The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
Destratification is the reverse of the natural process of thermal stratification, which is the layering of differing (typically increasing) air temperatures from floor to ceiling. Stratification is caused by hot air rising up to the ceiling or roof space because it is lighter than the surrounding cooler air.
When radiant solar energy strikes a roof, heating the roofing material (shingles, tiles or roofing sheets) and roof sheathing by conduction, it causes the underside of the roof surface and the roof framing to radiate heat downward through the roof space (attic / ceiling cavity) toward the attic floor / upper ceiling surface.
A dropped ceiling is a secondary ceiling, hung below the main (structural) ceiling. It may also be referred to as a drop ceiling, T-bar ceiling, false ceiling, suspended ceiling, grid ceiling, drop in ceiling, drop out ceiling, or ceiling tiles and is a staple of modern construction and architecture in both residential and commercial applications.
Earlier this week, temperatures across the Midwest and the Northeast felt more like fall than late summer, as many people woke up to chilly mornings. In the coolest spots on Wednesday and Thursday ...
The climate pattern – marked by a natural cooling of seawater in the tropical Pacific Ocean – is one of the main drivers of weather in the United States, especially during the late fall ...
The vibrancy of fall foliage is significantly influenced by the weather during the summer and early fall. One of the key factors is consistent rainfall throughout the summer.
A shingle roof in Zakopane, Poland. With an area of 6000 m 2 (1½ acres), it was one of the largest wooden shingle roofs in Europe. A roof’s shingles are a roof covering consisting of individual overlapping elements. These elements are typically flat, rectangular shapes laid in courses from the bottom edge of the roof up, with each successive ...
