Abstract

Energy Edge is a research-oriented demonstration program involving 28 new commercial buildings in the Pacific Northwest. This paper discusses the energy savings and cost-effectiveness of energy-efficiency measures for the first 12 buildings evaluated using simulation models calibrated with measured end-use data. Average energy savings per building from the simulated code baseline building was 19%, less than the 30% target. The most important factor for the lower savings is that many of the installed measures differ from the measures specified in the design predictions. Only one of the first 12 buildings met the project objective of reducing energy use by more than 30% at a cost below the target of 56 mills/kWh (in 1991 dollars). Based on results from the first 12 calibrated simulation models, 29 of the 66 energy-efficiency measures, or 44%, met the levelized cost criterion. Despite the lower energy savings from individual measures, the energy-use intensities of the buildings are lower than other regional comparison data for new buildings. The authors review factors that contribute to the uncertainty regarding measured savings and suggest methods to improve future evaluations.

Over the energy edge: Results from a seven year new commercial buildings research and demonstration project

Conference Piette, M; Nordman, B; deBuen, O; ...

Edge was a research oriented demonstration project that began in 1985. Twenty-eight commercial buildings were designed and constructed to use 30% less electricity than a hypothetical simulated baseline building. Average savings from the 18 buildings evaluated with post-occupancy, ``tuned`` simulation models were less, at 17%. The cost-effectiveness of the energy-efficiency measures at six of the 18 projects met the target cost-of-conserved (CCE) energy of 5.6cent/kWh for the total package of measures. The most important reason energy savings were not as great as predicted is that the actual, installed energy-efficiency measures and building characteristics changed from the design assumptions.

Energy efficiency standards for residential and commercial equipment: Additional opportunities

Technical Report Rosenquist, Greg; McNeil, Michael; Iyer, Maithili; ...

Energy efficiency standards set minimum levels of energy efficiency that must be met by new products. Depending on the dynamics of the market and the level of the standard, the effect on the market for a given product may be small, moderate, or large. Energy efficiency standards address a number of market failures that exist in the buildings sector. Decisions about efficiency levels often are made by people who will not be responsible for the energy bill, such as landlords or developers of commercial buildings. Many buildings are occupied for their entire lives by very temporary owners or renters, eachmore »« less

Commercial Building Technology Demonstration (Final Scientific/Technical Report)

Technical Report Meirav, Udi

The background for this project was a unique and innovative concept that had been proposed and demonstrated by enVerid Systems, reducing the energy consumption in HVAC systems in commercial and public buildings by up to 50% at peak loads. The concept involves selective scrubbing of gas contaminants from indoor air as a practical substitute for outside air ventilation, the latter being the conventional practice today. This scrubbing enables recycling of most of the indoor air and significantly decreasing the amount of outside air, resulting in a reduced HVAC load and commensurate energy savings for the facility.

DEMONSTRATION OF THE DOE INTERIM ENERGY CONSERVATION STANDARDS FOR NEW FEDERAL RESIDENTIAL BUILDINGS

Technical Report Lee, A.; Baechler, H.; Di Massa, F.; ...

In accordance with federal legislation, the U.S. Department of Energy (DOE) has sponsored a study to demonstrate use of its Interim Energy Conservation Standards for New Federal Residential Buildings. The demonstration study was conducted by DOE and the Pacific Northwest Laboratory (PNL). The demonstration is the second step in a three-step process: I) development of interim standards, 2) demonstration of the interim standards, and 3) development of final standards. The standards are mandatory for federal agency housing procurements. Nevertheless, PNL found at the start of the demonstration that agency use of the interim standards had been minimal.

Bay Area Regional Energy: Network Integrated Commercial Retrofits (BRICR) Project. Final Report

Technical Report Hooper, Barry; Hong, Tianzhen; Long, Nicholas; ...

The BRICR project applied large-scale building energy modeling concepts with the aim of reducing the cost of energy efficiency targeting, design, and project development, and measurement of energy savings for energy efficiency programs implemented by local governments that serve small and medium commercial buildings (SMB). The project leveraged the services and resources of existing local government energy programs serving disadvantaged and hard-to-reach SMB customers. In contrast to programs run by utilities, local government programs generally do not have direct access to energy billing records for an entire class of customers in a geographic area, which prior research demonstrated useful formore »« less
