A smart home is a technology-based house building, all electronic devices and systems in a smart home are connected to each other, making it easier for residents to control electronic devices from inside the house or remotely. The smart home concept is not only able to provide convenience and comfort for residents, but is also able to provide many good impacts on the environment, especially if the smart home also applies home automation technology. Home automation is a set of technologies that can be applied to house buildings to control lighting, air conditioning, and various other electronic devices in house buildings automatically using sensors. The following are some of the good environmental impacts if you apply the smart home concept to house buildings:

1. Electrical Energy Efficiency

The technology applied to the smart home allows the use of electronic objects more efficiently. Occupants can control the right time to turn on lights, water heaters, and air conditioners even when they are not in the house, so electronic items are only used when they are needed. Efficiency in the use of electrical energy certainly has a positive impact on the environment, because it can help reduce the greenhouse effect on the earth which is one of the reasons for the climate change in recent years.

2. Water Use Efficiency

In smart homes, home automation technology for sinks, toilet flushes, and automatic plant sprinklers is effective in saving water use to match what is needed. Auto-stop technology on the water faucet can also prevent leakage or excessive water use. Thus the use of clean water for household purposes becomes more efficient in homes that adopt the smart home concept when compared to homes that have not applied this concept.

3. Self Sufficient Home

Smart homes can also be equipped with various technologies that allow the house to be more self-sufficient. For example, by applying technology that allows residents to collect and treat rainwater, so that the water can be reused for several household purposes, such as washing cars or watering plants. In addition, technology to collect solar power using solar panels can also be applied to smart homes. The energy generated from solar power can then be used to run some of the electronic devices at home.
