Lower energy consumption of a building due to later start of thermal comfort support

When designing district heating serving different buildings, an architectural engineer should suggest optimal operation policy for support of thermal comfort (TC) in heated buildings, based on minimizing costs for used energy and for investment in building heaters, and minimizing global environmental pollution. In this paper, by using HTB2 software, we report results of heating simulations of small Serbian residential building. Heating supported TC in the building each day during 16 hours. It was found out that if we start to maintain TC later in the morning, the energy consumption in the building may be lower and the building may require smaller heaters.
