The overall success of EPAs energy conservation program depends in part on how well EPA facilities are kept informed about the benefits, opportunities, and successes of energy-related activities. To facilitate this communication, EPA has established several communication techniques, including educational outreach resources, site visits to identify energy-savings opportunities, energy consumption tracking, cost reporting, training, and information available through EPAs intranet and the Internet.
An excellent means of conveying a wide variety of information in a concise, easy-to-understand manner is through awareness posters. This year a series of energy awareness posters was developed to highlight energy consumption, illustrate the benefits of installing energy-efficient HVAC systems, explain how innovative HVAC technologies work, describe energy savings performance contracts, and show pollution prevention trends at EPA facilities. These posters were displayed at the annual Buildings and Facilities conference, and were found to be so useful that EPAs Headquarters in Washington, DC and its Region VIII office in Denver, CO, requested copies to display.
"You Have the Power" Campaign
Through this DOE-sponsored campaign, initiated to increase the level of energy conservation awareness throughout the federal government, EPA identified and awarded seven EPA employees for being energy champions. Criteria for selection was based on an individuals effort and success of striving to conserve energy through building design and operation, real estate transactions, and overall promotion of energy conservation awareness. Several promotional materials were developed for the campaign, including energy champion posters that highlighted the selected EPA individuals and the specific work that awarded them with their recognition; "Hometown Hero" newspaper articles describing the efforts that awarded the energy champions with their recognition; a large banner reading "You Have the Power," displayed at EPA Headquarters in Washington, DC, for a month beginning on Earth Day, April 1997; and an industry partnership advertisement to be issued upon award of the NVFEL ESPC. For more information, visit the "You Have The Power" Campaign website.
EPA continues to produce and distribute its quarterly newsletter, Conservation News, as a means to educate a broad Agency audience about energy conservation and pollution prevention. The newsletter serves as the key mechanism for information transfer between EPA Headquarters, the facilities, and the public on topics including energy and water conservation activities, innovative technologies, facility highlights, financing mechanisms, pollution prevention opportunities, program progress, regulatory changes, upcoming events, and training opportunities. These articles provide facility managers with the basis to implement a campaign to conserve energy and at the same time inform the general public about Agency-specific conservation activities. Some of the energy-related articles that were published in FY97 featured:
- The active daylighting system at NVFEL
- NVFELs new equipment purchased with money saved through energy conservation
- Laboratories for the 21st Century
- Energy upgrades at Kerr Laboratory, Ada, Oklahoma.
The expanded use of the Internet offers EPA access to limitless opportunities to inform facilities, staff, and other interested parties of its energy conservation and pollution prevention efforts. EPA has established a strong Internet presence through the continued development of its website. The Office of Administration contributes to EPAs Internet presence through its own website, located at http://www.epa.gov/oaintrnt. OAs website provides instant access to the latest edition of the Conservation News and other noteworthy information relating to EPAs energy conservation efforts.
Conservation Information Clearinghouse and Hotline
FMSD established the Clearinghouse and Hotline to serve as a focal point for collecting and disseminating information about energy and water conservation. The Clearinghouse also maintains a library of information, available to engineers, architects, and others, on such topics as energy conservation, energy-efficient technologies, CFC management, and pollution prevention. The Hotline is available for employees to access the clearinghouse information, and to question or comment on conservation-related activities. For example, during FY97, an employee suggested that EPA continue using existing chillers and replace the CFC-containing refrigerant, rather than replace the entire chiller. After Hotline staff researched the suggestion, the response stated that, although a refrigerant retrofit may have a positive net present value over the lifespan of the chillers compared to the replacement option, the environmental effect would be negative.
As part of the conservation program, EPA distributes a package of energy and water conservation awareness information annually (in October) to all facility and energy managers. In FY97, EPA distributed an awareness package designed to directly address the information needs of facility managers and communicate useful information in an accessible fashion. This years package included:
- A computer spreadsheet to track energy consumption, automatically develop quarterly consumption reports, graph energy usage, and calculate associated pollution generated
- Tips to conserve energy on a daily basis
- Computer screen savers to encourage energy conservation
- Posters with energy conservation-related facts that employees can do to save energy.
EPA visited six of its laboratories in FY97 to assess and monitor existing energy-intensive mechanical equipment and energy management practices, evaluate conservation opportunities, and provide recommendations to help facilities meet their energy reduction goals. Through these visits, EPA again confirmed that HVAC systems are the largest energy conservation opportunity for the Agency due to the health and safety requirements for one-pass air. As a result, its energy conservation program continues to focus on the HVAC challenge as the principal target for energy reduction. In addition, the visits have produced elevated awareness and commitment to energy reduction. The following site visits and activities conducted in FY97 are listed below.
