Apart from being a symbol of a country, the construction of high-rise skyscrapers rises by various things, such as the increasingly expensive land price, the increasing population, and the problem of urbanization.

Urbanization is the shift of population from rural to urban areas. Due to the urbanization process, a country’s population accumulates in urban areas, making the population density in urban areas large. Indonesia itself ranks fifth as the country with the largest urban population globally.

According to Urban Growth 2005 – 2010 data, the urban population in Indonesia reached 114.1 million people, with Jakarta as the most populous city. In line with these data, Jakarta is also listed as the 8th city globally with the highest number of tall buildings.

The number of buildings with a height of more than 150 meters in Jakarta reaches 128 buildings and 45 buildings with more than 200 meters. The number of buildings plugged in in Jakarta raises new problems, especially if the building does not apply the concept of green building. Large power consumption, environmental damage, declining quality of workers are some of the consequences that are present.

Meanwhile, besides addressing climate and power consumption problems, there are several other benefits of implementing smart green buildings. According to World GBC data, a Green Building is a healthy building. This healthy building will provide good lighting, increase employee productivity by 18%, improve student test scores up to 5 -14% (for schools building), 10%-25% improvement in memory and mental function to up to 11% improvement in better ventilation.

Apart from the numbers above, there are also opportunities to collaborate with other companies by having a green building. Some companies today only want to work with companies that have a concern for the environment.

Presenting a green building is not only by building basic infrastructure. It requires the support of sensors connected to the internet or internet of things (IoT) solutions. These sensors will absorb various information about power usage and productivity occupancy.

IoT devices in smart buildings will learn and process the data contained in the building to then issue helpful information for building owners/managers. IoT devices will track and tell how a building consumes power per day, which floors absorb the most energy, and which devices. IoT will tell the points of inefficiency in the building.

IoT devices in the building also provide recommendations to reduce the cost of these utilities. Soon, IoT devices can inform the condition of another building surrounding, connecting one to another.

In the IBM report, several IoT devices can help companies achieve the above goals. For energy efficiency, the IoT device needed is a lighting sensor that can turn on and off by reading the surrounding conditions or adjusting to a specific time.

In addition, there are sensors installed in heating, ventilation, and air conditioning systems, which so far consume the most significant power consumption in a building, and automation of building nuances.

Then for efficient use of water, smart buildings need to have sensors for monitoring pipe water leaks, automatic sprinklers, and water quality monitoring devices.

Finally, to provide comfort and health in a building, it must have an air quality monitoring sensor. So, with the above benefits, will you start developing green buildings?
