Abstract: A major source of heat ingress in existing-buildings is through the envelopes. A bulk of cooling load in existing-buildings can be reduced by energy-efficient retrofitting of Roof, Walls and Fenestrations. The methods available for calculating heat ingress in largescale existing structures are lengthy/cumbersome and manually impractical. The popular energy simulation software is black-box type requiring specialized technical skills, voluminous data-entries, several iterations and does not automatically select the most energy-efficient envelope retrofitting material out of available options in the local market. This paper proposes a user-friendly spread-sheet based model of a tool for automatically selecting energy-efficient envelope retrofit solutions from the available options.
