Over the past decade, energy and environmental issues have become increasingly important in our society. Global warming, the constraints of fossil fuels or the introduction of renewable energies are the main concern. As all hotel professionals know, energy is an important part of their budget. They can, however, reduce their energy consumption without impacting the quality of the services they offer their customers. If, at first, you run out of budget to undertake major renovations, you can still save energy in the hotel industry. A simple change in behaviour and the introduction of small daily free gestures will allow you to save on your electricity consumption while giving a good image to your establishment. 

So what can you start with?

Before you start your process, take stock of your current consumption. You'll do another one some time after you've made these "small" changes to see the results of your efforts. In addition, communicating these results will stimulate the involvement of your staff. Here are some tips you can implement immediately to improve your energy performance: 

In the bedrooms

  • Adjust the temperature of the rooms, not according to the time, but rather in relation to their occupancy. An empty room does not need to be heated at night if it is empty, even in winter. All you have to do is turn on the heating some time before customers arrive, so that the temperature has reached a comfortable level. This prevents your customers from putting the appliances to the maximum to heat or cool the room faster. Systematize the shutdown of the heating or air conditioning system during the ventilation time of the rooms.
  • Limit the range of air conditioning control boxes to -- 2 degrees Celsius.
  • Prefer more economical individual minibars in the rooms. Better yet, remove them and replace them with beverage dispensers on each floor.
  • Choose light tones for your walls and decoration. This will avoid having to use the lights during the day.
  • Link electrical and electronic device management to the magnetic card. As a result, when the room is empty, all electrical equipment will be turned off and not in standby mode. If your electrical devices are not connected to a magnetic card, ask your staff to routinely turn off all standby devices such as televisions. Encourage your customers to do the same by placing a switch near the head of the bed.

In the bathrooms

  • Go around all faucets and toilets regularly to detect leaks as soon as possible and repair them. Review defective blenders.
  • If your toilet does not have a dual flushing system, insert a brick into the toilet tank to limit the amount of water consumed.
  • Replace traditional 25-litre-per-minute shower heads with shower heads delivering 9 to 12 litres per minute. Your customers will be delighted to enjoy a softer and more pleasant jet of water than usual!
  • Install foamers on faucets and shower heads.

In the common areas

  • Take care and particularly value access to the floors by stairs: this will prevent your guests from taking the elevator regularly.
  • Choose timers and adjusters without forgetting to check if the day of the week and the time (summer/winter) are correct.

Throughout the hotel

  • Choose low-energy, LED light bulbs. They have a longer lifespan: 40,000 hours compared to 2,000 hours for halogen lamps and 8,000 hours for compact fluorescent lamps (source Ademe). In addition, they also use five times less energy.
  • Dust fixtures regularly, both in the bedrooms and in the common areas. This optimizes their brightness.
  • Dust electric convectors regularly.
  • Review your ignition system in bedrooms and common areas: prevent a simple switch from turning on several lights, which are often useless, at the same time, and integrate presence sensors to prevent empty rooms from remaining illuminated unjust.
  • Replace your old heating and air conditioning equipment: very energy-intensive, so they are very expensive to use. Today, there are high-performance heat pumps and gas boilers that can provide both heating and air conditioning. These new equipmentwill allow you to achieve up to 40% savings compared to your previous installation. The use of ceiling fans during the summer is also an environmentally friendly and inexpensive solution to implement.
  • Nocturnal temperature drop: Take the heat accumulated during the day and schedule a drop in temperature around 10 p.m. or even earlier if possible. Keep pumping and filtering of water from hot tubs and other indoor pools to a minimum. During the night, 30% of water circulation is more than enough.

In the kitchens

  • Clean the grills at the back of refrigerators regularly and place them away from the cooking appliances. This will reduce their energy consumption. Never put hot food in the refrigerator.
  • Set out with cooks the rules of economic operation regarding the start-up and shutdown of cooking appliances. The use of lids allows for faster cooking of food and therefore less energy consumption.
  • Focus on local products: not only do you value your establishment to your customers, but you also reduce your costs by having good, varied and economical products that have grown close to your hotel.
  • Encourage cooks to reuse some food products that were previously discarded in part. It is possible to make broths, mashed potatoes, homemade jams, etc. with some vegetable drops, bark...
  • Offer innovative vegetable and pulse recipes. These are much less energy-intensive than meat, cost less and, moreover, are sought after by more and more customers.

In the laundry room

  • Maximize laundry and washing machines based on the options available to them: temperature, "economic" options, water filling, etc.
  • Limit the temperature level of the water supplied at the boiler to 55 or 60 degrees Celsius.
  • Perform regular maintenance of the boiler.
  • Burner speed: If the heating need is low, check the burner's running time. If the time is less than 6 minutes, when it's hot, contact your heating installer.
  • Hot water pumps and backup heaters must be set by a timer so that they do not operate between 22 and 6 hours.
 Once the first savings are realized and staff become familiar with new behaviours, it will then be easier for you to make larger changes. Also listen to your staff: hold regular meetings, whatever the season, to further improve everyone's approach and hear everyone's proposals. If you can invest a small budget in improving your facility, you can quickly save some extra energy by isolating hot water pipes to limit heat loss. Whether you have a heat pump, a gas boiler or a fuel boiler, an annual maintenance of your boiler, carried out by a professional, is mandatory. This allows, above all, to guarantee your safety but also to make you realize up to 10% savings on your energy consumption. If your installation is equipped with thermal radiators, it is strongly advised to purge them regularly. The best time to do this is the beginning of winter or if you hear suspicious noises in the facility. This action, very simple to carry out, will allow you to maximize the operation of your devices and avoid any overconsumption. Note, on a daily basis, in a table, your exact consumption of electricity, gas, fuel and water, based on the invoices received or by reading the figures on your meters. You will see, very quickly, any abnormal increase in your consumption. This allows you to take immediate action and avoid unnecessary costs. In order to further improve the energy efficiency of your establishment, the installation of modern and efficient equipment is essential. To do this, an EDF Enterprises expert can help you go further by:
  • Checking the quality of your hydraulic installation
  • Checking that the distribution system corresponds well to the uses of your establishment
  • Assessing the combustion efficiency of the boiler
  • Controlling the refrigerant of the air conditioning and its compliance with the legislation
  • Considering the value of setting up a hot water storage system in off-peak hours and/or a lighting control system for common areas
  • Etc...
 However, with these few tricks, it is already possible to achieve energy savings in the hotel industry in a substantial way without having to undertake major renovations and engage in heavy and significant investments. .
