C048 -- Decision Support Framework for the Retrofit of Public Buildings for Energy and Carbon Reduction

Sustainability in the building industry is precipitated by climate action targets like the United States’ goal to be carbon neutral by 2050. Retrofitting the country’s existing building stock is vital to meet these goals. This paper proposes a practitioner’s approach to maximize retrofit impact for government-owned public buildings. Based on energy modelling results and heuristic input from sustainability consultants and stakeholders, a decision-support framework is proposed, and illustrated through a case study. The intent of this framework is to assist decision-makers with informed prioritization of retrofit interventions, keeping in mind the temporal complexities of funding and political considerations.
