Modelling an Optimisation Selection Method for Buildings Design Toward Environmental & Economic Objectives
Improving the performance of buildings based on their energy consumption is a challenging task. The main contributing factor to the amount of energy a building consumes is associated with maintaining the satisfaction of the building’s users, by controlling the conditions within a building’s envelope. Two main design factors control the overall buildings energy performance, the Heating Ventilation and Air Conditioning (HVAC) system design and building envelope design. There are several studies aimed at finding optimum solutions, evaluating these factors individually. The researches focused on the HVAC system design, has limited number of variables going into it, comparing different systems, operation set ups and fuels. As for the researches focusing on the buildings’ envelop design, a large number of envelope’s design variables can influence the building’s energy consumption, such as its shape, geometry, material composition, elevation, and location, lead to different energy consumption rates. This research systematically investigates how three main building envelop design variables (Orientation, Aspect ratio/compactness and Window to Wall ratio) impact the overall building’s energy performance, including the potential of integrating sustainable energy generation systems, in search for optimum buildings designs than can achieve an environmental and economic balance. The first component is specific to the analyses of buildings’ energy performance/consumption, based on the three building’s envelop design variables. The energy performance considers different building geometries (from a square to a rectangular aspect ratio that is of length twice the width). Then, orienting those different forms at different directions. Further, varying the external walls composition at different window to wall ratios. The results are used to calculate the net yearly energy consumption rates and understand the patterns of energy consumption influenced by those three variables. All simulations are specific to the climate condition of ...
