Sustainable Housing Project
Our goal is to build sustainable and affordable housing which will aim at meeting the housing needs of a larger community by providing better social conditions and minimizing the lifecycle environmental impacts while having a positive physical and psychological impact on its inhabitants.
When you look at the building section you'll see I was considering how the building can take advantage of natural capital including solar orientation. This provided an opportunity for a couple of sustainable design measures:
1. Natural ventilation for passive cooling - The roof geometry provides an opportunity to vent warm air out at the high point. It also aligns with the central circulation spine of the building so it will effectively collect air from all spaces and exhaust them out through louvres. The other windows in the building are lower and can be equipped with operable panels to allow cooler air to be drawn into the building. This is especially effective on the shaded north side of the building.
2. Solar Panel Array - The larger south facing portion of roof doubles as a sloped structure which is perfectly suited to house a solar array. This could provide energy for the building and depending on the size of the arrays and storage capacity in place it could also augment other facilities.
3. High Albedo surfaces - The roof, cladding and walls are design to be highly reflective. This helps to dramatically reduce heat gain from solar absorption and radiation.
4. One other measure is rainwater collection. In hot dry areas it doesn't rain much, but if we can collect and store it when it does, it can help reduce demand by quite a large amount. gutters and leaders will direct the water into a cistern below the building where it will be stored, periodically aerated and reused.
