Envest 2 is a BRE software tool that simplifies the otherwise very complex process of designing buildings with low environmental impact and whole life costs. Envest 2 allows both environmental and financial tradeoffs to be made explicit in the design process, allowing the client to optimise the concept of best value according to their own priorities.
Designers input their building designs (height, number of storeys, window area, etc) and choices of elements (external wall, roof covering, etc). Envest 2 identifies those elements with the most influence on the building's environmental impact and whole life cost and shows the effects of selecting different materials. It also predicts the environmental and cost impact of various strategies for heating, cooling and operating a building.
