Multiobjective control architecture to estimate optimal set points for user comfort and energy saving in buildings

Abstract

Temperature control in buildings is usually driven by energy conservation although the occupants’ comfort is also important considering its impact on productivity and health. However, energy efficiency and comfort are opposing objectives and therefore this type of problem can be resolved by means of a multiobjective optimization approach. The simulations we carried out indicate that set points optimization has the potential to reduce energy consumption in the order of 10% while also providing a comfortable work environment for the occupants.
