House size has significantly increased over the recent decades in many countries. Larger houses often have a higher life cycle energy demand due to their increased use of materials and larger area to heat, cool and light. Yet, most energy efficiency regulations for buildings fail to adequately include requirements for addressing the energy demand associated with house size. This study quantifies the effect of house size on life cycle energy demand in order to inform future regulations.

In October 2016, the Architects’ Council of Europe (ACE) submitted a response to the public consultation of the EU Commission’s Joint Research Centre (JRC) on draft indicators for the assessment of the environmental performance of buildings.

The non-renewable (fossil) primary energy requirements for the production of insulation materials (grey energy) differ considerably. E.g. less than 100 kWh/m³ is used for the production of materials requiring little processing such as wood shavings or cellulose fibres, but 1300 kWh/m³ is needed for the manufacture of foam glass, PU (polyurethane) or XPS. When calculating the energy payback for insulating materials, the expenditure for their production is compared to the saving of primary energy resulting from their insulation effect.

The European Commission's 2014 Communication on Resource Efficiency Opportunities in the Building Sector identified the need for a common EU approach to the assessment of the environmental performance of buildings. A study to develop this approach was initiated in 2015 by DG ENV and DG GROW, with the technical support of DG JRC-IPTS.

Energy efficiency regulations for buildings often focus solely on operational and thermal energy demands. Increasing a building׳s thermal energy efficiency is most often undertaken by increasing insulation thickness and installing high performance windows. These measures can result in a significant increase in embodied energy which is currently not considered in the majority of existing building energy regulations.

Initiated by the French association for the development of low carbon buildings (Association pour le développement du Bâtiment Bas Carbone-BBCA), the BBCA label for new office buildings was launched. This voluntary label attests the exemplary nature of the building carbon footprint.
