High Standards for Ultra-low Energy Buildings
Passive House (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 buildings are very well insulated and virtually air tight, and require 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. The Passive House standard applies to all building types, including single and multi-family residences, mixed-use buildings, as well as commercial and office buildings.
An early leader in the Passive House movement in the United States, Green Hammer has been involved with the majority of certified Passive House commercial and residential buildings in the Pacific Northwest. Currently Green Hammer is design-building or consulting on nearly 200,000 square feet of Passive House buildings in the State of Oregon alone.
Green Hammer has several Certified Passive House Consultants (CPHCs) on staff:
