Abstract
Heating, ventilation and cooling of buildings are 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 Direc-tive (EPBD) is being implemented in building codes on a national level. Due to high energy consumption and often unacceptable indoor climate energy (noise, draught) some European countries do not recommended full air-conditionings. Alternatively, heating and cooling may be done by radiant heating and cooling systems, where pipes are embedded in the building structure (floors, cei-lings, walls) or in the centre of the concrete slab (Concrete Core Temperature Control). The present paper discuss the limitations and possibilities of radiant cool-ing systems in office buildings demonstrating the essentiality of a good and inte-grated building design to obtain an acceptable comfort level. Different office buildings with different dimensions of south windows are analyzed and their influence of internal comfort are compared.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
