Description
H2Engineering has provided design and commissioning services for multiple projects in the Pepper Building for the State of Florida, most recently including a data center renovation and chiller plant renovation.
The data center project consisted of the renovation of a 9,000 SF data center and adjacent offices. Engineering services included HVAC, Fire Protection, Electrical and Telecommunications Design as well as Construction Administration, LEED Administration, and Fundamental Commissioning for LEED. The HVAC design consisted of a new chilled water system with a modular air-cooled chiller and variable volume primary distribution system, VAV boxes with electric heat, computer room air conditioning units and energy management control system. An emergency generator was supplied for full emergency power.
The chiller replacement project included the replacement of the three existing chillers with new centrifugal machines, including rebuilding the existing three cooling towers and providing refrigerant monitoring system and purge ventilation system per ASHRAE Standard 15. The pumping arrangement for the plant was reconfigured from two separate primary-secondary distribution loops to a single variable flow primary arrangement, so all the chillers will operate on the same plant. During the chilled water optimization part of the commissioning process, it was discovered that several of the existing control sensors throughout the building were not being used correctly and had resulted in increased energy usage for years.
