Tips on Saving Energy and Money at Home Tips on Saving Energy & Money at Home “Technological advances and the development of energy-efficient products can help American families save a lot of money. Today, American families can choose refrigerators that use the same amount of power as a 75-watt light bulb, high efficiency light bulbs that last longer and require less electricity than traditional ones, and energy- efficient windows that can keep hot and cold air in and prevent hard-earned dollars from flowing out. Thanks to the development of innovative technologies, American families can make better energy choices.” – President George W. Bush “High energy costs can really pinch American families. While the Department of Energy is working hard to develop new technologies to improve the efficiency of American homes and buildings over the long term, today, there are simple, inexpensive steps families can take to re- duce their heating and cooling costs. I hope you will find this booklet helpful in making energy choices that are right for you and your family. As this booklet shows, when it comes to energy savings, a little effort can go a long way.” – Secretary of Energy Samuel W.

  • Actual and Estimated Energy Savings Comparison for Deep Energy Retrofits in the Pacific Northwest
    PNNL-21870 Prepared for the U.S. Department of Energy under Contract DE-AC05-76RL01830 Actual and Estimated Energy Savings Comparison for Deep Energy Retrofits in the Pacific Northwest J Blanchard E Giever S Widder M Baechler October 2012 PNNL-21870 Actual and Estimated Energy Savings Comparison for Deep Energy Retrofits in the Pacific Northwest J Blanchard E Giever S Widder M Baechler October 2012 Prepared for the U.S. Department of Energy under Contract DE-AC05-76RL01830 Pacific Northwest National Laboratory Richland, Washington 99352 Summary Seven homes from the Pacific Northwest were selected to evaluate the differences between estimated and actual energy savings achieved from deep energy retrofits. The energy savings resulting from these retrofits were estimated, using energy modeling software, to save at least 30% on a whole-house basis. Modeled pre-retrofit energy use was trued against monthly utility bills. After retrofits were completed, each of the homes was extensively monitored, with the exception of one home that was only monitored pre-retrofit. This work is being conducted by Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy Building Technologies Program as part of the Building America Program. Previous research has shown that realized savings from retrofit measures may not be consistent with energy savings estimates produced by modeling software (Lancaster et al. 2012; Parker et al. 2012; Polly et al. 2011). In previous studies, research has generally shown models to over-predict energy savings and energy use, especially in older, less efficient homes (Polly et al. 2011). Modeling occupant behavior has proved to be especially important for improved model accuracy and have found that detailed audit inputs, including operational behavior, can successfully increase the accuracy of models to within ±25% on a whole house basis (Parker et al.

Associate Dean for Research and Innovation Dean, School of Engineering Professor School of Engineering ii ABSTRACT PREDICTING RESIDENTIAL HEATING ENERGY CONSUMPTION AND SAVINGS USING NEURAL NETWORK APPROACH Name: Al Tarhuni, Badr Ibrahim University of Dayton Advisor: Dr. Kevin P. Hallinan Upgrading and replacing inefficient energy-consuming equipment in both the residential and commercial building sectors offers a great investment opportunity, with significant impacts on economic, climate, and employment. Cost effective retrofits of residential buildings could yield annual electricity savings of approximately 30 percent in the United States. This obviously could reduce greenhouse gas emissions in the U.S. significantly. Further, investment in energy efficiency can create millions direct and indirect jobs throughout the economy for manufacturers and service providers that supply the building industry. Unfortunately, the prediction in savings, which has been generally based upon energy models, has been circumspect, with energy savings typically over- predicted.
