Data center
Research | December 20, 2018 by Scott Schuetter
Small embedded data centers (SEDCs) are one of the fastest growing end uses of electrical energy in commercial buildings and are estimated to account for nearly one percent of the total electricity use in the U.S. By some accounts, as much as one third of this usage is unnecessary, but this premise has not been addressed by Focus on Energy programs or by most device manufacturers.

On behalf of Focus on Energy’s Environmental and Economic Research and Development Program (EERD), Seventhwave collected information from Wisconsin businesses on their light levels and associated lighting system characteristics. This information will help Focus on Energy address savings opportunities from optimizing light levels by identifying appropriate program offerings and resources. More
daylight controls
Research | December 20, 2018 by Scott Hackel and Scott Schuetter
Proper commissioning can lead to energy savings—often 60% or more Daylighting control, or daylight harvesting, has become a common energy savings strategy in many sustainable building projects, but several barriers still prevent successful implementation of this strategy in mainstream construction. Considerable effort is expended in the architectural and lighting design of daylighting controls, with actual execution being an afterthought. More
VRF
Research | December 20, 2018 by Scott Hackel and Scott Schuetter
Application of air source variable refrigerant flow in cold climates Variable refrigerant flow (VRF) systems use variable speed, split heat pumps to provide space heating and cooling to a building's conditioned areas. Air source VRF systems perform best in moderate climates, as they typically lose capacity and efficiency at low ambient temperatures—or moderately low wet bulb temperatures where defrost is required—and may be supplemented by an additional heat source.

Task tuning can lead to energy savings without loss of occupant comfort. Task tuning is one form of lighting control that can be used in commercial buildings to save energy. It involves dimming lights in a space so that the average illuminance at the working plane is appropriate for the type of use in that space. More
RTU
Research | December 19, 2018 by Scott Schuetter
RTUs are used in more than one third of U.S. commercial buildings, the highest of any cooling equipment type. Why? They are reliable and have a low capital cost, as well as established service and distribution networks. There is anecdotal evidence, however, that these systems operate inefficiently. To validate or refute this evidence, we conducted a multi-level field study sponsored by Minnesota Department of Commerce, Division of Energy Resources. Resources: More

The goal of this project was to examine the impacts of climate change on the energy use and operating costs at NASA's John C. Stennis Space Center (SSC), located in southern Mississippi. Specifically, we quantified the expected impacts on future energy consumption, peak energy demand and energy costs due to climate change at the SSC facility. We also developed potential adaptation approaches through the application of energy efficiency technologies. ADDITIONAL RESOURCES More
