Impacts of offfice plug load reduction strategies
2016 | Seventhwave, along with the Center for Energy and Environment and LHB, conducted a field research study to demonstrate and measure savings from potential plug load reduction strategies in office buildings. We also characterized the types of devices and baseline usage in those offices, and...
Energy savings from implementing and commissioning demand control ventilation
2015 | Demand control ventilation (DCV) systems use sensors—generally either CO2 or occupancy sensors—to estimate the actual number of people in an area and supply only as much ventilation air as is needed at a given time. DCV has the potential to save a substantial portion of building...

2015 | Prepared by Cool Choices and Seventhwave (formerly Energy Center of Wisconsin).
Performance of water-source variable refrigerant flow: measurement and verification of two installed systems
2015 | Variable Refrigerant Flow (VRF) systems have developed into a promising emerging technology. While popular in some places in the world, these systems are quite new to the upper Midwest. The systems are an innovative version of a simple split system air conditioner that utilizes variable...
Implement and commission demand control ventilation to capture significant energy savings
2015 | Summary of findings from a field study of DCV system performance.
Application of air source variable refrigerant flow in cold climates: a white paper
2015 | This white paper outlines the optimal control strategies for designing and operating air source VRF systems in cold climates.
Adjusting lighting levels in commercial buildings
2015 | Summary of findings from task tuning research.
Adjusting lighting levels in commercial buildings: energy savings from institutional tuning
2015 | 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.
Task tuning has the potential to save energy...
