Problem StatementThe California Residential Building Energy Efficiency Standards are widely respected as the best in the United States, but they apply primarily to new construction which in normal economic conditions is a tiny number of new homes (and this year smaller yet) compared to the existing stock. The vast majority of California homes was built under earlier, less stringent versions of the Residential Standards or predates standards entirely. The majority of these homes offer cost effective opportunities for significant efficiency upgrades and, because of the number of existing homes, the total opportunity for savings is many times larger than can be expected from improvements in new construction going forward.

Current energy calculation tools have an abysmal record at estimating the energy use and energy efficiency of poorly insulated existing homes. The contractor compared Home Energy Rating System (HERS) I ratings with utility bills for the California Energy Commission (Energy Commission) and Pacific Gas & Electric (PG&E) and reported,1 as shown in the figures above, that HERS calculations overestimated heating energy consumption by a factor of four and that higher rated homes actually used more cooling energy than low rated homes. Presumably this performance has been improved some by the Energy Commission adopted rules for HERS calculations going into effect in 2010 (HERS II), but it is believed a detailed comparison with data from unoccupied homes could validate and probably significantly improve HERS calculations for use in California efficiency upgrade programs.

There is currently no facility that provides the opportunity the contractor is proposing to collect detailed data under controlled conditions in older California homes. The development of HERS procedures has been hampered for years by the lack of data to validate energy calculations in older homes. Most current energy use data is derived from utility bill analysis, surveys, and monitoring in occupied homes in which the presence and behavior of occupants precludes detailed monitoring and the problems with incentive programs obscures the performance of measures.

Many efficiency measures that are required for new buildings in the California standards are considered too expensive for retrofit applications. For example, low solar gain, low U-factor windows with air tight sash are required in new construction, but improved windows are generally viewed as too expensive for retrofit programs. Team member Grupe is starting a 500-house retrofit program in Stockton where they plan to install heat absorbing window films on leaky single glazed aluminum windows as an “efficiency upgrade,” based on their analysis of the costs and performance of retrofit windows. However, there is little to no actual data on the energy and peak demand savings that would be delivered by modern high performance replacement windows and other efficiency upgrades or what they would cost as part of a high volume well organized retrofit program.

Goals of the AgreementThe goal of this Agreement is to provide and maintain four laboratory homes where energy use and energy efficiency in existing homes can be scientifically studied and the results applied to:

Improving calculation methods and HERS ratings

Developing analytical approaches and optimized packages of retrofit measures for typical existing homes

Informing local and statewide energy efficiency programs

Providing a test facility for emerging retrofit technologies

Objectives of the Agreement

The objectives of this agreement are to:

Use the (Project Advisory Committee) PAC and the local real estate expertise of Green Home Solutions by Grupe (Grupe) to specify and find representative test homes in or near Stockton which Cardinal Glass will purchase for and provide for project use.

Use the Building Performance Contracting expertise of Rick Chitwood and Grupe to carry out a complete survey and full suite of diagnostic tests to characterize and document the energy features of the homes.

Hire multiple HERS raters to rate each home and compare their ratings, energy use estimates and efficiency upgrade recommendations as a test of the new HERS II process. Compare the HERS measured characteristics with the team’s measurements. Save the HERS estimates for comparison with measured energy performance of the homes before and after retrofit and report results.


Install and commission the separate indoor reference heating, ventilation, and air conditioning (HVAC) system (electric heat, no distribution losses) using the approach developed by this team in the Cardinal Fort Wayne project (a Field demonstration of the performance of LOE2 glass in four instrumented, unoccupied homes in Fort Wayne, Indiana, ongoing since 2003).

Install and commission the Cardinal provided monitoring and control systems, using the expertise of the team who have thoroughly debugged them for the last five years in Cardinal’s Fort Wayne Project.

For the first year of the project operate all four of the houses with as-found energy features to generate a baseline hourly data set on the loads and HVAC efficiency of representative existing central valley homes. Alternate running the as-is HVAC system and the reference HVAC system in each home to separate loads and system interaction effects and report results.

Compare HERS II estimates of as-is home energy consumption with measured data for the four homes using John Proctor’s analysis expertise and report the results.

Develop improved input rules and simulation algorithms to improve the accuracy of the HERS II estimates of as-is home heating and cooling energy use using Phil Niles heat transfer modeling expertise, implement them in a development program using Ken Nittler’s programming expertise and report results.

With PAC input, develop packages of envelope and HVAC efficiency upgrades which are designed to achieve 50 to 75% savings in heating and cooling energy in the experimental homes, using techniques which could be cost effective when applied as part of a multi-house optimized upgrade program and report results. Wilcox will lead with significant input from Proctor, Chitwood, Larsen, Faulkner, Grupe and Nittler.

Install an envelope (insulation, windows, air sealing, cool roof) and HVAC upgrade package (ducts, fan motors, optimized controls, High Annual Fuel Utilization Efficiency (AFUE) and Energy Efficiency Ratio (EER)) in each home using the resources of Chitwood and Grupe and operate the homes for the second year to collect heating and cooling data on the reduction in loads and increase in efficiency. Cardinal will contribute advanced retrofit glazing systems and Polyfoam will contribute cool roof systems for testing. Flip flop the HVAC system with the reference HVAC system in each home to separate loads and system interaction effects.

Compare the measured performance of the efficiency upgrades with the HERS II estimate using John Procotor’s analysis and report the results.

Develop input rules and simulation algorithms to improve the accuracy of the HERS estimates of envelope and HVAC efficiency upgrades, implement them in the development program and document the results. Wilcox will lead with significant contributions from Niles, Proctor and Nittler.

Based on second year results, develop and test alternate glazing systems and possibly other measures during the third year of the program.

Install alternate HVAC distribution systems such as multi-zone dampers or mini-split heat pumps in the homes and alternately operate them with the reference HVAC systems to


determine the impact of these systems on energy use and peak demand and report results. Wilcox will lead the effort with Proctor providing analysis and Chitwood the installation supervision for subcontractor Grupe.

Summarize the program results in a final report.
