Congratulations to our sister company, Hugh Lofting Timber Framing, Inc: Hugh Lofting Timber Framing Gains Passive House Certification Company recognized by Passive House Institute US as one of only seven Certified PHIUS Builders in Pennsylvania; passive house project underway in West Chester, Pa. Hugh Lofting Timber Framing, Inc. has been recognized by the Passive House Institute US as a PHIUS Certified Builder, and has a passive house under construction in West Chester, Pa. The PHIUS designation means the company understands passive house principles, has mastered craftsmanship techniques specific to passive houses, and can meet challenges specific to the North American climate. A passive house achieves overall energy savings of 60-70 percent through super-insulation and airtight building envelopes, highly efficient HVAC systems or energy recovery ventilation, high-performance windows, and moisture control. Passive construction does not employ active technologies such as photovoltaics, and can thereby be less expensive when the principles are used alone. According to the U.S. Department of Energy’s Challenge Home program, passive and active design principles used together can be the best direction toward Net Zero houses. “Hugh Lofting Timber Framing has long been committed to energy and design efficiency,” said founder Hugh Lofting. “The firm has embraced the use of FSC-certified timbers, reclaimed and salvaged woods, and environmentally aware finishes. Attaining PHIUS certification demonstrates to our clients and colleagues that we remain focused on long-lasting, energy-efficient homes and buildings.” A passive house is heated primarily by passive solar gain and by internal gains from people and electrical equipment. Energy loss is minimized through super-insulation and an airtight building envelope. Shading and window orientation help to avoid heat gain, which limits cooling loads. Superior air quality and comfort are accomplished with a heat/energy recovery ventilator. PHIUS Certified Builders have passed a four-day training program and a written exam. There are 45 PHIUS Certified Builders in the U.S. Hugh Lofting Timber Framing, Inc. is one of seven in Pennsylvania. Hugh Lofting Timber Framing presently has a passive house in construction in West Chester, Pa. To find out more on this project, visit the owner’s blog The Winding Path to a Simple Home. The 2,000-square-foot residence includes high-performance Intus windows and a super-insulated structure. Completion is planned for early 2014. The house will stand as a local example of passive house techniques blended with timber frame craftsmanship. About Passive House Institute US Passive House Institute US is a registered 501(c)3.
