Roofing plays an extremely important role in protecting the building from the elements, impacting energy efficiency, and contributing to the resilience goals of a building. In our Winter 2024 issue, we go over plenty of roofing aspects including lightning protection systems, architectural considerations for the roof, low-slope roofing and new insights challenging established roof color paradigms. Also, our latest CE Article allows you to earn 1 AIA LU/HSW; 1 IIBEC CEH; and 0.1 ICC CEU. We hope you enjoy this latest issue of Building Enclosure!
As communities across the nation grapple with escalating urban temperatures, some local municipalities and jurisdictions have mandated the color of roofs based on long-standing assumptions now brought into question by recent findings. The ERA research underscores that the impact of roof color on the UHI effect remains inconclusive, signaling a need for further exploration.
To efficiently future-proof the building envelope in light of the new climate reality, taking both into consideration is critical. One vital tool in this effort, though often overlooked, is air and water-resistive barriers (AWBs).
A single lightning strike is hotter than the surface of the sun and contains over 1 million volts of electricity. When this immense energy hits a structure, the power surges through the pipes, building structure, and electrical infrastructure. These damages can be avoided with the proper design and installation of a lightning protection system.
This article will illuminate a few critical design considerations, including substrate selection; use of proper joining methods, flashings, solder, and sealants; natural weathering and other finishes; and staining and corrosion control and prevention.
Although both wet-bulb globe temperature and Heat Index take into consideration dry-bulb temperature and relative humidity, Heat Index is calculated specifically for outdoor shaded areas and does not consider conductive heat transfer from wind speed or the heat stress added by direct sun exposure.
We sat down with PIMA president Justin Koscher to discuss the role of polyiso insulation in energy-efficient building construction and how the industry can further efforts to increase building energy efficiency and decarbonize.
Section 1507.2.9.3 Drip edge. Provide drip edge at eaves and gables of shingle roofs. Overlap to be a minimum of 2 inches (51 mm). Eave drip edges shall extend 0.25 inch (6.4 mm) below sheathing and extend back on the roof a minimum of 2 inches (51 mm).
