Project Key Features

GEA designed the mechanical, electrical, plumbing, and fire protection systems of this new mixed-use building project, in addition to providing energy modeling and commissioning services. Spanning a vast expanse of 806,000 square feet, this ambitious endeavor encompassed a diverse array of components, including commercial spaces, community facilities, a waterfront esplanade, parking facilities, and residential units. Notably, the residential component comprised two market-rate rental towers, soaring to 30 and 40 stories,  emerging from an affordable housing podium.

A notable challenge faced by GEA was the implementation of a Variable Refrigerant Flow (VRF) HVAC system without sub-metering, as per the owner’s specifications. This entailed the provision of individual condensing units for over 500 apartments, necessitating tedious planning and execution. To address this challenge, GEA meticulously measured the length of refrigeration piping required for each unit, ensuring precise allocation and installation to meet the project’s requirements.

Moreover, GEA’s expertise extended to optimizing the utilization of limited rooftop space, where accommodating the multitude of condensing units posed logistical constraints. Leveraging Computational Fluid Dynamics (CFD) analysis, GEA analyzed airflow dynamics around each air-cooled condensing unit, ensuring adequate ventilation and optimal placement to maximize efficiency and functionality. Through sensible planning and innovative solutions, GEA navigated complex design challenges to deliver a cohesive and efficient MEP system tailored to the unique demands of the project.
