Project 2 – Science Building HVAC

Evaluation and Replacement

Customer Contact Information:

Richard Kolhoff, Director of Construction for RCDST

Total Contract Cost:

Project Cost: $48,200

Type of Contract:

Building Analysis and Construction Agreement

Scope of Services:

WWEC performed an evaluation on the existing 30-Ton HVAC Rooftop HVAC Unit (RTU) for the Science Building at SPCHS. Work included an evaluation of existing building loads, building air infiltration test, fresh air / ventilation requirements, equipment sizing, energy efficient alternatives, and HVAC equipment selection. WWEC’S evaluation revealed existing system was oversized and did not provide adequate fresh air as per current Florida Mechanical Codes. The “rightsizing” of the existing HVAC system allowed SPCHS to upgrade to Carrier 25-Ton Rooftop system with 2-Stage Cooling, motorized CO2 demand ventilation damper (to provided adequate fresh air), a “Humid-MiZer” adaptive dehumidification system for outside air, and an “E-Coated” corrosion protection for the condensing coils. The upgraded energy efficient and sustainable features were included on the “rightsized” 25-Ton RTU at a comparable price of the 30-Ton alternatives./p>
