Looking at optimal temperature control in buildings.
According to the Cape Town 2011 State of Energy and Energy Futures Report, industry, including the building sector, accounts for 43% of the South African annual energy consumption.
The heating and cooling of buildings contribute significantly to the demand placed on the grid. According to the International Journal of Thermal Sciences (2003), time-of-use electricity rates encourage the shifting of electrical loads to off-peak periods at night and weekends. Therefore the goal of temperature control in buildings is to ensure minimal energy consumption while still maintaining optimal comfort levels.
Temperature control in irregularly occupied buildings has traditionally made use of basic control methods, which are usually not able to solve all the challenges encountered. Recently, however, there has been increasing interest in the concept of modern control strategies for integrated building systems.
