For decades, building conversations focused on finishes, floor plans, and mechanical systems. But today’s most critical performance decisions happen much earlier—at the building envelope.
“In the complex and multi-tiered process of building a new home, there are few decisions, aside from the geographic location and siting of the house, that will affect its performance more than the building envelope.” This from Green Builder magazine’s Editor-in-Chief launches a brand-new ebook, The Perfect Envelope.
The book explores how modern envelope systems are changing what high-performance construction looks like in practice. It pairs building science fundamentals with real-world case studies that show measurable gains in energy savings, durability, and occupant comfort.
“In my 30 years as an editor, tracking every type of wall system from ICFs to SIPs to parallel (lumber-framed) walls and straw bales, my takeaway is that almost any good system can deliver good performance, but not all systems are optimized to withstand the stress of natural disasters while also reducing energy waste and ongoing resource use,” Power says.
The good news, Power points out, is that the building envelope you choose as a builder or homebuyer is not an all or nothing decision. The book talks about combining two or more systems to get the ultimate envelope. In addition, Power details real-world case studies of homes and how they created perfect envelopes, including product specifications.
As climate risks rise and buyers increasingly prioritize performance and resilience, the building envelope is no longer a background decision—it’s the main event.
