Abstract: The purpose of the present paper is to closely simulate thermal behaviour of a family house located in Muntenia region, Romania, throughout the year. 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 elements of the house. The rest of the heat gains are closely related to house occupancy, lightening and humidity sources, hourly simulated. The results are presented for a full day simulation over the year, comparing each room’s loads with respect to its orientation. The results are useful in house design phase, for the optimal orientation of the house, corresponding to minimum yearly heating and cooling energy consumption.

Keywords: Seasonal thermal or cooling loads; house design phase; optimal house orientation; minimum heating and cooling energy consumption.
