Passive House

Logo: Passive House Institute USO’Neill Development, along with Architect David Peabody, have designed and built the first “Passive House” in the Washington Metropolitan area (and the 22nd in this country) as well as the first modular passive house in this area. “Passive” construction involves a super insulated structure with constantly re-circulating fresh air and even temperatures throughout. A PH home uses roughly 90% less heating and cooling energy than the average home. It is designed as an integrated system, with site, energy, ventilation, air quality, humidity, health and comfort all taken into account. The images that follow are examples of our passive house construction.
