Summer 2001

Improving a university’s operations environmentally has only recently received attention. Universities around the country are in different stages of improving their operations environmentally. This report looks at local universities as well as the “Top 25 Universities in the Country” as defined by U.S. News and World Report. The purpose of this report is to present information about what other institutions are doing in order to provide Washington University insight.This report looks at howWashington University is currently operating environmentally and at what different academic departments are doing in terms of research on environmental issues.


Part I: What other Universities are doing

Similarities the Universities share:

For most universities the Facilities department is responsible for recycling. There is a recycling or energy conservation department within facilities that handles recycling. Energy services handle conservation and is either apart of Facilities, Operations or Utilities. While it was difficult to find information on energy conservation, most of the universities contain detailed information and examples on the environmental and economic benefits of recycling, reducing and reusing items. Comprehensive plans on how to recycle and what to recycle are also given. Two of the best sites are www.uos.harvard.edu/fmo/recycle/overview.html, and http://www.facilities.yale.edu/Who/Recycle.asp.

Items that most universities recycle are: aluminum cans, separated PETE #1 and HDPE #2 Plastic; white paper; colored paper; envelopes; manila envelopes; telephone books; glass; laser toner; inkjet cartridges; cardboard; batteries; Styrofoam packing peanuts; transparencies; scrap metal and wood; fluorescent light tubes; computers and other electrical appliances; office furniture; and clothing. The money collected from recycling is usually used to help fund the recycling program.

Waste reduction comes about by purchasing materials with minimal packaging and making sure that paper or other products are not used in excess of actual needs. Tips on waste reduction include: using both sides of a sheet of paper; purchase long lasting, durable products; buy in bulk when possible; purchase recycled toner cartridges; reduce the amount of unnecessary packing; attempt to buy refills as opposed to a new product (for example: liquid soap refills instead of new liquid soap dispensers); reuse bags, containers, and other items; borrow, rent, or share equipment or tools used infrequently; and sell or donate goods instead of throwing them out.

Many universities also support recycling in their purchasing activities, and by encouraging conservation of electricity and water. Many also provide information on energy and water conservation such as replacing all regular showerheads with low-flow showerheads; water flow restricters in every campus toilet and urinal flush valve; a computerized Irrigation Management System that, based on weather data, controls the watering of large landscape areas on campus; installing compact fluorescent light bulbs in dormitory hallways and rooms; urging students to use more energy efficient room lighting; installing motion sensors in campus bathrooms; purchasing energy-efficient computers; and incorporating passive solar design in the construction of new buildings. Two of the best sites are http://www.stanford.edu/group/enviro-reps/res.actions.html and http://www.princeton.edu/~perc.

Part II: What Washington University is doing

In an interview with Ralph Thaman, Associate Vice Chancellor - Facilities Planning and Management, Ed Barry, Assistant Manager - Capital Projects and Records and Edward McMullin, Manager of Technical Operations, the following information was learned:

Facilities Planning and Management is committed to saving energy at Washington University. The University’s utility costs have remained essentially flat over the past nine years even though the School has experienced a 25% increase in building area. Some of the energy saving methods employed by the Facilities Planning and Management Department are as follows:

Lighting:

The use of energy efficient lights (T8 lamps) and high efficiency electronic ballasts on existing and new lighting fixtures has dramatically reduced electrical energy consumption. These devices require less energy for lighting.

Interior lighting is limited to 2 watts per square foot maximum. This lighting level has proven to be adequate for normal lighting applications. During the design of new buildings and renovations, extensive design reviews are conducted to ensure that lighting levels do not exceed standards.

Motors:

Energy efficient motors are used to reduce the amount of electricity required to drive large equipment like fans, pumps and chillers.

Variable speed drives are used on fan and pump motors to match the speed of the motor to the actual demand, thus saving electricity at off-peak loads.

Boilers:

The current decentralization program of the main high pressure boiler plant into a series of small low pressure boiler plants will reduce fuel consumption by placing boilers closer to the loads, thus minimizing steam losses in the distribution system. The separation of the South 40 from the main boiler plant and the installation of a dedicated hot water boiler plant at the South 40 is one example of this decentralization program. Currently, Thermal Plant #2 (McDonnell Hall) and Thermal Plant #3 (Snow Way Garage) are being built and will be in full operation this fall. Future plants will be built at the Bio-Medical Building, the VADC complex and the new University Center.

