The project will bring the proposed solution through the prototyping phase into laboratory and field tests.

Power Management User Interface

This project seeks to reduce computers' energy consumption by improving how users employ existing power management capabilities. Although all computers have the capacity to enter low-power modes such as sleep, and can be shut down when not in use, this potential for energy savings has not been realized in the majority of desktop computers. The majority of desktop computers remain on at full power when they are not being used. The problem is one of user behavior. The project will use a software solution to change user behavior by changing the tool they are using. This approach is firmly based in behavior theory and human-computer interaction research, which have long demonstrated that the interface of a device can change users' behavior. The energy savings of applying such an interface is estimated to be as high as 50 percent per computer, between 139 and 321 kWh per year.

Race to Zero Student Design Competition

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.

Reverse Cycle Chiller Distributed Heat Loss

This project proposes to research an issue which was identified during the current reverse cycle chiller (RCC) study regarding distributed heat loss. This project builds on an existing BPA funded multifamily heat pump reverse cycle chiller project, TIP 140. The results of this project have been good. This is a technology which has potential for multifamily and other applications in the Pacific Northwest. The TIP 140 project results identified that hot water recirculation systems can reduce efficiency by 30-40%. Additional work needs to be done to quantify the energy losses associated with typical hot water distribution systems. This research project contains a comprehensive approach to understanding and reducing energy losses in hot water recirculation systems. There are three work areas. The primary area is a pilot study to set up three different hot water distribution systems and understand the impact these three different approaches will have on the overall system efficiency. The second area is to meter actual heat loss from recirculation systems in two to three existing midrise multifamily buildings to better characterize the baseline. The third area is to directly measure performance of inverter-driven heat pump water heaters in the field with and without the impact of recirculation loops.

Sensitivity Analysis of Humidity in Low Load Homes

The Building America Space Conditioning Standing Technical Committee and Expert Meeting reports identified high relative humidity as one of three issues with the highest technical priority for ensuring comfort in low-load homes. As such, the primary objective of this project is to evaluate factors that can contribute to high relative humidity in a home (variations in internal loads, equipment sizing, and equipment setup) and quantify their relative magnitude of impact on indoor relative humidity. A technical white paper will assess the sensitivity latent and sensible gains have on comfort and recommended system sizing. This will inform R&D needs for future BA/BTO work, provide actionable information to manufacturers on the equipment needs of low-load homes (see related project, Assessing the Market and Space-Conditioning Needs of Low-Load Homes), and provide system design and sizing guidance to contractors.

Smart Ventilation Controls

To reduce energy use in homes that are becoming tighter, mechanical ventilation is added to maintain Indoor Air Quality (IAQ). Smart ventilation technologies are being developed to minimize the energy impact of mechanical ventilation while simultaneously maintaining IAQ. This project will demonstrate the energy savings associated with a smart ventilation technology through a combination of field testing and simulations. The target is to get close to heat recovery ventilation (HRV) performance at much lower cost and complexity; and greater reliability through smart control of simple exhaust (or supply) fans. The project will also develop recommendations for utility programs, other energy efficiency programs and for codes/standards on how to calculate credits for smart ventilation systems.

Tools and Materials for Zero Net Energy California Buildings

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 central management system that this project will demonstrate is well positioned to provide comprehensive control over diverse plug-load devices.

This project is funding the planning, permitting, and preliminary engineering needed for the integration of advanced energy technologies in a disadvantaged community. The design will provide locally generated, GHG-free electricity from community solar and storage to offset electricity consumption of participants who opt in to the AEC. The design will also enable participants to benefit from savings resulting from various onsite Integrated Demand Side Management (IDSM) actions at no up-front cost, including energy efficiency retrofits, demand response, energy management systems, and an energy education and support program. Participants will pay back retrofit costs and cost of capital for solar and storage assets through an on-bill financing mechanism, including a first-of-its-kind virtual net metering (VNEM) tariff across multiple county-owned sites and residential buildings piloted by Los Angeles Community Choice Energy (LACCE). The project has a strong focus on local outreach and engagement to promote community participation in the AEC, as well as robust data evaluation methods facilitated through the LA County Energy Atlas to ensure design and financing features are optimized.
