Energy Efficiency and Sustainability at Washington University

Energy Efficiency and Sustainability

at Washington University

Hank WebberExecutive Vice Chancellor for Administration, Washington

University in St. Louis

Under Chancellor Wrighton’s leadership, increasing energy efficiency through teaching, research, and operations has been a high priority of Washington University

Over the past two decades our investment in a set of world-class academic programs has caused the number of square feet on our campuses to almost double

Despite this increase in size, we have reduced our overall energy use through a series of investments in energy efficiency and sustainability

Background

WUSTL Sustainability Goals

• Become a national leader in sustainability, both through our practices and through faculty research and knowledge-creation

• Serve as an institutional model of sustainability for other large organizations in the Midwest

• Engender a culture of sustainability on campus, particularly among our students

WUSTL Sustainability Goals

Meeting these goals requires:

Investing for long-term operational sustainability

Building a team of skilled professionals

Operational Initiatives – Context

• Washington University has over 14,000 students and 13,000 employees

• The University’s campuses cover a total of 2,300 acres and 14 million square feet throughout the St. Louis region

• WU has grown dramatically in physical size and influence in recent years

Total | 2,300 acres

Danforth Campus169 acres

Medical Campus164 acres

West, South, and North Campuses

Operational Initiatives – Focus on GHG Emissions

• Greenhouse gases are an increasingly critical issue to the United States and the world; our operational initiatives have focused on reducing our GHG emissions

• We have primarily focused on two of the largest contributors to GHG emissions: energy use for heating and cooling and transportation

Energy Use (MMBTU)

Building A

rea (GSF)

Since 1990, WU’s square footage has doubled, but overall energy use has decreased 4%

Energy Efficiency Legacy

Without investments in energy efficiency, would have seen an 88% increase in energy use rather than a 4% decrease

Focused on four main areas:

• Utility efficiency

• Building efficiency

• Culture of energy awareness

• Renewable sources of energy

Energy Efficiency Initiatives

• Switched from coal to gas

• Central plant conversion to distributed thermal plants

• Thermal and chiller plant upgrades

• Proactively replaced old, inefficient systems

Utilities | Energy Efficiency Progress

Kemper Art Museum Heat Recovery Chiller

• Recently completed installation of utility meters in all buildings

• Allows us to target high energy use buildings and allocate actual energy usage costs

• Better monitor equipment efficiency and identify performance problems

Utilities | Energy Efficiency Progress

• LEED Record

• 1 Living Building Challenge (Tyson Living Learning Center)

• 2 Platinum under construction or pending

• 7 Gold (additional 3 pending)

• 7 Silver (additional 1 pending)

• 3 Certified

• Recently installed additional 379 kW of solar generating capacity

Renewables | Energy Efficiency Progress

Tyson Living Learning Center

Brauer Hall

• Student energy reduction competition

• Green Labs Initiative

• Green Offices Program

• Less is More campaign

• 30 student “Green Ambassadors” conduct hundreds of hours of peer-to-peer outreach each year

Culture | Energy Efficiency Progress

Green Cup Student Competition

• Partnership with Metro provides free access to the entire MetroLink system for all full-time faculty, students and staff

• $2M annual investment by the University

• Extensive alternative transportation options to encourage students and employees not to drive to campus alone

• Investing in extensive bike infrastructure within and throughout campus

• Extended Great Rivers Greenway trail through the Danforth Campus

• Developing comprehensive bike/pedestrian campus master plan

Transportation Initiatives

• In 2012, we committed to invest an additional $30M in energy efficiency projects by 2020

• All implemented projects will be NPV positive

• These projects are projected to reduce emissions by more than 50,000 metric tons of CO2; this is equivalent to permanently taking 10,417 cars off the road

• We estimate that we will save $5.4 million annually in energy costs as a result of these investments in sustainable operations

Sustainability is Good Economics

• Ultimate goal of the University is to be a leader in energy efficiency and sustainability through the methods of teaching, research, and operations

• Sometimes we are able to bring all three of these methods together in a single, holistic project

• Quadrangle Green Rehab Project

Campus as a Laboratory

Quadrangle Green Rehab Project

• WU has committed to building new buildings so that they are efficient as possible

• Majority of emissions come from existing buildings that will not be replaced by new structures; how can these existing buildings be renovated to be as energy efficient as possible?

• Quadrangle Green Rehab Project uses teaching, research, and operational methods to look for best practices in green rehabs

• Interdisciplinary team including faculty researchers, students, Office of Sustainability, and real estate team

• Students and faculty from multiple schools involved in design of renovations and post-renovation energy usage research

Quadrangle Green Rehab Project

• Project design

• Quadrangle Housing (off-campus real estate group) identifies pairs of nearly identical apartment buildings in need of renovation

• One building from each pair receives a traditional rehab, the other receives aggressively green design

• Once renovations are complete, faculty and students will track energy use from each building to gain understanding of the true value of investing in high-efficiency upgrades

• 5 year program, started in the Fall of 2012

• First pair of buildings are under construction

• Second pair of buildings have been identified, are being designed

Quadrangle Green Rehab Project: Phase 1

• Increasing energy efficiency has been a long term priority of Washington University

• Over the past decade, significant efforts have been made to maximize our sustainable initiatives while reducing our carbon footprint

• We have made great progress – but we continue to search for opportunities that will further increase energy efficiency
