- Passivhaus Austria
|Vancouver, British Columbia
Um in Vancouver soziale Wohnbauten errichten zu können, müssen strenge Vorgaben erfüllt werden. Mit dem Passivhaus gelten diese Vorgaben als erfüllt. Des weiteren werden zertifizierte Passivhaus-Komponenten anerkannt und benötigen keine weitere Genehmigung durch kanadische Behörden: Green Buildings Policy for Rezoning
The city of Vancouver is looking first and foremost at removing barriers to Passive House Construction. A March 2015 letter from Vancouver to CanPHI-West issues such a clarification, in one instance accepting Passive House Institute window certification in lieu of NFRC or CSA tests.

Housing Design and Technical Guidelines for the City of Vancouver
The guidelines are for use when developers provide the City with Social Housing Units in return for density bonuses. The developer can build higher and get more market units if they provide 20% of the units as social housing.
Provide building forms and design that integrate the concepts and performance standards of the international Passive House standard, including optimized envelope design, optimised building massing and orientation, and the use of low demand equipment to reduce demand on fossil-fuel based energy and reduce greenhouse gas emissions. Mechanical and control systems should be designed to be as simple as possible to reduce maintenance costs and the need for specialized maintenance expertise. Designs should aim to achieve Passive House performance standards, including maximum heating demand of 15 kWh/m2-yr, heat load of 10 W/m2, cooling demand of 15kWh/m2-yr and primary energy demand of 120kWh/m2-yr.

Marin County, CA
The Marin County Board of Supervisors amended their building code in 2013 that included for the first time, on page 26, the following definitions:
"Passive House" means a building that meets the Passive House standards as developed by the Passive House Institute, Germany, providing cost effective energy efficiency, indoor air quality, and comfort through modeling using the PHPP energy-modeling program.
"PHPP means the "Passive House Planning Package", an energy-modeling program developed by the Passive House Institute, Germany, used in developing buildings to the Passive House Standard.
The new code encourages "green building" by authorizing the establishment of incentives for "green building compliance". It further notes "The applicable green building rating system shall be that which is most recently adopted by Build It Green or the U.S. Green Building Council or the Passive House Institute."
The Marin code can be found here.
New York City, NY
Mayor Bill de Blasio announced a policy One City: Built to Last in September 2014, to dramatically reduce greenhouse gas emissions from buildings city-wide by 2050. The policy states that New York City will look to "Passive House, carbon neutral, or 'zero net energy' strategies to inform the standards." In fact, Passive House is the only building energy efficiency standard noted in the plan – a tacit acknowledgment that other efficiency standards such as Energy Star and ASHRAE 90.1 fail to meet the imperative to reduce energy proportionate to mitigate climate change while producing resilient buildings that address the need for climate adaptation too.
Lower Manhattan, NYC, NY
Community Board One in downtown Manhattan, an important civic leader, incorporating the World Trade Center, Wall Street, City Hall and Chinatown areas, in December 2014 overwhelmingly passed a resolution in support of the International Passive House Standard. It reads in part: "...CB 1 supports the investigation of the implementation of the PH Standard for its potential application to new construction and renovation in our community. It also encourages the completion of a public project in Lower Manhattan to demonstrate a zero-net energy standard and cost saving potentials..."

The Building Codes Division issued a Statewide Code Interpretation in 2011 to the question "Does the Passive House Standard meet the intent of the Reach Code?" with the answer; "Yes, A building constructed to the Passive House Standard meets the energy efficiency requirements of the Reach Code."
See the interpretation here.
The Pennsylvania Housing Finance Agency (PHFA), formed by the Pennsylvania legislature to provide affordable homeownership, now provides incentives for Passive House compliance of multi-family buildings. Under heading of "Energy Efficiency Goals", Passive House is the only standard listed, reading in part; "The development meets/will meet Passive House Certification (nationally or internationally) for energy efficiency." Also, "All third party consultants must be Passive House certified."
San Francisco, CA
The San Francisco Planning Department issued new guidelines in October, 2014, giving preferential treatment to "green building" including Passive House, naming "Certified Passive House Certification or EnerPHIT Certification by the International Passive House Institute...".
