Best Energy Saving Ideas for Hotels for Efficient Management

Best Energy Saving Ideas for Hotels for Efficient Management

Hotels consume energy through various activities, including heating and cooling rooms for guest comfort, lighting for both functional and aesthetic purposes, hot water usage, and other energy demands by guests themselves.

In this article, we will provide practical energy saving ideas for hotels to optimise their operation system costs without compromising guest comfort and satisfaction.

What is Hotel Energy Management in the Hotel Industry?

Hotel energy management involves monitoring and optimising the use of energy sources such as electricity, gas, and water, as well as ensuring the efficiency of energy-consuming equipment like heating, cooling systems, elevators, and laundry machines.

What Is The Amount of Hotel’s Energy Consumption?

Most hotels record energy consumption in the range of 200-400 kWh/m2/yr, with the average number falling between 305 and 330 kWh/m2/yr. According to a report (IMPIVA 1994), hotel energy consumption accounts for between 3% and 6% of the total operation costs.

Factors that affect the amount of energy consumed by a hotel include hotel size, category, services offered, occupancy, operational hours, climate, the age of the building, and the shape and location of the building. Practically, hotels providing more amenities like swimming pools, spas, restaurants, and bars are more likely to use more energy than smaller hotels with fewer services.

In addition, energy consumption in a hotel depends on the modernity of its HVAC and electrical systems.

Each square metre of a hotel room normally consumes about 0.55 kWh per day. Therefore, a hotel with 100 rooms in a standard size of 91 M could use approximately 50,000 kWh per day just for its hotel rooms.

What Factors Influence Energy Consumption in Hotels?

Below are significant factors that influence energy consumption in hotels:

1. Building

  • Size -The bigger the building, the more energy is consumed.
  • Shape – A hotel with all areas condensed in the same building will use less energy than one with a disparate property.
  • Age – A new building is supposed to have better insulation than an old one.
  • Materials – The material used to build the building is important in terms of its insulation and lighting.
  • Technical equipment – Efficient technical appliances can contribute to reducing energy consumption.

2. Hotel features

  • Category – More energy is needed for the higher hotel category (from 17.30kwhPAR for the economy to 89.35kwhPAR for luxury).
  • Facilities / Services – A hotel offering fewer services and facilities will consume less energy than a hotel with a range of services and facilities.

3. Location

  • Climate—The climate will decide how much air conditioning and heating are used. They are normally used more in hot and cold areas.
  • Local policies—Local energy policies affect prices and CO2 emissions, determining the type of energy, such as gas, electricity, nuclear, or wind.

4. Operations

  • Energy management in hospitality—The hotel policy for energy management is crucial in monitoring energy costs and setting up targets and best practices. It also involves all parties, from staff and investors to guests.
  • Occupancy – The more people stay in the building, the more energy is required.
  • Operational hours—Hotels typically operate 24/7, but energy costs can be lower during specific off-peak hours in some areas.

What are Energy Saving Ideas for Hotels?

Recommendations of the best energy saving tips for hotels include:

  • Nurturing culture of energy management
  • Saving energy on lighting system
  • Saving energy on HVAC system
  • Saving energy on water heating system
  • Saving energy on cooking system
  • Saving energy on hotel laundry
  • Saving energy on front office & lobby

Nurturing Culture of Energy Management

  • Train new employees on energy management: Integrate energy management training into new employee orientation to promote efficient energy use.
  • Track and report energy consumption to all employees: The engineering department should monitor energy usage and share data to identify best practices and highlight performance.
  • Create a culture of continuous improvement: Energy efficiency should become part of employee culture. Hotels can achieve that by boosting leadership and visibility, tracking energy use, and providing incentives.
Nurturing Culture of Energy Management

Saving Energy on Lighting System

  • Initiate a no-cost project first: It includes removing unnecessary lamps, turning off lights in unoccupied areas, installing switch plate covers to remind everyone to turn off lights, and keeping fixtures clean.
  • Conduct low-cost and low-investment projects: Retrofitting corridors with attractive fixtures that house compact fluorescent lamps can provide energy-efficient lighting while maintaining a pleasing ambience.
  • Replace incandescent lights with compact fluorescents: Standard incandescent bulbs are inefficient and have short lifespans, needing frequent replacement despite their low initial cost. Compact fluorescent lamps (CFLs) are energy-efficient spiral or U-shaped fluorescent bulbs that can directly replace incandescents in regular light fixtures.
  • Improve fluorescent light efficiency: Hotels can install lower-wattage or higher-efficiency lamps, replace old magnetic ballasts with electronic models, or do full-fixture retrofits. Simply replacing the oldest, most outdated fluorescent fixtures with brand-new high-efficiency models can provide an efficiency boost.
  • Train cleaning and security staff: The hotel-keeping staff should be trained to turn off all the lights, open the curtains after their morning service and close them in the evening.
  • Control outdoor lighting: The outside lighting should be fitted with timers, and different timing should be set for summer and winter months. Instead of all at once, it is recommended that each zone turn on 30 minutes apart and turn off 30 minutes apart.
  • Rewiring: Rewire and install additional switches or dimmers to make sure your present switches give you enough control to turn off unneeded lights.
  • Occupancy sensors: These devices turn lights on and off automatically in a space such as a restroom, storage area, or stockroom.
  • Use task lighting: Install desk lamps for close work at office desks and reception desks to put light appropriately.
  • Use daylighting: Using natural light during the day to supplement or even eliminate purchased light. It requires the installation of blinds or shades to control heat gain and glare, in combination with rewiring and installation of switches.

