Abstract: The purpose of the present paper is to emphasize the influence of desired interior air temperature in a house on its thermal behaviour, and the corresponding cooling and heating loads. The ground floor of the house includes: a living room, a bedroom, a kitchen, a bathroom, the stairs room, all connected to a central hall. At the first floor there are two bedrooms, a bathroom, the stairs room and the main hall. Thermal gains or losses of the house partitions (walls, windows, ceilings, floors, etc.) are computed based on heat transfer laws and available norms, taking into account thermal inertia of exterior walls and accordingly the thermal transfer delay between interior and exterior of the house. The inside air temperature is set to different values inside comfort zone, in order to compare the savings or losses in required energy. The results are presented for full day simulations along the year, comparing each room’s loads with respect to its orientation. The results are useful in designing thermal units, for optimal operation, corresponding to minimum yearly heating and cooling energy consumption and maximum comfort with respect to ambient monthly conditions.

Keywords: Seasonal thermal or refrigerating loads; inside air temperature; optimal operation; minimum heating and cooling energy consumption.
