An analysis of predicted vs monitored space heat energy use in 83 homes. Residential Construction Demonstration Project

Description: In 1983 the Northwest Power Planning Council (NWPPC) directed the Bonneville Power Administration to create the Residential Standards Demonstration Program to demonstrate actual construction using the Model Conservation Standards (MCS) and to collect cost and thermal data in residential structures. Much information was gained from that program, and as a consequence, the MCS were reevaluated and updated. A second program, the Residential Construction Demonstration Project was created to further investigate residential energy efficiency measures for both cost and thermal performance. The Residential Construction Demonstration Project was administered by the Washington State Energy Office in conjunction with the Idaho Department of Water Resources, the Montana Department of Natural Resources and Conservation, and the Oregon Department of Energy. This analysis is based upon information collected during the first phase of the Residential Construction Demonstration Project (RCDP).

Savings from new oil furnaces: A study conducted as part of Washington State`s Oil Help Program

Description: The Washington State Energy Office (WSEO) has been running the Oil Help program for three years. Originally operated as a loan program, Oil Help switched to rebates during the 1987 and 1988. Rebates for oil furnace replacements made up over 70 percent of rebate funds, which totaled about $1.3 million. WSEO Evaluation started research in summer of 1988, with the goal of including 100 new furnace households (with a control group of similar size) in the study. Our intention was to look at long-term oil consumption comparing each household with itself over the two periods. The final study group consists of 43 households and a control group of 87 households. The report begins with a review of related research. A discussion of research methodology, weather normalization procedure, data attrition, and important descriptive details follows. Changes in consumption for the new furnace and control groups are reported and are tested for significance. Finally, we discuss the implications of the results for the cost effectiveness of an oil furnace replacement.

1990 Washington State directory of biomass energy facilities

Description: This second edition is an update of biomass energy production and use in Washington State for 1989. The purpose of this directory is to provide a listing of known biomass users within the state and some basic information about their facilities. The data can be helpful to persons or organizations considering the use of biomass fuels. The directory is divided into three sections of biomass facilities with each section containing a map of locations and a data summary table. In addition, a conversion table, a glossary and an index are provided in the back of the directory. The first section deals with biogas production from wastewater treatment plants. The second section provides information on the wood combustion facilities in the state. This section is subdivided into two categories. The first is for facilities connected with the forest products industries. The second category include other facilities using wood for energy. The third section is composed of three different types of biomass facilities -- ethanol, municipal solid waste, and solid fuel processing. Biomass facilities included in this directory produce over 64 trillion Btu (British thermal units) per year. Wood combustion facilities account for 91 percent of the total. Biogas and ethanol facilities each produce close to 800 billion Btu per year, MSW facilities produce 1845 billion BTU, and solid fuel processing facilities produce 2321 billion Btu per year. To put these numbers in perspective, Washington`s industrial section uses 200 trillion Btu of fuels per year. Therefore, biomass fuels used and/or produced by facilities listed in this directory account for nearly 32 percent of the state`s total industrial fuel demand. This is a sizable contribution to the state`s energy needs.

GEODIM, Version 2.1: Users manual (English units version)

Description: The GEODIM computer program has been developed as a joint project of the University of Lund, Lund, Sweden and the Washington State Energy Office (WSEO). The development of GEODIM was originally begun in response to the need to optimize the Lund, Sweden geothermal system. This system is the world`s largest heat pump geothermal system having an output of 50MW thermal. The 50MW of output provides a significant percentage of the base load thermal demand of the Lund district heating system. When approached by WSEO, the University of Lund agreed to expand the capability of the program and make it equally usable for the optimization of direct use system`s which do not employ heat pumps. In addition, the university prepared examples of how the program can be used. The program has been extensively tested against data from the Lund system which now has five years of operating data. The program has proved itself to be a valuable tool for optimizing piping systems and system operation. Although the program was originally designed for the optimization of geothermal systems employing both production and injection wells, it can be just as successfully used for any system using a water source, be it surface water or waste water from industry or effluent from a sewage treatment plant.

Mixed waste paper to ethanol fuel. A technology, market, and economic assessment for Washington

Description: The objectives of this study were to evaluate the use of mixed waste paper for the production of ethanol fuels and to review the available conversion technologies, and assess developmental status, current and future cost of production and economics, and the market potential. This report is based on the results of literature reviews, telephone conversations, and interviews. Mixed waste paper samples from residential and commercial recycling programs and pulp mill sludge provided by Weyerhauser were analyzed to determine the potential ethanol yields. The markets for ethanol fuel and the economics of converting paper into ethanol were investigated.

