Effective ways to save energy in buildings today

Rethinking your energy consumption can do more than reduce your power bill.

Smart changes might increase your property value, assist you in B-corp certification and, of course, have a positive impact on the environment.

You don’t ned to do anything drastic to start saving energy. Installing energy efficient and improved appliances, upgrading your heating and cooling systems, or replacing old lights with LEDs will reduce your overall consumption. (LED technology has also proven to be safer and longer lasting compared to the older incandescent version).

Load studies

Another way to monitor and effectively save energy would be conducting a load study. Carried out by a certified electrical engineer, a load study analyses the power that flows around an electrical network to identify the best way to manage your energy.


Modern metering systems can also track energy use up to the second. Both metering systems and load studies help users engage actively with their energy use, understanding how much they are using and what actions are needed to save energy.

There are also more energy efficient ways to leverage the power of natural resources. Use sunlight to your advantage through solar-passive building orientation or sunlight harvesting. Co-ordinating artificial and natural sources of light through an effective lighting control system could trim your lighting costs by half.

Location and design

We encourage people to think of their surroundings when trying to optimise a temperature control system. The colour of exterior walls or the roof can act as a heat trap, as can concrete or bitumen around the building. Consider shading areas, or choosing lighter, reflective exterior colours.


Double glazing windows works to reduce energy transfer through glass. Alternately blinds, shutters or shade fins can help stabilise the temperature of a building without a large energy cost.

Even just opening your windows in the right arrangement can create cooling air flow that doesn’t rely on an air conditioner. You might consider installing a timer or considering installing fans which are inexpensive and cheaper to run than an air conditioner.

Lighting control systems

Lighting control systems are another option. They allow you to adjust lighting in a larger area than just one room or small area. It’s a convenient way of managing lighting energy use by turning off or dimming lights in spaces not being used.


Of course, there’s solar or even wind options. Renewable energy systems are more efficient and cheaper than ever, and solar battery systems allow businesses to move toward a self-sustainable system, selling off generated power onto the grid at peak evening times.
