Glass Coolness

Windows are as old as buildings, the word itself derived from the ancient Norse language in times when Vikings raided North Europe. How to design a window? How should an architectural glass be chosen?  Vikings are long gone, and we found the knowledge remains common among architects in the North Europe, but has not spread much ever since, judging by some familiar examples. Nowhere else so much could be wasted by so few: the glazing is the most advanced and the most expensive part of many facades; therefore, it warrants a good, more than a skin-deep design.

In this article, titled “When You Need a Window – Solar Design” Kaz attempts to shed some light on two elementary aspects of glass engineering: visible light and solar transmittance. Their combination is called  the coolness factor and happens to be the the most important solar glass benchmark and part of the historical quest to bring the natural light deeper into the buildings while avoiding perimeter discomfort.
