ECOTECT is a complete building design and environmental analysis tool that covers the full range of simulation and analysis functions required to truly understand how a building design will operate and perform. It finally allows designers to work easily in 3D and apply all the tools necessary for an energy efficient and sustainable future. Check out it's features to learn more.

Early design focus

4 April 2007

In almost all projects, decisions made in the first few weeks have the greatest overall impact on building performance. Where it is on site, its basic form and orientation, internal layout, external materials, window size and position - ECOTECT helps you get all this right from the very beginning.

Built by and for designers

20 Jan 2008

ECOTECT was written and developed by architects with its application in architecture and the design process firmly in mind. However, it is also used extensively by engineers, local authorities, environmental consultants, building designers, owner-builders and environmental enthusiasts alike. To see how others are using it, check out the Gallery and Example Output pages.

Most visual and interactive
