Building energy modeling at district scale through BIM based automatic model generation - Towards building envelope optimization

Abstract

When a new construction is added in a dense area, the existing district may have a significant influence on the new building energy performance, and vice-versa. These interactions are almost never taken into account in the modeling tools used for building design. This paper presents a numerical platform, design within the ANR MERUBBI project, able to assess building energy performance at the district scale, taking into account the mutual interactions of the buildings located in the same urban island. This platform is intended to promote efficient building design through an optimization process applied to the configuration of the building envelope.
