Transcript of Worldwide, 30-40 % of all primary energy is used in buildings.
Between 1985 and 1997, the average size of a European home increased from 83 sq. metres to 87 sq. metres
80 % of energy is used in small households<1000 sq.m / Europe.
Thus, there lies the largest saving potential
In France, the government has decided to refurbish all its public buildings by 2012 in order to cut the energy
consumption by almost 40% by 2020
By using well-proven energy efficiency techniques, 70 to 90 % of a building’s energy need for heating or
cooling can be cut.
Investments in improved energy efficiency in buildings could generate an additional 2 - 3.5 million green jobs
in Europe and the United States alone
In low income countries, the residential sector often represent over 90 per cent of all CO2 emissions from
buildings
Out of more than 3000 CDM projects in the pipeline as of May 2008, only 6 seek to reduce energy demand in
buildings
The building and construction typically provides 5-10 % of employment at national level and generates
5-15% of the GDP
In Germany for example, environmental technology is to grow fourfold to 16 % of industrial output by 2030
In 2030, biomass use will still represent over half of the residential energy consumption in developing
countries
