Summary:
- Green buildings = LEED certified buildings (Leadership in Energy and Environmental Design)
- U.S. energy use distribution: 28% transportation; 26% industry; 40% building.
- Green building cost excess $3~4/sf(per square foot), but the water and energy savings will benefit $8~11/sf in 20 years, as showed below
- Other than cost are more health and learing benefits that should be took into account
- Zero-net energy cities/buildings produce renewable energy in amounts equivalent to their total energy use.
- Porous pavement are materials or techniques that allow the movement of water and air around the paving material.
- Green roofs or rooftop garden, is a vegetative layer grown on a rooftop.
- Graywater systems: graywater recycle system
- Cool roofs is one that reflects the sun’s heat and emits absorbed radiation back into the atmosphere.
- Passive lighting (Daylighting) is the practice of placing windows or other openings and reflective surfaces so that during the day natural light provides effective internal lighting
- Air sealing prevents moisture, cold drafts, and airborne pollutants from entering the residence.
- Because buildings have long expected life times, so green buildings should take precedence so that our next generation can live in energy efficient and environmental houses.
