SSM completed a study to provide options to ventilate the “attic” spaceof Weightman Hall. The space contained two air conditioners discharging hot condenser air into the space. The existing ventilation of this space was not sufficient to remove the heat leading to an increased load on the air conditioners and decrease in performance of the units which are rated at ambient temperatures of 95 deg. F. Temperatures in the attic space were believedtoexceed 120 deg. F.
SSM explored options to ventilate the space housing the air conditioners to provide a satisfactory ambient condition or modify the installation to mitigate the impact of being installed in an interior space. SSM mechanical engineers surveyed the site and documented existing conditions including several existing and apparently abandoned duct systems in the vicinity of the air conditioners and the space in which the units are housed and the surrounding areas in sufficient detail to develop ventilation options. The final report included three options for creating a satisfactory environment for the operation of the air conditioning units and budgetary construction costs for each scenario.
