Feasibility Study  

A feasibility study paves the way for  success.

You can request a relatively low-cost feasibility assessment to determine what it will take to bring the building up to the PHIUS+ 2018 standard to help you decide if passive house design is a worthwhile endeavor. The cost varies depending on the type and size of the building, but it's basically a rapid preliminary energy model using the design you already have to estimate the R-values needed for the envelope and windows.

The more we know about a project, the more accurate the energy model will be. The following documents are required:

  • Set of Preliminary Drawings (floor plans, elevations, sections, etc.)

  • A 3D Massing Model (if applicable- Revit ('15), SketchUp ('16), 3D AutoCAD ('15)) to accelerate geometry loading into WUFI® Passive

  • Preliminary Site Photos/Location to analyze potential summer/winter shading

  • Mechanical Narrative (if available)

  • Additional data such as occupancy/use schedules, planned equipment, and so on.


What does a feasibility study include:

Feasibility studies are a rapid guess at the building systems you'd need to fulfill the standard, based on a number of assumptions and defaults, but they're quite useful early on.


The following are included in the report:

  • WUFI® Passive report on preliminary annual energy consumption

  • To fulfill PHIUS+ 2018 criteria, target building-envelope performance values.

  • WUFI® Passive energy model Comparison of energy utilization vs. code (optional)


This study also assists the project team in beginning to consider adding passive building principles into their project early on.

For developers, architects, and anyone interested in PHIUS+ certification, we finalize the model throughout the project's design process.
