Longmont ZNE Home: Near Zero Net Energy for 5% More

Download Profile (PDF)

The Hainlines’ custom home, overseen by expert on-site Project Manager, Jim Pendergast, is due to be completed in August and is projected to achieve a HERS 9 rating.  The Hainlines came to Ecofutures at the onset, relying on our expertise to provide them with the best integrated design team possible, and thus only 5% of the overall construction budget had to be allocated to achieve Boulder County’s BuildSmart-mandated HERS 10 or better.   That 5% included building envelope upgrades such as walls with interior thermal breaks, closed cell spray-in-place foam, and double dry wall, as well as high-performance windows, and a large sun space 3 feet deep that acts as a solar air collector for space heating. Solar thermal and solar electric renewable energy systems were also included in that 5%.

Currently, Jim is having his crew finish up exterior framing and roofing, as well as start on paint and stucco.  Throughout the interior, the HVAC and electrical phases are beginning and the glass for the innovative sunspace was just installed.
