One South First rises at the northernmost site of the Domino Sugar Factory development. This two-towered building will be 42 floors and the tallest building in Williamsburg; consisting of rental apartments, offices, and retail space. The façade is constructed of angled, precast concrete with deeply-recessed windows and faceted components and the façade is designed to self-shade with each elevation formed to respond to its specific solar orientation. Ennova worked in a design assist capacity and provided product selection, performance validation, thermal and acoustical modelling, BIM coordination, and engineering support.
