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.
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.

There is no easy answer to this question because there are so many factors that go into the price of a timber frame. For example, the timber species, complexity and even the type of joinery can greatly alter the price of a timber frame. These factors put the cost of a timber frame in the range of $50,000 to $500,000 and up. Typical residential customers usually spend around $75,000-$200,000 for an addition, $50,000-$250,000 for a barn, $9,000-$50,000 for a pergola and specialty projects can be anywhere on that spectrum.
Hugh Lofting Timber Framing built the heavy timber portion of this gorgeous poolside pavilion.
The heavy timbers are Douglas Fir and the roof decking is White Pine both stained with the same dark finish.
HLTF worked closely with Archer & Buchanan Architecture and Cherokee Construction on this project. For more information on this project, please contact our office.
This past month the HLTF crew raised a poolside pavilion in Gladwyne, PA.
The pre-assembled heavy timber roof truss system was flown into place by crane.
The pavilion was constructed from Douglas Fir timbers that have a dark stain applied to its surface.
The crew assembled the heavy timber roof system on the ground on the opposite side of the main house.
Once this was assembled they strapped the frame to fly level so that the crane could position the roof system into place.
Because of the job site layout, the timber frame had to be assembled on side of the house and then flown over the house to the poolside.
The frame was cautiously flown over the house and in between chimneys. This was no easy feat. There is also a fireplace right next to the pavilion that had to be maneuvered around.
The roof system sits atop steel posts. The crew had precisely cut the post slots in the shop so that the timbers fit exactly into place.
Eastern White Pine 2×6 roof decking was applied to the roof system to finish off the structure.

These past several weeks the crew at HLTF has been cutting out, pre-fitting and staining a new Douglas Fir, heavy timber framed pavilion. Here the crew is working on pre-fitting the pavilion in our shop.
This pavilion was raised today in Gladwyne, PA. Here the pavilion is being readied to be flown into place by the crane.
The pavilion had to be flown over the existing house and into place because of the site layout.
Once we have all the pictures, a full story on this Gladwyne Pavilion will be posted, so be sure to check back in.
