BRE UK ClimateLite solutions

"Be at the forefront of low carbon building design"

The BRE are developing their ClimateLite tool for sustainable design. ClimateLite will help building designers to apply from a very early stage - a systematic approach that quickly and cost effectively addresses challenging current and future carbon emission targets and the use of renewable energy technologies. This three-year, DTI funded project aims to have a prototype tool ready by October 2008. Read more...

Also look at SBEM (Simplified Building Energy Model). SBEM is a computer program that provides an analysis of a building's energy consumption. SBEM calculates monthly energy use and carbon dioxide emissions of a building given a description of the building geometry, construction, use and HVAC and lighting equipment. http://www.bre.co.uk/energyrating/page.jsp?id=694
