Can the color of your house affect your energy bills

How can the colour of your house affect the temperature inside? Our society is increasingly becoming more energy conscious as well as financially aware. Every day I hear of people that try to use less. Whether they are hoping to be good for our environment or they just want to save some money. New appliances advertise excellent energy efficiency, automobiles are becoming more fuel efficient, some houses now have triple, even quadruple pane windows. All of this to save energy and in return fatten your wallet. We are jumping on the environmental bandwagon with our experiment. With all these more advanced products around to save you energy, we are testing something simple, something that everybody has inside their homes. The paint on your walls. You have probably learned about the warm and cold colours. For example, blue is considered a colder colour while orange is on the warmer side. But can this correlate to actual environmental temperature?
Who is in interested in these results? I would say the general population. Everybody is trying to become a little bit more eco-friendly. I do not think most people would repaint their house to save an amount of heat, unless the difference is quite considerable. However, people that are planning on remodeling their home or people considering building a special eco-friendly house might take our experiment into attention. Interior designers could also be quite interested in our experiment along with paint companies. Corporations that manufacture paint will be able to raise prices of the colours that save heat and advertise them as such. Interior designers could also help sell the products to their clients. Perhaps city planners might take our experiment into account as when they design public buildings they could use the colour that saves heat. The government might also be interested in our experiment because they could give rebates to people who decide to use the energy efficient colours in their house. The government would add paint to their current rebate program that includes appliances and energy efficient construction. And of course, environmentalists would be considerably interested in our experiment since they are the advocates of our environment. Although I have been focusing on saving money on heating bills, our experiment would also be useful in climates where people pay for cooling and not heating. In these climates, the colour that keeps a room the coolest would be popular. This would require less use of air conditioning and result in energy saving. However, this may not be for everybody. People that are concerned solely with aesthetics might take our experiment with a grain of salt. Also some people may not want to spend the money on paint upfront, and then go through the trouble of painting.
Even though our experiment is talking about houses, the results could be used in other fields. Something that comes off the top of my head, computers, might benefit greatly. Since computers need to be kept cool, the inside of an enclosure would be painted a colour that decreases the temperature. This not only would save energy because you would not need as much power delivered to the fans that cool the electrical components, it would also reduce noise as the fans would not spin as louder. Also, the computers performance would have room to increase. Another example of a place our experiment might apply to is the clothes dryer. My clothes dryer in my house is horribly inefficient. It does not produce a reasonable amount of heat, it takes forever to dry a small load, all while using enough power to run three newer energy efficient clothes dryers simultaneously. What if these new energy efficient clothes dryers could gain even more energy efficiency just by changing the colour inside the drum?
In this continuously more environment conscious world, our experiments results could not only impact the eco-friendly construction industry, but many other different areas and perhaps save people, governments, and corporations money.
