Evaluierung der CO$_{2}$-Minderungsmaßnahmen im Gebäudebereich

Abstract

The goal of this study is to estimate the future CO$_{2}$-savings of the current and planned reduction measures in the context of a trend scenario. In addition it has been analysed, which additional measures are necessary in a scenario of improved building renovation, in order to reach the reduction goal of 120 million tonnes by 2010 in the residential building sector. For the calculations an average GDP growth between one to two percent has been assumed. And for the fuel oil price a long-term average growth rate of 1.5 % per year has been supposed, despite of the present high price level. According to the population forecast of the BBR an increase from 83 millions in 2005 to 84 millions by 2010 is expected. The floor space per capita continues to rise and as a consequence the total floor space grows from 3.1 to 3.4 billion square metres. At present the renovation potential is insufficiently exhausted, because the overall number of renovations is too small and the quality of the renovations does often not correspond to the requirements. For the calculations an exploitation factor of 32 % has been used. For new buildings the model calculations have used a 31 % higher consumption compared to the standardized calculation method of the energy saving ordinance (ENEV). The following list shows the spectrum of the measures which have been analysed. [...