At the Ada facility, EPA:
- Developed a strategic comprehensive energy monitoring plan to eventually determine the facilitys energy baseline
- Installed monitoring equipment and microdataloggers, and conducted an energy audit
- Monitored facility occupancy and lighting use using occupancy sensor dataloggers for a five week period
- Organized an ESPC team and began the process of developing an RFP for a comprehensive facility upgrade to be financed through the ESPC
- Conducted a technical analysis of a ground source heat pump application. The results encouraged the option of performing an integrated facility upgrade.
Ann Arbor, MI
At the NFVEL, EPA:
- Provided technical assistance in the development of laboratory operating parameters
- Modified the data deck for the DOE-2 simulation to more accurately represent the internal test load of the laboratory, therefore provide a better understanding of the energy consumed.
At the Andrew W. Breidenbach Environmental Research Center (AWBERC), EPA:
- Conducted a follow-up assessment of the opportunities at the facility and discussed a potential demonstration project, including heat pipe and indirect evaporative cooling technologies
- Prepared a report including detailed information on the energy required to provide given relative humidity levels, technologies commercially available for dehumidification and a case study of AWBERCs humidity levels verses its energy consumption
- Conducted research and prepared information on the rules governing discharge of non-contact cooling water in Ohio. AWBERC uses potable water for heat transfer and then discharges to the sewer.
At the Edison facility, EPA:
- Conducted an assessment of the operation of an existing desiccant dehumidification system
- Provided recommendations for the use of a solar hot water system.
Gulf Breeze, FL
At the Gulf Breeze facility, EPA:
- Installed monitoring equipment in the air handling unit in Building 49. The data gathered from the monitoring was the foundation of a technical report entitled, "Heat Pipe Effectiveness Study, Gulf Breeze Laboratory Installation Pensacola, Florida." The report determined the level of dehumidification and avoided energy costs performed by the heat pipe that was installed in September 1996
- Conducted several technical reviews of drawings for the NDDC application and corrected technical inaccuracies. Project was bid and awarded, and will be installed in FY98.
- Linked the air conditioning system of a newly renovated building on-site to an oversized chiller in an adjacent building. This saved renovation costs and energy consumption for both buildings.
At the Narragansett facility, EPA:
- Conducted a comprehensive energy audit, including interviewing laboratory personnel and gathering facility data (temperature, occupancy, air flow, lighting). Staff discussed strategy for measuring air changes, room differential pressure and waste air, and water streams
- Conducted the second phase of a comprehensive energy audit. The main objective was to install monitoring equipment to obtain data necessary to calculate the coefficient of performance, a quantification of the facilitys baseline energy status
- Conducted a technical analysis of a geothermal source heat pump application as the foundation of a comprehensive energy upgrade. The results encouraged the option of performing an integrated facility upgrade. An ESPC is being pursued to obtain the upgrade.
The energy audits at Ada and Narragansett helped determine the opportunity for energy savings, and initiated the development of the DOE-2 model simulations to determine the feasibility for conducting an energy upgrade. For both laboratories, ground source and geothermal technology are being considered for incorporation.
Site visits to Gulf Breeze and Edison were conducted to determine the effectiveness of existing equipment. For the Gulf Breeze laboratory, analyses of temperature and humidity data, along with a weather bin analysis provided the basis for a heat pipe effectiveness study. Through the study, it was determined that the heat pipe pre-cooling load, and subsequent reheat load, increases linearly with outside temperature and that the heat pipe provides a maximum of 20-tons of pre-cooling and 240 kBTU/h of reheat without energy input. At the Edison laboratory, a technical evaluation of the existing desiccant system was conducted. The site visit to the Cincinnati laboratory was primarily a follow-up to encourage energy savings opportunities identified during several energy audits conducted the previous year.
In FY98 EPA anticipates visiting the following laboratories to assess the energy savings opportunities: Ada, OK; Ann Arbor, MI; Athens, GA; Duluth, MN; Edison, NJ; Gulf Breeze, FL; Manchester, WA; Narragansett, RI; Richmond, CA.
The Energy Policy Act requires that each federal agency track its energy and water consumption information. In response, EPA developed a report form to be completed by each facilitys energy manager on a quarterly basis (Appendix A, Figure 1, provides a copy of the form). The quarterly report includes consumption and cost information for all forms of energy, including electricity, natural gas, propane, fuel oil, and purchased steam, as well as square footage information. This reporting process began in 1993, and continues for the 16 facilities where EPA is directly responsible for paying utilities.
