How to Improve Your Home’s Energy Efficiency

One of the greatest movements in the 21st century is sustainability and energy efficiency. As more humans populate the earth and consume more electricity, the cost of energy is also increasing. Little minute things we do for our home’s can affect our air conditioning and electric bills. In this article we will provide you with a run down on areas that you can look into to ensure that you are making the most out of your monthly bills at home.

Utilize Smart Technology (IOT)

With technological advancements today, every single device can be connected and controlled on the cloud. Consider investing in connecting all your devices to a central platform so that you can monitor the electric usage and turn things off where you are not at home or using them. Smart devices such as a a Nest thermostat can also help you automatically adjust the temperature of your A/C if it gets too cold or it detects that you have left the room. This helps prevent wastage of energy and your bills to be reduced.

Purchasing Appliances That are Energy Efficient

In Singapore, all appliances are labeled with energy efficiency ratings. Ensure that when you are in the market for an appliance such as a fridge or an air conditioner, that you look for appliances that have three white ticks. This denotes that the appliance is energy efficient and the labels even tell you the amount that you will save each year. These savings could be significant if you add up the amount of years that you would be using the appliance.

Install blinds and treat your windows

If your home is facing the afternoon sun, consider installing blinds to block out the heat and burning your apartment up, and even better, treat your windows to a coating of reflective film to block out UV rays. These blinds will reduce heat intake in the walls and flooring of your home and would reduce the cooling required in the evenings when you decide to run your A/C before bed.

Partition Rooms When Running the A/C

When you switch on your air conditioning, always ensure that you close your doors and if your room is too large, you may even partition it up with a movable room divider to keep the cool air circulating within the area that you are in. Closing doors are the more effective option while movable room dividers are less effective as there will be more leakage of cool air to the outside of the room.

Look towards independent energy companies

In 2019, the Open Electricity Market became fully effective. Home owners have the ability to choose who they would like to buy their electric from and have savings of up to 30% compared to SP services.

If you are in the middle of a home renovation, you can design your home with sustainability in mind to make sure that you are using materials that do not retain heat. Additionally, creating your floor plan to allow natural light to flow into your home would help you save on lighting bills in the day.

Switch off appliances from the switch

At the core of it, every parent has taught and reminded their child to switch off all appliances and lights if you are not using it, and it is applicable up to this day. Save electricity by switching off appliances you do not need or use so that it does not use “Standby” power that trickles every second of the day.

With these steps, you would be able to save a significant amount of money on your electric bills and feel good about yourself as you are conserving the world’s resources for future generations to come.
