  2. 2. Green building follows naturally from mission of non-profit developer Green building principles further AHA’s mission statement, project goals and program requirements.
  3. 3. AHA’s Key Design Principles • Long-term affordability • Client-centered, community-oriented, user-friendly • High-quality design, materials, & construction • Cost-effective development and operations • Durable and easy to maintain • Energy and resource efficient • Healthy and safe
  4. 4. Objectives of Green & Sustainable Building • Sustainable Site/Smart Growth • Natural Resource Conservation • Energy Efficiency • Indoor Air Quality • And the newest kid on the block: Reducing climate change impacts
  5. 5. Case Study: Ashby Lofts, Berkeley, CA • Southwest Berkeley- Mixed land uses • San Pablo Ave State Hwy 123 • Ashby Avenue State Hwy 13
  6. 6. Ashby Lofts-Sustainable Site • Infill site rather than greenfield development • Transportation- – TCAC = “Transit Amenities”=1/4 mile every 30 minutes – LEED = ½ mile train, ¼ mile bus, bicycles for 15% of residents • Neighborhood amenities – TCAC=Grocery, school, hospital, pharmacy, services
  7. 7. Infill site near transit • Multiple connecting bus lines, future intercity bicycle path, 1-mile from BART • Close to retail: Walgreens, OSH, future Berkeley Bowl Market • Close to Aquatic Park & San Pablo Park, Malcolm X elementary school
