Consulting for Passive Building

Passive House architecture doesn't just apply to residential building. The concepts are applicable to commercial buildings too.

Liminal Architecture provides passive house consulting services to architects and architecture firms, general contractors and builders, and individual home and business owners, all who desire to lower energy costs, improve air quality, and/or limit environmental impact, locally and globally. Mark Graham is a Certified Passive House Consultant, CPHC, per the Passive House Institute United States, PHIUS (link to organization).


What is Building using Passive House Design Principles?

The principles used to define Passive House Construction (which also apply to commercial construction as well) make this form of architecture and engineering the most energy-efficient way to construct buildings in the world. Passive House is a performance standard for eco-friendly construction of homes and businesses.

The PHIUS, which is the certification organization for the United States, defines the Passive House standard with five key principles. Passive building comprises a set of design principles used to attain a quantifiable and rigorous level of energy efficiency within a specific quantifiable comfort level. “Maximize your gains, minimize your losses” summarize the approach. To that end, a passive building is designed and built in accordance with these five building-science principles: 

  • It employs continuous insulation through its entire envelope without any thermal bridging.
  • The building envelope is extremely airtight, preventing infiltration of outside air and loss of conditioned air.
  • It employs high-performance windows (typically triple-paned) and doors
  • It uses some form of balanced heat- and moisture-recovery ventilation and uses a minimal space conditioning system. 
  • Solar gain is managed to exploit the sun's energy for heating purposes and to minimize it in cooling seasons.
