ANP model for sustainable Building Energy Efficiency Retrofit (BEER) using Energy Performance Contracting (EPC) for hotel buildings in China

Building Energy Efficiency Retrofit (BEER) is an attractive way toward low carbon buildings through improving energy efficiency of high-energy-consumption existing buildings. Sustainable development strategy has been reaching many spheres of human activities. Sustainable BEER aims to integrate the sustainable development concept into existing buildings and retrofit projects. To ensure BEER projects that can fulfill the sustainable development strategy, a project delivery model is one major consideration and Energy Performance Contracting (EPC) is one possible market mechanism to deliver energy efficiency projects. This paper aims to use Analytic Network Process (ANP) to develop a model for sustainable BEER under the EPC mechanism. Key performance indicators (KPIs) for sustainable BEER in hotel buildings and critical success factors (CSFs) for EPC have been identified based on a set of interview and questionnaire survey previously conducted by the authors. In this study, the relationships among sustainable dimensions, KPIs, and CSFs are identified through a focus group discussion. Finally, an ANP model is built based on the data collected in the group discussion using the SuperDecision software. ► Building Energy Efficient Retrofit (BEER) is a project to improve energy efficiency of existing buildings. ► Energy Performance Contracting (EPC) is one possible delivery model of BEER. ► Sustainable BEER is to integrate sustainable development concept into BEER. ► An Analytic Network Process (ANP) framework is developed for sustainable BEER under the EPC mechanism.
