    Abstract

    In 2006, new tighter energy performance requirements were introduced in Denmark for both new buildings and renovation, including a new classification system for low energy buildings. These demands are based on the directive on Energy Performance of Buildings, the EPBD (2002/91/EC). In general the effect of the new requirements for renovation is that existing buildings should be brought up to the energy performance level of new buildings in connection with larger renovations and other substantial changes in the buildings. To demonstrate how it could be done, a thorough energy efficient renovation of a typical Danish single-family house from the 1960/70’s with need of renovation has been initiated and the preliminary results are presented in this paper. It is worth noting that about 500,000 of a total of 1.1 million Danish detached single-family houses were erected in that time period. Specifically, the purpose of the project was to demonstrate that energy efficient renovation of a typical single-family house would lead to large reductions in energy consumption in a cost efficient manner, and at the same time improve living conditions. The focus has also been on achieving a commonly acceptable design in close cooperation with an architect. A similar renovation project was carried out on an old poorly insulated single-family house built in 1927. The project showed that large profitable energy savings are possible. The results are summarized in [Overgaard 2005] and described in detail in a report available on the internet: http://www.rwsc.dk/EP_Villa_Projektrapport_RW_DK/main_report_villa.pdf.
