The weather is always unpredictable. It can be warm sometimes and it can be cold sometimes. With global warming becoming more and more of an issue it has become even more unpredictable. But regardless of the weather we need to ensure that we stay warmer or colder depending on the situation. In a house we do this through use of climate control which takes a lot of energy to achieve which in turn is expensive. Coupled with resources slowly depleting in the world and restrictions due to the damage done to the atmosphere energy is becoming more and more expensive. Thus people are forced to look to alternate methods to achieve this.
One of the more ecofriendly methods available is through the method of residential defit in buildings. Depending on the weather heat will either travel inside through the walls during the warmer seasons or it will travel outside during the colder seasons. Heat travels this way in three ways conduction, convection and radiation. The application of this differs based on the situation. In the sense the way heat will travel in a given situation. Through the use of this method it will significantly stop that leakage of heat regardless of the way it happens.
Now residential insulation is done by putting materials that heat cant travel through between the gaps of the walls and such. That is to say the gap between the outside wall and the interior wall. They are also used in basement walls and on the roof if you have an attic in your house. Using this method has a lot of advantages. Moreover this is not limited to new houses being built you can do this to your house through renovation too.
To begin with as I mentioned earlier it is a very ecofriendly solution to the problem. Furthermore this is a much cheaper alternative. Of course as opposed to paying periodical energy bills this requires a significant capital investment but in my opinion in the long run this would prove to be the cheaper option and provide complete garage. Moving on you room temperature would be far more stable and it would not be prone to sudden drops or increase in the temperature. Hence through this method you would require less energy to keep your room temperature at a manageable level.
In addition to that leaving your house open to the elements can also cause structural damage in certain situations. That is to say extreme cold or heat would be bad for buildings so through this you ensure that the entire structure is at a balanced temperature at all times. So try this method and see and trust me you would not regret it.
