Daylighting information previously included as a fact sheet has been updated and posted as a web page by the American Architectural Manufacturers Association (AAMA). This daylighting-focused web page focused on daylighting and energy savings addresses key differences between fenestration products installed primarily vertically (windows, doors, curtain walls and storefronts) and those installed primarily overhead [skylights, roof windows and tubular daylighting devices (TDDs)] and their relation to daylighting and energy savings.

"It was important to us that this section of the site be seen as an authoritative resource on how daylighting products can lower energy costs and conserve resources," said Chris Magnuson, chairman and president of Wasco, and chair of AAMA's Skylight/Sloped Glazing Marketing Committee, which led efforts to develop the web page. "We're confident it will be useful to homeowners, industry professionals and more."

Further considerations for proper daylighting as covered on the web page are health, comfort, solar tuning and other design aspects. AAMA encourages companies to provide these web pages to their customer service representatives to serve as a third-party resource for commonly asked questions.
