    University’s marine science lab finds extreme savings with variable-speed chiller plant

    Located close to various waterways, the University of North Carolina Wilmington (UNCW) takes marine science seriously. Its new MARBIONC Building ā€” a 69,000-square-foot interdisciplinary research facility for marine biotechnology ā€” provides labs for lease to commercial enterprises that require reliable, energy-efficient 24/7/365 cooling. Faced with high humidity and mid-Atlantic climate variations, the building required a chiller plant that could take advantage of a wide range of operating conditions and still run reliably.

    Engineering Tomorrow doubles new DOAS efficiency

    Improving indoor air quality by increasing the amount of outdoor air (OA) entering a building is necessary in many facilities. Depending on occupant density, some buildings may require 20 cubic feet per minute (CFM) of outdoor air per person, a volume of air that can increase air-conditioning costs.
