Fraise House
Project team: John Christophers at Associated Architects; Shire Consulting for Structures; PMP for Quantity Surveying; LEDA MEP and energy engineering.
Bespoke low energy dwelling using structural insulated panels (SIPs) with ground source heating.
LEDA applied Passive House principles using PHPP, modelled thermal bridges and designed the building services for this replacement dwelling with ground source heat pump and renewable energy generation.
Passive House Design
With high levels of insulation and an airtight construction strategy, the building will perform close to the Passive House level of performance. A mechanical ventilation with heat recovery unit will provide continuous fresh air to the building with secure natural ventilation provided for summer cooling.
Selecting effective sustainable technologies
Heating will be delivered through underfloor heating in the open plan spaces and master bedroom and towel radiators in the bathrooms. Heating and hot water will be supplied by a ground source heat pump extracting heat from a bore hole under the front driveway. The house will have roof integrated solar PV panels generating a high proportion of the operating energy during spring, autumn and summer.
High impact, low energy lighting as part of the architectural concept
Unlike commercial spaces, lighting requirements for residential use are far more subjective. Recessed LED strips have been used to wash down wall planes creating diffused and glare free illumination in the rooms. Lighting plots were used to evaluate where additional movable lighting may be required to supplement this minimalist scheme.
