Passa Associates Inc., Architects The firm is dedicated to the formulation of sensitive and imaginative building. It strives for architectural excellence in the exploration of ideas within the economic and environmental responsibilities that are demanded of all projects. Designs involve the multiple performance considerations of comfort, aesthetics, economics, energy efficiency and environmental impact. We believe that the thriving progression of our communities is dependent upon balancing practical requirements and the artifice of the built form in order to propel cultural expression to an enduring future. Our global natural abundance can then be preserved and enjoyed within our living buildings. PA Architects began the Green Building Movement of sustainable design in the Canada South area developing some of the most energy efficient institutional projects in the country since 2002. As initial members of the Canada Green Building Council the firm has LEED Accredited Professionals on staff to evolve LEED certification.
