According to a study by consultants PwC, the biggest costs assumed by hotel establishments are human resources (39%), followed by provisioning (22%) and in third place, water and energy (with an average of 9%). Although this figure varies depending on occupancy, category, size, climate zone and seasonality, the energy consumption of hotel establishments represents a significant item on their balance sheets – between 4% and 25%, out of which, around 60% corresponds to thermal consumption.
This is distributed into more or less equal parts between cooling (18-21%), heating (15-20%) and domestic hot water – DHW (24%). Heating, DHW, laundry and spa and swimming pool areas are the most usual consumers of energy, normally in the form of hot water, while the kitchens use mains gas.
