Internal air temperature diversions in summer period in the case of a residential building.

In recent years around Europe several investigations, measurements were carried out in order to reduce the buildings energy need, but the energy need for cooling, still shows a growing curve. In relation to residential buildings different standards has distinct requirements for internal/operative temperature. To assure the required air temperature and comfort different types of air conditioning systems are installed in buildings. Therefore, in many countries especially in summer period the power networks are strongly overloaded. The internal air temperature in a residential building through two different summer periods was measured. In the first period the internal air temperature was measured without residential ventilation and air conditioning system. In the next summer period measurements were accomplished with residential ventilation and air conditioning system. The indoor air temperature variation was calculated using the EN ISO 13790 standard's methodology, values obtained from the measurements were compared with the analytical values. The theoretical values were used in the case of summer, hot and torrid days for heavy construction buildings. Certainly, the indoor air temperature variation and the energy need for cooling was analysed for one residential building. [ABSTRACT FROM AUTHOR]
