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.

Thermal insulation is an important part of commercial roofing assemblies. The aim of this article is to examine the factors influencing the thermal resistance, known as R-value of polyiso. The prediction of long term R-value and the influence of climate, i.e. temperature, have been of significant interest over the past few decades as building energy budgets have increased in importance. Recent discussions as to what R-value the designer should use and the importance of ambient temperature are reviewed and discussed.
