The Working Room Data Center in Serpong stands as a landmark of geometric architecture in the urban hub of Tangerang, an industrial and manufacturing hub outside of Jakarta. It’s futuristic angles, red lights and spiked roof all signify that the building is different, but beyond its exterior, the office for the telkosigma IT company is also designed to be resource-efficient and green. The office building conserves up to 75% in water use with features such as a rainwater harvesting system that covers the entire roof and a black water treatment and recycling system. To save energy, low-E glass technology minimizes heat radiation from the sunlight that streams in from the east and south sides of the building. The pattern on the building’s façade serves a dual function of not only symbolizing the company’s work in the data sector, but also reducing the window to wall ratio, which limits energy usage. Paired with external shading devices and energy-efficient air conditioning, these features keep the building cool in Jakarta’s tropical climate. The building is owned by PT Sigma Cipta Caraka, which is an IT services and solutions provider that is mindful of environmental problems, making EDGE certification a logical fulfillment of the company’s philosophy.
The building’s green features were added by the developer, PT. PP, at very little additional cost and are expected to be recovered through utility savings in less than four months, as utility bills are projected to be half of what are typical of a conventional building. PT. PP has more than six decades of experience in the Indonesian construction sector and is committed to building sustainably. The company has developed embassies, hospitals, homes, offices and more throughout Indonesia. The Working Room Data Center in Serpong has received a preliminary EDGE certificate from the Green Building Council Indonesia.
