Exterior Paint Color And Home’s Temperature

When it is a hot summer time, we realize this is once again the time of year with increasing energy bill to a terrifying extent. We look for different alternatives to stay cool in our home. Turning off the HVAC 24 hours a day rises up the energy bill to the degree that we become worried about.

Color makes the difference

What we do not realize is the color of our home’s exterior makes a significant difference in the overall temperature of our home in the summer time.

We have known this since our childhood. Wearing a black t-shirt in the scorching sun entraps the heat. In contrasts, a white t-shirt repels the sun heat. In the same way, the dark colors trap a lot of heat from the sun whereas white and light-colored paint only trap the least of heat and hence less heat energy is transferred to the interior of your home.


Materials too!

However, there is another thing to be aware of. What your wall is made up of also makes the difference. For instance, if you have used strong and heavier materials like bricks and concrete, heat is less likely to pass through these materials. So there is only a very minimal difference in room temperatures of darkly painted homes and light color paint.

In contrast, lightweight materials are responsible for the greater transfer of heat energy in the home, inwards in the summer time and outwards in the winter. However, the insulators used in such lightweight materials minimize this heat transfer.

What about interior paint color?

The result is somehow same with the interior painting too. If you paint your interior with a dark color, it absorbs more light and needs more energy.  At the other side, light colored painted walls reflect more light and even supply of less lighting is enough.

Shall I change the paint to lighter colored one?

Yes, definitely you should.


This will save you money. In the long-term!

Will the saving be significant?

Certainly! Although your repainting cost takes time to give you return, it saves energy significantly by reducing heat energy by trapping 1/3rd less heat each year.

Paint your home with a light-colored paint and turn it into an energy-efficient home. It is not about just exterior, the interior walls, the roofs, and the floor also make the difference in the temperature and energy saving.

So start the saving today and you will make pretty significant saving at the end of the year.
