Hotel Energy Management System

Situation

The Hilton Marina Fort Lauderdale is a full service hotel on Florida’s coast with 589 guest rooms in three buildings, 33 boat slips and 21,000 square feet of event space. In this climate, HVAC systems are constantly battling hot, humid outdoor air in order to maintain comfort levels for hotel guests and visitors. At the same time, with limited staffing to monitors these proactively, this became a staffing challenge. In addition the building management system only controlled the common-space air handlers required significant time to address these problems.

Project

hilton_w_map1Groom Energy approached the building complex in a holistic way. After performing utility data analysis, on-site data logging, a blueprint review and in-person evaluation of the facility, Groom Energy developed incremental, justified, investable upgrade projects which could maximize both investment returns and comfort levels. As is often the case, significant savings were identified from within the property’s interrelated systems and determining how to maintain balanced conditioning with dynamic weather and occupancy inputs.

Groom Energy designed and delivered a comprehensivehilton_interior turnkey implementation with property-wide energy metering, efficiency upgrades and a building management system (BMS) expansion. Engineering and finance departments gained visibility to where energy was being used and was alerted earlier to significant issues. The BMS was tuned to automatically adjust chillers for influxes or lulls in need. Simple easy upgrades addressed an assorted number of mechanical system deficiencies.

The upgraded BMS could then ensure that the vital actuators and dampers were operating properly. Finally Groom Energy made certain similar future one-time fixes could handled by engineering and maintenance, as well as included as preventative assessment measures in order to maintain the energy savings after all upgrades had been completed.
