Energy effectiveness in our home can be done with proper isolation. Heating and cooling are top two items with the most energy wasting; it counts for even 57% of total household wasted energy. To keep the comfort in our home, we should keep the heating on particular level. During the winter we should increase the temperature, and during the summer the opposite. That can be achieved by two ways:
- Increasing/decreasing of the heating/cooling intensity
- Decreasing of the energy loss in winter and energy gain in summer through the external walls, doors and windows
Both ways are good for energy effectiveness. At the first case, thermal comfort is easily achieved but it’s too expensive. During winter everyone can turn on the heating for extra hours, or during the summer can put the air conditioner turned on whole day, but that’s not the point for energy saving. As a consequence the price we need to pay for this approach can be too expensive. If we choose the second approach (decreasing the energy loss/gain through walls, doors and windows) we will have lower bills.
First, we should examine the heating/cooling nature. The heating process represents passing heat energy from one item with higher temperature to another item with lower temperature. The source that emits heat, transfers the energy to the next item. The humans take heat through the air. When we heat some space, we heat the air in it, and through the air we are heating ourselves. Also with this process we are heating the external walls in a given room, through where the heat from the internal air is transmitted to the external air. In that way we lose energy.
In this context, we were already speaking for saving energy by installing quality windows with low emissions glass in this blog post: “Reduce your bills; reduce payday loans–use low emissions glass!”
