Build Green
• What is Green Building?• Why Build Green?• Rating Systems for Green Buildings• Benefits
Green Building Occupants Are Healthier & More Productive
• In the U.S., people spend on average 90% or more of their time indoors*
• Indoor pollutant levels may be 2 – 5 times higher than outdoor levels
• EPA ranks poor Indoor Air Quality (IAQ) in the top 5 health risks**
• Costs to Americans estimated at: – $1.5 billion in medical bills – Tens of billions in lost productivity &
absenteeism• LEED certified project case studies illustrate 2 - 16 %
increased worker and student productivity* **
What are the rating systems?• LEED (US)• BREEAM (UK)• CASBEE (Japan)• DGNB (Germany)• Green Star (Australia)• IGBC/LEED (India)
LEED (Leadership in Energy and Environmental Design)
• Created by the U.S Green Building Council (USGBC) in 1998
• Nationally recognized standard for Green Building
• Adapted for other countries– Canada– Australia– Hong Kong
LEED 2009
An analytical basis for point allocation.
An extensible analytical foundation to address new issues and new green building strategies.

recycling 92 percent of construction-related
debris
solar panels to reduce energy used to heat
the building
glass for natural lighting
automatic window shades to limit
exposure to heat and cold
high-performance terra cotta and
recycled insulation on the exterior walls
Installing chilled beams cooled by
groundwater in warm areas
Why the Demand?
• Unprecedented level of government initiatives
• Heightened residential demand for green construction
• Improvements in sustainable materials

1. Plants will grow in boxes on a mechanical track that carries them from the top of the building to the bottom for harvesting
2.Mechanical arms below the track will gradually shift the boxes forward on each level
3. Leafy vegetables will be planted in the boxes in pumice to hold water.An irrigation line will carry water and nutrients to the roots.
