Best Ideas 2022 features all the nominated entries submitted under ‘Submit your Idea’ category. All the entries consist of innovative solutions or propositions for an enterprise that champions the Sustainable Development Goals. They can be on the conceptual, planning, or start-up stage.
Energy efficient color-changing home
Explain your idea in details:
The thermochromic paint is a paint that changes color due to the changing temperature. You can easily find this phenomenon in the mood ring that changes color when we put it on our finger. We plan to implement this phenomenon on houses. And, we know that black absorbs all the light and white reflects it all. You might have felt this when you went out on a sizzling hot day wearing a black clothing. Your clothes are heated quickly, and you get hotter, while you are relatively cool in white clothing. Using these pieces of information, we thought of the color changing home. Think about it. If we paint the wall of a house in a thermochromic paint which turns white when it is hot and turns black when it is cold, what will happen? Lets look at the drawing of the thermochromic house. First, on hot days, sunlight will bounce off the white wall and wont be absorbed. So, the house can stay relatively cool. On the contrary, on cold days, the thermochromic paint will change into black, absorbing all the sunlight and making the house warm. This will lead to less usage of energy as well as environment conservation.
Expected impact of your idea on sustainable development
We think it will help in reducing energy consumption, leading to less pollution. It will help in achieving goal13, climate action. And by reducing the gap of energy usage, We hope it will decrease inequalities. The first impact is about climate action. We can expect these architecture technologies to be spread throughout the nations. Our idea will result in decreasing the whole worlds carbon dioxide emissions, and in the long term, these homes can delay global warming. This idea is a sustainable solution to the environment. Secondly, this idea has a large impact on reducing inequalities, the goal10 of UN SDGs. The warm and cooling systems of households cause lots of costs. And people from less income regions experience housing insecurities. However houses built based on our idea require far lower charge, and are sustainable in terms of energy efficiency. Of course, the main indicator for evaluating our success is the usage of electricity in households. So, our general target is to reduce energy consumption in warming and cooling. The exact value will differ by the region and the climate, but our first goal is to reduce overall energy consumption.
Plans for implementation and sustainability
We think this idea can be implemented as its way much easier to paint walls than construct a brand new sustainable house. Because we only need paint, it won't consume that much resources. And by reducing energy and electricity usage, there will be less environmental pollution and excessive consumption of resources. I think we can implement this idea by starting to paint the walls of public buildings and then expand the theronomic painting skills to normal households. We can cooperate with the start-up paint companies, working to produce eco-friendly paint resources. Our idea will be funded by the public through crowd-funding platforms including Indiegogo, Crowdy, or Microventures. While implementing, we will get advice from college chemistry and construction engineering professors. Also this is sustainable as it saves the first cost of building an energy efficient house. Compared to the other eco-friendly ideas like sunlight generation panels or building fully energy efficient houses, color-changing paint does not acquire that much cost. If our idea is implemented in real life, consumption of electricity as well as emission of CO2 in households would decrease. This can make the world atmosphere more clear and sustainable. People will paint their house with this thermochromic paint to reduce usage of energy used in heating and cooling their home. We hope that our idea would also help those who have little access to electricity.
We are JuYeon Park and Sooin Choi, and we were born in 2006. We are currently attending Seongnam Foreign Language High School in South Korea. After we learned about UN SDGs in Advanced English class, we started to develop ideas that are related to achieving them. We wanted to focus on climate action and equality, two of the goals that our class thought were most important.
