Green Kitchen Solutions - Energy Efficiencies

Updated: Feb 8

Contrary to common belief, adopting green practices in your commercial kitchen is not the budget-buster often perceived to be.

In fact, opting for green kitchen solutions like energy-efficient appliances and sustainable layouts can be a strategic financial move. Going green has significant long-term advantages, including lowered operational costs, enhanced public perception, and a positive environmental impact.

Energy Consumption in Commercial Kitchens 

As your bills keep increasing, the lion's share of your monthly expenses goes to lighting, heating, and cooking. Although it might seem that there's nothing you can do about it, viable solutions do exist. 

Take a look at the average energy consumption in commercial kitchens by appliances: 

  • Refrigeration: 70 kWh (41%) 

  • Fryers: 11 kWh (13%) 

  • Ovens: 35 kWh (12%) 

  • Bain Maries: 27 kWh (9%) 

  • Grills: 37 kWh (12%) 

Let's take refrigeration, for example. Not only does it increase significantly your expenses, but it also makes you a contributor to carbon emissions. Refrigeration in the food industry is responsible for 3.2% of the UK's total emissions. You're paying good money to sustain climate change without even knowing it. It's not something you want to be known for when 45% of British consumers are influenced on how to spend their money by a venue's dedication to sustainability. 

Green kitchen solutions and energy efficiency are no longer mere choices but imperative for the food industry. 

Conserve Energy with Key Energy-Efficient Equipment

Green Refrigeration Solutions 

  • Energy star-rated refrigerators and freezers meet stringent energy efficiency guidelines, reducing operating costs and environmental impact. 

  • Proper maintenance practices like cleaning coils and checking door seals ensure optimal performance and extend the lifespan of the equipment. 

Energy-Efficient Kitchen Appliances 

  • Induction cooktops use magnetic fields for precise temperature control and fast adjustments. This method enhances cooking efficiency and minimises energy loss. 

  • Convection ovens circulate hot air for even heating, reducing preheating and cooking times. Moreover, a convection oven's advanced temperature control features can make it 20% more energy efficient than a standard oven. 

  • Electric grills with high-performance capabilities decrease grilling time, thus conserving energy, and stay operable at a minimum setting when not in active use. 

  • High-efficiency fryers speed up cooking times, translating into energy savings over the long run. 

Green Lighting and HVAC Systems 

  • LED light solutions for commercial kitchens are energy-efficient, have a longer lifespan, and emit less heat, contributing to a cooler kitchen space. 

  • Motion sensor lighting in key kitchen areas means less energy is used during periods of low activity. 

  • Upgraded HVAC systems allow precise temperature control, ensuring that heating, ventilation, and air conditioning operate efficiently.  

Optimised Water Use for Energy Efficiency 

  • Upgrading to high-efficiency dishwashers with low-flow nozzles and sensors can significantly reduce energy and water consumption. 

  • Minimising water waste during steam-based cooking or cleaning will optimise the energy used to heat the water. 

  • Energy-efficient water heaters and insulated hot water pipes can reduce heat loss during water delivery. 

Start with an Energy-Efficient Commercial Kitchen Design  

The first step towards your green commercial kitchen is a well-organised layout for optimised workflows. This way, kitchen staff can move seamlessly between different workstations and save energy by reducing unnecessary actions and expediting tasks. 

You can increase energy efficiency further through the strategic arrangement of kitchen appliances. Specifically, it's crucial to maintain a considerable distance between cold storage equipment and oven and cooking stations. Failure to do so would necessitate refrigerators compensating for additional heat. Also, grouping appliances and equipment with similar heating requirements enhances efficiency by allowing shared exhaust systems and ventilation hoods. 

How to Save Energy with Proper Insulation and Ventilation 

When it comes to insulation and ventilation, you want to focus on three key areas: 

  • Innovative materials and equipment 

  • Proper maintenance practices 

  • Staff-related energy conservation measures 

Green and innovative insulation materials contribute to a more effective thermal envelope, reducing heat transfer through walls and minimising the strain on heating and cooling systems. Similarly, installing ventilation equipment with demand-controlled features enhances precision in airflow management. These innovative solutions create comfort and significantly reduce energy usage. 

To maintain these gained advantages in the long run, you must regularly check for wear, tear, or damage and promptly address any issues that arise. Routine maintenance guarantees the optimal performance of systems, preventing potential inefficiencies and ensuring that airflow remains in sync with the kitchen's needs.  

Last but not least, you want to educate kitchen staff on energy-conscious behaviours, such as minimising unnecessary openings of doors and windows. A culture of awareness and responsibility contributes to energy-efficient operations, improving kitchen productivity and eco-friendliness.
