Green Deal Ventilation Guidance
24 April 2013
The Royal Institute of Chartered Surveyors state that 1 in 5 UK homes are affected by condensation and mould growth. There are many factors that contribute to this; such as, poor thermal performance of the building fabric, inadequate heating, lifestyles of the occupants and inadequate ventilation.
Green Deal gives an opportunity to address these issues but can as equally exacerbate them without understanding and minimising the risks. Critically, it is important when specifying a package of fabric measures to ensure a holistic building specification approach is taken.
The overall objective when re-furbishing buildings is to create an ideal balance between heating, insulation and ventilation.
The recommended approach to a balanced refurbishment involving internal or external insulation improvements is to specify continuous ventilation at low cost and low risk.
