Sustainability – the basic concepts
EnvironmentDevelop a site to minimize the
impact of intrusion and use building materials efficiently to
avoid depletion of natural resources
Sustainability – the basic concepts
EnergyDesign a building to be as energy
efficient as possible using life cycle cost analysis of energy
sources and avoiding greenhouse gas production
EquitySelect building materials that
support the local economic system

the facility
Built Environment
U.S. buildings use:
70% of electricity produced
39% of primary energy produced
12% of available potable water

U.S. Green Building Council1993
• Facilitate positive results for the environment, occupant health and financial return• Define “green” by providing a standard for measurement• Prevent “greenwashing” (false or exaggerated claims)• Promote whole-building, integrated design processes
U.S. Green Building Council1993
• Use as a design guideline• Recognize leaders• Simulate green competition• Establish market value with recognizable national “brand”• Raise consumer awareness• Transform the marketplace
Leadership in Energy and Environmental Design - 1998
• Sustainable Sites• Water Efficiency• Energy & Atmosphere• Materials & Resources• Indoor Environmental Quality• Innovation & Design
Existing buildings = 90%+ of campus structures
The University as a Mini-City(University of Puget Sound)
Sustainability - the existing building
Ethical Reasons:
Demonstrate positive environmental stance – “That’s the kind of company
we are” (philosophical)
Sustainability - the existing building
Mandated Reasons:
External – from governmental requirements
Internal – corporate policy
Sustainability - the existing building
Business Reasons:
Reduce operating costs, better operations and maintenance, energy
and resource savings – as much as 25-50% energy savings
Increased productivity – tough to quantify, but ranges have shown from
1%-16% increases
Sustainability - the existing building
Business Reasons:
Higher tenant attraction factors, lower turnover rates
Lower tenant (renovation) churn
Building occupants, including students, demanding healthier spaces
Existing Building Renovations
LEED-NC 2.2(uses common measurement for new and existing buildings – many points unachievable when new vs. existing)
Existing Building Renovations
LEED-EB 2.0(focus on envelope, finishes, and
building system upgrades, maintenance and operations, and
green building cleaning)
Existing Building Non-Renovations
LEED-EB 2.X(new focus on maintenance and
operations, commissioning, recycling, and green building cleaning)
Replacing incandescent bulbs with CFL’s = 75% savings in electricity use
and $30-$50 in energy costs over lifetime of the lamp
Building commissioning = $0.27/sf produces 11 deficiencies with payback
period of 9 months
Existing Building Non-Renovations
Use of green, or renewable, non-polluting energy = reduces demand for foreign oil resources or use of polluting
coal burning furnaces(wind, photovoltaic, geothermal, solar
and bio-mass)Tacoma Power = 86% hydro (non-
polluting)I-937 requires obtaining 15% of new
energy from renewable sources
Existing Building Non-Renovations
Existing Building Renovations
With existing buildings aren’t the LEED processes difficult to accommodate,
expensive to implement, and cumbersome when responding to the
desired building functions?

What can you do?
Facilities – make a commitment to renovate buildings and reap the rewards the business decision
provides. Consider:LEED-NC or LEED-EB Programs
Energy Star ProgramsCampus-wide initiativesVarious grants availableReduced insurance rates
What can you do?
Educators – import or develop programs to inform today’s
students about the changing world. Consider:
Ecological/environmental coursesPartner with industry specialists
(AIA, USGBC, SBA, etc.)Educational grants available
What can you do?
Students – get involved, become knowledgeable about your world, request changes to the campus
environment. Consider:USGBC Emerging Green Builders
(student organization)Green Drinks Events
