This is an exemplar energy efficiency retrofit research project. This was initiated by John Edwards when at Cadw, who is now advising on its direction and analysis. It is based on a range of tests and analysis varying from very basic common practices such as detailed surveys and EPC’s to some of the most detailed technical analysis which includes thermography, air leakage, insitu u-values, co-heating, environmental monitoring and much more. It also involves the development of a Building Information Model (BIM) which considers the potential for using BIM as a means of managing and co-odinating a wide range of diverse information. More information from BIM can be found in the RICS article.

Many of the tests and analysis will be undertaken before any repair work is undertaken, after repair and then finally after retrofit. This is intended to highlight the energy efficiency created by proper repair and then the additional energy efficiency created by retrofit. More information can be found on the Cadw website.
