Planned occupancy	Advertised as Passive House with incentives to attract willing family tenant. Proposed as decant unit to act as education / demonstration through occupany.
Space heating strategy	MVHR unit with backup mains gas.
Water heating strategy	Solar water heating.
Fuel strategy	Mains gas and electricity
Renewable energy strategy	No requirement for renewable electricity to meet Passive House standard.
Passive Solar strategy	Rear south facing windows with shading / external landscaping.
Space cooling strategy	Natural ventilation combined with MVHR unit for summer cooling.
Daylighting strategy	Kitchen to achieve minimum daylight factor of 2%
Ventilation strategy	Openable windows and MVHR controlled on a room by room basis.
Airtightness strategy	External airtight membrane colocated with with external insulation layer. MMC used in bays and pre fitted replacement windows panels.
Strategy for minimising thermal bridges	External insulated panel with overlapping layers and taped joints.
Modelling strategy	Whole house modelling in PHPP 2007. Phased assessment based upon proposed sequence of interventions.
Insulation strategy	External insulation to external brick facing to achieve U-value of 0.12 W/m2K. Ceiling insulation with U-value of 0.12 W/m2K and retention of cold roof.
Other relevant retrofit strategies
Contextual information	Proposed work in advance of wider retrofit programme for the estate and informed by transferable detailing, materials and scalign of cost benefits.
