Energy is extremely precious and given the economic and environmental state of affairs, the need to conserve it is even greater than ever before.

For those who are operating heavy energy usage devices like a cold room, the need to conserve energy is also about limiting overhead expenses along with minimizing the relative carbon footprint.

Often the problem is though most of us are aware of the heavy energy consumption by a cold room; often the challenge is knowing how to arrest that. It makes both business and environmental sense to cut down on electricity consumption.

The breakup indicates that energy bills and the associated overheads can make up for nearly 30% of the cost.

Now if you add up the maths and are an astute business person, you will agree that this is not an easy expense.

So here are 15 interesting ways to control your carbon footprint and overheads:

1) Check the refrigerant quality

Refrigeration System Types

If you have a cold room with a leaking refrigerant, it affects the cost ratio in every possible way. First and foremost a leaking refrigerant posts a potential environmental hazard and could be health-threatening too.

This will also impact the efficiency of the cold room and will need you to make incremental expenses to fill it up at a close frequency.

When the cold room is running on an inadequate amount of refrigerant, it can also damage the overall functioning and performance of the cold room.

This can then start consuming a lot more energy and your bills may spike up suddenly.

2) Make sure you pay attention to lighting

Often this is the most ignored aspect but results in maximum overhead expenses. Think about the lighting in the cold room and take a practical call.

Make an exact calculation of the lights that you need and the material that you choose. It is also extremely important to go for energy-efficient lighting devices.

That way the incremental cost every month can be reduced to a large extent. Often you don’t realize it but the electricity charges make up for nearly 80% of the overhead expenses. Thoughtful choice of lighting can help reduce this to a large extent.

3) Do not crimp on safety


When you are looking to save overhead costs and limit carbon footprint, safety becomes a predominant pre-condition.

By observing basic safety measures in a cold room, you don’t just make sure that you are providing a safe work condition but at the same time cutting down a lot of related overhead expenses like health cost, material damage and replacement expenses.

So, using a safe cold room also translates into monthly savings under a lot of heads and relative maintenance expenses reined to a large extent as a result of this.

4) Use environment-friendly refrigerant


The choice of refrigerant is very important. The market is full of various options. Some are CFCs, HCFCs and even chlorine-free HFCs.

There are many natural refrigerants like carbon dioxide and ammonia and what you choose to use can have a lot of bearing on the environmental impact it creates.

Additionally, if you do not make appropriate choices and the refrigerant is not compatible with the cold room pipes and materials, it can result in corrosion of the material and possible bleaching too.

So make sure that you assess the compatibility of the refrigerant with your cold room before making a choice.

5) Check the door design

If the overhead costs of your cold room have shot up or higher than average, it is time to check the design of the door and way it fits in.

One of the biggest reasons for additional energy use is the risk of leaking depending on the door design or fit.

Make sure the cold room door fits properly and the cooling process proceeds the normal way.

If additional energy is not used to cool it down, it will also yield a relatively better value result in terms of the energy bills.

Additionally, the maintenance charges will also come down significantly, and the efficiency of the cold room also gets a booster.

6) Improve insulation

The need to improve insulation is also important for the same reason. Without appropriate insulation, energy usage can reach disproportionate levels and at the same time, the performance and the efficiency of the cold room suffer too.

The overall performance can dip and the maintenance costs may sho
