TFG Asset Management’s latest industry report on hotel sustainability, The Hoteliers’ Guide to Going Green, has revealed that in a typical 4-star hotel, 70% of energy consumption comes from the HVAC (Heating, Ventilation & Air-Conditioning). From an Asset Manager’s perspective, this figure highlights the urgent need to adopt cost-effective strategies to operate HVAC system at optimum temperatures and reduce heat loss.

Before implementing any programme, it is mandatory to understand the appropriate temperatures recommended for each area in a hotel property. The guideline below, provided by Dubai Electricity & Water Authority (DEWA), presents the summary:

Room Type

Temperature °C

Lobby and hall areas

22 – 24

Guest bathroom

26 – 27

Guest bedrooms (when used)

20 – 22

Restaurants and dining areas

22 – 24

Laundry areas

24 – 26

Swimming pool

≈ 22.5

It is the duty of the Asset Manager to ensure the guideline is followed by both staff and guests. One initiative recommended is to install automated systems to control processes.The hotel can use a programmed time setting switch to inform staff when heating, ventilation and cooling is required. The controls should be set appropriately to the occupancy of the hotel. Monitor sensor thermostats can be installed in guestrooms, which automatically switch on the appropriate air-conditioning temperature when a room is occupied and switch it off when a room is left vacant. This will ultimately help reduce energy usage and associated costs.

It is revealed in the Hoteliers’ Guide to Going Green that the automation control system is classified as a low-cost practice in which the payback period for the solution should range between 6 and 18 months. The Asset Manager is responsible for acknowledging that such practices will impact positively on the bottom-line with a reduction in utility expenses.

“At TFG Asset Management, we see green practices as an opportunity, and we believe that all hotel practitioners, owners and asset managers should agree on this. Not only do they impact positively on the environment, but also create a commercial advantage and improve financial performance in both top-line and bottom-line,” said Mariano Faz, Head of TFG Asset Management. “The challenge for asset managers is to search, analyse and implement cost-effective solutions with short pay-back time and hence high returns on investment.”
