Project Overview
Radisson Blu Cork, a premier hotel in the heart of the city, sought to enhance sustainability while reducing operational costs. The hotel’s function rooms were heated by an ageing gas system, and the kitchen relied on gas boilers for domestic hot water (DHW). The client’s goal was clear: eliminate gas heating, cut energy use, reduce carbon emissions, and improve long-term operational efficiency.
GS Renewable was engaged to design and implement a high-performance heat pump system that could meet these objectives without disrupting hotel operations.
Client Objectives
Eliminate Gas Heating
-
Replace the existing gas heating system in the hotel’s function rooms with a fully electric, low-carbon solution.
Reduce Operational Costs
-
Achieve measurable annual savings for the function rooms and kitchen DHW.
Lower Energy Consumption
-
Reduce overall energy use and reliance on fossil fuels.
Cut Carbon Emissions
-
Significantly decrease the hotel’s carbon footprint.
Results
GS Renewable designed and installed a high-efficiency heat pump system tailored to the hotel’s needs.
Key Features Included:
Function Room Heating: Electric heat pumps replaced gas-fired units, providing reliable and controllable heating.
Kitchen DHW: Heat pumps supplied domestic hot water efficiently, reducing reliance on conventional boilers.
The system was carefully phased to avoid any disruption to hotel guests, with most installation completed during off-peak hours.
