Principles of sustainable sites
1. Reduce negative impact of buildingson the natural environment
• Minimize earth disturbance• Retain green cover• Minimize light pollution• Minimize impervious coverage

Principles of sustainable sites2. Reduce energy consumption through
building orientation
• Natural ventilationShielding from winter windsPromoting cross ventilation
• Passive solar heating• Shade cooling• Daylighting

Conclusions
• Select sites with least impact on natural environment
• Select sites with greatest opportunities for passive heating and cooling
