Project Description

North Shore University Hospital was facing challenges with pressure, temperature, and humidity in their ambulatory surgery center when Bladykas Engineering was brought on board to uncover the root cause and provide solutions. Our approach involved a thorough review of existing drawings, verification of as-built conditions, acquisition of preconstruction airflow readings, and collaboration with the facility engineer to manage the temperature controls. Calculations were meticulously performed to troubleshoot the identified conditions.

Our investigation revealed several factors contributing to the issues. An air handling unit was incorrectly replaced, leading to an imbalance and lack of control between the supply and return airflow, attributed to the coexistence of bypass Variable Air Volume (VAV), true VAV, and plenum returns in the space. Additionally, the Type 1 Essential Electrical System (EES) had commingled circuits; hence, we separated them to correct the system. The implementation of our recommendations not only resolved the pressure, temperature, and humidity challenges but also ensured the Type 1 EES was in compliance with code requirements.