Cost-effectiveness of compact fluorescent lighting. Retrofits for residential consumers in the Pacific Northwest

Description: Compact fluorescent technologies have been steadily improving. There has been increased interest in utilizing compact fluorescents to provide cost-effective energy savings for electric utilities in the residential sector. Several utilities in the United States have already distributed compact fluorescents to consumers free of charge. This study assesses the cost-effectiveness of compact fluorescents from the perspectives of consumers and utilities in the Pacific Northwest, where electricity rates are, on average, the lowest in the United States. The study also assesses cost-effectiveness from a societal perspective. Secondary hearing impacts and the value of reduced emissions of pollutants are incorporated into the analysis. Results indicate that compact fluorescents are more likely to be cost-effective as the perspective upon which they are assessed is broadened. Thus, they are least likely to be viewed as cost-effective by consumers, more likely to be considered cost-effective from a utility perspective, and almost always cost-effective from a societal perspective. Given these differences, is is suggested that policies be developed to capture the societal benefits of compact fluorescent retrofits through alternative regulatory or market mechanisms.

Air-leakage control manual

Description: This manual is for builders and designers who are interested in building energy-efficient homes. The purpose of the manual is to provide the ``how and why`` of controlling air leakage by means of a system called the ``Simple Caulk and Seal`` (SIMPLE{center_dot}CS) system. This manual provides an overview of the purpose and contents of the manual; It discusses the forces that affect air leakage in homes and the benefits of controlling air leakage. Also discussed are two earlier approaches for controlling air leakage and the problems with these approaches. It describes the SIMPLE-{center_dot}CS system. It outlines the standard components of the building envelope that require sealing and provides guidelines for sealing them. It outlines a step-by-step procedure for analyzing and planning the sealing effort. The procedure includes (1) identifying areas to be sealed, (2) determining the most effective and convenient stage of construction in which to do the sealing, and (3) designating the appropriate crew member or trade to be responsible for the sealing.

An Analysis of Predicted vs. Monitored Space Heat Energy Use in 120 Homes :Residential Construction Demonstration Project Cycle II.

Description: The SUNDAY thermal simulation program was used to predict space heat energy consumption for 120 energy efficient homes. The predicted data were found to explain 43.8 percent of the variation in monitored space heat consumption. Using a paired Student`s to test, no statistically significant difference could be found between mean predicted space heat and monitored space heat for the entire sample of homes. The homes were grouped into seven classes, sub-samples by total heat loss coefficient. An intermediate class (UA = 300--350 Btu/{degrees}F) was found to significantly over-predict space heat by 25 percent. The same class was over-predicted by 16 percent in the analogous Cycle 1 research, but the sample size was smaller and this was not found to be statistically significant. Several variables that were not directly included as inputs to the simulation were examined with an analysis of covariance model for their ability to improve the simulation`s prediction of space heat. The variables having the greatest effect were conditioned floor area, heating system type, and foundation type. The model was able to increase the coefficient of determination from 0.438 to 0.670; a 54 percent increase. While the SUNDAY simulation program to aggregate is able to predict space heat consumption, it should be noted that there is a considerable amount of variation in both the monitored space heat consumption and the SUNDAY predictions. The ability of the program to accurately model an individual house will be constrained by both the quality of input variables and the range of occupant behavior. These constraints apply to any building model.

Residential construction demonstration project, Cycle II: Active ventilation

Description: This report documents the analysis of the performance of natural and mechanical ventilation in Pacific Northwest homes. The analysis was part of Cycle II of the Residential Construction Demonstration Project, sponsored by Bonneville Power Administration (BPA). Since 1986, the Residential Construction Demonstration Project (RCDP) has sponsored the collection of data on energy efficient homes in the Pacific Northwest that comply with these new standards and requirements. Cycle II of RCDP was conducted between September 1987 and April 1990. It concentrated on energy innovations in homes built to the Super Good Cents specification. All of the test homes have electric heat and mechanical ventilation systems. Seven different types of active ventilation systems are represented in the homes. Three of these system types are equipped with heat recovery devices, and are represented in approximately a quarter of the test homes. The potential for both natural and mechanical ventilation was measured. Potential structural leakage was measured by blower door testing. Flow rate and operating time of mechanical ventilation systems were measured with flow hoods and hour meters. Actual ventilation was measured by using a passive tracer gas technique for several weeks during the heating season and at times of normal occupancy.

Cogeneration : A Regulatory Guide to Leasing, Permitting, and Licensing in Idaho, Montana, Oregon, and Washington.

Description: This guidebook focuses on cogeneration development. It is one of a series of four guidebooks recently prepared to introduce the energy developer to the federal, state and local agencies that regulate energy facilities in Idaho, Montana, Oregon, and Washington (the Bonneville Power Administration Service Territory). It was prepared specifically to help cogeneration developers obtain the permits, licenses and approvals necessary to construct and operate a cogeneration facility. The regulations, agencies and policies described herein are subject to change. Changes are likely to occur whenever energy or a project becomes a political issue, a state legislature meets, a preexisting popular or valuable land use is thought threatened, elected and appointed officials change, and new directions are imposed on states and local governments by the federal government. Accordingly, cogeneration developers should verify and continuously monitor the status of laws and rules that might affect their plans. Developers are cautioned that the regulations described herein may only be a starting point on the road to obtaining all the necessary permits.
