Green Building United stands at the forefront of a movement to reshape how buildings are designed, constructed, and operated across the greater Philadelphia region, Lehigh Valley, and the State of Delaware. As a nonprofit 501(c)(3) organization and a chapter of the U.S. Green Building Council, this member-driven organization works to advance an equitable transition to […]
Gehrung+Graham is an architecture and consulting firm based in Charlottesville, Virginia, that has built its practice around a compelling mission: deliver buildings that produce more energy than they consume. The firm specializes in creating high-performance architecture measured by energy efficiency, client satisfaction, and excellence in design. By integrating certified Passive House methods into both new
Passive House construction demands more than a checklist of performance targets. It requires a coordinated team where architects, engineers, and sustainability experts work together from the earliest design stages. EXP, a global engineering, architecture, design, and consulting firm, has positioned itself as a key partner in this effort. Listed on the Passive House Accelerator partner
When architects and builders set out to meet the rigorous Passive House standard, they quickly discover that ordinary windows simply will not suffice. The building envelope in a Passive House must achieve extraordinary levels of airtightness, thermal insulation, and solar heat gain control and windows represent both the greatest challenge and the greatest opportunity within
The demand for buildings that consume less energy, offer superior comfort, and stand up to extreme weather has pushed the construction industry toward new methods. Among the most effective approaches is panelized passive house construction, where wall, roof, and floor panels are precision-manufactured in a factory and assembled on site. This technique combines the airtightness
The demand for energy-efficient housing has never been higher. Homeowners and builders alike are searching for construction methods that deliver superior performance, lower utility bills, and a reduced environmental footprint. One of the most rigorous building energy standards in the world, the Passive House standard, offers a clear path toward these goals. Companies like EcoCraft
Passive house construction represents the gold standard for energy efficient building, reducing heating and cooling energy by up to 90 percent compared to conventional structures. While the principles are well documented, the practical execution requires contractors with specialized knowledge and precision. Companies listed as partners on the Passive House Accelerator platform, such as Durfeld Constructors
Behind every certified passive house building stands a team of specialized engineering consultants who translate energy performance goals into workable technical systems. While architects and builders often receive credit for striking passive house projects, the mechanical, electrical, plumbing, and fire protection engineers who design the building’s core systems play an equally decisive role. Firms such
High-performance building design demands more than choosing efficient equipment or thick insulation. It requires an integrated approach where mechanical, electrical, plumbing, and enclosure systems work together from the very first planning sessions. DataBased+, the research-driven human-centered design studio of dbHMS, has built a reputation around exactly this kind of collaborative practice. Founded in 2002 on
The construction industry stands at a pivotal moment where sustainability is no longer a niche aspiration but a practical necessity. Among the most promising developments in green building is the use of natural plant-based materials to achieve passive house standards. Companies like Build With Nature, a design/build and consultancy firm based in New England, demonstrate
