Passivhaus for affordable housing in Fulham
We are incorporating Passivhaus Classic in several infill housing projects for the London Borough of Hammersmith and Fulham, close to our offices. 50% of these tenure blind homes are affordable so the benefits of ultra-low energy use are available to people on low incomes who struggle with fuel poverty.
We are testing two sustainable approaches to thermal comfort:
- At Farm Lane, heating is fed from a central Air Source Heat Pump (ASHP) from which low temperature hot water (LTHW) is distributed to each of the apartments via a single plate heat interface unit (HIU). Hot water is provided via hot water cylinders with integral heat pumps located in each apartment adjacent to the façade
- At Lillie Road each apartment is provided with standalone Nilan Compact P Exhaust Air Heat Pump (EAHP). The Nilan units provide heating via warm air from the inbuilt MVHR unit & exhaust air heat pump. This unit also provides cooling to mitigate summertime overheating in some spaces where windows are closed to exclude traffic noise.
The buildings follow Passivhaus design principles optimising form factor, orientation, glazing ratios, and thermal bridging. This coupled with high levels of insulation and airtightness achieve reductions in regulated emissions of around 80% against 2013 building regulations (with 2016 amendments). PV panels at roof level offset onsite carbon emissions. Coreless concrete frames and reuse of existing foundations also help lower embodied carbon.
