Energy-led retrofitting of solid wall dwellings - technical and user perspectives on airtightness
conference contribution
posted on 2012-03-30, 09:08 authored by Phil Banfill, Sophie Simpson, Victoria HainesVictoria Haines, Becky MallabandMechanical ventilation with heat recovery (MVHR) is increasingly being promoted in
the UK as a means of reducing the CO2 emissions from dwellings, and installers report
growing activity in the retrofit market. In parallel with a survey of householder
preferences and practices, the behaviour of a whole-house MVHR system installed in
an experimental house, purpose built to typical 1930s standards, has been simulated.
The range of air permeability values corresponded to those achieved in a retrofit
upgrading process carried out on the house. In the house considered, air permeability,
as measured in a 50 Pa pressurisation test, must be reduced below 5 m3/m2.h for
MVHR to make an overall energy and CO2 saving. This required a level of disruption
that would be unlikely to be tolerated by owners of solid wall dwellings.
