The initial approach adopted at Sligo Park Hotel was to install an energy monitoring system (EMS). This was to accurately demonstrate and understand the energy use throughout the hotel and leisure centre. The EMS was installed during 2013 using wireless interfaces. Energy saving opportunities were first addressed with co-operation of the hotel staff. Hotel management then recognised that to make further inroads in energy savings, investment was needed and this included lighting and boiler upgrades.
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 oil boilers to LPG condensing type with cascading operation to match the heat demand. The oil boilers were over 16 years old with thermal efficiency (65-70%) well below that of modern condensing boilers (90 %+). The lifespan of the existing boilers is typically 20 years so it was opportune to review their operation and invest in condensing energy efficient type and change to LPG also.
“The starting point for us was to monitor and understand energy use throughout the hotel and then invest in specific measurable energy upgrades. We are very pleased with the energy savings achieved since 2013”,
