Project Abstract
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.
Project Abstract
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.

Project Abstract

The Automated Cloud-based Continuously Optimizing Building Energy Management System (ACCO-BEMS) overcomes limitations of existing energy management systems by automating optimized control of building systems and devices. The technology overcomes limitations of existing energy management systems and eliminates the need for expensive reprogramming needed to implement optimization measures. As such, the technology can co-exist with existing systems in retrofit applications, or it can be implemented as a new installation.

Project Abstract
This project demonstrates three innovative bundles of pre-commercial technologies. The technology bundles were strategically developed through a systems-level approach to address the most energy-intensive areas in commercial buildings. These include: (1) Chilled Water Plants: Optimized all-variable-speed chilled-water (CHW) plants utilizing alternative refrigerant chillers. (2) Office and Exterior Space LED fixtures with integrated advanced controls, advanced building management system (BMS), and plug load controls controllable for demand response (DR), and off-grid, exterior, LED lighting in the parking lot, and lastly (3) Advanced laboratory ventilation, fume hood exhaust, and direct current (DC) lighting systems.
Project Abstract
This project will develop and demonstrate a Climate Appropriate Air Conditioning system for commercial buildings. The heart of this system is an intelligent HVAC controller that processes signals from building sensors and system feed-back to maximize system efficiency. This control system will manage two technologies to optimize building energy and peak demand reduction. Getting fresh air into commercial buildings is a code requirement. However, the ingress of hot air into a cooling system and vice versa presents an inefficiency problem. This project will evaluate heat-recovery ventilation (HRV) and indirect evaporative cooling (IEC) to decrease the temperature of the incoming air in the summer and increase it in the winter. Both technologies can be intelligently controlled by the building controller to reduce cooling and heating costs. This project will also research low global warming refrigerants for commercial buildings
Project Abstract
The project will focus on the performance of different attic assemblies and their associated heating, ventilating and air conditioning (HVAC) systems. Field measurements of attic and HVAC system performance will be conducted in two new high performance homes in California with sealed and insulated attics. One home will be built to be about 30 percent better than Title 24 and the other will be a ZNE home. The attic insulation approach will be a new lower-cost approach using blown insulation that does not use expensive spray-foam. The results of the measurements will be used directly to provide technical support for potential changes to Title 24 and provide information to contractors and builders on sealed and insulated attic performance and alternative approaches.

Project Abstract
Three different attic designs will be refined, tested, evaluated, and demonstrated in new home construction. The team will recommend the best of these approaches to home builders addressing cost-effectiveness and energy-efficiency. The baseline for comparison will be current energy efficiency code practices for attic construction involving ventilated, uninsulated attics containing code compliant ducts. The team will evaluate the new design approaches analytically at the start of the project. Researchers will assess approaches that include methods to produce sealed, insulated attics, as well as, standard vented attics, both of which have been demonstrated and are in limited use in the market today but currently add considerable cost to builders. The team will employ new and novel installation methods and materials that have the potential for energy savings on par with ducts in the conditioned space, but at a cost similar to current practice.
Project Abstract
This project will assess factors affecting the scale of solar water heating (SWH) installations, such as system cost, performance, and reliability and scale.

The project team will consider different SWH technologies, installation types and financing mechanisms and develop a model to address questions on investing in solar water heating and how investments can be focused to maximize uptake of SWH. The team aims to quantify state-level energy and emissions impacts of the reduction in natural gas usage from solar water heating installations.

Project Abstract
This project will develop a low cost smart thermostat unit that will have simple user interface. Though the test sites are low-income and senior housing, this technology could be adapted to other residential sectors. The smart thermostat will understand user preferences and manage indoor conditions to optimize energy use without requiring internet connectivity. HVAC energy use can be traced to three factors: losses in the ducting system, substandard equipment efficiency and occupant settings. Low income households are mostly renters which makes changes to the duct system or HVAC unit not feasible. By providing automatically optimized thermostat settings this project will determine if smart thermostats are a cost effective method to address HVAC energy use in the low-income and senior housing sectors.
Project Abstract

The project team is demonstrating and validating new retrofit package solutions from laboratory pre-testing through field demonstrations in existing government-owned commercial buildings. The solution sets, dubbed "INTER", are comprised of shading products from Rollease Acmeda and lighting and plug load systems and integrated controls, including HVAC systems, from Enlighted. The technologies can be combined and customized to suit a variety of building types and spaces, resulting in an estimated whole building energy reduction of 20 to 32 percent. Beginning in the Los Angeles basin, the team is leveraging existing market connections to increase and accelerate market adoption of these retrofit solution sets to maximize the potential energy and carbon savings, first in the region and ultimately, throughout California.
