Monmouth County Vocational School District (MCVSD) contracted with PS&S to perform an HVAC system evaluation for the High Technology High School (HTHS) located on the Brookdale Community College Campus in Lincroft, NJ.

The Opportunity

HTHS was built over time in three separate phases of work over multiple years (1992, 1995, and 2002). The HVAC systems and controls were 20 years old and at the end of their useful life, requiring replacement. Repairs were not feasible for the existing systems. Therefore, an HVAC assessment was warranted to define a path forward for the scope, scale, cost impact, and phasing schedule for the proposed work.

The Challenge

The design team was challenged with conceiving an efficient system selection that could be implemented over a multi-year period. The proposed HVAC systems had to address the current code requirements and fit within the existing building constraints for the (3) building sections.

The PS&S Solution

PS&S recommended removing all interior air handling units (AHU’s) within the building sections due to space restrictions as it hinders access for maintenance. We suggested reusing existing duct work and piping, where possible, and proposed to extend duct work. Additionally we advised reusing / extending services to the new ground-mounted roof top units (RTU) which were placed around the building perimeter to service each building section independently. The new RTU’s are to be placed in similar locations as the existing ground-mounted equipment. The existing fenced enclosures were noted for expansion where required. Two new ground-mounted equipment locations were added to adequately service areas to meet code compliance. Two ground-mounted condensing units were to be removed. Ground-mounted equipment required grading and site changes around the building and an acoustical review of the proposed design by an independent sound consultant will be performed.
