Ritter – a new residential complex in Feldkirchen near Graz – combines innovative technology and sustainability with the highest level of living comfort and was awarded the provincial Energy Globe STYRIA AWARD 2022 in the “Application” class, category “Earth”. The HSE-team, BT-Anlagenbau's HVAC specialists, was instrumental in the successful realisation of this project. The HSE-team carried out the entire heating and sanitary installation, the cooling of the flats and the controlled ventilation of the living space.
The residential complex, built in 2021, was implemented as a net-zero building. A groundwater heat pump for heating and cooling the residential units and a solar power system form the basis of the emission-free energy supply. In addition, the technology of concrete core activation was used in combination with a smart ventilation system. Digital measuring stations for measuring the temperature, humidity and carbon dioxide content of the air enable these systems to interact optimally so that exhaust air, waste heat and excess energy can be fully utilised, thus creating an energy cycle.
