DOE Seeks Feedback From Door and Window Manufacturers for Energy Star Version 7

After releasing its Energy Star Version 7.0 Window, Door and Skylight (WDS) Discussion Guide in early September, the U.S. Environmental Protection Agency (EPA) is now seeking stakeholder input.

In a webinar held Sept. 17 to further engage collaboration and discussion, EPA officials made it clear that their intention is not to catch anyone off guard with the proposed revisions and that there is still much to be discussed.

“Suffice it to say, the cake is not yet baked here,” said Doug Anderson, EPA Energy Star program manager during the webinar.

The webinar presentation summarized the information previously published in the Discussion Guide on the following topics:
• Background on the process for Energy Star specification revision;
• Assessment of the current Energy Star WDS market;
• Proposed methodologies for evaluating a potential revised specification; and
• Additional issues that EPA plans to consider in a potential specification revision

According to information published in the guide, among the reasons EPA cites as cause for revisions is an abundance of market share for Energy-Star-certified products. The guide also suggests, “Recent developments in energy codes and other product specifications may surpass the current Energy Star specification levels.” Despite preliminary indicators, EPA officials say they “must still conduct additional analyses before deciding to propose to revise the specification.”

Questions for stakeholders are included in each section of the guide, which the EPA is hoping will facilitate collaboration. There are 28 questions in total, including such things as:
• What are good sources for data on the subjects being discussed in each section?
• What factors should the EPA consider?
• How should certain processes be revised to better evaluate performance? and
• What impact would potential changes have on consumers and partners?

Specific information can be found in the guide.

The EPA is asking stakeholders to review the Discussion Guide and formal comments were due by October 4, 2019. Officials say the are planning to release the organization’s response to comments by the fourth quarter of 2019 or first quarter of 2020 and will later release the criteria analysis report around the second quarter of 2020.

Ubiquitous Energy Researches Transparent Solar Window Technology

Ubiquitous Energy has begun work on a new research and testing program for the company’s ClearView Power (CVP) technology, a transparent solar coating that can be applied to the vertical surfaces of buildings, turning traditional windows into electricity-generating windows.

The research program is being funded partially by a $3 million grant awarded from the California Energy Commission (BRIDGE). Ubiquitous will be working with Lawrence Berkeley National Laboratory and its Windows Group, experts in the testing of windows and window-coating performance. The research and testing program with the lab will focus on the testing and validation of the performance of CVP.

“We are working to accelerate the development and testing of CVP so that it can be used by the glass and window industry for window energy-efficiency,” says Ubiquitous Energy CTO Miles Barr. “This … patent-protected technology will provide a truly transparent energy harvesting solution to the building integrated photovoltaic market, enabling zero net energy buildings and beyond.”
