Colour and delight in a fully Accessible Liveable Sustainable Home.
In this era where natural resources are under threat of depletion, it is not surprising that people start adopting energy efficient and green living. Green architecture is the part of the same campaign. People are building homes that are self-sufficient and environmentally friendly.
Designing a sustainable building for energy building efficiency and low on-going maintenance requires early consideration at the beginning of the house design; at Concept Design. This was the challenge the clients put forward to BP Architects in designing the Essendon home, as well as making the home fully accessible for a motorized wheelchair.
A Brief Description
The home positioning on the south boundary, the use of recycled timber, rainwater tank and water conservation were given due consideration during the designing of the Essendon house. The house was designed to have little dependency on artificial light, heating and cooling.
‘Only on the coldest consecutive winter day the localized bar heater is used at half the maximum heat, for a few hours to maintain comfortable air temperatures’. Dorothy Hatch, Owner, Essendon home
Detailed Feature Description
The main focus while designing this house was to make it fully accessible for wheelchair access, energy efficient and to incorporate green architecture with low maintenance.
Windows were placed high with sky views and the ability to open, allowing for good ventilation and exhausting stratified hot air during the night. Windows on the north were designed in the master bedroom to keep the room warm.
Tiled flooring was installed adjacent to the windows, allowing for the thermal mass of the slab to maximize the absorption of passive solar thermal heat. The thermal mass helps maintain constant and comfortable indoor temperatures.
The Weather Conditions
Located in an inner city suburb, and surrounded by brick walls and fences, the house was protected from exposure to heat loss from winds. The positioning of the house, away from the north boundary on the south boundary, optimized for north sunlight. This ensured that the house received maximum solar heat from the north glazed façade during the winter season.
The sustainable building and green architecture features include air transfer ducts, which facilitate the transfer of warmed air from one room to another. As hot air rises, warmed air at the ceiling level of the living areas is transferred to the cooler bedrooms with ducted fans. High windows are located throughout the house to exhaust hot air during the summer months.
Ceiling Fans have both summer and winter modes so they move the heated air that rises to the ceiling in winter to the lower levels and provides air movement for comfort during summer. The solar pergola and sun shading ensure that you have the winter sun when you want it and they shade the house from the summer sun to help keep the home cool.
The thermal mass in the floor slab acts as a heat sink absorbing the heat from the sun. The tiled flooring adjacent to north windows ensures that the maximum amount of thermal heat is absorbed into the slab.
The In-Ground Rainwater Tank provides water for toilet flushing. An on-demand recirculating hot water ring means that at a flick of a switch the cold water that is sitting in the hot water pipes is returned to the storage tank and you have hot water when you want it, without having to waste water until it heats up.
These features, and more, ensured that the house is a sustainable energy efficient home.
While a great example of green architecture, the design of the house provides a sense of space and volume. Flexibility is implemented into the planning so that spaces can be open and closed, increasing air volumes, as required by weather conditions.
