CIRS wanted to achieve many sustainability goals to become the most sustainable building on campus, but in this presentation, we will focus on the three of these goals. These goals are to manage resource consumption, be cost-effective in construction and operations, and embrace passive strategies to maximize daylight and natural ventilation. From the previous lecture, we know that 50% of commercial operating costs are spent on space heating, whereas lighting comes as the second biggest expense at 15%. Because of this, we wanted to focus on the movement of heat and ventilation in the CIRS building. Sounds of Sustainability is an auditory installation on the exterior doors of the building – broadcasts sounds of howling wind when doors are open. It creates an auditory connection to the movement of conditioned air out of the interior spaces of the building.
