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. 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. 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. Case Study:
Ashby Lofts, Berkeley, CA
• Southwest Berkeley- Mixed land uses
• San Pablo Ave State Hwy 123
• Ashby Avenue State Hwy 13
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. 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
8. Ashby Lofts- Sustainable Site
• Mixed-Use Zoning
– 54 apts- 3BR, 2-BR 1-BR, ground floor retail
• High density development
– 89 units/acre
• Parking
– 15% reduction in parking required ratio
• Brownfield redevelopment
– former asphalt processing plant

Building Design Strategies
• Exterior balconies, no double loaded corridors
• Courtyard open spaces between buildings

12. Ashby Energy Efficient Systems
• Exceeded Title 24 Energy standards by 15%
• 100% Florescent lighting
• Timers, occupancy sensors, and controls for
lighting, fans and other HVAC equipment
• Energy-efficient centralized boilers
• PV Solar electric system
• Energy STAR appliances
17. Water Efficient Systems
• Low water use plantings
• Drip irrigation
• On-site rainfall retention & infiltration
– TCAC = first 1/2inch of rainfall in 24-hr
• High efficiency toilets
– TCAC = 1.3 gpf
• Flow restrictors at faucets
24. References for choosing green
systems and materials
• Multi-family Green Building Guidelines
– Alameda Co. Waste Management Authority
• Leadership in Energy & Environmental
Design- (LEED)
• Build-it Green workshops
