Download or read book Electrical Energy and Demand Savings from a Geothermal Heat Pump Energy Savings Performance Contract at Ft Polk LA written by and published by . This book was released on 1997 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: At Fort Polk, LA the space conditioning systems of an entire city (4,003 military family housing units) have been converted to geothermal heat pumps (GHP) under an energy savings performance contract. At the same time, other efficiency measures such as compact fluorescent lights (CFLs), low-flow hot water outlets, and attic insulation were installed. Pre- and post-retrofit data were taken at 15-minute intervals on energy flows through the electrical distribution feeders that serve the family housing areas of the post. 15-minute interval data was also taken on energy use from a sample of the residences. This paper summarizes the electrical energy and demand savings observed in this data. Analysis of feeder-level data shows that for a typical year, the project will result in a 25.6 million kWh savings in electrical energy use, or 32.4% of the pre-retrofit electrical consumption in family housing. Results from analysis of building-level data compare well with this figure. Analysis of feeder-level data also shows that the project has resulted in a reduction of peak electrical demand of 6,541 kW, which is 39.6% of the pre-retrofit peak electrical demand. In addition to these electrical savings, the facility is also saving an estimated 260,000 therms per year of natural gas. It should be noted that the energy savings presented in this document are the apparent energy savings observed in the monitored data, and are not to be confused with the contracted energy savings used as the basis for payments. To determine the contracted energy savings, the apparent energy savings may require adjustments for such things as changes in indoor temperature performance criteria, additions of ceiling fans, and other factors.

Available in PDF, EPUB and Kindle. Book excerpt: At Fort Polk, LA the space conditioning systems of 4,003 military family housing units have been converted to geothermal heat pumps (GHP) under an energy savings performance contract (ESPC). At the same time, other efficiency measures, such as compact fluorescent lights (CFLs), low-flow shower heads, and attic insulation, were installed. An independent evaluation of the Fort Polk ESPC was carried out. Findings indicate that the project has resulted in a 25.6 million kWh savings in electrical energy use, or 32.4% of the pre-retrofit electrical consumption in family housing, for a typical meteorological year. Peak electrical demand has also been reduced by 6,541 kW, which is 39.6% of the pre-retrofit peak demand. Natural gas savings are about 260,000 therms per year. In addition, the ESPC has allowed the Army to effectively cap its future expenditures for family housing HVAC maintenance at about 77% of its previous costs. Given these successful results, the Fort Polk ESPC can provide a model for other ESPCs in both the public and the private sectors. The purpose of this paper is to outline the method by which the ESPC was engineered and implemented, both from the standpoint of the facility owner (the US Army) and the energy services company (ESCO) which is carrying out the contract. The lessons learned from this experience should be useful to other owners, ESCOs and investors in the implementation of future ESPCs. It should be noted that the energy savings presented in this document are the apparent energy savings observed in the monitored data, and are not to be confused with the contracted energy savings used as the basis for payments. To determine the contracted energy savings, the apparent energy savings may require adjustments for such things as changes in indoor temperature performance criteria, additions of ceiling fans, and other factors.

Available in PDF, EPUB and Kindle. Book excerpt: The US Army, in cooperation with an energy services company (ESCO), used private capital to retrofit 4,003 family housing units on the Fort Polk, Louisiana, military base with geothermal heat pumps (GHPs). The project was performed under an energy savings performance contract (ESPC) that provides for the Army and the ESCO to share the cost savings realized through the energy retrofit over the 20-year life of the contract. Under the terms of the contract, the ESCO is responsible for maintaining the GHPs and provides ongoing measurement and verification (M and V) to assure cost and energy savings to the Army. An independent evaluation conducted by the Department of Energy's Oak Ridge National Laboratory indicates that the GHP systems in combination with other energy retrofit measures have reduced annual whole-community electrical consumption by 33%, and natural gas consumption by 100%. These energy savings correspond to an estimated reduction in CO2 emissions of 22,400 tons per year. Peak electrical demand has been reduced by 43%. The electrical energy and demand savings correspond to an improvement in the whole-community annual electric load factor from 0.52 to 0.62. As a result of the project, Fort Polk saves about $450,000 annually and benefits from complete renewal of the major energy consuming systems in family housing and maintenance of those systems for 20 years. Given the magnitude of the project, the cost and energy savings achieved, and the lessons learned during its design and implementation, the Fort Polk ESPC can provide a model for other housing-related energy savings performance contracts in both the public and private sectors.

