Like eating well and exercising, buildings can make us feel good and live well. We spend up to 90% of our time indoors; therefore, buildings should be designed for us! The MULTICOMFORT design concept is about building and renovating our homes, offi ces, schools, hospitals and other buildings in a way that gives us improved comfort, health and wellbeing whilst protecting the environment. 

MULTICOMFORT buildings incorporate the PassivHaus standard so have a very low energy demand and provide the ultimate in Thermal Comfort. In addition, MULTICOMFORT buildings provide high levels of Acoustic Comfort, creating a sound environment, enhanced Visual Comfort offering optimum levels of natural daylight and connection with the outdoors, plus improved Indoor Air Comfort, increasingly important as we become more urban and our buildings are surrounded by busy roads, on flight paths or in higher pollution areas.
