Webinar: Zero carbon, resilient retrofitting for low income tenants with Alan Clarke

October 1, 2019 @ 12:30 pm - 1:30 pm


Theme – Building Services

This web tutorial, led by Alan Clarke, considers Zero carbon, resilient retrofitting for low income tenants.
North Camden Housing Coop has just retrofitted a block of 15 flats to the Passivhaus EnerPHit standard. Previously the flats were cold, damp and draughty, with low income tenants simply unable to afford to keep warm.

The retrofit wraps the building in insulation, enclosing deck access, eliminating thermal bridges and air leaks, and adds triple glazed windows and heat recovery ventilation.  Services are simple, and fully electric to take advantage of a decarbonising electrical supply. 

Previously there were gas boilers in each flat, though not all could afford to run them. Now there are electric heaters for really cold weather, but running costs will be lower than just the standing charge for a gas supply.  For hot water each flat has an electric water storage heater connected to PV panels on the roof. Surplus electricity they generate is diverted to the water heater, so with careful use free solar heated hot water will be available for most of the year.
