Passive House

North Park Passive House Exterior

At RDH we are always planning for the future. Nowhere is this more evident than in our work with high-performance buildings. As industry standards have grown and evolved, so too has RDH, constantly working on the forefront of green building design and construction.

Expanding Expertise

We are excited to announce, as part of our evolution, that Red Door Energy Design Ltd., a long-time industry partner with RDH, has merged its Passive House consulting and certification operations with RDH Building Science.

Red Door founder, Monte Paulsen has joined the RDH team as a Passive House Specialist. Monte is a Passivhaus Institute-accredited certifier, trainer, and consultant. He was a founding board member of, and regular instructor for, the non-profit known as Passive House Canada. As one of Canada’s most experienced Passive House professionals, he will lead RDH’s Passive House business in British Columbia, and will facilitate development of Passive House capacity among RDH teams across Canada and the U.S.

While interest in Passive House has risen across North America, Vancouver in particular has seen a rapid rate of growth in large (multi-unit or multi-purpose) Passive House buildings, largely inspired by the City of Vancouver’s Zero Emissions Buildings plan.

As key consultants on nearly all of Vancouver’s leading large-scale Passive House projects, RDH has established itself as a leader in this domain. With a strong foundation of innovative project work, we will continue to learn and grow. With this merger, RDH is excited to continue our work in Passive House, bringing expanded expertise to our comprehensive Passive House consulting services.

Passive House Consulting Services

Our Passive House Consulting services begin with RDH’s expertise in building envelopes. We can perform design concept review, risk review, construction document review, construction field review, and other services traditionally associated with our Building Enclosure Consulting. Additionally, RDH performs PHPP model calibration, whole building air leakage testing, and building science and post occupancy research.

RDH Building Science, with Monte Paulsen on board, is now one of just two Passivhaus accredited certifiers in Canada and can offer services to certify Passive House buildings, EnerPHit retrofits, and low energy buildings anywhere in the world.
