Reduction of pressure losses in HVAC installations

The project defined the concept environmentally friendly indoor climate where users’ need for a healthy and productive climate can be met with low energy consumption, equal to savings of 90% compared to the current requirements of the Danish Building Regulations. Ventilation without draught and acoustic noise problems should not trigger annual CO2 emissions of more than 1-3 kg/m2. www.miljorigtigtindeklima.dk provides specific guidelines and a calculation programme, enabling an overview of pressure loss and duct dimensions, a programme which calculates heat balance, and an overview of key figures for ABC categories for environmentally friendly indoor climate.
