Cerami & Associates completed a review of the HVAC systems serving various locations inside Safeco Field. Included in this list were the Mariner’s team store, the stadium’s public restrooms, and the team guest suites and skyboxes. Cerami reviewed the interior acoustics of the suites at Safeco as well.
We made recommendations for the appropriate heat pump units to be installed in the restrooms as well as detailing the layout for the exhaust system. The mechanical units located adjacent to guest suites were fitted with vibration isolators and thick batt insulation was added between the walls and above the ceiling. In addition, sound attenuation blankets were specified for the suites and Cerami’s team recommended that the architect replace the plywood ceilings with more acoustically absorptive material.
The Mariner’s team store, located within Safeco, used several air conditioning units to maintain the desired temperature, but disturbed both the employees and patrons of the store with its loud noise. Cerami’s acoustical consultants proposed three options to mitigate the noise; the first was to re-locate the units to a storage area; the second was to add sound attenuation packages to the air conditioners; and the third was to encase the unit in a sound enclosure constructed out of sound attenuation blankets.
