SFTool Blog

Welcome to the SFTool Blog. The Sustainable Facilities Tool (sftool.gov) helps you do more than learn about high-performance buildings and purchasing. SFTool helps you put this knowledge into practice, and assemble the people you need to help you get stuff done.

We’ve decided to share some of our experiences while developing SFTool. We’ll talk about interactions with the building community, challenges we’ve overcome designing the site, and other stories about putting high-performance ideas into practice.

Note: The SFTool blog may contain links to websites of public and private organizations, as well as references to specific products used in development. A link or mention anywhere on SFTool is not an endorsement of the views, products, or services provided by the mentioned resource or product.

Circadian Light

In its December newsletter, the Office of Federal High-Performance Green Buildings highlighted some of its recent work on circadian light and its effects on office dwellers. Circadian rhythms are defined as "physiological processes that occur in the body approximately every 24-hours." The most well-known of these is the wake/sleep cycle we all experience with the sun every day. The light we see in the morning and throughout the day tell our bodies it's time to be awake and alert. The darkness of night encourages sleep. Here are a few excerpts from the newsletter:
  • The average person spends only 17 out of 169 hours each week outside in the sun.
  • Receiving more circadian light during the day results in better sleep and more positive moods.
  • The design of a building significantly affects the ability of its occupants to get sufficient daylight exposure.
You should definitely check out the rest of the newsletter; it's a quick, interesting read. But if you're looking for even more, follow the links within the newsletter, and check out our resources on daylighting and its effects on occupant health. Go get some sun!
