Book excerpt: high Performance Enclosures : Design Guide for Institutional, Commercial and Industrial Buildings in Cold Climates provides guidance for architects and building enclosure engineers working to meet the growing need for buildings that have significantly lower operational energy consumption. John Straube addresses a range of practical questions about low energy building enclosures that save energy while simultaneously improving durability, comfort, and rain control: How much of an impact can the enclosure, massing, and orientation have? How much glazing is appropriate and what options are available? How much does thermal bridging matter and how can it be minimized at difficult structural details? How does one detail thick layers of continuous insulation outside of steel stud walls? Can layers of insulating sheathing reduce the risk of moisture damage?--COVER.
