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/HeatClean 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
