Wind Design for Roofing Systems: Tips and Tools for Success
As the architect on a project that involves a roof, whether a new construction or a reroof, the building owner relies on you to specify the roofing system that will perform well, stay within their budget, and comply with local building codes. As part of this process, wind design is integral to success. The challenge is choosing the right path to code compliance.

How will ASCE 7-16 affect the low-slope roofing industry? A Tale of Two Buildings
A common question being asked in the roofing industry is whether or not the 2016 version of ASCE 7 is going to increase the design wind pressures acting on a building. The answer is "yes" in many cases. So, the follow up question is "by how much?" And, that leads to the next question, "how much more capacity will roof systems be required to have when wind design follows ASCE 7-16?"

The Physics of Thermal Inertia in Low-Slope Roof Design
What are the key material properties? In a previous article the use of thermal inertia to slow down heat flux through a roof assembly was discussed. In buildings where air conditioning costs dominate and heating use is relatively low, higher thermal inertia assemblies can potentially improve energy efficiency. This is particularly the case of buildings such as offices that are only occupied during daylight hours. Thermal inertia could delay the transmission of heat into a building towards the end of the day, increasing thermal comfort and allowing facility managers to reduce cooling during the day.
