The objective/task was to create a
sustainable house and living
community in a designated existing
building space
Sustainability involves meeting social,
economic and environmental needs of
today without affecting future
generations’ ability to do the same.

tions From customer/client needs,
some specs identified were:
- Electricity, Proper Heating/Lighting for the houses
- Water system (good plumbing)- Structural integrity for safety- Insulation- Good quality flooring - Fire protection- Environmentally safe habitat
(no unnecessary pollution etc.)- Accessible community

Energy/Heat
Clean energy choices that met most of the criteria was:
-Solar-Geothermal-Wind
Energy Choice: Solar
• Installation- 20 kW system = $50,000
• Maintenance per household= $2,500/year
• Efficiency of panels, space (sq. m),
Geothermal energy• Installation cost= $30,000• Maintenance per year= $3,000• Average production

• The approx. total Cost calculated is 250,000 per house.
• Road system remodeling for area - $50,000
Structure= $120,000
Heating= $30,000
Waste water= $15,000
Water= $45,000
Alternative energy source= $20,000