The operation of the main boiler plant was changed about ten years ago by shutting down the boilers during the summer months, thereby eliminating the mismatch between boiler capacity and summer heating loads and the corresponding inefficiencies. Small “summer” boilers were placed in individual buildings to provide steam/hot water for summer heating requirements.

Chillers:

High efficiency chillers are used to minimize the electrical power required to produce chilled water for air conditioning.

Digital control systems and automatic valves are used to allow colder condenser water temperatures during cold weather, thus improving chiller compressor efficiency and reducing electrical consumption.

Cooling tower fans are cycled on and off based on demand thereby saving electrical energy.

HVAC:

In the design of new buildings and renovations, space cooling and heating loads are limited to a maximum of 20 btuh/ft2 and 15 btuh/ft2, respectively (British thermal heating units). Design reviews are held to verify that these levels are not exceeded. Maintaining these levels reduces electrical and fuel consumption required for cooling and heading, and also reduces the size and first cost of equipment. Occasionally, architectural and/or space programming changes are made to maintain these levels.

Outside air for ventilation of labs is kept at minimum required levels to conserve energy. In a conditioned building, outside air must be cooled or heated to the inside temperature. On hot or cold days, this can equate to a significant load on the HVAC systems. Ventilation air for labs is minimized by shutting down fume hoods when not in use and by incorporating low velocity (60 fpm) fume hoods that require less exhaust air for safe operation.

Ventilation air for people is maintained at minimum levels as required by ASHRAE. Demand ventilation using CO2 sensors is being used to provide only the amount of air that is required based on occupancy. This limits the amount of outside air during periods of low occupancy to prevent wasted energy. Night setback modes are also used to shut down HVAC equipment at night when buildings are closed.

Outside air/exhaust air heat recovery systems are used to recover the heat in exhaust air before being discharged from the building. This captured heat is used to pre-heat or pre-cool outside air before being brought into the HVAC systems. This reduces steam and chilled water demands thus saving fuel and electricity.

Low-e (emmisivity) glass coatings are used on all windows of new and renovated buildings to limit the amount of solar heat from entering the interior space, thus minimizing the demand on air conditioning systems.

Pollution:

The conversion of the main boiler plant from coal to natural gas has significantly reduced emissions, ash and soot and has also eliminated the need to retrofit the plant with costly pollution control equipment.

Most chillers have been converted from ozone depleting chlorofluorocarbons (CFC’s) to environmentally friendly hydrofluorocarbons (HFC’s).

Additionally, Facilities Planning & Management coordinates with AmerenUE during peak energy demand periods. Facilities decreases energy use in non-essential buildings so AmerenUE can continue to provide energy to area homes. Facilities employs many energy saving methods to keep the University powered while reducing energy usage and costs. Updated technologies and improved efficiencies have improved the reliability and capacity of the utility systems.

The Facilities Planning and Management page contains the following information about recycling:

Recycling is a volunteer program that depends upon each individual contributing to the belief that recycling is a necessity. Containers are located throughout campus. Follow instructions on the containers and the guidelines for paper recycling.

Paper Recycling Information:

Acceptable Paper:

Letterhead Stationary—any light color (no fluorescent, reds or other dark colors), Photocopy paper—any light color, Typing paper—any light color. Envelopes–any light color but brown, plastic windows are acceptable, carbonless duplicate invoice and NCR forms, computer paper, legal pad paper—any light color, chipboard back of pad is NOT acceptable, post-it notes, no bulk amounts, a minimum combined in with other office papers is fine. (Staples are acceptable, but please remove paper clips and reuse them!)

Unacceptable Paper:

Kraft paper (i.e. brown bags, envelopes, packing paper, etc.), newsprint, phone books, slick magazines or catalogues, paper plates, cups or food wrappers, any other shiny or glossy coated paper, plastic, carbon or blueprint paper, copy paper wrappers (they are coated to resist moisture), rubber bands, clips, etc., groundwood computer paper, self-sealing or reusable adhesives.

