Integrated Environmental Solutions has launched its VE-Ware program, which is available free to download online, and gives users limited access to its Apache thermal analysis software. New and existing buildings can now have their energy and carbon emissions easily assessed for free at

VE-Ware will help increase the energy efficiency of the world’s buildings, both domestic and commercial, by giving instant feedback on a building’s energy consumption and carbon dioxide emissions based on real geometry, and using international data on climatic conditions and the typical characteristics of different building, room and system types. It is ideal for use at early stages as it facilitates iterative design, allowing the comparison of different design, layout and system options.
