The hotel was particularly looking for a system that would be energy efficient and environmentally friendly. An energy model was created for the whole hotel, which was then configured to simulate the energy consumption during a typical year (based on occupancy rates provided) for various heating, ventilation, and air- conditioning (HVAC) system types, including an air-cooled chilled water system, a water-cooled chilled water system and VRV units. The replacement began in September 2013 and completed in September 2014. A Samsung VRV system has been installed. The room units were size to control humidity inside the guest rooms to avoid mold and odours.
