Heating and cooling systems for better energy efficiency.

Author(s) : OLESEN B. W.

Summary

Heating, ventilation and cooling of buildings is responsible for 30-40% of the energy consumption in buildings and a corresponding significant amount of CO2 emission. Since 2006, the European Energy Performance of Buildings Directive (EPBD) is being implemented in building codes on a national level. For new and existing buildings this requires a calculation of the energy performance of the building including heating, ventilation, cooling and lighting systems, based on primary energy. Each building must have an energy certificate and regular inspections of heating, cooling and ventilation systems must be performed. This has increased the focus on energy efficiency of systems and there components. The concept of the European standards developed to support the EPBD is presented in this paper. These standards may include alternative calculation methods and many European countries are using national methods. This means the heating system may be evaluated differently in different countries.
