Like a miles-per-gallon rating for a car, the Home Energy Score is an easy-to-produce rating designed to help homeowners and homebuyers gain useful information about a home's energy performance. Based on an in-home assessment that can be completed in less than an hour, the Home Energy Score not only lets a homeowner understand how efficient the home is and how it compares to others, but also provides recommendations on how to cost-effectively improve the home's energy efficiency.

The Home Improvement Catalyst (HI Cat) is a new DOE initiative focused on high impact opportunities to achieve energy savings in home improvements already planned or being undertaken by homeowners. The Home Improvement Catalyst is designed to identify the multiple pathways to achieving an energy efficient home through energy upgrades and speed the adoption of market-ready energy improvements; resulting in greater energy savings over time.

The Home Upgrade Program Accelerator is designed to help home energy upgrade programs bring services to more homes across the country by leveraging data management strategies that minimize costs while improving overall program effectiveness. These programs are currently completing hundreds of thousands of home upgrades annually with average savings of 20% for participating households.

Carnegie Mellon University will design, implement, and evaluate a human-in-the-loop sensing and control system for energy efficiency of heating, ventilation, air conditioning (HVAC), and lighting systems based on a novel occupancy sensor. Through occupant sensing and real-time data collection, this project will reduce energy waste, targeting a 20% energy savings, while increasing occupant comfort by accurately estimating occupants in an area to overcome current HVAC system operations.

Throughout the development of the AVS resources and meta-analysis, HI Cat will conduct outreach to EPA, utilities, CEE, REEOs, and program implementers seeking to advance programs that advance high performance HVAC and QI practices. DOE is partnering with MEEA to collect data and evaluate the HVAC SAVE program (Iowa), test approaches to offering additional services, and develop a case study of the HVAC SAVE program in Iowa.

This project will combine electrochemical compression technology with ionic liquid desiccant to provide the most efficient means of managing latent and sensible heat loads in air-conditioning (AC) systems. This technology replaces the standard mechanical compressor commonly found today in AC systems with an electrochemical compressor that utilizes fuel cell technology to enable efficient heat pump systems.

The University of California, Santa Barbara, will identify the fundamental causes of current droop in state-of-the-art commercial LEDs. These findings will lead to development of higher-performing LED lighting technologies.

With a focus on typical business as usual HVAC trade practices, HI Cat seeks to capture greater efficiency at high volume within the home improvement transactions at key decision points. HI Cat will work in partnership with industry to design contractor ready resources via development of a Sequencing Tool that curates advisory content that can be applied during the sales transaction. The sequencing tool, designed for use by trade contractors, will identify opportunities to improve upon the current transaction in any given scenario, without disrupting it. Related resources, such as a contractor playbook, will provide ing relevant sales tools and tips; selection, specification, and field installation guidance; proposal and contract language; etc. It will also offer messaging about the energy efficiency pathway or customer journey, reference applicable DOE and industry technical standards/guidance and provide technical information to address follow on EE opportunities.

Trane, in partnership with the University of Illinois, will develop engineered microstructure surfaces that will reduce refrigerant leaks and enhance HVAC&R systems efficiency by improving the strength and quality of brazed joints.

Lumileds, LLC will develop structures that will dramatically improve efficiency droop. The improvement in droop will be utilized to achieve higher performing LEDs.

This project will improve the external quantum efficiency (EQE) of amber and red aluminium gallium indium phosphide (AlGaInP)-based LEDs by developing strain-engineered cladding layers to provide enhanced carrier confinement.

the University of Miami, in partnership with Schneider Electric and Lawrence Berkeley National Laboratory, will create a tool for dynamic cooling and airflow optimization that is customized for the design and operational requirements of data centers and computer rooms by integrating several open-source modeling packages: the Modeling Buildings Library/Spawn-of-EnergyPlus for flexible IT equipment and cooling system modeling; LBNLs GenOpt for optimization; and the University of Miamis Fast Fluid Dynamics package for airflow modeling.

As part of an ongoing effort to enhance low-power wireless communication, this project will develop a wireless connectivity module made of radio frequency (RF) hardware and systems software that enables RF connectivity at over 50% lower active power consumption for integration into MELs.

OLEDWorks will reduce OLED manufacturing costs by developing innovative high-performance deposition technology. If OLD costs can be reduced to enable OLED lighting to make up 5% as large a market as LEDs by 2025, OLED lighting will save approximately 10 TWh/year.

Philips Research North America will develop an innovative LED office lighting system that integrates light delivery, optics, and controls. The office portfolio developed in this project will maximize energy efficiency and occupant health and well-being.

Philips Research North America will develop an innovative LED lighting system for patient rooms. This solution will be energy efficient and will meet all the needs of patients, caregivers, and visitors.

The project will study the integration trade-offs, cost and energy optimization of daylighting, LED electric lighting, plug load sensors and zonal air plow controls. If widely adopted, the integrated controls package in this project could have savings up to 750 Tbtu per year.

The Levy Partnership, Inc. will develop low-cost, highly efficient comfort system designs to enable affordably built homes to use heat pumps with superior air distribution systems. This demonstration could result in 50% energy savings over 2009 code requirements.

This project will further refine a new approach to using mini-split heat pumps in existing homes. The team will focus on using a single, centrally located mini-split heat pump as the primary system, while only using the existing lower efficiency central system as needed.

Sinovia Technologies will combine a barrier film technology with a nanowire transparent conduction film to make a single substrate product for OLED lighting. This technology will improve the efficiency and lower the cost of OLEDs.

This project studies the synergistic interactions of daylighting, plug controls, automated fault detection and diagnostics (AFDD) and HVAC optimization. If widely used, the package of daylighting techniques, plug loads, AFDD and controls for HVAC systems validated in this project could have savings of 756 Tbtu per year.

This project focuses on establishing a framework and identifying priority R&D needs for coordination with industry, Emerging Technology and market deployment programs. PNNL will develop a white paper evaluating the state of the art of commercially available sensors and controls technology for operations, maintenance, and commissioning applications in residential HVAC. This work assesses technology gaps and market needs, and provides clear recommendations for government action and industry involvement in advancing sensors, controls, diagnostics, and automated fault correction. The task will explore opportunities for industry engagement to gain feedback on report findings, better identify industry development plans, and focus BA/BTO investments.

This project will attempt to measure the impact of lighting on the users of an outdoor lighting space. The experiments will determine the effects of different lighting types on the melatonin levels of the participants. As different CCT light sources will be used, their differing spectral contents can be evaluated to determine the most appropriate light source for implementation in the outdoor environment.
