Building Energy Modeling by means of BIM software. A case study with Water Flow Glazing

Abstract

Building energy modelling is an inter-disciplinary area of research which involves, among others, concepts of electrical and software engineering, mechanical engineering and also, architecture. Building energy models are used at the design stage for the purpose of energy code compliance certification. The accuracy of results depends on how well the building model has been developed and calibrated. Most of the programs available in the market take into account occupancy pattern behavior, thermal parameters of construction elements, hvac and lighting systems. However, the impact of thermal mass and the influence of active energy management systems have not been accurately reported. This paper presents a review of significant modeling methodologies which have been developed and adopted to model the energy behavior of buildings. A BIM-oriented methodology for building energy modeling will be presented. This research has included case studies to investigate the feasibility of modeling active systems, such as water flow glazing. Finally, the ability of transferring data among different software is also studied.
