This thirteen story office tower consisting of 7,800 sq. meters of office space, is located in the heart of downtown Calgary. The project includes two levels of underground parking and utilizes compartmental units for each floor. Our role involved both fundamental and enhanced LEED® commissioning of the mechanical, electrical and controls systems. This municipal building was renovated in phases and each floor was brought on line independently. RSR has been involved in the project since its inception. The Andrew Davidson Building is part of the City of Calgary's "Sustainable Energy Initiative" where the building is directly connected to Enmax's District Energy Centre and includes many other sustainable energy features and elements.
