Portola Hotel and Spa Pursue LEEDTM for Existing Buildings Operations and Maintenance through Commissioning.

commissioning project

Project Summary

200,000 square feet

75 ton packaged roof top air conditioner

No existing integrated building control system

4 smaller roof top air handlers (combination of cooling coils and packaged air conditioners)

4 system exhaust fans

40 ton Chiller and chilled water distribution system

Domestic hot water system heated by cogeneration system

This hotel and spa is pursuing LEED for Existing Buildings Operation and Maintenance certification through the use of a Commissioning Agent. Axiom EngineersSM verified equipment performance to determine low-cost and no-cost improvement options. Commissioning activities included the installation and analysis of over 100 local data loggerss. These data loggers provided information that helped identify system inefficiencies and equipment failures.

These improvements are estimated to result in over 20% energy savings with a less than one-year payback. Systems that will benefit from commissioning include eight large packaged rooftop air handlers, the chilled water system, the 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.

Accomplishments

  • » Performed first complete building equipment trending analysis since construction (1978).
  • » Provided low cost and no cost energy savings options estimated to result in 20% energy savings.
  • » Provided numerous equipment operation improvements resulting in saved maintenance requirements.
  • » Provided low cost options to improve indoor air quality from analysis of air balance report.
