This paper presents the findings from building performance evaluation studies of two deep retrofits in UK – Victorian house and Modern 1990s house. Both case studies were designed to achieve 17 kgCO2/m2/year (equivalent to 80 % reduction) and adopted a fabric-first approach. Post-retrofit, it was found that the Victorian house achieved a 75 % CO2 reduction, while the modern house achieved 57 % CO2 reduction over the baseline. Key reasons for these are higher than expected air-permeability rates of the building fabric post-retrofit, lack of occupant understanding in operating low carbon technologies and unusual electricity using behaviors of occupants particularly in the modern house.
