Design strategies

Planned occupancyStandard PHPP occupancy assumptions used
Space heating strategyMonobloc air source heat pump and wet radiator systems
Water heating strategyMonobloc air source heat pumps, with immersion backup on hot water cylinder
Fuel strategyDirect electric
Renewable energy strategyAir Source Heat Pump
Passive Solar strategyPlots oriented to take advantage of solar gain within the constraints of the site.
Space cooling strategyDesign optimised within PHPP- oveheating frequency within Passivhaus requirements, utilising MVHR in bypass and natural ventilation.
Daylighting strategy
Ventilation strategyPassivhaus certified MVHR unit providing continuous ventilation.
Airtightness strategy Parge coat on blockwork, Smartply Propassiv to ceiling, all junctions taped with Proclima products and specialist grommets used where required.
Strategy for minimising thermal bridges Design reviewed and junctions optimised to reduce thermal bridging to a minimum.
Modelling strategyPHPP used at all stages of design to assess performance and test options.
Insulation strategy
Other relevant retrofit strategies
