Water heating represents approximately 18 percent of residential energy consumption annually. Heat pump water heaters (HPWHs) offer an efficient option for residential water heating, because they have the ability to reduce water heating energy consumption by up to 63 percent. To achieve such high efficiencies, HPWHs employ a refrigeration cycle to move heat from the ambient air into water stored in a tank. When HPWHs are in conditioned space, they remove heat from the conditioned air. This study conducted during the winter of 2016 - 2017 provides an objective evaluation of the space conditioning interactions between a HPWH and the heating system in several locations throughout a home to investigate the impact that HPWHs have on space conditioning loads. We have always known there was an interactive effect with home heating systems. This study provides a detailed look at how much and the findings show that there is less interaction effect than we originally thought.

Heat pump clothes dryers are significantly more energy efficient than conventional (ENERGY STAR®) electric resistance clothes dryers. The goal of this project was to determine whether heat pump clothes dryers offer non-energy benefits—specifically, reduced clothing wear and tear—that could help consumer adoption. Multiple machine types ran over 100 dryer cycles, using loads specifically chosen to reflect a variety of fabric and fiber types. This project did not conclusively find that heat pump clothes dryers cause less wear than conventional dryers. However, the project was able to show that they do not cause more wear than conventional ENERGY STAR dryers. This project was a co-funded effort lead by Northwest Energy Efficiency Alliance with Pacific Gas and Electric. Over drying is a common occurrence in clothes dryers which are not ENERGY STAR certified and that do not have good automatic termination controls. This report contains an addendum to the Clothing Wear and Tear of Heat Pump vs. Electric Resistance Clothes Dryers study that investigated relative wear impact of heat pump clothes dryers compared to ENERGY STAR dryers. In this project additional cycles tested whether over drying from a conventional dryer caused additional clothing wear. The cycles were set to replicate the equivalent over drying that would occur in a dryer which is not ENERGY STAR certified over the course of 1-2 years. The project did not find statistically significant incremental damage to clothing from moderate over drying.

The measurement method of television energy consumption has been largely consistent within the United States for the last decade. TVs have improved remarkably in energy efficiency during that time. It is important to understand how much of those apparent energy savings are the result of fundamental improvements to TV technology itself versus optimizing how TVs perform under the specific conditions of the test procedure. Early in 2016 Northwest Energy Efficiency Alliance (NEEA) recognized that a substantial body of emerging research was pointing to serious flaws in the current U.S. TV test procedure and energy use assumptions. As a result, NEEA commissioned this research and report to better understand how to improve the test procedure, what qualities a new test clip should possess, and how to make progress toward an optimal long-term test procedure in the interim to better inform current labeling and incentive programs.

Northwest Energy Efficiency Alliance commissioned a study to delineate the characteristics of 18 dimming systems as part of its Luminaire Level Lighting Control initiative. In theory, adjusting the light level by dimming 15 percent at the control station will have that intended effect (light level or power consumption reduction) at the light source or driver. In practice, this rarely happens. The study found that each ballast’s response to a linear control signal input varied and was not linear. The variances ranged from minor (plus/minus 2 percent) to significant (plus/minus 18 percent). This has implications for utilities in forecasting the anticipated energy savings of a lighting control system.

The data center market continues to evolve at a rapid rate. Embedded data spaces are consolidating as rack density increases and information technology performance increases. Physical data center footprints are shrinking and growing business demands are putting more pressure on data center managers to deliver more, with fewer resources. At the same time, decision-making related to energy efficiency is complex; decisions occur at the speed of business requirements, the level of sophistication in the market varies dramatically, and the subject matter is highly technical. The findings from this research suggest that the following three market interventions have the highest success potential related to energy efficiency in embedded data centers: exploration and refinement of prescriptive measures, including efficient servers, utilization and/or virtualization, and efficient uninterruptible power supplies; a website “clearinghouse” specific to embedded data centers that would serve as an unbiased source of information related to energy efficiency and function as a gateway to link customers to contractors and utility incentives; and promotion of efficient colocation data centers (or “Cloud Services”) and incentivized movement of the data center function from the smaller and less efficient data center to the larger and more efficient colocation data center. Other avenues for market intervention include aligning with existing initiatives, such as NEEA’s commercial sector efforts. NEEA’s current position is to encourage utilities to address this load by either custom measures and or targeted measure programs.

This report provides data and conclusions about the actual performance of different types of ventilation systems as installed and operated in relatively airtight homes. Overall, this study found that total ventilation is not a determining factor in ventilation effectiveness. A key factor is the ventilation delivered to each occupied space. This is coupled with a number of other influencing factors such as house size, occupant density, airtightness, and the presence of a whole house air circulation system such as central forced air. Other factors that affect ventilation performance include humidity, home occupant education and type of heating system.
