Lena Gardens passivhaus case study from CIBSE
Domestic energy-efficient retrofit projects do not come more ambitious than the Victorian mid terrace house in Lena Gardens. Its refurbishment had to tackle the issue of its heat-pervious solid brick walls and leaky sash windows. The task was made all the more demanding because the West London property is located in a conservation area, which prevented alteration of the building’s exterior. Despite these challenges the scheme’s designers – Refurbishment Project winners in the 2013 Building Performance Awards, Green Tomato Energy – managed successfully to transform this unpromising dwelling into the UK’s first private domestic Passivhaus-certified retrofit.
