Project context

Two office spaces with a standing dividing partition were requested to be converted into one laboratory space. This required adding a new dual-duct variable air volume terminal unit to tie into the existing dual-duct system at the building. In addition, an abandoned make-up air ductwork in the adjacent space was demolished and the roof penetration was reused for a new general exhaust fan to provide negative pressurization for the new lab space. Fire-dampers were utilized to ensure that the fire-rating of walls were maintained.

My work

Using original building drawings, site-visits and future equipment lists, I performed a space heat-load with Excel, including building envelope heat gains and losses and interior heat gains from people, lighting and existing and future equipment lists. Special care was given to ensure that the fire-rating of the dividing walls were maintained, through selection of fire-dampers, and that the process and instrumentation diagram (P&ID) and logic would meet laboratory operating requirements, while integrating fully with the rest of the building HVAC system. ## Engineering

Section view of exhaust ductwork.
I particularly enjoyed adding in the structural details, such as the concrete beams' shapes and spans, as can be seen in this view. Old structural details sometimes have better methods of illustrating simply their overall topology. Once you have enough details, a ductwork section view can actually help out the contractor!
