The Envelope

Partner Spotlight: HFH of Catawba Valley

Habitat for Humanity of Catawba Valley was recognized in September by the U.S. Department of Energy with the 2016 Housing Innovation Award which showcases homes that are the very best in innovation on the path to being zero energy ready.

This winning 1,340 square foot one-story home includes four bedrooms and two baths. Construction details include high performance insulation, high-efficiency HVAC, high-efficiency appliances, advanced lighting, and technology for energy and water savings. The homeowner sums it up best:

The thing that amazes me the most about this house is the fact that we have so much more space, but we pay a fraction of the cost in utilities. Before we moved, we were living in an 800-square-foot residence and often paying over $200-$225 for utilities. Here, we have more space (over 1,300 square feet), but our utility bill is less than $100.

Keeping the Crawl Space Dry During Construction

Managing moisture in crawl spaces during the construction process is always a challenge.

Advanced Energy has developed a tip sheet to help builders implement strategies to reduce the potential for mold growth during construction. The document Managing Moisture in Crawl Spaces During Construction is available for download from the SystemVision Tools website.

SystemVision Air Tightness Study

Air sealing sheathing and bottom plates with caulk.

While new SystemVision standards were rolling out last year, Advanced Energy was hard at work sorting through data and surveying builders in the SystemVision Program to answer the question:

What architectural features and building practices lead to tighter SystemVision homes? 

After interviewing builders, studying floor plans, and running countless statistical models on close to 1,000 homes, we found practices that statistically lead to tighter homes:

Simple homes with fewer stories, windows and corners.

  1. Fewer can lights.
  2. Air sealing with caulk rather than foam.
  3. Sealing the double top plates together.
  4. Sealing the exterior sheathing to the bottom plate.
  5. Sealing the top plate to drywall after the ceiling drywall is hung.

If you are struggling with the new air tightness standard, then these six tips may be a good starting point.  The Air Sealing Checklist featured on the SystemVision Tools website offers practical guidance and images for how to achieve better air sealing

If you are already meeting air tightness targets on a consistent basis, keep up the great work and don’t change what you are doing.
