This thesis explores the concept of reuse and recycling of waste heat generated by typical office buildings, in order to create an environmentally benign architecture that contributes to the public and social realm of the city. The case study is a mid-size public institution located in downtown Halifax, Canada, in the institutional and symbolic heart of the city on the Grand Parade. The proposed building reconceptualizes public space, providing amenities to a wide range of users, while creating a symbiotic relationship between private and public institutions. The proposed program is an inner city YMCA.
