The process presented above was applied to elaborate the test sequences for two climates: Zurich and Stockholm.

The predicted monthly values of the space heating demand are computed as follow:

The test sequences were optimised for the following reference conditions:

• a reference solar combisystem design with the following characteristics : the collector area is 12m2 and the heat storage volume is 600 litres,

• a reference building with 60 kWh/m2 heating demand in Zurich conditions (referred as SFH60).

These reference conditions come from IEA Solar Heating & Cooling programme Task 32 [6].
