Methodology and Results

2.3. Predicted Thermal Energy Requirements

Table 4 shows the predicted annual thermal requirements for space heating and space cooling (a

COP of 0.6 for the chiller thermal to thermal efficiency was used for the absorption chiller) for each house and the thermal energy required for domestic hot water needs as taken from Annex 42. The weather data used in the calculations is the TMY2 type and the calculations were conducted in TRNSYS.
