Passive House Consulting

Passive House consulting supports projects from early design through certification, applying the most demanding energy and comfort standards in the industry. RDH works across both the PHI and PHIUS certification pathways. PHI is the European-origin standard applied on Canadian projects through organizations such as the Passive House Institute Canada; PHIUS is the North American adaptation used on US projects, with its own climate-specific targets and certification process. Our services cover design consulting, energy modeling, detailing, verification, and coordination across both pathways.

• Passive House design provides support for detailing, modeling, and integration of Passive House principles from schematic design through construction documentation.
• Passive House verification delivers third-party review and modeling quality assurance to meet certification standards.
• Passive House certification coordinates readiness reviews and certification submissions with PHI or PHIUS bodies.