In an interview with Steve Hoffner, Assistant Vice Chancellor for Students/ Director of Operations and Karen Grimes, Assistant to the Director of Operations the following information was learned:

CEQ, the Committee on Environmental Quality, is leading the Living Responsibly efforts. Faculty, staff, students and representatives from the student organizations of the Sierra Student Coalition, Green Action, Progressive Action Coalition (PAC), and the Jewish Environmental Initiative (JEI) are on the committee. Their Web site address is www.ceq.wustl.edu . CEQ “allows members of the Washington University community to voice their concerns regarding environmental problems on campus and work together to solve them. We strive to preserve and improve overall environmental quality, implement plans for sustainable development, and heighten environmental awareness.”

The educational component of the effort is multifaceted. Nate Dewart, the new recycling coordinator, will be spearheading the educational efforts, and will also oversee the day-to-day recycling operation in cooperation with Grounds and Housekeeping. One part of the educational component involves meeting with the different schools and with the community to encourage participation in Living Responsibly. CEQ will be visiting each residential floor during the first Residential Advisor’s meetings. There will be signs in every room/suite (on the back of the main door) on campus with details on how one can live responsibly. The sign contains information about reducing waste and energy consumption.

Turning lights on and off can waste more energy than simply leaving them on. Turn off lights in areas when they are vacated for the night or for extended periods of time. Maintaining a consistent temperature in a room reduces excess stress on the heating and cooling systems of the buildings. Make sure the temperature in a room is at a reasonable setting and leave the fan on low. Keep windows closed when the system is on. Make double sided copies. Take advantage of the paper and toner-saving feature on most printers and the power-saving features available on computers and monitors. Only take as many amenities as needed from dining areas. Avoid allowing water to run when applying soap, brushing teeth, etc.

For reusing: avoid purchasing disposable cups, flatware and silverware: purchase reusable items and wash frequently. Use the provided reusable WU dining services mug and save money. Use a hand towel instead of paper towels. Keep your Bear’s Mart bags and bring them back with you when you return. Use the back of paper you no longer need for rough-draft printouts, messages, reminders, etc.

For recycling: recycle bins are located in buildings throughout the South 40 and Hilltop campus. Familiarize yourself with the various groups of materials, which can be recycled. We recycle commingle: plastics # 1 and #2, glass, aluminum and steel (remove lids and rinse containers first); mixed paper: office (white paper) and light colored paper; and newspaper: newspaper, inserts, magazines, phone books, Ternion, course listings.

Also, as part of the educational component CEQ and Dining Services will again be distributing mugs to all campus residents to help with reduction and reusing. People receive a to-be-announced discount off fountain drinks and a $0.05 discount off other drinks every time they use their mugs and additional mugs are available for purchase in the Mallinckrodt food court for $ 3.49.

CEQ has a budget of ten thousand dollars for the year. They are buying approximately 30 recycling containers for classroom areas and for other heavily- used buildings such as Mallinckrodt, Millbrook, Fraternity Row and the Olin Library exterior areas. There will also be a recycling container at Holmes Lounge. The containers are made of recycled materials such as plastic chips. The containers will be labeled commingle: aluminum, glass, plastic; newspaper; and mixed paper. There will also be a container for cardboard collection at Wohl and Mallinckrodt. During the move-in days there will be a cardboard container in the swamp as well. There are labeled recycling containers in each residential hall for students to place recyclables. There are labeled recycling containers outside of the residential halls where Grounds and Housekeeping will place recyclables. Mid-West Waste picks up the recycling and Resource Management sorts it. The committee is researching the possibility of having a receptacle at Wohl for students to place plastic bags. The Grounds and Housekeeping staff will receive training about handling the recycled materials.

Bon Appetite and Dining Services are offering paper plates and 16 oz. paper bowls beginning in August. The paper has a finish that makes it more durable. The cups have a textured feel and will withstand the walks between the dining facility and home/office/class. The dinnerware does not get soggy. The items are to be placed in the mixed paper containers. There are signs up in Ursa’s asking customers to consider how much packaging and napkins they really need. Subway employees also ask customers how much packaging they need. CEQ and Dining Services are also working on additional ways to reduce wastes.

