Investing In Passive Multifamily Projects


Upfront planning is the best and cheapest way to reduce risk. That is where the WUFI Passive building modeling software earns its pay. Based on science and data from thousands of passive buildings, the modeling software is remarkably accurate. You can begin the process with a feasibility study before building an energy model as a back-of-the-envelope check on what it will take to get your plans up to PHIUS+ Standards.


Quality Assurance is built into the process

The next step in reducing risk is verifying that the plans are executed according to the design. PHIUS+ is the only passive building certification program requiring third-party quality assurance/quality control (QA/QC).

The rigorous QA/QC process is a vital independent check that verifies to investors and program managers that the projects getting built will perform as modeled.


PHIUS has credibility with government agencies

The PHIUS+ Standard is promoted by the US Department of Energy (DOE) as the next level of high-performance building standards because it incorporates industry-accepted building science.

  • PHIUS+ certification requires that projects comply with DOE-accepted performance practices including the US Environmental Protection Agency’s Indoor airPLUS and WaterSense programs.
  • PHIUS+ certified residential projects also qualify for the DOE’s Zero Energy Ready Home program, which recognizes high-performance homes that are energy efficient enough to offset most or all annual energy consumption with renewable energy.


Partner with DOE on Financing

The DOE offers a Lender Partner Agreement whereby lenders can finance homes easier and with lower risk because these homes are built to much more rigorous standards than minimum code and afford occupants significantly lower operating costs.
