Even in the UK over heating of buildings is quite common.
Internal loads through people e.g. large families, the increase in electrical equipment in the home (LED TV’s, computers etc.), higher solar gains due to larger glazed areas and property orientation all contribute to overheating. Another reason is the increased insulation levels, a building will generate a lot of heat in the summer, and insulated buildings will keep this heat in the building. We therefore need to be aware of increase heat in a building during the summer.
This equates to an increased number of buildings with a cooling requirement in summer..
