Campbell Creek TVA 2010 First Year Performance Report July 1, 2009 August 31, 2010

摘要

The Campbell Creek research project supports the retrofit residential housing goals of the Tennessee Valley Authority (TVA) and the U.S. Department of Energy. Data from the first year of the project, which was initiated by TVA in March 2008, were collected from three houses of similar size, design, and solar and wind exposure, all with simulated occupancy and all located in the Campbell Creek community of Farragut in west Knox County, Tennessee. All of the houses have simulated occupancy-automated mechanisms replicate the occupancy of a family of three, including regularly opening and closing the refrigerator, using the oven, running the clothes dryer, or taking a shower. The three study houses can be characterized as follows. The Builder House (baseline house, or CC1), representative of a standard, IECC 2006 code-certified, all-electric house built by the builder to sell around 2005-2008. The retrofit house (or CC2), which included modifications that could be made to existing houses to improve energy efficiency. The data collected from CC2 will be used to evaluate the impact of energy-efficient upgrades to the envelope, mechanical equipment, or demand-response options. The third house (or CC3) was designed as a transformation of the CC1 (builder house) with the most advanced energy-efficiency features, including solar electricity and hot water, that market conditions are likely to permit within the 2012-2015 period. This report covers data collected from CC1, CC2, and CC3 during the performance period from July 1, 2009, to August 31, 2010. TVA will use these data to determine the benefits of retrofit packages and high performance new home packages. The data will also help builders and homeowners make smart decisions about products and technologies when retrofitting existing houses and building new high performance houses.
