Axiom Engineers: Commissioning


This hotel and spa was pursuing LEED for Existing Buildings Operation and Maintenance through the use of a Commissioning Agent. Equipment performance was verified through installation and analysis of over 100 local data loggers.

Commissioning included installation and analysis of installed data loggers to determine low cost and no cost improvement options. Systems that will benefit include eight large packaged rooftop air handlers, chilled water system, domestic hot water system, and numerous fan coils. Improvements include installing demand control ventilation, improved utilization of installed economizers, and updating existing lighting systems with compact fluorescents. LEDs, and higher efficiency fluorescents. Improvements are estimated to result in over 20% energy savings with less than 1 year payback

Notable Engineering Features

• 200,000 sq. ft.
