Crouch End low energy retrofit


This low energy retrofit to a family house in Haringey incorporates some passivhaus-inspired fabric improvements to reduce the primary energy demands of the house by 42%. The works included installing 90mm of external insulation and render to the rear and side walls of the house, upgrading existing windows by installing double glazed units into the traditional sash windows, installing new triple glazed side doors and local heat recovery ventilation units to the bathrooms. Furthermore, a solar hot water system and a 1.6kW photovoltaic array are estimated to achieve 745Kg of annual CO2 savings.
