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.
Designing for Moisture Durability and Energy Efficiency, Part 2 Part 1 of our discussion of Designing for Moisture Durability and Energy Efficiency explored the driving forces that result in the increasing interactive complexity and tight coupling of roofs and other building systems in modern green buildings. Part 1 also provided an overview of the various project life-cycle phases and compared the top green rating system's scope to address or not address moisture durability in those phases.
How Designers & Super Crews Can Maximize Roofing EfficiencyThis case study looked at how a roof system designer, working with an expert crew, can both increase roofing efficiency and offer performance advantages to the building owner.
Ventilation for steep-slope roof assemblies is often misunderstood. One must not only understand the code requirements, but be able to translate them into real-world installations. Building codes have requirements for ventilation of steep-slope attics and enclosed rafter spaces. Balanced ventilation — nearly equal amounts of intake and exhaust — typcially provides efficient ventilation. Transitions between low-slope and steep-slope roof areas require more distinct intake and exhaust details than traditional eaves/soffits and ridges.