Saving Energy on the HVAC system

  • Keep systems off when unoccupied: When no one is occupying an area, it is the best time to save energy.
  • Use ceiling fans: The fans create an evaporative cooling effect by pulling air over the skin, making guests feel comfortable at higher temperatures in the summer.
  • Put locking covers on thermostats: Make a reasonable setting and cover thermostats in public areas with tamper-proof covers. Consider replacing them with ones that hold a fixed setting.
  • Inspect and repair duct leaks: The duct system in air distribution systems works as part of your energy check-up. Maintain it regularly, fix any broken joints and other leaks, and ensure it is insulated through unconditioned space.
  • Replace/clean filters and coils: Filters and coils should be cleaned and changed regularly to ensure the mechanical system interacts most directly with the environment it impacts.
  • Chiller coil temperature reset: To save chiller energy, increase or decrease the coil temperatures according to outdoor air temperatures.
  • Condenser water temperature reset: Cooler condenser water temperature from the cooling towers can help increase the chiller’s efficiency. Water is given to the condenser side of the chiller as cool as possible, following the manufacturer’s recommendations and the continued capacity to reach interior temperature set points.
  • Adjust temperature set points: Each section of the hotel expects certain interior temperatures depending on seasonal climatic temperature conditions. Setting appropriate seasonal set points can help save energy while still maximising guest satisfaction.
  • Buy energy-efficient equipment: Laws require manufacturers of HVAC equipment and appliances to achieve minimum efficiency levels. You can check with your local utility or HVAC Service Company to know the requirements in your area.
  • Heat exchangers: While bringing fresh air in and stealing air out of a hotel, heat exchangers can exchange 50% to 70% of the energy between the two air streams.
  • Consider heat pumps: Heat pumps move heat from one place to another to provide heating or cooling.

Saving Energy on Water Heating System

  • Reduce water temperature settings: Water heater settings are often much higher than the actual demand, so lowering them will help save considerable energy.
  • Reduce heat loss: Install blankets to minimise heat loss, as well as insulate the exposed hot water piping.
  • Label faucet: Post labels asking people of your conservation effort to “Please turn off the water.” In addition, you can install self-closing faucets to push down for 10 to 15 seconds of water flow.
  • Reduce the amount of time the system operates: Time clocks while the facility is closed or during peak electric demand hours can save much energy for your hotel.
  • Maintain the system: Have a service technician check and clean the fuel-fired systems once a year to ensure they burn properly.

Saving Energy on Cooking System

  • General cooking energy saving: During slower times, power down individual cooking equipment or dial it back to an idling state instead of keeping it at full blast. For gas units, watch for those beautiful blue flames—they’re the sign of an optimal gas-to-air ratio and clean burners. And don’t overload those hard-working ovens and ranges beyond their recommended capacity.
  • Fryer’s equipment: Draining and straining the oil or checking fat levels frequently can save oil and preserve food quality.
  • Griddle equipment: Stop preheating when the griddle surface reaches the correct cooking temperature and only heat the necessary sections. In addition, clean the griddle frequently and always re-season while scraping the cooking surface between production intervals.
  • Broiler equipment: Control the preheating of a broiler at an appropriate time and temperature while loading it to maximum capacity to achieve optimal efficiency. Also, frequently washed grates can contribute to carbonising grease, hinder heat, lower cooking efficiency, and mar food quality.
  • Oven equipment: Insulation levels and quality of oven design will decide its energy efficiency for hotels.
  • Steamer equipment: Well-insulated steamer ovens are quick to preheat thanks to their high heat transfer characteristics of steam. They need less energy to stay up to the temperature and reduce heat loss in the kitchen.
  • Kitchen refrigeration: Refrigeration systems are “On” all the time, and they consume electricity. Therefore, even small amounts of energy lost by poorly maintained refrigeration can add up to substantial costs over time.
  • Kitchen ventilation: To conserve energy in kitchen ventilation, ensure the exhaust hood captures as much cooking effluent as possible, consider installing variable-speed exhaust fans to adjust airflow based on demand, and maximise hood size for optimal efficiency. Regular rebalancing of the system is also recommended to maintain peak performance over time.

Saving Energy on Hotel Laundry

  • Move the lights to different switches working for different corners of the laundry. This will help the hotel switch off the lights when not required.
  • Clean lamps and light fixtures once a month to optimise their lighting levels.
  • Clean and wash walls, floors, and ceilings to facilitate the reflection of lights.
  • Check and record the water consumption daily to find any wastage.
  • Consider employing cold water detergents.
  • Check all steam line values to make sure there are no leaks that can shut off steam to any machine not in use, keeping the steam supply main open.
  • Make the Engineering Department’s preventive maintenance schedule of all laundry equipment to ensure timely compliance.

Saving Energy in Front Office & Lobby

  • During low occupancy, the front office can rent the rooms by virtue of the location.
  • During summertime, areas on the north and east sides of the building are cooler than the other areas.
  • Corner rooms that expose two sides get warmer.
  • Avoid rooms close to the heat source if possible.
  • Block as far as possible the wings of individual floors when occupancy is not high.
  • The rooms without rent should have air conditioning switched off. Set the air conditioning to start 30 minutes before the guests move in.
