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.

The purpose of this agreement is to fund the full-scale deployment demonstration of the Vortex Process Technology in cooling towers of commercial buildings. This technology has been used successfully in Europe and will be testing in California to address state specific goals for water and energy savings

This project will demonstrate how a large number of small electric loads, each impacted by and tuned to individual customer preferences can provide load management for both utilities and the California Independent System Operator (California ISO). The recipient will work with an extensive spectrum of leading product providers covering all major distributed energy resources (DERs), such as Nest (thermostats), ThinkEco (plug loads), Honda, BMW (auto), EGuana (smart Inverter) and Ice Energy (Thermal Storage).

This project will contain three elements to provide data for policymakers and businesses to explore this new market. First, this project will determine prosumer (proactive consumer) interest in a third-party demand response market by testing user acquisition via direct and non-direct engagement strategies. Second, experimentation with behavioral and automated users will allow analysis of user yield under a variety of conditions and extract a set of shadow curves that can inform how much energy load shifting can be expected under various price incentives. Finally, this project will create a novel solution for using residential telemetry to connect prosumers and their Internet of Things (IoT) devices to the market operators.

This project will develop and evaluate cost-effective packages of pre-commercial integrated energy efficiency measures and controls to achieve zero net energy (ZNE) performance for multi-story small commercial offices in San Francisco and Southern California. The packages will target a minimum of 50 percent energy savings when compared to standard building energy use. The packages of energy efficiency measures will be analyzed at Lawrence Berkeley National Laboratory's FLEXLAB, an advanced facility for testing whole-building integrated systems, to develop and validate solutions under varied climate and use conditions. The simulation models will be validated through results from FLEXLAB testing and a 3-story whole-building demonstration pilot located in San Francisco. Data on energy, occupant comfort, and occupant behavior will be analyzed and packaged into best practices to be replicated elsewhere in the State.

The project will implement lessons learned from previous high performance housing research and measure the results in two new houses built in partnership with Habitat for Humanity and homeowners. The houses will be built in a disadvantaged community in Stockton. Each house will include advanced architectural design features, high performance enclosures, advanced heating, ventilating and air conditioning systems, low-cost water heating systems and other advanced energy efficiency measures. One all-electric home and one mixed fuel (combined electric and natural gas) home will be built to demonstrate the respective costeffectiveness of each set of features. In addition to the measured results from actual occupancy, the project will develop a guide to affordable residential zero net energy design and construction, training curriculum, and new class offerings based on the project results for building practitioners.

The recipient will use EnergyPlus, a building energy modeling tool, to analyze the costeffectiveness of various electricity saving/generation measures for multifamily and commercial buildings in California. For each building type and climate zone, the results will include a cost-benefit analysis for each measure individually and for an optimized package of measures that reduces net electricity consumption to achieve as close to zero net energy as is cost-effectively possible.

The project will provide detailed cost effectiveness modeling of all electric zero net energy (ZNE) homes versus ZNE homes with gas-based heating. Evaluation will include costs of building integration, energy efficiency packages, installed equipment and lifetime investment costs such as energy costs, and infrastructure costs (natural gas pipeline and electricity distribution system). The project will provide both spatial and temporal analysis in providing cost effectiveness assessment in four California climate zones and provide cost evolution scenarios as a function of time, for example as the ZNE industry scales up and under various policy and energy cost assumptions. The analysis will provide policymakers with a better understanding of the costs and benefits of ZNE policy choices between today and future ZNE milestones (2020, 2030), and the trade-offs for all electric versus electric and gas households

This project will integrate water features into a novel heat exchanger which uses high performance porous fins to enhance cooling ability. Bench scale testing has shown the ability of the heat exchanger to enhance cooling through water vaporization and mass transfer. By integrating the proven heat exchanger with water features, this project has the potential to create a low cost and low risk product to reduce electric power and water use of refrigeration systems in California.

This project will integrate pre-commercial energy efficiency measures, building automation and controls system, behind the meter solar photovoltaic and energy storage in three existing public libraries in the City of San Diego. In addition to demonstrating cost-effective pathways to achieving maximum energy efficiency in the small commercial/municipal building sector, the recipient will engage in a multiyear, flexible, and transparent collaboration aimed at uncovering, testing, verifying and publicizing strategies for integrating energy efficiency, energy storage, solar photovoltaics, and other demand side resources to achieve near zero net energy in each library and to evaluate the financial value proposition.

This project researched new phase change materials (PCM) to store thermal energy for wall assemblies, and develop associated software tools. Heat is absorbed or released when the materials change from solid to liquid or vice versa. PCMs absorb thermal energy and they can reduce the need for heating and cooling in some buildings. Their impact is similar to that of adding thermal mass to the building. Unlike air conditioning systems, they require no maintenance. The use of PCMs and associated software tools can contribute to zero net energy commercial buildings by reducing the energy needs of a building through passive design.

The project will serve as proof of concept for large-scale deployment of zero net energy (ZNE) single-family homes in California. The objective is to construct ZNE homes without creating undue cost burdens on businesses or consumers, while assuring that changes to home design do not pose health, safety or other risks to occupants. Additionally, the project will provide industry and regulators with a better understanding of the assumptions associated with site energy use and renewable energy generation and will provide resources to builders to assist them with controlling costs on ZNE home construction.
