Abstract

This research explores the potential of intermediate spaces as architectural solutions for incorporating nature-based approaches into public housing models designed for extreme cold climates. Intermediate spaces, situated between indoor and outdoor environments, foster positive connections to nature. Prior studies emphasize their potential to enhance occupant well-being through increased outdoor connectivity, while also serving as productive and affordable spaces. These spaces can feature transparent surfaces to maximize natural light, making them suitable for plant cultivation and greenery integration. The objective of this study is to optimize architectural parameters for intermediate spaces to support greenery production effectively. Specifically, the research aims to maintain indoor temperatures within an optimal range of 13–27°C – optimum temperature for plant growth - and maximize solar gain for plant growth. A numerical simulation model was developed to evaluate the performance of intermediate spaces by varying architectural parameters, including (1) transparency ratio and (2) space depth. Findings reveal that intermediate spaces with a transparency ratio of 40–60% and a depth of 5-7 meters achieve the highest duration of optimal temperature conditions and maximum solar gain, supporting plant growth and enhanced daylight exposure. These results demonstrate that integrating intermediate spaces into public housing models in extreme cold climates can contribute to Canada’s food security initiatives, particularly in Northern regions, by promoting sustainable indoor plant cultivation. This research underscores the value of nature-based solutions in addressing food security and enhancing the livability of public housing in harsh environments.
