The University of Florida will develop a technology for compact, low-cost combined water heating, dehumidification, and space cooling. This technology has the potential to save 480 TBtu/year in water heating and an additional 135 TBtu/year by reducing the air conditioning load.

Home Innovation Research Labs, Inc. will work to make the extended plate and beam system of incorporating insulation more accessible to builders through demonstration projects, technical documents, and code compliance assistance. Findings from these activities could play a critical role in improving the efficiency of home heating and cooling, which typically account for 40% of a home's energy consumption.

The Industrial Science & Technology Network, Inc. will develop an environmentally clean, cost-effective building insulation with superior performance. Commercialization of this technology would reduce U.S. energy consumption related to building envelope components by 7%, equal to $8 billion in annual economic savings.

Lawrence Berkeley National Laboratory will identify an alternative method to estimate two difficult-to-measure inputs used in building energy modeling. The end product will simplify and help automate the process of creating a calibrated model for existing buildings.

Argonne National Laboratory will develop an acoustic method of measuring the infiltration of a building envelope. The method will enable infiltration measurement of all buildings, which could lead to decreased building energy use.

Oak Ridge National Lab (ORNL), with its partner 3M, is developing adhesive chemistries for bonding aluminum and copper during heat exchanger manufacture, resulting in enhanced bonding and significant energy savings.

The purpose of this research is to develop and demonstrate an integrated humidity and ventilation control solution to improve indoor air quality, comfort, and energy performance for low-load homes in hot-humid and mixed-humid climates.

Optimized Thermal Systems, with their partners Heat Transfer Technologies, LLC, and interest from United Technologies Research Center, will develop a manufacturing procedure for a serpentine heat exchanger for heating, ventilation, and air-conditioning systems that has 90% fewer joints than current heat exchangers.

This project will enable production homebuilders to confidently construct market-ready homes at higher efficiency levels and empower manufacturers to design better products to meet production builder needs.

The Center for Energy and Environment and partners will field test and optimize an innovative new method for whole house air-sealing using aerosol sealant. This aerosol sealant method is already a proven duct sealing solution, and can reduce time and labor costs by simultaneously measuring, locating, and sealing leaks.

The University of Minnesota will field test an innovative insulated solid-panel building envelope system that (1) eliminates thermal bridging, improves durability, and reduces construction costs compared to conventional, wood-framed construction; and (2) is appropriate for the affordable housing market.

Pacific Northwest National Laboratory (PNNL) in partnership with a US based global manufacturing services provider will design, construct, and demonstrate an affordable heat pump clothes dryer (HPCD) suitable for the US market. A novel hybrid HPCD will be developed and demonstrated to save at least 50% of the energy used by conventional electric dryers, and will have a payback of less than five years for at least 25% of BPA residential customers.

The University of Minnesota: Twin Cities will field test an innovative insulated solid-panel building envelope system that (1) eliminates thermal bridging, improves durability, and reduces construction costs compared to conventional, wood-framed construction; and (2) is appropriate for the affordable housing market.

The Institute for Market Transformation will investigate whether investing in statewide building energy code education, training, and outreach programs can produce a significant change in residential building code compliance rates. The results of these activities provide the necessary business case to influence non-government entities, particularly utilities, to make investments in similar programs, which could lead to substantial national energy savings.

Clemson University, with their partners Harvard University, Phase IV Engineering Corp., and Iowa Energy Center, will develop, demonstrate and pre-commercialize low-cost, digital plug-and-play, passive radio frequency identification sensors for measuring indoor and outdoor temperature and humidity, which will improve building operations and cut energy costs.

High performance, low-load homes face unique space conditioning challenges that are not adequately addressed by HVAC design practices and equipment offerings. Equipment manufacturers have yet to include a diverse set of low-capacity equipment in their product offerings due to a lack of understanding of (1) where the low-load home market is headed and (2) the load profiles typical to low-load homes. This project looks to address both of these information gaps and ultimately send the necessary low-capacity equipment market signals to manufacturers, enabling them to design better products to meet production builder needs. The team will develop a technical whitepaper and presentation on the performance and cost tradeoffs of various equipment types/systems at meeting the comfort requirements of low-load homes, and forecasting the market penetration and equipment needs for these low-load homes.

Home Innovation Research Labs, Inc. will study a new approach to roof insulation retrofits that can be installed in one step and result in semi-conditioned attics. Findings from this project could play a critical role in improving the efficiency of home heating and cooling, which typically account for 40% of a home's energy consumption.

This project entails the measurement of time-integrated concentrations and temporal profiles of humidity and established contaminants of concern in a minimum of 64 new homes located in cold and marine climate zones.

This project is part of a national study aimed at characterizing indoor air quality in occupied homes. The homes will be up to current energy codes, and researchers will closely monitor the use and performance of mechanical ventilation systems in those homes. Indoor and outdoor air will be sampled for formaldehyde, nitrogen oxides, carbon dioxide, and particulates as part of the indoor air quality characterization.

During BPA's 2016 Multifamily Technical Advisory Group, this technology was evaluated and recommended for future research. BPA is joining with NEEA and Ecotope to conduct a bench test to determine if this will be a viable alternative to conduct future field tests in the Pacific Northwest. The bench test will be document the system performance and noise levels to determine if the unit is ready for more lab and field tests.

This project will develop test procedures for alternative refrigerants for flammability and energy savings characterization and to develop a “favorability” index of end-use market segments and equipment types based on potential GHG savings impact and commercial feasibility and adoption.

The Better Buildings Residential Network connects energy efficiency programs and partners to share best practices and learn from one another to increase the number of homes that are energy efficient. Better Buildings Residential programs and partners have invested more than $3 billion from federal funding and local resources to build more energy-efficient communities across the United States. The U.S. Department of Energy (DOE) is continually expanding this network of residential energy efficiency programs and partners to new members.
