Optimized renovation strategies of education building - A novel BIM/BPM/BEM framework

Abstract

Educational building in United State account for around 14% of overall non-residential floor area. 76.61% of education building are twenty years old or older when the major building systems and equipment reach their service life span, and 38.30% of buildings are 50 years older or older which is nearly the expected serviceable lifespan of the buildings (CBECS, 2012). The aim of this paper is to propose a novel Building information model (BIM)-Building performance model (BPM) - Building environmental model (BEM) framework to identify the most energy efficient and cost effective strategies to renovate the existing education building to achieve the nearly zero energy goal while minimizing the environmental impact. A case building is used to demonstrate the validity of framework, and a set of building performance indicators includes energy performance, environmental impacts, occupant satisfaction are used to evaluate the renovation strategies. This novel framework further demonstrates the interoperability among different digital tools and platform as well. Lastly, the case study results highlight the particular energy profile and retrofit needs of education buildings with detailed analysis and measurement.
