The Passive House standard promises outstanding indoor comfort and energy efficiency. To meet this requirement, though, vendors who can offer premium, energy-efficient building materials and components must be carefully chosen.
When selecting passive house suppliers, bear the following points in mind:
Knowledge and Proficiency
Seek out vendors who have a history of completing Passive House projects. They must be knowledgeable about the building envelope specifications, Passive House principles, and your project's particular requirements. Prior experience working with certified Passive House designers and advisors can be beneficial.
Product Selection and Excellence
Make sure your suppliers provide a wide selection of goods that satisfy the exacting specifications of the Passive House standard. These consist of energy-efficient windows and doors, ventilation systems, heating and cooling equipment, airtightness solutions, and high-performance insulating materials. Quality and durability must be given top priority to guarantee long-term performance and energy savings.
Compliance and Certification
Make sure the products from your suppliers are certified and meet all applicable construction codes and requirements. Seek certifications that attest to the items' compliance with the Passive House standard's particular requirements. This certification guarantees that the goods have undergone extensive testing and fulfil the necessary performance standards.
Technical Assistance and Instruction
A trustworthy provider should offer first-rate technical assistance and training to guarantee the correct installation and upkeep of their equipment. This entails having access to installation instructions, technical documentation, and on-site assistance from qualified experts. Training might also benefit contractors and installers by reducing mistakes and improving the building's energy efficiency.
Logistics and Local Availability
Take into account your suppliers' geographic location and punctuality of delivery. Advantages from local suppliers could include simpler collaboration with the building crew, faster response times, and better logistics. But it's crucial to strike a balance between the need for specialised, high-quality products and local availability.
By carefully weighing these elements, you can choose vendors who can assist you in reaching the lofty objectives of your Passive House project. A carefully considered supply chain will guarantee maximum energy efficiency, comfort, and longevity, all of which will contribute to the overall success of your project.

The 68-unit, 8 story HANAC Corona Senior Residence was constructed in Corona, N.Y. for providing safe and affordable housing system through cutting edge sustainable building design to low-income seniors.
The project aimed at achieving 75% - 90% energy savings compared to the existing buildings, which is a prerequisite for obtaining the Passive House Institute (PHI) certificate.PHI developed the Passive House certification system, a high performance building standard, in 1990 which focuses on building’s passive measures like insulation, air tightness and heat recovery for providing superior indoor air quality, while reducing the energy bills to the highest possible extent.In October 2020, HANAC Corona Senior Residence was fully approved as a Passive House certified building with the help of New York Engineers, a NY based MEP engineering firm.
This made HANAC as the 1st affordable housing project in NYC that meets the PHI standards.
NY Engineers provided mechanical, electrical, plumping and fire protection designs for achieving superior energy efficiency and indoor air quality.Requirements For a building to get the Passive House certification, it must meet several performance requirements.
The following table represents the building quality requirements and the associated performance levels of each.
