Des Moines Energy Conservation Project
General Services Administration
Des Moines, Iowa
The General Services Administration's (GSA) Des Moines team maximized energy-saving opportunities by using a "whole building approach" to energy reduction at the Des Moines Federal Building. Using Super ESPC financing, the team implemented several different projects at the site. The measures completed under the $1.4 million project include replacement of the entire steam boiler plant, conversion of multi-zone air handling systems to variable air volume flow, removal and replacement of steam traps, installation of water-conserving fixtures, and securing rate reduction for natural gas. The project also included installation of vending machine controllers. The controllers project served a double purpose-as an energy saving measure as well as a "pilot project"-a model that can be duplicated in other GSA facilities in the Heartland Region. Because of the various measures taken, the facility's energy consumption is guaranteed to be reduced by 6.5 billion Btu annually, with cost savings of $67,000.

The Internal Revenue Service's area-wide shared services group obtained ESPC financing to complete numerous upgrades at the Austin Service Center, resulting in dramatic energy savings for the facility. The group tackled three major areas of energy use for the facility: electricity for air conditioning, electricity for lighting, and water use. For the chilled water system, installation of a new chiller, along with other measures, created a highly efficient and reliable system to serve the entire facility. The group also completed replacement and retrofits of lighting fixtures, lamps, and ballasts. Water conservation markedly improved through the installation of high efficiency fixtures which use less than half of the water as do the old fixtures. Through the efforts of the group, the facility has achieved annual energy savings of more than 20 billion Btu, 2.1 million gallons of water, and cost savings of $310,000 per year.
By combining agency-funded work and utility-financed work into a single project, the Varick Street Building Modernization Group accomplished a variety of overdue measures at the facility. The building faced imminent replacement of its chillers (which used CFC refrigerant), and needed other energy-saving upgrades. Through the use of a GSA area-wide utility contract, the group combined both the chiller replacement (an agency-funded project) and utility-financed measures in one contract. The other energy-saving measures included a new energy management control system; variable frequency drives and energy-efficient motors; and energy-efficient lights. The group expects annual savings of more than $431,000, and energy savings of more than 14.8 billion Btu as a result of the steps taken. The cost savings will allow payback of the total project cost, including interest, in less than 10 years. By integrating the funded and financed work into one project, the GSA team demonstrated that agencies do not have to defer energy conservation or facility upgrade work because of a lack of full funding. In fact, the financing strategy taken at the facility has already appeared in two other GSA locations and has become an option considered frequently at GSA facilities.

Beaufort Housing Geothermal Heat Pump Project
United States Marine Corps
Beaufort, South Carolina
During FY 2001, Marine Corps Air Station Beaufort, home to seven Marine and two Navy F/A-18 fighter squadrons, entered into a basic ordering agreement with a local utility company to replace old HVAC and hot water generating equipment with geothermal heat pump systems that provide heating, cooling and domestic hot water. The geothermal upgrade took place in 1,236 of the 1,276 military family housing units on the base. Installation of this $11.5 million utility energy service contract project cut energy use by 25 percent in family housing. During FY 2001 the project saved more than $52,000 and almost 5 billion Btu. FY 2002 energy reductions are estimated to exceed 40 percent.
Members of the 434th Air Refueling Wing at Grissom Air Reserve Base have made top-flight progress in implementing the policy and directives of Executive Order 13123 during FY 2001. The outstanding performance of the 434th Air Refueling Wing in energy efficiency showed in the 56 percent reduction in energy use from FY 2000 to FY 2001, and an overall reduction of 64 percent since FY 1985. The successful completion of an ESPC project, through effective planning and preparation by Base engineers, and the negotiation, award, and administration by Base contracting, resulted in improvements that will continue to pay significant dividends long into the future. The project installed energy-efficient lighting and heating equipment, affecting virtually all Base buildings. It was the vehicle by which Grissom's outdated and inefficient central heating plant could be permanently removed from service. Total cost and energy saved during FY 2001 was more than $1 million and 168 billion Btu.
