Categories of indoor environmental quality and building energy demand for heating and cooling

摘要: Maintaining suitable indoor climate conditions is a need for the occupants’ well being, while requiring very strictly thermal comfort and high levels of air quality in buildings represents also expense energy, with its consequence terms environmental impact cost. In fact, it known that (IEQ), considering both aspects, has primary not only on perceived human comfort, but building energy consumption. This issue clearly expressed by European Energy Performance Buildings Directive 2002/92/EC, together most recent 2010/31/EU, which underlines expression judgment about consumption should be always joint corresponding level required occupants. To this aim, concept environment categories been introduced EN 15251 standard. These range from I to III, where category refers highest requirement. challenge reducing conditioning buildings, essential IEQ requirements are relaxed order widen variations temperature ranges ventilation flow rates. paper, means simulation, heating cooling demand calculated mechanically controlled office different required, ranging III 15251. The located cities (Moscow, Torino Athens), characterized significantly wheatear conditions. mutual relation between highlighted. simulations performed typical room adopted as reference validation tests Standard 15265 validate calculation procedures use space cooling.
