A demonstration house was previously built and commissioned in Iqaluit, Nunavut, Canada. The purpose of the overall effort is to develop and integrate technologies and evaluate the performance of a high-performance building located in the Canadian Arctic, while considering the unique social, economic, and logistical challenges associated with its remote location. Previous work consisted of monitoring and reporting on the energy use from heating between April 2016 and April 2017. The purpose of this next stage of research is to contribute experimental data of the prototype demand-controlled residential ventilation system in the extremely cold climate of Iqaluit, where the average annual outdoor temperature is approximately −9 °C. This paper outlines the development, implementation and monitoring of the carbon dioxide-based demand-controlled heat recovery ventilation system that took place between April 2017 and April 2019.