EPAs energy consumption database shows that the Agencys utility-responsible facilities consumed the following energy in FY97:
- 128.4 million kilowatt hours (kWh) of electricity
- 5.0 million cubic-feet of natural gas
- 183,670 gallons (gals) of fuel oil
- 6,530 gals of propane
- 33.8 million pounds (lbs) of purchased steam.
|BTU Conversion Factors|
Annual energy consumption at each facility is summarized in British Thermal Units (Btu). With approximately 2.9 million square feet of space, EPA consumed 354,903 Btu per square-foot during FY97 (since Montgomerys FY97 consumption was not verified, their energy consumption from FY96 was used for FY97). Appendix A provides the Agencys FY97 Annual Energy Management Data Report.
Since 1995, through its efforts to reduce energy consumption, EPA has eliminated the production of approximately 4,329 tons of carbon dioxide emissions associated with energy production. This CO2 emission reduction has the equivalent effect of planting 1,674 acres of trees or removing 808 cars from the road.
|EPA's FY97 electricity reduction measures saved over 24 million kW=hours of electricity compared to 1985 levels! This reduction, in turn, prevented 18,100 tons of utility- generated carbon dioxide in FY97, equivalent to removing 2,410 cars from the road.|
During the past four years, EPA has required its facilities to monitor and report water consumption and costs on a quarterly basis (these data are obtained in conjunction with the energy consumption data). Since 1994, EPA has required the use of water conserving equipment in all newly leased and built facilities. Assessments of water conservation opportunities are part of EPAs facility site visit program and have led to operational and management measures that have reduced water consumption. Compared to the 1994 baseline, in FY97 EPA reduced water consumption by 16 percent. (See Appendix A, Figure 5 for EPAs Annual Water Consumption.)
EPA participated in, and hosted, numerous training events during FY97. Program staff regularly attended energy and water conservation conferences, seminars, and working groups. Titles of these events include: the Pre-Bid Conference for the ESPC Project at National Vehicle Fuel Emissions Laboratory, Ann Arbor, Michigan; the National Renewable Energy Training Conference; ESPC Training; the Federal Energy Management Program Renewable Working Group; Water Conservation Working Group; and the Corporation for Solar and Renewable Resources Conference. Product demonstration seminars and trips with various vendors were arranged for EPA's engineers, architects and facility management to encourage their use of proven innovative technologies. In addition, contract staff who are certified trained energy managers briefed program staff periodically throughout the year on innovative technologies and technology design.
From now through FY99, many of EPAs engineers, facility managers, and energy managers will have attended the Association of Energy Engineers Certification for Energy Mangers (CEM) training program (offered nationwide) and become Certified Energy Mangers.
Energy Management Training
The Office of Administration, in cooperation with Lawrence Berkley National Laboratory (LBL) and the National Renewable Energy Laboratory (NREL), has instituted a semi-annual conference entitled "Laboratories for the 21st Century" for agencies pursuing energy upgrades in federal laboratories. EPA and DOE partnered on this program due to the energy-intensive nature of laboratories, the need to provide sound, energy-efficient technology alternatives for laboratory applications, and to create a forum for federal laboratories to obtain up-to-date information and support for implementing energy conservation programs.
The first conference was held at the American Institute of Architects headquarters in Washington, DC, in September 1997 and was well attended with representatives from a wide variety of agencies, including the National Institutes of Health, the Center for Disease Control, Sandia National Laboratory, and Princeton Plasma Research Laboratory. The conference is organized into two sessions, a formal training component and an informal open discussion. The training is provided by a host of speakers from EPA, DOE, LBL, NREL, and academia, who present views and technical information on subjects as varied as utility deregulation and passive solar design and the related impacts and considerations for laboratory design, construction, and operation. The informal sessions enabled attendees to present their agencys current issues and projects and have their federal peers join in an exchange of views and experiences. The second conference is scheduled for May 5-7, 1998, in San Francisco, California.
Office of Administrations Annual National Conference
EPA hosted its Office of Administrations Annual National Conference to provide training to EPA employees responsible for facility maintenance, operations, and safety. Sessions on energy and water conservation, pollution prevention, and environmental regulatory compliance were presented to facility representatives. EPA staff learned how to incorporate these programs into the B&F funding process.
The session of energy conservation focused on current efforts to implement ESPCs at several EPA facilities in addition to the following topics: EPAs mission and national goals of security, sustainability, environmental choices, pollution prevention and the future; personal ownership for facility managers and employees; energy flows within the laboratory environment; and integration of energy-efficient technologies to provide a comprehensive energy system.
