OUTLINE
• Green Practices at Carnegie Mellon
– Why
– What
– How
• Hamerschlag Hall green roof performance
assessment
• Cost implications of LEED silver certification
for New House residence hall
GREEN PRACTICES MISSION
Strive to develop university practices that
improve environmental quality, decrease waste,
and conserve natural resources and energy
REASONS FOR
GREEN PRACTICES PROGRAM
• Credibility for green practices and management
techniques we develop and espouse
• Opportunities for green design research and
education activities to use campus as
experimental or demonstration site
• Universal environmental education for campus
community
• Save money and have environmental benefit

Waste Management/Dining Services
Campus assessment completed in 2005 and
available at www.greenpractices.org
CAMPUS LIFE
• Dining Services – reduce waste volume; use
opportunity for environmental education
• Waste Management – recycling, including e-waste;
hazardous waste management
• Procurement – develop criteria and guidelines
• Communication – internal and external; develop
Environmental Center on campus
• Awards – student projects; Carnival booths
FACILITY INFRASTRUCTURE
• Building renovation and construction
– University commitment to LEED certification for
new buildings and renovations
– Partnered with green building design group
(CBPD) in Architecture
• Landscaping
– low maintenance campus gardens; native plants
– environ. progressive landscaping designs in
campus master planning effort
CENTER FOR BUILDING PERFORMANCE AND DIAGNOSTICS
An NSF Industry-University Cooperative Research Center (IUCRC)
Intelligent Workplace
The goals of the IW™ are to provide:
•User comfort and satisfaction
•Organizational Flexibility
•Technological Adaptability
•Environmental Sustainability
RAIN GARDENS
A drop of water that falls
onto CMU’s campus has an
average residency of
4 minutes
before it reaches a drain.
TRANSPORTATION
• County bus system passes
• Partnered with U.Pitt/UPMC in their carpool
program
• Established more flexible parking permits that
encourage increased bus use
• Shifting university vehicle fleet to CNG and
other alternative fueled vehicles
• Biodiesel use in shuttle buses
ENERGY MANAGEMENT
• Renewable energy: use wind power for 8%
of our electricity and other renewable sources
for additional 7%
• Converted campus heating system to 50%
natural gas supply
• Photovoltaic power supply for new computer
science facility 12kW DC
• Developing long-term energy management
plan

SUMMARY
• Methods being developed for assessing
performance of green roofs for stormwater
runoff rate/volume mitigation
• Stormwater monitoring systems being
developed for two flat green roof projects in
Pittsburgh
• Project will result in a green roof stormwater
monitoring manual
COST IMPLICATIONS OF LEED SILVER
CERTIFICATION FOR NEW HOUSE RESIDENCE HALL
N. Stegall and D. Dzombak
full report available at
www.greenpractices.org
OBJECTIVES
• Identify cost differences associated with
LEED features for New House compared with
what would have been done conventionally at
Carnegie Mellon
• Determine portion of total project cost
associated with LEED features and
certification
METHODS
• Inventoried LEED credits and associated labor,
material, equipment
• Discussed LEED features with project mgr,
architects, mechanical eng, contractors to determine
difference with “typical” CMU building
• For each LEED feature, evaluated extra cost and
compiled high/low estimates
• Performed DOE2 model energy simulations to
investigate energy savings, and effect of various
energy-saving components
