Green Village Home
The Brief: To design an energy efficient home that is comfortable all year round. The owners are a retired couple and their home has been designed for aging in place.
Design Response: This two storey home has been designed around two courtyards to maximise access to northern light and to allow a direct connection between indoor and outdoor space. The use of fixed and flexible shade devices provides shading from summer sun while allowing penetration of warming winter sun.
Entry is via a glazed walk, with courtyards to the East and West, which connects the front and rear sections of the home. The front section comprises a double garage and guest accommodation. To the rear of the home are the dining and kitchen which look onto the East courtyard and the living room looking onto the West courtyard. A custom-designed staircase leads to the master bedroom with its own covered balcony and a mezzanine library with a dramatic void over the open plan kitchen, dining and lounge area below.
The home uses passive design principles to achieve year round comfort.
External wall construction is timber frame with multiple cladding selections. A breathable build wrap is used to control moisture while maintaining healthy indoor air quality. Insulation is a combination of high performance rigid foam over the timber frame and bulk insulation between studs for a total R-value of 4.5. The combined roof and ceiling insulation creates a total R-value of 5.2.
All windows and doors are doubled glazed and fitted with compression seals. Natural ventilation has been carefully factored into the design and aided by the use of ceiling fans in living and bedroom areas. Timber used during construction is Forrest Stewardship Council approved and materials have been locally sourced where possible to reduce the impact of transportation.
All electrical appliances are 5 Star Energy rated and load limiting is achieved with the help of EcoVision monitoring.
These passive design principles combine to give the home a 7.5 star energy rating.
