“…The performance improvements have been validated with field tests and case studies supported by DOE's emerging technologies team. The approaches and results of these field tests and case studies are described and summarized in previous reports Cort 2013) and a high-level summary of these activities is provided in Table 1.…”

“…A number of promising market transformation pathways were identified, including existing weatherization assistance programs, utility energy-efficiency incentive programs, federally sponsored energy-efficiency retrofit programs, standards and rating organizations, and federal building energy-efficiency mandates and programs. This FY 2014 program plan is informed by many of the findings of the 2013 market assessment (Cort 2013). The region where low-e storm windows are recommended will be larger than shown for homes using propane or electrical resistance heating, or those that have particularly leaky windows.…”

“…Although the cost and performance attributes of low-e storm windows set the stage for wide-scale market success, some significant barriers to deployment have been noted based on early experience in the market, as documented in the 2013 Pacific Northwest National Laboratory (PNNL) report, Low-E Storm Windows: Market Assessment and Pathways to Market Transformation (Cort 2013). …”

“…Most storm window manufacturers also manufacture prime windows. Some in the industry have noted that the profit margin on prime window replacement is greater than that for storm windows; thus, the majority of manufacturers do not have a great incentive to advocate for storm windows (Cort 2013). Instead they classify them as a secondary product, available on a customized basis for special orders only.…”

“…There is a significant opportunity to improve the thermal envelope of today's homes by upgrading the performance of existing windows. In fact, DOE estimates that 42% (47.2 million) of U.S. homes have single-pane windows (DOE 2009), and based on DOE and industry shipment data, it has been estimated that an additional 46 million homes have double-pane windows with clear glass but not low-e glass (Cort 2013;DOE 2009). Complete window replacement can be expensive and occurs in only an estimated 2% of homes each year (AERC 2017).…”

Heat transfer through windows accounts for a significant percentage of a building's energy use and adds substantially to the peak cooling load of a home. Window covering manufacturers currently offer highefficiency insulated shades and motorized shading devices for certain product lines, but this automation is typically marketed as a convenience and security feature for the homeowner and often does not include energy-optimized control algorithms or dynamic and responsive features. This report describes the experimental design and results of testing the energy performance of Hunter Douglas double-cell cellular shades under various control schemes in the Pacific Northwest National Laboratory's (PNNL) Lab Homes. The results of both heating and cooling season experiments are presented. Tests were designed to assess the heating, ventilation, and air conditioning (HVAC) savings resulting from the thermal insulating properties as well as the automated and dynamic control strategies of shading devices. Control schemes tested included common "connected home" strategies where controls were integrated and coordinated between the window shading device, building thermostats, and external sensors.Experiments were specifically designed to examine persistence of savings with dynamic and potentially automated operation. To examine energy use and savings potential under typical use operational settings, a typical use scenario was developed based on previous residential behavioral research sponsored by the U.S. Department of Energy (DOE). The report also includes results from testing designed to examine the benefits (in terms of comfort, energy savings, and responsiveness to control) of coordinating the operation of cellular shades with HVAC control as a demand-response measure. Testing was conducted during both the 2017 and 2018 cooling and heating seasons.Some of the key findings for the cooling season are:• High-efficiency cellular shades have significant energy-saving potential during the summer cooling season (25% HVAC savings), but this savings decreases considerably if the larger view windows of a home remain uncovered during the day, particularly if these are west-or south-facing windows.
