to energy efficiency in the existing
  building stock, will help us to reach the
  identified savings.
