Retrofit of existing housing stock. A feasibility case study.

lsrael not unlike other Mediterranean country , experienced a housing construction boom in the 1950s and 1960s. Many projects from that period are currently undergoing renovation and refurbishment. This study reviewed the thermal characteristics of such projects and evaluated the current refurbishment practices vis-a- vis a combined effort including retrofit. Different solutions for a specific case study were evaluated. The results point toward a vast savings potential in energy consumption on the national level, as well as to marginal savings for individual customers, which such solutions provide at current energy prices in Israel.
