Winners of Phius’ 2026 Passive Projects Design Competition show how Passive House strategies are being applied to larger, more complex buildings, including multifamily and affordable housing. The competition points to growing developer interest, but the supplied report does not provide project-level energy results, costs or details about the winning affordable-housing projects.
Phius’ 2026 Passive Projects Design Competition highlights the spread of Passive House strategies into multifamily and affordable housing, as designers and developers apply the standard to buildings larger and more complex than single-family homes. The annual competition’s latest winners offer a snapshot of that market shift, though the available report does not specify project-level costs or measured energy performance.
The competition is in its 11th year, excluding 2024, when the program paused. Phius co-executive director Katrin Klingenberg said the event has included a mix of building categories over its run. The latest set of winners points to a broader range of projects using Passive House approaches, according to GreenBuildingAdvisor’s report.
Phius said in a press release that the standard has grown “from an idea to an ecosystem,” with design teams and developers applying high-performance strategies to increasingly large and complex buildings. The source material identifies multifamily and affordable housing as areas where the approach is making headway, but does not list the winners, project locations, building sizes or specific design features.
Passive House design focuses on climate-responsive planning and building performance. The report describes strategies such as making use of sunlight, limiting exposure to wind and rain, and maintaining interior comfort. It also credits advances in energy modeling, glazing, appliances, renewable energy and HVAC equipment with helping the standard develop.
Why Larger Housing Projects Matter
Multifamily and affordable housing projects can bring high-performance design to more residents than a single-family home. Their inclusion in a design competition focused on Passive House suggests the approach is being considered for a wider range of development types, not just custom houses. That matters to housing providers and design teams weighing building performance alongside project constraints.
The report does not establish that Passive House projects are cheaper to build, reduce rents, or produce a particular level of energy savings. Those outcomes depend on project details and would require evidence beyond competition recognition. Still, the expansion into larger buildings indicates growing professional interest in applying the standard at a scale relevant to housing supply.

From Homes to Complex Buildings
The report traces the modern Passive House standard to work in the 1990s, when researchers drew on longstanding climate-responsive building practices and formalized them into a high-performance framework. Its principles include responding to local conditions and using design and engineering choices to support indoor comfort.
Phius’ competition provides one way to observe how those ideas are being used across building types. It has run for 11 years, with a break in 2024. GreenBuildingAdvisor says this year’s winners reflect changes in the standard’s application as technology and design capabilities have developed. The source provided for this article is an excerpt; it does not include the full competition results or detailed descriptions of the winning entries.

Project Costs and Results Unreported
The available report excerpt does not name the winning projects or explain which entries qualify as affordable housing. It also gives no figures for construction costs, energy use, emissions, operating expenses or resident outcomes. Those details are needed to judge how the design strategies performed and whether the results can be compared across projects.
The competition shows which projects received recognition, but awards alone do not establish measured performance after occupancy. It is also unclear from the supplied material how many submissions involved multifamily or affordable housing, or how the winners were evaluated.
Full Project Details Needed
Further information about the winning entries would clarify how the projects applied Passive House strategies, what building types and locations were represented, and whether the developers reported costs or operating results. The supplied report identifies the competition winners as evidence of broader adoption, but does not provide a timetable for additional results or follow-up studies.
For now, the confirmed development is the recognition of projects in Phius’ 2026 competition and the organization’s account of a growing range of building applications. Project-specific performance and affordability claims remain unverified in the available material.
Key Questions
What is the news about Passive House design?
The 2026 winners of Phius’ design competition reflect wider use of Passive House strategies in multifamily and affordable housing, alongside larger and more complex buildings.
What is Phius?
Phius is the organization that sponsors the Passive Projects Design Competition. Its co-executive director, Katrin Klingenberg, commented on the range of building categories represented in the competition.
Does the report show that Passive House housing costs less?
No. The supplied report does not provide construction costs, rents or operating-cost comparisons, so it does not establish whether the projects are less expensive than other housing.
Are energy savings from the winning projects confirmed?
The source excerpt does not give measured energy-use data for the winners. It describes the projects as evidence of wider adoption, but project-level performance results are not provided.
How long has the competition been running?
The competition is in its 11th year, not counting 2024, when it did not run.
