Our work has been featured in several articles and magazines highlighting our pioneering approach to Zero Energy and Passive House construction in our extreme climate. Keep in mind that some of the articles are from third parties and contain some technical discrepancies.

Subarctic Passive House Case Study:
A Superinsulated Foundation &
Vapor Diffusion-Open Walls

By Bruno Grunau, PE

This is an independent study of the passive solar home built by REINA’s Owner/Builder Thorsten Chlupp. The Cold Climate Housing Research Center monitored the performance this superinsulated home that features innovative, high-efficiency building and mechanical systems, and has a super-insulated foundation, integrated heat storage system, and an open wall design—without a traditional vapor barrier—allowing vapor to diffuse through the wall. Sensors were placed in the wall to record temperature, relative humidity, and moisture accumulation in the walls for 13 months. Thorsten’s home demonstrates that buildings in subarctic climates can perform well without traditional heating systems, and it presents an innovative alternative for high-efficiency construction.