Download or read book Low risk and Cost effective Prior Savings Estimates for Large scale Energy Conservation Projects in Housing written by and published by . This book was released on 1997 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many opportunities exist for large-scale energy conservation projects in housing. Energy savings performance contracting (ESPC) is now receiving greater attention, as a means to implement such projects. This paper proposes an improved method for prior (to construction) savings estimates for these projects. The proposed approach to prior estimates is verified against data from Fort Polk, LA. In the course of evaluating the ESPC at Fort Polk, the authors have collected energy use data which allowed them to develop calibrated engineering models which accurately predict pre-retrofit energy consumption. They believe that such calibrated models could be used to provide much more accurate estimates of energy savings in retrofit projects. The improved savings estimating approach described here is based on an engineering model calibrated to field-collected data from the pre-retrofit period. A dynamic model of pre-retrofit energy use was developed for all housing and non-housing loads on a complete electrical feeder at Fort Polk. The model included the heat transfer characteristics of the buildings, the pre-retrofit air source heat pump, a hot water consumption model and a profile for electrical use by lights and other appliances. Energy consumption for all 200 apartments was totaled, and by adjusting thermostat setpoints and outdoor air infiltration parameters, the models were matched to field-collected energy consumption data for the entire feeder. The energy conservation measures were then implemented in the calibrated model: the air source heat pumps were replaced by geothermal heat pumps with desuperheaters; hot water loads were reduced to account for the low-flow shower heads; and lighting loads were reduced to account for fixture delamping and replacement with compact fluorescent lights. The analysis of pre- and post-retrofit data indicates that the retrofits have saved 30.3% of pre-retrofit electrical energy consumption on the feeder modeled in this paper.

Download or read book Super Energy Savings Performance Contracts written by and published by . This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This four-page publication describes the U.S. Department of Energy's (DOE's) streamlined energy savings performance contracting, or ''Super ESPC, '' process, which is managed by DOE's Federal Energy Management Program (FEMP). Under a Super ESPC, a qualifying energy service company (ESCO) from the private sector pays for energy efficiency improvements or advanced renewable energy technologies (e.g., photovoltaic systems, wind turbines, or geothermal heat pumps, among others) for a facility of a government agency. The ESCO is then repaid over time from the agency's resulting energy cost savings. Delivery orders under these contracts specify the level of performance (energy savings) and the repayment schedule; the contract term can be up to 25 years, although many Super ESPCs are for about 10 years or less.

Book excerpt: Constrained budgets and increasing energy efficiency goals have led federal agencies to explore innovative ways to fund energy improvements, including the Department of Energy's Energy Savings Performance Contracts (ESPC). An expected increase in the use of ESPCs has raised questions about agencies' ability to ensure that the government's interests are protected. ESPCs can span up to 25 years and be valued at millions of dollars each. This book examines the extent to which agencies have used ESPCs and plan to use them; projects have achieved their expected cost and energy savings; and agencies have overseen and evaluated such projects.

Available in PDF, EPUB and Kindle. Book excerpt: An energy savings performance contract energy sales agreement (ESPC ESA) is a project structure, similar to a power purchase agreement, that uses the multiyear ESPC authority to implement renewable energy projects (referred to as ESA energy conservation measures [ECMs]) on federal buildings or land. The ESA ECM is initially privately owned for tax-incentive purposes, and the federal agency purchases the electricity it produces. An ESPC ESA is one of the most cost-effective methods for implementing on-site distributed energy projects at civilian federal agency sites.
