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.

This renewable-based direct current (DC) microgrid will connect on-site generation with loads and provide a low cost, energy-efficient solution to save costs. Solar PV will be directly connected to energy-efficient DC lighting, DC energy storage systems, and ventilation on a 380 V DC bus to form a DC building microgrid. This microgrid system proposed for the Honda Distribution Center in Chino, California reduces the need for inverters for PV and rectification equipment in the loads, thus improving the overall utilization of solar energy by 7-10% as compared to conventional AC systems, while lowering component complexity and costs.

This proposal responds to BPA TIFO Interest Area 7, Cold Climate Heat Pump Water Heaters (HPWH). We propose to develop and demonstrate a novel integrated HPWH customized for demand response (DR) and efficient operation in cold climate homes.

Seventhwave's Accelerate Performance scales owner demand for energy performance at a cost comparable to current construction by eliminating key market bariers. This program will achieve an average of 50% realized savings compared to traditional 30% modeled savings for aggressive new construction projects.

This project will demonstrate the potential of breakthrough electric water heating and space conditioning technologies as a pathway to zero net energy. The project will explore the complex, interdependent systems in multifamily buildings and how they work together to achieve zero net energy status for the buildings in a cost-effective manner. Four multifamily buildings, designed to be affordable, will be evaluated in various stages of design and development. These buildings will share a goal of all electric zero net energy construction with 100 percent renewable energy generation, and will utilize innovative new heat pump technologies to serve the buildings water heating and/or space conditioning needs.

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.

This work will determine the savings and the cost-effectiveness of advanced rooftop unit controller (ARC) Light Retrofits. This work will support a new evaluated measure through the development of a Standard Protocol, based on 38 Zeros meters and the ARC retrofit fan-only analysis. Utility grants will fully fund the installation of up to 30 ARC Light Retrofits, where 38 Zeros meter installations are also fully funded, with one-year of data hosting. (ARC Light Retrofits are expected to cost around $2,000, while the 38 Zeros meter installations are expected to cost around $1,500, including one year of data-hosting and retrieval of the 38 Zeros meter.) All grants will be paid by 9/15/15 because of the inability to spend money in the new rate period. Based on EER feedback, utilities will claim self-funded (non-EEI) savings as FY15 custom projects.

Southface Energy Institute will develop energy efficiency evaluation and upgrade tools that provide at least a 50% energy improvement in new construction and a 20% energy improvement from upgrades to existing buildings, as well as develop energy audit training materials. These tools and training materials will help spur energy efficiency gains in new and existing buildings.

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.

BuildingIQ, Inc. will optimize HVAC energy use across commercial buildings using a cloud-based software application that automatically adjusts temperature set points to reduce energy consumption. This software could reduce HVAC-related energy use in commercial buildings by 12% - 25%.

The goal is to develop a standard protocol to verify site-based savings for advanced rooftop unit (RTU) control (ARC) retrofits, based on manufacturer variable frequency drive (VFD) data. This will streamline the acquisition of 1 aMW of ARC retrofits and lower the cost of the impact evaluation. This project will draft a standard protocol to verify ARC retrofit site-based savings using Catalyst controller data. The project will compare best practice (unit-level, true-power over one-year with daily baseline cycling, as reported in Pacific Northwest National Laboratory (PNNL) study) and four simplified savings methods, to determine a simplest-reliable method. Deliverables include a draft protocol and presentations to the RTUG and, if appropriate, to the RTF. Once approved, the standard protocol would allow the streamlined acquisition of ARC retrofits because baseline metering and long-term baseline cycling would not be required. Once 1 aMW of ARC retrofits (approximately 1,000 RTUs) are reported, several years of Catalyst controller data would be available for most of the units for the impact evaluation. Using the standard protocol and manufacturer data, no post-post cycling or additional instrumentation, such as Wattnodes for unit-level true-power, will be required.
