Both existing and new buildings are increasingly subject to the twin environmental pressures of climate change and atmospheric pollution. Indoor comfort and occupants’ needs have to be met using less energy. Our expertise can help understand and improve energy efficiency and the indoor environment. E4tech employs the techniques of building physics and the knowledge of people’s preferences for this purpose. We carry out consulting projects and software development for designers and operators of buildings, as well as building research institutions.

Many of our projects provide a win-win outcome, with benefits being provided to the client in the form of improved energy efficiency, including reduced emissions in the environment offering the client improved worker productivity and comfort.
