The annual temperature distribution profile suggests that the spaces are above the comfort zone for over 5000 hours in an year and the annual cooling load is as high as 87 KWH/m2 in the south bedroom. One of the bedrooms in each flat will also require a minimum amount of heating though which is minimal at less than 10KWh/m2.
