Building energy modeling (BЕM) of cultural heritage. Case study: 28 Dragoman St, Varna, Bulgaria

Abstract

: This paper presents the efforts of the team of the R&D SME Architectural Spies EOOD of creating а building energy model (BEM) of the cultural heritage building at 28 Dragoman St and 11 Bdin St, Varna, Bulgaria. Two types of BEMs are presented: based on BIM and based on FLIR thermal surveys. Know-how of producing volumetric 3D models based on 2D thermal scans is the specific scientific contribution of the authors. The BEM will be a part of AR and VR applications developed by the same team in the frames of the H2020 project BIM-SPEED (Harmonized Building Information Speedway for Energy-Efficient Renovation).
