Located here are resources to better your knowledge on quality installation and performance testing building science principles.

U.S. Department of Energy’s Building America research has been done through multidisciplinary partnerships that work to make high performance homes a reality for all Americans.  Specific research regarding quality installation methods were done through the Partnership for Advanced Residential Retrofit (PAAR). Led by the Gas Technology Institute, the team’s goal has been to increase the quality and uptake of residential retrofits by demonstrating innovative, scalable, and cost-effective solutions that enable market transformation.  Specifically, the team focuses on cold climates and a systems-based approach to integrating heating and cooling advancements with sound building shell principles. The following two papers are examples of this research that directly relate to HVAC SAVE.

  Energy Savings from System Efficiency Improvements in Iowa’s HVAC SAVE Program

(S. Yee, J. Baker, L. Brand, J. Wells, August 2013) 

MEEA worked in conjunction with PARR team members to collect pre-and post-system upgrade data from 48 existing homes in Iowa to analyze the energy savings associated with the HVAC SAVE program for space heating.

  Improving Gas Furnace Performance: A Field and Laboratory Study at End of Life

(Brand et al. 2013)

MEEA worked in conjunction with PARR team members to collect and analyze working furnaces that were removed from Iowa homes. The purpose of this research was to investigate the impact of age degradation and typical installation practices on the steady-state furnace efficiency.

The National Institute of Standards and Technology’s mission is to promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve our quality of life.

  Sensitivity Analysis of Installation Faults on Heat Pump Performance

(Domanis, Henderson, Payne 2014)

This research report is the first to quantify efficiency losses due to common contractor installation errors documented in field surveys.  The research team determined how each installation error affected energy consumption in the lab and then compared that to how the same errors may impact energy use in two types of homes and in five different climate zones.

  HVAC SAVE: A Case Study in the Next Evolution of Residential Quality Installation Programs

(Edwards, Baker, Graham, 2015)

Iowa’s HVAC SAVE program emerged from the notion that operating performance of heating and cooling equipment does not equate to out-of-the-box rated performance. Because these appliances can’t simply be plugged into the wall and perform as designed, a contractor can deliver greater levels of efficiency by optimizing and verifying the performance of the installed equipment. Together, MEEA and ESI developed the HVAC SAVE program to train and certify HVAC contractors in the skills necessary to determine in-place efficiency of functioning HVAC systems. Energy Stewards International (ESI) is a company that has years of experience in training HVAC professionals on how to use static pressures, system temperatures, and airflows to identify existing system deficiencies, allowing them to make targeted repairs or adjustments. The HVAC SAVE program launched in Iowa in the fall of 2010 and has trained over 2,300 contractors throughout Iowa and Illinois on VQI and performance testing practices. This White Paper will provide an overview, analysis, and summation of best practices of the program as it has evolved since 2010 through the fall of 2015.