Paul Norman, the University Horticulturist 935-4533, is in charge of the yard composting. Top Care shreds and takes leaves, tree limbs and occasionally the clippings from lawn mowing to the compost facilities, St Louis Composting Inc., 39 Old Elam Ave, Valley Park, MO and Route 66 Landscape Supply Center, 18575 US Highway 66, Pacific, MO. The compost in the form of mulch is then returned to campus. Large trees are cut into logs and donated. Washington University does not compost on campus because Clayton ordinances require that composting be kept out of sight, out of smell and rodent-free. CEQ is researching the feasibility of having food compost.

Curt Harris 935-5076 is the supervisor of housekeeping. The common rooms of Gregg Nemerov, Shepley, Wheeler, Park and Mudd have curbside recycling containers that have one divider. The students are responsible for putting their recyclables in the big recyclable containers in the trash rooms on each floor. All of the freshman dorms have smaller containers in their rooms and are responsible for putting their recyclables in the big containers in the trash rooms on each floor.

Dauten, Shandeling, Rutledge, Hitezman, Hurd and Meyers have recycling containers in the trash rooms on each floor for newspaper and cardstock. The suites have small containers in their rooms for co-mingle and housekeeping empties these containers once a week. The students do not empty these because of safety concerns with the stairwells. Some students in the sophomore suites have contaminated the recycling containers and the trash rooms have had to be locked. It is imperative that students take recycling seriously and not contaminate the containers. Nate will also be working on this issue. Millbrook and Small Group Housing will have the curbside recycling containers in the common areas. The students in Small Group will put their recyclables in containers in the trash rooms and Millbrook students will empty theirs into the containers outside of their buildings (they also empty their own trash).

CEQ coordinates with Purchasing and with Bon Appetite to purchase green products such as recycled paper. Individual departments are working to reduce wastes and Nate will be compiling more specific information. There is an annual phone book recycling program and the proceeds are donated to a not-for-profit organization. Transportation offers a discount Bi-State pass that is valid for one semester

The July, 2001 College Planning and Management Campus Scene section had an article on Washington University: Washington University’s Energy Efforts Save Money.

In the past eight years, Washington University in St. Louis has added 500,000 square feet of facilities, but has kept its budget flat—$5 million—for all energy costs. There are several reasons for this, notes Susan Gallagher of Ameren Corp. All buildings use energy-efficient lighting—no more than two watts per square foot. Administrators are using Ameren Abacus, a wireless energy management/monitoring tool that involves installation of ratio-based meters. They have seven meters that monitor use, allowing them to identify areas where they can conserve energy as well as assess when extra power is needed.

Administrators are using chilled voluntary curtailment to shut chillers down in summer and let the whole system coast, realizing savings during peak demand periods. Administrators have realized labor savings by essentially re-deploying staff in summer by operating boilers only from October 15 to April 15, shutting off boilers that heat.

Tunnels, for example in colder months, operating fewer boilers closer to their full loads. Coal-fired boilers have been converted to natural gas for generating steam, and they buy spot gas through AmerenEnergy using hedging instruments.

Part III: Academic and Research Activities related to the Environment

There are many professors on campus involved in academic and research activities related to the environment. The following information is a brief summary on some of the activities.

The page for Environmental Programs and Studies http://zonvark.wustl.edu/enst/Env.Prgms/ provides information on how students can explore the options available in environmental studies. The College of Arts & Sciences offers courses related to the environment in the departments of Earth & Planetary Sciences, Biology, Anthropology, Economics, and Political Sciences. One can major or minor in Environmental studies through the Earth & Planetary Sciences department. It is an interdisciplinary study and draws upon the fields of anthropology, biology, economics, earth and planetary sciences, political science, environmental regulation, and engineering. One can concentrate on either environmental science or environmental social science.

There is also a freshman-level course, Environmental Science and Policy, that studies issues in environmental science and policy. It is part of the FOCUS program that freshman have the option of applying for. The Hewlett Program in Environmental Studies is a two-year interdisciplinary program in environmental studies. The first year students take a core course and choose other courses from the departments of Earth and Planetary Sciences, Anthropology, Political Science, and Philosophy. The second year students take on independent research projects.

