Energy Use

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.

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.
