Development of a support tool for building design optimization and renewable energy integration
Résumé
This paper describes a decision-support tool, SERAD, which was created with the aim to be used as an instrument to predict the heating/electrical demand of residential houses and to optimize the design parameters to improve the energy performance. Another aim of this tool is to analyze different renewable energy systems (photovoltaic/thermal solar systems, geothermal heat pumps or wood boiler heating system) and to design them in order to match the energy demands. Different aspects, like economic analysis, environmental impact and energy reduction potential are studied and used as criterions in the last stage of the tool which concerns the selection of the technology. At this point, it is possible to have multiple solutions formed by an arrangement of different systems on the same construction site, their advantages being added. Using a complex multi-criteria decision-support method, SERAD will automatically outrank the alternatives for the specific project by taking into account the weight of each criterion given by the decision maker. SERAD could be used to obtain quick parametric studies and to optimize/observe the impact of different design parameters of the building or renewable energy technologies on the energy demand/supply
