Renovation of an educational facility in Fort Davis, Texas. Completed plans call for the renovation of a educational facility.

Replace the existing air-cooled chiller with two new air-cooled chillers of increased total capacity and selected to achieve both summer and winter design conditions. The new chillers would be located on new equipment pads to the southeast of the HET building. Replace the two existing air handling units (AHUs) with two new AHUs, designed to satisfy cooling loads while avoiding ice formation on the cooling coils during winter conditions. In this case, design winter conditions represent high humidity/subfreezing temperature ambient conditions. Install a new fabric supply ductwork distribution system that creates a displacement type environment within the dome to minimize temperature stratification.
