Details

The aim of the DEEP project was to investigate taking a system-level approach to retrofit, considering the entire dwelling rather than the performance of individual measures. Typically defined as a 鈥榳hole-house鈥� approach, this appreciates the complex interactions between fabric, ventilation and the occupant.

The literature review summarises the existing knowledge in this field and provides the evidence to justify the research strategy adopted in fulfilling the objectives of the project.

The results from field trials, laboratory testing, and extensive modelling investigations have produced a series of complementary findings that paint a picture of performance and risk for piecemeal and whole house approaches to retrofitting solid walled homes.
