The calculation of the energy performance and production has been made according to national standards.
Our future homes need to provide healthier, more comfortable living environments – without negatively impacting our climate. LichtAktiv Haus offers a high standard of living full of fresh air and daylight while covering its entire energy demand, including electricity, through renewable energy.
This is a particular challenge when renovating older homes as they often have much higher energy demands.
Despite its lack of a heat recovery system or central air conditioning, which are often too costly to implement in older homes, LichtAktiv Haus is able to achieve carbon-neutrality. The home’s automated roof windows make a remarkable contribution to this by providing natural ventilation. An efficient control system automatically opens and closes the windows according to the temperature, CO2 concentration and humidity in order to create a healthy indoor climate.
