A home for an extended family in New Providence, Bahamas

Light:
The structure runs on an east-west axis in response to the fixed pattern of movement of the sun throughout the day and year – high in the sky and ‘shade-able’ on the long south face, and minimising exposure to the low sun on the east and west faces.

Wind:
Significant breezes vary from north-easterly to southerly. A vertical axis wind turbine is proposed, situated on the eastern end. Having a vertical axis it generates power from wind from any direction. This particular model has a power rating of approximately 7,500 kWh per year.

Water:
The singular roof form allows for a central system for the collection of rainwater. One inch of rainfall on the surface area of the roof provides enough water for a six-person household for one week (assuming 100 gallons per person per day).
