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

General introduction Energy efficiency in buildings

Green paper on Energy Efficiency

EuroACE strongly welcome the Green Paper and are looking forward to the discussions and the future action plan.

Our position paper can be downloaded at www.euroace.org

Improving energy efficiency in:

- New buildings

- Existing building stock

www.euroace.org


Slide7 l.jpg

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

Slide9 l.jpg

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

Report on energy savings in high rise buildings

Improvements to the building fabric

Wall insulation

Roof insulation

Floor insulation

Window replacement

Improvements to the heating system

Thermostatic radiator valves and balancing valves

Boiler replacements

Slide15 l.jpg

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

Slide17 l.jpg

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

www.euroace.org



Slide19 l.jpg

Energy saving in high rise buildings sector:

EuroACE estimate that energy efficient renovating of the existing building stock could reduce the energy demand with 28%.

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 EU’s current energy demand.

Slide20 l.jpg

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.

Slide21 l.jpg

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.
