Based on a large number of researches and engineering practices both domestic and overseas, it is shown that the building parameters to be determined during scheme phase can exert a great effect on the building energy consumption. In this paper, through a combination of the popular design method of building parameterization at present and the design goal of energy saving during the scheme phase, the author carries out researches on the design methods and tool development which are applicable to parameterization of building energy saving in this stage. In connection with the characteristics of both modeling process of parameterization and energy saving design, and by means of steady calculation as well as simulation, this paper establishes an simplified model to calculate the overall energy consumption of air-conditioning, heating, lighting and equipments, and ultimately gives suggestions on design of scheme for energy saving by optimization with the genetic algorithm (GA). On the basis of the model, a software platform is developed by computer language QT and openGL interface and is oriented to the design users and sets up the MMI (human–computer interaction) software interface for parameterization of building energy saving, which achieves automatic modeling of parameterization and promotes research on practical design cases. 相似文献

ABSTRACTThe EU members have adopted regulations and official methods for evaluating the energy performance in buildings. Most of these methods are applied at the end of the project phase, with few opportunities to correct erroneous design decisions when the desired building energy performance is not achieved. It is demonstrated that there is no European standard for sustainability and that the decision-making process during the development of a building project is compromised by the methodologies and some concepts, as thermal inertia, are withdrawn. Currently, the industry has been developing alternative tools for evaluating energy performance and CO2 emissions in buildings over their entire life cycle. These software programs, which belong to the BIM environment, use databases and make simplifications adapted to the stage of design when the software can be applied. The main objective of this paper is to evaluate the accuracy of this software and how the databases and simplifications influence the decision-making process in building design. Calculation examples are carried out with various tools and compared to real building performance data. The results demonstrate that, as with the official methods, the tools influence the results and therefore condition, sometimes wrongly, the decision-making process to produce better buildings. 相似文献