The School of Engineering offers courses in environmental policy and analysis and mitigation of environmental problems. One can major in the Environmental Resources Program, or minor in Environmental Engineering. The Environmental Resources Program is an undergraduate program jointly sponsored by the Department of Civil Engineering and the Department of Engineering and Policy. The program provides training in engineering approaches to environmental protection as well as solutions to environmental problems. Graduates receive a double degree in Civil Engineering and either Engineering Sciences or Engineering and Public Policy.

The minor in Environmental Engineering Science is useful for those interested in careers as environmental scientists, engineers, and analysts. It also provides a foundation for graduate study in environmental engineering and science. There are also research opportunities available for undergraduates and graduates who are interested in the environment. The Jens Environmental Engineering Lab is also in the School of Engineering.

The Center for Air Pollution Impact and Trend Analysis (CAPITA) in the School of Engineering conducts research concerning the air areas of atmospheric aerosols, regional air pollution, and environmental informatics. http://capita.wustl.edu/CAPITA/ The air areas of atmospheric aerosols analysis looks at state-by-state fuel use trends, sulfur and nitrogen emissions. Historical data from numerous sources are also collected on sulfur and nitrogen deposition and airborne concentration. Visibility trends have been compiled for North America and Europe. The CAPITA visibility trend analysis work contributed significantly to the deliberations for the Clean Air Act Amendment of 1990. Environmental informatics deals with the development of data structures for the transmission of environmental knowledge (geographic, animation, hypertext); the use and refinement of interactive, graphic data exploration, and analysis and application and demonstration of multimedia data delivery systems (e.g. Voyager, Movie, Hypertext software).

The School of Law offers an interdisciplinary environmental clinic http://www.wulaw.wustl.edu////Clinics/Intenv/index.html for second and third-year law students as well as undergraduates and graduates in Arts and Sciences and Engineering. Student attorneys and student consultants offer pro bono legal and technical assistance on environmental and community health problems such as lead poisoning, air pollution, water pollution, cleaning up abandoned or contaminated properties, and other concerns affecting urban neighborhoods to individuals and organizations.

The Tyson research center is home to many types of research on animals, plants and the environment. http://www.biology.wustl.edu/tyson/projects.html#research

Of particular interest, Jennifer Eckel of the American Culture Studies Department is researching the effects of the American government bureaucracy on the tasks of repairing government-inflicted environmental damage on public and private grounds.

Diana Bennett, Administrative Officer in the Research Office compiled the following information on Funded Research Activity on Environmental Issues and Research Proposals on Environmental Issues.

Funded Research Activity on Environmental Issues:

Principle Investigator Raymond Arvidson in the Department of Earth and Planetary Sciences is researching the changes associated with the levee break landforms and deposits from the 1993 Missouri River Floods. The effects of erosion, deposition, vegetation and anthropogenic processes on the landforms and deposits will be studied. In a separate study, he is researching the effects the flood had on the engineered portions of the Missouri system, in particular focusing on the sustainability of the wetlands.

Principle Investigator Rudolf Husar in the Department of Mechanical Engineering is analyzing ozone and PM air quality in support of public needs. The goal is to inform and educate the public in a timely manner on the technical and scientific aspects of the ozone/PM problem because informed people can effectively respond to air quality problems and participate in the shaping of Air Quality management policies, regulations and control implementations.

Project Directors Victoria May and Barbara Schaal in the department of Biology are developing a field-ecology program for K-12 teachers. Two one-week “Science of Nature” courses for K-8 teachers will present fundamental concepts of ecology and consider the impact of science on personal and societal issues. A “Field-based Ecology Laboratory” course for high-school science courses will expose teachers to investigative approaches used by research ecologists and provide opportunities to practice ecological methods.

Principle Investigator Jay Turner in the Chemical Engineering department is working on the National Decentralized Water Resources Capacity Development Project. He is assisting in the development of the capacity of electric utilities, water and wastewater utilities, municipalities, engineers, contractors, regulators and other public and private entities to respond to the increasing needs and complexities of decentralized wastewater treatment.

This report looks at what Washington University and other institutions are doing to be environmentally friendly.
