Discover’s top energy-savings tips for businesses so that your profits aren’t being eaten up by your energy bills.

The impending climate change crisis and the continuous rise of gas and electricity prices have forced many businesses across Ireland to re-elevate their energy usage in the workplace. 

Luckily lowering your business's energy consumption and carbon footprint doesn’t have to cost you money.

In fact, according to the Sustainable Energy Authority of Ireland (SEAI), businesses could save up to 10% on their energy bills by implementing no-cost and low-cost energy efficiency measures alone. 

To discover simple energy-saving practices your business can adopt today check out our list of tips below. 

Adopt energy-saving practices at work

One of the simplest and most important ways for a business to lower its energy usage is by creating and adopting an energy-saving culture at work. 

As a team draw up a list of guidelines which outline different energy-saving measures everyone can participate in such as turning off the lights when you leave a room or closing windows before you put the heating on. 

If everyone is playing their part to reduce their energy consumption at work, you will all help lower your workplace’s carbon footprint and energy bills - a benefit that your business’s finance department will surely appreciate!

Lighting tips 

According to the SEAI, 40% of a building’s energy use is attributed to lighting, therefore it is essential that your lighting fixtures and practices keep energy-saving goals in mind. 

Take advantage of natural light

Don’t let your business overlook the power of natural light. 

Move obstructions that are blocking windows or natural streams of light into the office. You can place desks in areas where natural light hits, which will reduce your company’s reliance on artificial light and create a more pleasant working environment. 

Use LED light bulbs 

Did you know low-energy light bulbs (LED) use around 80-90% less electricity than a standard bulb? And they are designed to last up to 10 times longer!

By using LED bulbs in the workplace, you are conserving energy and money without having to sacrifice the quality and level of light in your office. 

Turn off the lights 

Make sure to turn off the lights in rooms when they aren’t being used and at the end of the work day. (Of course, this is safety dependent but there is no need to have the lights in the meeting room on if no one is occupying it.)

You can also install light sensors and timers to ensure the lights turn off automatically at the end of the working day. 

Heating tips

Dress appropriately for the temperature

Wearing the right clothes to work will mean you don’t have to put on personal heating appliances unnecessarily. 

During the colder months wear warm woollen-based clothing like jumpers and cardigans to the office, instead of automatically turning on or up the radiator. 

In comparison, during the hotter weather, consider wearing lighter fabrics like linen to keep you cool, rather than putting on the air conditioning. 

If you don’t believe in the energy-saving ability of dressing for the right temperature, then look to Spain. Its Prime Minister, Pedro Sánchez, recently encouraged other ministers and office workers to stop wearing ties to work to keep cool in the workplace and save electricity.  

Ensure thermostats are set correctly

Did you know that every time you increase your heating by 1°C you increase your heating costs by approximately 8%? Therefore, it's important to make sure your thermostat is set at the correct temperature. 

Set the heating in offices to 19°C and cooling at 24°C or higher. In areas with high physical activity such as corridors and storerooms, the temperature can be set lower than 19°C.

Make use of heating timers

Setting timers will ensure you are not wasting energy by heating or cooling down your office outside of working hours. 

Use a fan 

Fans use up less electricity and are cheaper to run than air conditioners. 

This is because fans circulate the natural air in your home, while air conditioners generate cold air by extracting moisture from the air. If you are looking to cool down a small space and it isn’t very humid out then turning on the fan is the right option for you. However, on humid days and for large spaces air conditioners are better suited.

Before switching on the air conditioning or heating

Before switching on the air conditioning (AC), consider opening a window to cool down your office or turning on a fan. These simple measures often get overlooked but they will save you energy and money. 

However, if it is still too warm in the office, then it may be time to stick on the air conditioning but make sure all the windows in the office are closed so that the cold air is able to circulate properly. 

The same goes for heating up the office. Before you go to turn on the heating, make sure all the windows are closed, put on a jumper or put on a mini heater beside your desk. 

During the winter these simple measures may not suffice, so if you’re putting on the heating ensure that all windows are closed, so the heat does not escape out the window. 

Tackle draughts

Repair any holes and gaps around walls, windows, skylights and doors. These holes will let cold air in and will let hot air escape out of the building, meaning that you are essentially throwing money away when you put the heating on. 

Other ways to tackle draughts include getting door draught excluders and investing in double-glazed windows or roof insulation. 

Equipment tips

Invest in energy-efficient equipment 

When buying equipment for the office check the energy-efficiency rating label on products.

Products with a high energy rating are designed to consume less energy, be longer-lasting and be more durable than older models.

It is worth paying that little bit extra for more energy-efficient equipment as they will save you money in the long run and are better for the environment.

Turn off non-essential equipment 

Instead of leaving computers, projectors, printers and photocopiers on standby mode when they aren’t being used, turn them off. This will ensure you aren’t wasting energy or shortening the lifespan of these machines. 

According to IT experts, a typical PC and monitor combination can consume around 200 watts when it is left idle which can cost your business over 200 a year! Increase the number of PCs and monitors by 20 and you can only imagine how much leaving these items idle is costing your business annually.

Use the eco-mode setting on appliances

Select the power-saving mode available on your business's equipment to reduce its energy consumption. This is especially important for items that must be left on 24/7. 

For example, by putting your photocopier on the power-saving mode, the amount of energy your photocopier uses is reduced by 92%.

You should also set up the sleep mode function on all the company computers so they will consume less energy when they aren’t in use.

Energy-efficiency grants and finance supports for businesses 

Hiring a consultant to create a roadmap to lower your business's carbon footprint or investing in energy-efficient equipment or building products like insulation or solar panels can be expensive.

To ensure your business has the means to become more energy efficient SEAI and Enterprise Ireland have created grants available to support these endeavours. For instance, there are currently grants of up to €162,500 available for businesses looking to install solar panels and the infrastructure associated with them for non-residential commercial and public sector buildings on the SEAI website.

To learn more about the different grant options for your business, check out their websites. 

If your business is struggling to cover the costs of its energy bills, you may be able to avail of the Temporary Business Energy Support Scheme (TBESS). If your business has experienced an increase of 30% or more in its electricity and/or natural gas average unit price, then you may be able to claim:

  • 40% of the increases in your September 2022 to February 2023 energy bills
  • 50% of the increase in your March 2023 to July 2023 energy bills 

You can find out if you are eligible for the scheme by visiting the website.
