Outreach

Throughout our half-century of windows and energy-efficiency research, we've been firmly dedicated to supporting and informing industry; providing important research and data to policymakers; providing better windows, glazing and envelopes in the U.S. and worldwide; and pushing forth the mission of the Department of Energy.

Bringing Research into Practice

Through collaboration and scientific advancement, the Windows Group has made significant strides in enabling the development of energy-efficient window technologies like low-emissivity window coating, leading industry software tools, and dynamically tinting "smart windows." 

Every year, Americans reduce energy bills by billions thanks to a low-emissivity (low-e) window coating that Berkeley Lab developed with industry. Once a novelty, it is now the market standard for efficient windows. 

Read some of our success stories: 

• Radiance, the preeminent lighting simulation software 
• Low-e Windows, saving consumers billions in energy costs
• WINDOW & THERM, industry-standard software guiding energy professionals and policy 
• Smart windows, the culmination of decades of research advancing global technology

DIY Affordable Shading Guidance during Extreme Heat

This study shows how you can easily and affordably shade your windows to keep your home from getting too hot on sunny days. This phenomenon (what researchers call “solar heat gain”) can threaten occupant comfort and safety, especially during heatwaves. Still, many homes lack adequate protection. All of these solutions can be implemented inexpensively using common household items or items that can easily be purchased online. Additionally, you don’t need specialized tools or expertise to install them. Note that these are ideally temporary fixes, so households with sufficient means should still pursue permanent ones (e.g.,shades—preferably on the outside—or specialized windows or films). In their absence, the stopgap measures described below can help protect you and your loved ones during heatwaves and other exceptional events.

This handout, "DIY Affordable Window Shading" (PDF) provides the DIY/affordable shading options for keeping heat out in extreme heat.
