Question

can you me 5 entropy sources can be found in house and how to lessen those 5 entropy generation

*can you give me

Answer 1

Depending on where you live and the quality of insulation in your living space, the major sources of increasing entropy are the heating and air conditioning systems. With these efficiency matters a lot. If building your own house consider having a heat pump installed. Retrofitting one might be too expensive.

A heat pump can be used to both heat and to cool your house as needed, and they can work efficiently. Otherwise get furnaces and air conditioners that are well made and also among the most efficient available.

Next come lights and refrigerators/freezers. Use LED lighting as much as possible and use motion sensors to have lights turned off when no one is in the rooms. Where you place lights in a room also matters as does the reflectivity of the walls. Avoid dark colors.

The newest appliances are generally much more efficient than those made decades ago. It can be cost effective to replace something that is still working with a newer high efficiency model.

In the winter let as much sunlight come into your home as possible during daytime, but cover windows when it is dark to avoid radiating energy away that will require the use of more heating.

In the summer cover windows in daylight, except where outdoor lighting can substitute for electrical lighting. Uncover windows when it is dark, and if things cool off enough, open the windows.
