“Greening” Purdue
• The energy and environmental impacts of “business as usual” have led to a heightened interest in sustainability
• Physical Facilities is taking the lead in exploring opportunities to “green” our campus
– Sustainability Council (www.purdue.edu/sustainability)
• Buildings are a huge contributor to our energy and environmental impact

Buildings consume 40% of the US energy supply
12% Water Use
30% Greenhouse Gas Emissions
65% Waste Output
70% Electricity Consumption

Benefits of Building “green”:
4
• Reduced energy usage and peak demand
• Reduced resource consumption and less waste
• Improved indoor environment
• Process ensures a verified high performance building
• Marketing value
• Demonstrates sustainable leadership

Building Green at Purdue:
We receive direct economic and environmental payback for our efforts…“We are our own customer”
• The energy and environmental impact of Purdue is associated almost solely with our buildings
• Green buildings have: – 30% lower energy use:
• ↓ cost • ↓ greenhouse gas and other emissions
– 30-50% lower water use • ↓ energy for water supply • ↓ sanitary sewer costs
– 50-90% lower waste production • ↓ waste disposal cost

What is LEED ?
6
®
• “Leadership in Energy and Environmental Design”
• Voluntary rating system for sustainable buildings
• Launched by the U.S. Green Building Council in 2000 (www.usgbc.org)
• Public demonstration of commitment • The metric for high performance buildings • Continually changing

Water use reduction LEED points are appropriate to most projects at Purdue
Measurement & verification of energy particularly appropriate to Gatewood Mechanical engineering project
Due to its location, daylight and views not as appropriate to Roger Gatewood project
LEED allows leveraging of project strengths

LEED Building Policies in Government
11
• Indiana Executive Order Final Draft titled: “Establishment of Energy Efficient State Building Initiative”
– “All new State buildings, including…public universities, shall be designed…to achieve maximum energy efficiency to the extent this can be accomplished on a cost effective basis…over the life cycle of the building.”
– “… “Efficiency” may be demonstrated through design which achieves:
• The silver rating under the LEED rating system;
• (other equivalent rating systems)
– “Repair or renovation of all existing State buildings shall be designed to achieve maximum energy efficiency to the extent this can be accomplished on a cost effective basis, considering construction and operating costs over the life cycle of the building.
• HB1380 “Energy Efficient Buildings” is currently under consideration – “for the construction, reconstruction, repair, alteration, or retrofitting of a university owned
building or structure
– Goal of LEED Silver or equivalent
– Value of project: at least $1 million

LEED Costs for Gatewood
12
Total Cost: $34.5M
LEED Administrative Costs ($0.5M) Elements of project directly attributable to LEED ($1M)
Note: Many project elements are not unique to LEED but are industry “best practice”.
![Page 14: Discovery Park Energy Center Green Building Workshop ......LEED Silver targeted Discovery Park Energy Center Green Building Workshop January 22, 2009 Luci R.

LEED Payback for Gatewood • $26K →Annual energy cost savings • $185K →Avoided utility plant infrastructure cost • $493K → Smaller building mechanical, electrical,
plumbing systems
• 16 year payback for Gatewood LEED cost
• Additional Benefits – Lower operating costs with commissioned, measured, verified
energy systems – Increased productivity of occupants from improved indoor
environment not included in economic evaluation

Summary
14
• Buildings are a huge part of our campus’s energy and environmental footprint
• Sustainable building practices are especially relevant to university buildings
• LEED is the current metric for sustainable buildings
• Pursue LEED where beneficial
• LEED is more than a plaque on the wall
