What You'll Learn
Use energy-efficient equipment and lighting
Restaurants use a significant amount of energy for lighting, so it is important to use energy-efficient lighting to reduce energy consumption and costs. One of the simplest and most effective ways to do this is to replace conventional incandescent bulbs with high-efficiency LED bulbs, which use about 75% less energy and last up to 10 times longer than incandescent bulbs. This can result in significant energy savings and reduced replacement costs. Additionally, upgrade your restaurant's exit signs to LED versions as they are always on, contributing to higher energy usage.
Another way to use energy-efficient lighting is by installing automatic dimming systems. These systems can adjust the amount of light each bulb emits based on the ambient lighting conditions, ensuring that energy is not wasted on brighter lights when natural light is sufficient. This not only saves energy but also creates a comfortable and adaptable lighting environment for customers.
When choosing equipment, it is important to consider the total cost of ownership, as the purchase price is often a small portion of this. ENERGY STAR-certified equipment, such as ventilating fans for bathrooms and ceilings, can save a significant amount of money each year. These fans use 70% less energy than standard models, and certified ceiling fan/light combination units are over 50% more efficient than conventional units.
Lastly, consider installing an Energy Management System (EMS). An EMS is designed to monitor and control a building's energy usage, including lighting and other electrical equipment. This technology can help you identify areas of energy waste and associated costs, allowing you to make data-driven decisions to optimise your energy usage and reduce costs.

Regularly clean and service equipment
Regular maintenance and servicing of equipment are crucial for optimising energy efficiency and reducing costs in a restaurant. Here are some detailed tips to help you get started:
Cleaning and Servicing Refrigeration Units
Refrigeration devices, such as walk-in coolers and freezers, contribute significantly to energy consumption in restaurants. To ensure these units run efficiently, it is important to clean the condenser coils at least twice a year. These coils are responsible for removing heat from the fridge, and when they become clogged with dust, they are less effective, causing the fridge to work harder to maintain food-safe temperatures.
Servicing Ventilation Systems
Ventilation systems, including HVAC (heating, ventilation, and air conditioning) equipment, are another area of focus. Regularly replace air filters, especially during heavy-use months like winter and summer. A dirty filter will slow down airflow, wasting energy. Additionally, consider adding extra panels to vent hoods in the kitchen. This will increase their ability to capture heat, reducing the energy needed for cooling.
Maintaining Kitchen Appliances
Kitchen appliances, such as ovens, grills, and deep fryers, consume a large amount of energy. It is important to follow the manufacturer's recommended maintenance schedule for these appliances. Regularly inspect oven gaskets and seals to prevent heat from escaping, and ensure proper functioning to avoid unnecessary energy loss.
Upgrading to Energy-Efficient Equipment
While maintaining and servicing equipment is essential, sometimes it may be necessary to upgrade to more energy-efficient models. Look for ENERGY STAR-certified equipment, which uses less energy and can lead to significant savings. For example, an energy-efficient dishwasher can save you money on utility bills and reduce water usage.
By regularly cleaning and servicing equipment and staying open to upgrades, your restaurant can make substantial energy savings and contribute to a greener environment.

Reduce water consumption
Reducing water consumption in a restaurant is not only beneficial for the environment but also helps lower operating costs. Here are some ways to reduce water consumption in your restaurant:
Use Low-Flow Spray Valves and Aerators
Replace your pre-rinse spray valves with low-flow spray valves that have lower gallons-per-minute (GPM) ratings. These valves are easy to replace and use much less water than older models. You can also install low-flow aerators or flow regulators in your hand-washing sinks to limit the amount of water flowing out of the faucet and lower the GPM.
Repair Leaky Faucets
A leaking faucet or pipe can lead to a significant amount of water waste over time. It is essential to fix leaky faucets immediately to prevent water and money from going down the drain. Many new faucet parts feature a cartridge design, making it a quick swap without the need for a plumber.
Fill Dishwashers Before Using
Dishwashers consume a lot of water, so it is best to operate them only when they are filled with dishes. Additionally, consider investing in energy-efficient ,
Install Water-Efficient Toilets
Toilets are frequently flushed by employees and customers, contributing to water usage. Installing water-efficient toilets can help reduce water consumption in your restaurant.
Lower Water Temperatures
Lowering the water temperature on your dish machine can also help conserve water. While the mandatory dishwashing temperature in the food service industry is around 140 degrees Fahrenheit, consider using lower temperatures when possible to save energy.
Implementing these water-saving practices can help your restaurant reduce its environmental impact and lower operating costs associated with water usage.

Implement a startup/shutdown plan for kitchen equipment
Restaurants use a significant amount of electricity for refrigeration, lighting, and cooling. Implementing a startup/shutdown plan for kitchen equipment can help to reduce energy consumption and lower utility costs.
To create a startup/shutdown plan, first observe when your equipment is being used the most. This will allow you to create a schedule for turning equipment on and off throughout the day. The goal is to only have appliances running when they are in use, preventing energy waste. For example, during downtime, you can turn off equipment such as the range or fryer and begin preheating again when business picks up.
In addition to creating a schedule, it is important to communicate the plan to your staff and ensure they understand the importance of following it. This may include training staff on the proper use of equipment and the impact of leaving idle equipment running.
Another way to ensure the success of your startup/shutdown plan is to implement smart control technology. This technology allows you to start up your appliances remotely, providing more flexibility and control over your energy usage.
By implementing a well-communicated and flexible startup/shutdown plan, you can reduce your restaurant's energy consumption, lower your utility costs, and contribute to a more sustainable environment.

Improve refrigeration efficiency
Refrigeration typically accounts for a smaller portion of restaurant energy costs, at about 6%. However, there are several ways to improve refrigeration efficiency and save on energy costs.
Firstly, regular maintenance and cleaning of refrigeration equipment are essential. Clean your refrigerator's cooling coils at least twice a year. The coils are responsible for removing heat from the fridge, and when they accumulate dust, they become less efficient. Therefore, regular cleaning ensures the refrigerator doesn't have to work harder to maintain the proper temperature.
Another way to improve efficiency is to ensure your refrigerators are tightly sealed. You can test this by placing a dollar bill between the seals and seeing if you can easily pull it out. If the seals are not tight, consider replacing them.
Additionally, avoid placing heating appliances near refrigerators. For example, having a stove next to a refrigerator will make the refrigerator work harder to maintain the desired temperature.
Finally, consider upgrading to more energy-efficient refrigeration equipment. While this may come with upfront costs, it will save you money in the long term. For example, purchasing ENERGY STAR-certified commercial food service equipment can cut kitchen utility costs without sacrificing features, quality, or style.
By implementing these strategies, you can improve the efficiency of your refrigeration systems, reduce energy consumption, and lower your restaurant's utility costs.
