Alternative heating systems for northern remote communities: Techno-economic analysis of ground-coupled heat pumps in Kuujjuaq, Nunavik, Canada.
Nunavik is a subarctic remote region covering the northern third of Québec, Canada, where low efficiency and environmentally adverse diesel furnaces are currently used to meet residential heating demand. Studies focusing on building heating alternatives in subarctic climate are limited and hence, th...
