... attributes and inf H the factor of opening’s position and air force exposure. Annual heating demand of the building is 33.78 kWh/m 2 whereas cooling demand is 27.34 kWh/m 2 . 3. GSHP system ... reads the annual TRNSYS heating and cooling load profile so as to determine the values of the peak heating and cooling loads for each month of the year (see Table 2) and their durations. Moreover, ... temperature estimations (average deviation ±2.5 K) when annual heating and cooling demand values are close and approximately equal to 30 kWh/m 2 and it is assumed heat pump absence. 5. Conclusion...
