This project proposes creation of heat refuge infrastructure for underrepresented working populations in New York City, focusing on the Urban Heat Island Effect. Site selection targeted the edges of these heat masses, where large thermal masses meet open spaces, acting as thermal regulators and microclimatic buffers. This tension edge presents socioeconomically and programmatically contentious opportunities to develop unique urban and climatic conditions. The chosen site is on the eastern edge of lower Manhattan, at the waterfront where Wall Street meets FDR Drive. Formally, this mass edge encompasses a dense population and service catchment zone, while climatically, the inherent discrepancy on both sides of the described heat mass edge resulting in natural ventilation flows opportunities. The project addresses un-officed workers, including street vendors, traffic police, couriers, construction crews, and sanitation staff, who are transient and essential yet often overlooked. The infrastructure captures heat from building mechanical systems to create passive cooling, drawing air from the water surface into the city. It includes resting areas, gardens, toilets, showers, lockers, e-bike charging units, and a bike shop. Additionally, it features public cooling areas, commercial spaces, an outdoor recreation pool, and modular structures for emergency shelters, accommodating displaced persons on various time scales.
