Increasing energy costs and the growing awareness of the environment necessitates us to pay more attention to heat insulation. More and more frequently houses are built with an energy efficiency of KfW 40 [KWh/m²a] or even at the standard of carbon-neutral houses KfW40plus. All these various requirements are covered by us in the CH.TROST GMBH planning process.

Registered with the Deutsche Energie-Agentur (german Energy Agency, DENA) we are authorised for both issuing energy performance as well as energy passports for residential and non-residential houses and advising both the builder and architect.
