The initial approach adopted at the Hotel was to upgrade the building’s HVAC system. This was done through the installation of a multi-pipe heat pump. Afterwards an AHU upgrade was carried out.
Energy saving opportunities were first addressed with the cooperation of the hotel staff. Hotel management then recognised that to make further inroads in energy savings, investment was needed and this included lighting and refrigeration solutions.
Lighting upgrade from halogen to LED was implemented in some of the hotel zones. For boiler upgrade, a range of options were assessed including CHP with final decision to upgrade the system to a multipipe heat pump to match the heat demand. Heat recovery on the dishwasher was also installed which provided large savings in a very timely payback of 2.7 years. The heat exchanger was also upgraded on site.
Guided by sustainability principles outlined by SEAI, the hotel team collaborated with Celtic Dynamics to deliver measurable energy savings.
