About Bright Lane Home
Bright Lane Home covers the technical and practical aspects of natural light in Italian residential architecture. The focus is on daylighting strategies — how windows, skylights, and glazing systems are designed and positioned to deliver useful daylight while managing solar heat gain and thermal loss.
The content draws on publicly available technical standards, including Italian building regulations (Decreto Legislativo 192/2005 and subsequent ministerial decrees), European standards for daylighting (EN 17037), and energy certification frameworks (APE).
All articles are written in an informational style. No commercial products or specific contractors are recommended. References to manufacturers are included only where they illustrate a technical point with publicly available specifications.
Topics Covered
Areas of focus
Facade Orientation
