  • In order to meet whole-house energy savings targets beyond 50% in residential buildings, it will be essential that new technologies and systems approaches be developed to address miscellaneous electric loads (MELs). These MELs are comprised of the small and diverse collection of energy-consuming devices found in homes, including what are commonly known as plug loads (televisions, stereos, microwaves), along with all hard-wired loads that do not fit into other major end-use categories (doorbells, security systems, garage door openers). MELs present special challenges because their purchase and operation are largely under the control of the occupants. If no steps are takenmore » to address MELs, they can constitute 40-50% of the remaining source energy use in homes that achieve 60-70% whole-house energy savings, and this percentage is likely to increase in the future as home electronics become even more sophisticated and their use becomes more widespread. Building America (BA), a U.S. Department of Energy research program that targets 50% energy savings by 2015 and 90% savings by 2025, has begun to identify and develop advanced solutions that can reduce MELs.« less
  • To track progress toward aggressive multi-year whole-house energy savings goals of 40-70% and onsite power production of up to 30%, the U.S. Department of Energy (DOE) Residential Buildings Program and the National Renewable Energy Laboratory (NREL) developed the Building America Research Benchmark in 2003. The Benchmark is generally consistent with mid-1990s standard practice, as reflected in the Home Energy Rating System (HERS) Technical Guidelines, with additional definitions that allow the analyst to evaluate all residential end-uses, an extension of the traditional HERS rating approach that focuses on space conditioning and hot water. A series of user profiles, intended to representmore » the behavior of a''standard'' set of occupants, was created for use in conjunction with the Benchmark. Finally, a set of tools was developed by NREL and other Building America partners to help analysts compare whole-house energy use for a Prototype house to the Benchmark in a fair and consistent manner.« less
  • A methodology is developed to use residential demand-side planning to improve energy delivery in a manner which is mutually beneficial to the electric utility and its customers. The methodology examines the utility- and customer-related costs and benefits of altering system loads by introducing major electrical appliances of proven efficiency. Customers' responses to price fluctuations and time-of-use (TOU) rates, as well as attitudes toward various appliances and end-uses themselves, are examined. The primary focus is on an analysis technique to calculate appliance load profile changes which result from TOU rates. Utility planners can design rates which will improve the profitability ofmore » an appliance by molding its original load shape into one that is even more desirable for the utility. Nothing similar to this model been developed in any formal manner by a utility. The synthetic load profiles produced should prove to be very useful for cost-effectiveness analyses under time-of-use rates. Utility employees and state regulators have been known to treat TOU residential rates simply as means to save customers money rather than to effect mutually beneficial load shifts. The shifting methodology should help planned address the possibilities of both shaving peaks and increasing demand during off-peak periods. The general trends in electric appliance efficiencies and the availability of novel means of heating and cooking indicate that all-electric homes can be mutually cost-effective for both electric utilities and consumers. A hypothetical but realistic analysis is presented, and sensitivities of utility profits and customer costs to variation in energy usages, energy prices, capital costs, and various economic parameters are performed. Sensitivities to various TOU rates are also analyzed. Drastic TOU price differentials are necessary before either utility profits or customer costs are altered significantly.« less

  • Blue Heron Paper Company conducted a model-based energy assessment (MEA) to determine how to reduce effluent flow and heat load, minimize fresh water, and reduce process energy use at the company's Oregon City, Oregon, paper mill. Assessment staff recommended 15 projects, 7 of which the company considered. These projects would save an estimated 608,161 million British thermal units per year in natural gas and 990 kilowatt hours per year in electricity. Corresponding annual cost savings would be about $2.9 million per year. Furthermore, by reducing fuel requirements for the plant steam system, Blue Heron would also reduce stack gas emissions.
