Expanding Passive House Construction in Portland12.1.17
A pioneer of Oregon’s green building movement, Portland-based Green Hammer is a champion of green building standards that lead to longer-lasting, comfortable, energy-saving homes. As West Coast leaders join forces to fight climate change through a variety of tactics, Green Hammer will continue to work toward our goal of designing and building projects that produce as much or more energy than they consume.
At Green Hammer, we use a variety of green building standards to create homes that are restorative and regenerative, produce more energy than they consume, improve air quality, and reduce or eliminate the need for fossil fuels and toxic materials. Passive House design and construction (known as Passivhaus in Europe) is an advanced energy-efficiency standard that produces buildings with superior indoor air quality and thermal comfort while reducing required heating energy use.
Passive House construction generally produces buildings that are super insulated and virtually air tight, requiring minimal energy for heating and cooling. A typical Passive House building consumes 90% less heating and cooling energy and has 70% less overall energy consumption than a standard home. This is not just environmentally-friendly; it is an enormous asset to people who live and work in certified Passive House buildings, who benefit from decreased monthly utility bills.
The Passive House standard can be applied to any type of building and has been demonstrated in projects around the world. Green Hammer has helped design, develop and construct private homes, offices, multi-unit residential facilities, public buildings and commercial spaces that meet the Passive House standard. Examples of Green Hammer's Passive House construction in Portland and Passive House construction in Southern Oregon prove that a wide range of clients — from single-family homeowners to nonprofit organizations — can achieve high-performing buildings.
Green Hammer’s Certified Passive House Consultants (CPHCs) have completed numerous Green Hammer building projects in Portland and Oregon, and regularly consult on bigger projects, such as Orchards at Orenco, a Passive House construction project just outside of Portland, Oregon. As of this writing, it remains the nation’s largest multifamily project built to date to achieve Passive House certification.
