Heating, cooling, electrical demand, and comfort control in buildings

Description de la recherche

Energy used in buildings for heating, cooling, and lighting causes up to 40% of the carbon emissions of developed countries. Buildings are the sector with the greatest potential and lowest cost for carbon reduction. There are many regulatory and certifications incentives to make buildings more sustainable. Quantifying used energy in buildings is a challenging problem for energy engineers and architects. The energy consumption of a building can be determined through three various methods. Although, experimental methods provide the main accepted and validated results for determining used energy in buildings, still they are very time consuming and expensive to be performed in every building. Besides, there are two substitutions for determining used energy in buildings, the first method which is called top-down approach, treats the residential sector as an energy sink and is not concerned with individual end-uses. The other approach which is called bottom-up, extrapolates the estimated energy consumption of a representative set of individual houses to regional and national levels, and consists of two distinct methodologies: statistical method and the engineering method. In our research, engineering methods will be considered specifically, and we try to achieve a reliable simulating method to determine energy consumption in buildings.
