“…The calculations of energy use and costs can be done with a hand calculator or spreadsheet. Calculations of LCC are done on a personal computer with the publicly available NIST analysis program BLCC (Peterson 1993). The simplicity of this approach is intended to promote additional investigation of the GHP cost-effectiveness under fuel pricing and climate scenarios outside of those considered in this report.…”

PrefaceThe Federal government is the largest single energy consumer in the United States; consumption approaches 1.5 quads/year of energy (1' quad = lo1' Btu) at a cost valued at nearly $10 billion annually. The U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP) supports efforts to reduce energy use and associated expenses in the Federal sector. One such effort, the New Technology Demonstration Program (NTDP), seeks to evaluate new energy-saving U.S. technologies and secure their more timely adoption by the U.S. government.Pacific Northwest Laboratory (PNL)'") is one of four DOE national multiprogram laboratories that participate in the NTDP by providing technical expertise and equipment to evaluate new, energy-saving technologies being studied and evaluated under that program.This two-volume report describes a field evaluation that PNL conducted for DOE/FEMP and the U.S. Department of Defense (DoD) Strategic Environmental Research and Development Program (SERDP) to examine the performance of a candidate energy-saving technology-a gas-engine-driven heat pump. The unit was installed at a single residence at Fort Sam Houston, a U.S. Army base in San Antonio, Texas, and the performance was monitored under the NTDP. Participating in this effort under a Cooperative Research and Development Agreement (CRADA) were York International, the heat pump manufacturer; Gas Research Institute (GRI), the technology developer; City Public Service of San Antonio, the local utility; American Gas Cooling Center (AGCC); Fort Sam Houston; and PNL. The purpose of the Fort Sam Houston/Triathlon demonstration is to evaluate the performance and cost-effectiveness of the Triathlon gas heat pump (GHP) in the Federal sector. This is done by measuring the performance of the candidate unit and comparing it to the measured performance of conventional heating, ventilating, and air-conditioning (HVAC) systems currently in the residences at the base. The energy consumption, thermal measurements, and maintenance records will be primary elements in the life-cycle cost analysis'of potential savings from the candidate unit.The NTDP project at Fort Sam Houston (San Antonio, Texas) features a 3-ton gas-enginedriven heat pump. A single-cylinder, four-stroke, 5-hp engine fueled by natural gas drives the heat pump's compressor. A distinctive feature of the technology is an inherent load-matching capability. The heat pump can vary engine speed and blower fan speed, and thereby . dynamically control capacity to balance with thermal loads. This balance minimizes the need for cycling and reduces the associated thermal losses, fluctuations in room temperature and humidity, and equipment wear. The unit produces added heating capacity and improved supply-air temperatures through engine-waste heat recovery. The Triathlon GHP is manufactured by York International.. Three test houses at the Fort were used for the field comparison of the Triathlon against conventional residential HVAC systems. The houses were chosen to have identical structur...

Nowadays, energy retrofit for existing buildings has become a worldwide approach to reduce total energy consumption. A wide range of energy-efficient retrofit measures is actively affecting the decision process, of which retrofit alternatives should be used. The existing study aims to evaluate the effects of façade retrofit measures in residential buildings in Cairo using life-cycle cost analysis. An extensive variety of façade retrofit alternatives was explored individually and combined. A hypothetical benchmark building was used as a reference to represent typical residential buildings in Cairo. DesignBuilder was adopted to assess and quantify the energy-saving potentials for the proposed measures. The evaluation process was based on a parametric analysis of four major façade parameters that are affecting building energy performance; exterior wall configuration, glazing type, window-to-wall ratio and external shading. Thermal characteristics for façade retrofit measures were analysed to give a better understanding of the thermal performance for each retrofitting case. Results showed that the most cost-effective alternative for façade retrofit is to install a 1 m overhang as an external shading device, which reached 1.4% life-cycle cost saving and 18% energy saving. Finally, a sensitivity analysis for the main life-cycle cost supplements was presented to show major variables that are affecting life-cycle cost analysis.

“…Life-cycle costs of the five EROs evaluated above are summarized in Table 5 .1. The NPV s and SIRs were computed using BLCC (building life-cycle cost) version 3.2 for 1993 (Petersen 1992;Ruegg and Petersen 1987;NBS 1987;NIST 1993). There are some interactions that will reduce the attractiveness of some EROs and increase the attractiveness of others.…”

The goal of the U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP) is to facilitate energy-efficiency improvements at federal facilities. This is accomplished by a balanced program of technology development, facility assessment, and use of cost-sharing procurement mechanisms. Technology development focuses on the tools, software, and procedures used to identify and evaluate efficiency technologies and improvements. For facility assessment, FEMP provides metering equipment and trained analysts to federal agencies exhibiting a commitment to improve energy-use efficiency. To assist in procurement of energy-efficiency measures, FEMP helps federal agencies devise and implement performance contracting and utility demand-side management strategies.Pacific Northwest Laboratory (PNL)<•> supports the FEMP mission. The Laboratory and its contractors work with federal facility energy managers to assess and implement energy-efficiency improvements at federal facilities nationwide.The capabilities of the Mobile Energy Laboratory (MEL) provide onsite measurement and evaluation of energy conversion, distribution, and end-use efficiency at federal facilities. The results may be used to justify changes in operating procedures, maintenance efforts, system designs, or energy-using equipment. The MEL capabilities can subsequently be used to assess the results of energy-efficiency projects.
