Passive House
After successfully completing and selling the first "Passive House" in the Washington Metropolitan area, O'Neill Development, along with architect partner David Peabody, will begin construction on their second and third passive houses. One will be built in Rockville for an out of town client and the other will be a modular passive house under contract with the Housing Initiatives Partnership; for sale to a low/moderate income buyer in Prince Georges County. "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.
