Components of Sustainability

1. Optimize building siting and orientation to take advantage of shading provided by natural vegetation, reduce summer heat gain, provide shelter from winter winds, and capture summer breezes.
2. Design to optimize natural lighting, provide for task lighting, and specify high-efficiency electric lighting.
3. Establish an energy budget for each project, aiming to exceed current standards such as ASHRAE 90.1-1989 by at least 25%.
4. Specify locally or regionally produced products when possible.
5. Design to minimize cut-off waste and provide for recycling during construction.
6. Specify materials and finishes with low or no volatile organic compound emissions, and provide ventilation as described in ASHRAE 62-1989 "Ventilation for Acceptable Indoor air quality."
7. When selecting products and materials, consider energy, water, materials consumption, transportation, and impacts on natural systems.
8. Minimize impervious surface and provide for infiltration and retention of storm-water to minimize contaminant loading.
9. Landscape with native vegetation, preserve natural terrain and other features.
10. Consider opportunities to provide shelter or habitat for compatible species as well as to restore waterways, vegetation, and habitats.
