Passive House construction is my personal favorite form of green building. The reasoning is simple — it offers maximum energy savings with the lowest upfront premium. Building or renovating to the Passive House standard is well proven throughout the world and it has developed a solid framework in the United States.
Through my work with UltimateAir, I have had the honor to work on many Passive projects. These include multi-family developments, University Dormitories, residential homes, and commercial buildings. I have personally witnessed these buildings obtain a 60%-80% reduction in their energy use. While also offering residents healthier interior air, comfortable living environments, and superior building longevity.
The idea behind Passive House is actually quite simple. Heavily insulate the walls, foundation, and roof. Air seal the home to decrease energy loss and improve comfort. Eliminate “thermal bridging” by incorporating a non-breaking blanket of insulation. Minimize the size of the heating/cooling system for maximum efficiency. Incorporate an energy recovery ventilator to continuously flush the home with fresh air.
Most people I talk to about Passive, automatically jump to the conclusion that Passive House is not affordable. They assume that the cost of a low energy, healthy, and comfortable home is just far out of reach. In my experience this is not the case at all!
When designing the project upfront with Passive House aspects in mind….the added cost over standard construction tends to fall between 1%-8% over a standard “code” construction project. When you factor in an electric bill that is possibly 70% lower — this upfront premium is usually profitable or at a minimum…break even.
The key to designing a high performance home for little extra cost is to accept the Passive House standard as a design principle from the beginning. Do not design a house and THEN try to add Passive House features. Rather, design a Passive House from the beginning and within the constraints of your budget.
Customer 1: “I need a 4 bedroom house, with an open concept living/dining/kitchen, lots of natural light, and beautiful kitchen countertops. My budget is $180,000.”
This can be done!

It’s all about accepting high performance into your design criteria and moving forward accordingly. Just like any other aspect of building a home within a budget…
Working with Passive House builders and architects for the last 6 years has allowed me to see how the market is changing and growing. In 2018, we saw the largest amount of growth coming from New York.
The City of new York created a goal of reaching an 80% carbon reduction from 2005 levels by 2050. Buildings account for 75% of the energy used in NYC and therefore efficient buildings will be key to meeting this goal. NYC Mayor De Blasio has even pointed to the Passive House standard as one of the few energy standards capable of delivering the needed results.
As the NYC construction market continues to adopt Passive House into its future, they will require a roadmap for tradespeople education, product suppliers, architect education, and building operation. New York can look to the success of Brussels, Belgium to help understand how to make the shift. Brussels began by awarding $36 million to a hundreds of energy efficient projects and by 2010 they created a version of the PH standard for all public works projects. By 2015, all new or heavily renovated project must meet Brussel’s passive criteria.
List of my favorite New York organizations who are leading the charge!
- NYSERDA (Trade Organization)
- The New York State Energy Research and Development Authority has always pushed for energy efficiency and the use of renewable energy sources. They are a fantastic resource for advancing the innovative solutions needed to improve the New York building culture, economy, and environment.

- The Bluestone Organization (Developer)
- Their name has always been a staple in the New York housing sector; however, now the Bluestone Organization has been helping to lead the way with their recent Beach Green project in Roackaway, NY. They are a third generation family business that was founded in 1927.

I would recommend talking with Tom King, who is a certified Passive House Architect and experienced practitioner.
