Design strategies

Planned occupancyThese are private sale and the occupancy is unknown.
Space heating strategyEach unit has an individual condensing mains gas boiler to water filled radiators
Water heating strategyEach unit has a combined condensing gas boiler, providing instant hot water.
Fuel strategyMains Gas as primary heating source, and mains electricity.
Renewable energy strategyNo renewable electricity generation.
Passive Solar strategyAll units modelled in PHPP for orientation, generally windows sized sensibly.
Space cooling strategyOpening windows, plus some cooling via MVHR in summer bypass mode.
Daylighting strategyNo particular strategy given.
Ventilation strategyMechanical ventilation with heat recovery for background ventilation, opening windows for purge ventilation, and summer cooling.
Airtightness strategy Ensuring properly detailed junctions and site supervision and on site inspection with signed check list sheet. Airtightness membrane to roof, with airtightness tapes to joints.
Strategy for minimising thermal bridges Some thermal bridge analysis undertaken, Continuous insulation maintained whenever possible, with an on site inspection and check list sheet to ensure compliance. Junctions assessed include: foundations and internal load bearing walls at ground.
Modelling strategyPassive House Planning Package used to model energy strategy.
Insulation strategyWall U value = 0.15 W/mK. Roof U value =0.09w/mK. Floor U value = 0.13W/mK
