Today, PHI's standards are the most widely followed internationally, while Phius, the Passive House Institute US, separated from PHI in 2011 and sets different standards for North American buildings. The PHI standard applies the same criteria anywhere in the world; the PHIUS standard varies slightly according to location. With increasing concerns about climate change and urbanization, Passive House designs can now be found on every continent, including on Antarctica. With an airtight enclosure, continuous, balanced ventilation is absolutely critical to indoor air quality (IAQ).

When we go outside or travel to a cold climate in the winter, we put on a warm winter jacket, boots, hat, scarf, and gloves covering our entire bodies. Both standards require strict performance metrics to provide predictable results and incredible comfort, and both follow five core principles. Buildings have been built using passive solar building principles since before the 1970s. The US Department of Energy (DOE) and the Canadian government spearheaded experimentation with these principles. Phius-certified buildings go through a rigorous quality control process, ensuring safety for the environment and the building inhabitants. Creating your first Passive House can be fun and rewarding for designer and client alike.
Elimination of Thermal Bridges
This was discussed earlier for repeating thermal bridges in the general wall and roof assemblies, but Passive House designs also aim to be thermal-bridge-free when it comes to architectural interface details. These are parts of the building where different architectural features meet that require additional attention in construction. Examples include how a window is attached to the walls, how a wall meets a balcony, and how walls meet at corners, as shown in Figure 3. The way these building features connect and are designed can also introduce thermal bridging that’s not always easy to recognize. One important goal of the Passive House Standard is to minimize the total primary energy consumption.
How much does it cost to build a passive house?
Corners are a geometric thermal bridge because there is more exterior wall to draw heat out from the same interior wall area. The Phius Alliance, comprised of local U.S. chapters, is a leading proponent of code and other regulatory changes incorporating passive building standards. Phius has certified more than 11.2 million square feet of passive building projects. Michael Ingui is a partner at Baxt Ingui Architects and the founder of Passive House Accelerator.

Design and construction
Learn how you can build comfortable, healthy, cost-efficient buildings for a more resilient world. A passive house is built to much higher energy efficiency standards than a conventional building. This means that it requires less energy to heat or cool the building, reducing its environmental impact and long-term costs. Overhangs and canopies provide shade during the summer while letting sunlight penetrate the deep interior during the winter. An extensive storm water retention system, geothermal heating and cooling, super insulation and air-sealing, and Passive House quality triple-pane windows ensure the home’s long-term efficiency and comfort. Depending on the building's climate and layout, the airtight, super-insulated building envelope home with strategically placed high-performance windows built to the Passive House standard might not need any supplemental heating.
That is why a Serbian couple designed a home that heats itself entirely with sunlight rather than traditional heating methods. The only thing that betrays its status as a passive home is the greenhouse-like protrusion on the south side of the house. The Passivhaus creates an internal environment that is comfortable in both summer and winter.
• Daylighting + Solar Gain
Natural materials including Douglas fir timber framing, stained oak floors, Pennsylvania bluestone, and Quartzite counters glow in the sunlight and add warmth to the modern interiors. Imagine a home so energy efficient that it could be heated with just a hair dryer. If you’re working with a designer to build a brand-new home, it’s imperative to employ passive design, which reduces a house’s ecological footprint by using the local climate and landscape to its advantage.
How is a passive house different from a conventional building?
It sounds complicated and expensive, but when details and materials are all reviewed and simplified from the start, it is one of the least costly principles. Some homeowners might fear that a super-insulated and very airtight home might be a recipe for unhealthy interior air quality. Yes, it is true that once we have built an airtight, thermal bridge free thermos, we can no longer breathe through the cracks in the walls.
While the walls typically make up the largest area of a building’s façade, the glazing systems (windows and glazed doors) can play an even bigger role when it comes to contributing to space-heating energy. Due to their function (providing light and visibility), glazing systems cannot be insulated to the same degree as a wall, resulting in the windows being the weakest areas of the envelope in terms of heat-flow resistance. Therefore, it is very important that high-performance glazing systems, such as Passive House-certified windows, are used to reduce that heat flow as much as possible. The cost of building a passive house can vary widely depending on a number of factors, including the size and complexity of the building, local construction costs, and the specific technologies and materials used.
The process includes using modeling software to predict how all the specs will perform once built. Then during construction, all components are documented in measured photographs to prove the project is built as designed.

The project integrates exhibition, office, banquet, and recreational activity areas, presenting a unique encounter between people and space. Maria Videla-Juniel turned the primary bath into a sumptuous retreat with hues of soft blue and brown. Thibaut wall coverings and fabrics were used for the walls and windows, and the elegant shagreen-covered vanities are accented with gleaming fixtures by P.E.
The music room’s design incorporates futuristic elements and changing colors for a dynamic atmosphere. With a focus on lightness and translucency, the study area features light-emitting ceiling films and curved elements. For the design, One House, led by Fang Lei, combines modernism, avant-garde, and inclusiveness to create an environment that balances daily routines with future possibilities, enhancing the connection between work and life. By opting for materials that are renewable, nontoxic and locally sourced, homeowners can reduce the carbon footprint of their construction projects while promoting a healthier indoor environment free from harmful chemicals. Sustainable housing was once a niche concept, but it has moved its address to the front lines of architectural innovation and urban planning.
Designer Rachel Scheff used the home’s spectacular ceiling, woodwork, and stained glass as the inspirations for her fanciful, flora- and fauna-filled foyer. “It was one of my favorite rooms in the house because it was the one that had the most history preserved, and I wanted to really celebrate that,” she told AD PRO. For her Foyer of Enchantment, Scheff installed a custom mural by Hattas Art Studios, a John Richard chandelier dripping with glass leaves, a silk wall covering by Aux Abris, and organic furniture created with Amorph Studio.
