Winners of Phius’ 2026 Passive Projects Design Competition point to growing use of Passive House strategies in larger and more complex buildings, including multifamily and affordable housing. The competition offers evidence of developer and designer interest, but the available report does not provide project-level performance data or details on costs and affordability.
Winners of the 2026 Phius Passive Projects Design Competition highlight the spread of Passive House design into multifamily and affordable housing, a shift that shows how the high-performance standard is being applied beyond single-family homes. Phius says designers and developers are using its strategies in increasingly large and complex buildings, though the published report does not provide detailed cost or energy-performance figures for the winning projects.
The competition, sponsored by Phius, is in its 11th year, excluding 2024, when it paused. The awards provide a snapshot of the building types being designed around Passive House principles and the standard’s expanding use in projects that serve more residents than a typical house.
Phius co-executive director Katrin Klingenberg said the competition has consistently included a mix of building categories. The report describes the latest winners as evidence that designers and developers are taking high-performance approaches into larger projects. It identifies multifamily and affordable housing as areas making headway, but the supplied material does not name the projects, locations, award categories, or developers.
The report frames Passive House as a design approach built around climate-responsive choices and reduced energy demand. Strategies include using building form and materials to make use of sunlight, limit exposure to wind and rain, and maintain indoor comfort. Advances in energy modeling, glazing, appliances, renewable energy and HVAC equipment have also helped expand what designers can apply in larger buildings, according to the report.
Scaling High-Performance Housing
Multifamily buildings can apply energy-saving design to homes serving many people within a single project. If Passive House strategies are incorporated into affordable housing, they may also shape the energy performance and indoor comfort of homes intended for residents with limited housing options. These are potential benefits of the approach, not measured outcomes established by the competition summary.
The competition matters because it brings attention to whether a standard often associated with houses can be used in more complex building types. Wider adoption could influence design practices among developers and architects, but the report does not establish how many projects are being built, how much energy they save, or whether their construction costs differ from conventional alternatives.

From Houses to Larger Buildings
Passive House, also known as Passivhaus, draws on climate-responsive design principles used long before the standard was formally codified. The report traces its modern development to the 1990s, when professors from Sweden and Germany shaped those principles into a high-performance building standard.
Phius’ annual design competition is one way to observe how the approach is being used. Its 2026 results follow a broader evolution described in the report: advances in building technology and energy modeling have supported applications in buildings that are larger and more complex than single-family homes. The competition’s hiatus in 2024 means its year count does not correspond to an uninterrupted sequence of annual awards.

Project Costs and Results
The available report excerpt does not identify the winning projects or provide construction costs, energy-use results, emissions data, or resident outcomes. It is also unclear how many of the award-winning projects are affordable housing, what affordability measures they use, or whether they are completed, under construction, or still in design.
The competition indicates interest in applying Passive House principles to larger buildings; it does not, by itself, show that the approach is affordable at scale or that each project will meet its intended performance targets. Comparisons with conventional buildings would require project-specific data and a clearly stated baseline.
Details Needed From Winning Projects
The next useful information would be project-level descriptions from Phius or the developers, including locations, building sizes, affordability criteria, construction status, and the design measures used. Energy use and cost data, once available, would help readers evaluate how the projects perform against their targets and against comparable buildings.
For now, the 2026 competition results offer a sign of where designers and developers are applying the standard, while the practical effects on cost, energy use, and residents remain to be documented.
Key Questions
What is the news about Passive House design?
The 2026 Phius design competition highlights the use of Passive House strategies in multifamily and affordable housing, extending beyond the single-family homes often associated with the standard.
What does Passive House design aim to do?
It uses climate-responsive design and building systems to reduce energy demand while maintaining indoor comfort. The report points to measures involving building materials, sunlight, glazing, appliances and HVAC equipment.
Does the competition show that affordable Passive House buildings cost less?
No. The supplied report does not give construction-cost comparisons or show whether the winning projects cost less than conventional buildings.
Are the winning projects already built?
The available report excerpt does not say which projects won or whether they are completed, under construction, or in design.
What information would show how well the projects perform?
Project-specific energy-use results, cost data, building details and comparisons with a stated baseline would help establish performance. Those details are not included in the available material.
