Amarin Plaza

Amarin Plaza is a large building complex located in the Ratchaprasong district in Thailand’s capital, Bangkok. In a bid to further improve the originally implemented energy-saving measures, a decision was made to incorporate energy-saving technology from Japan, which is known as a leader in energy efficiency. Amarin Plaza successfully achieved energy-saving results far exceeding its targets by implementing an ESCO project to optimize the operation of its HVAC equipment while minimizing its investment.

Japanese energy-saving technology presented in a seminar makes an impression

With its record of maintaining a high economic growth rate for many years, Thailand is typical of industrial nations in Southeast Asia. Ratchaprasong Intersection in the heart of Bangkok is crowded with shopping malls and luxury hotels, and is in one of the busiest commercial districts in the country. The extensive 22-story Amarin Plaza building complex was completed in 1984. The first five stories are occupied by a shopping mall hosting some 300 business establishments, including clothing stores, variety shops, grocery stores, electric appliance stores, restaurants, and a food court. The sixth and higher floors are used as the offices of about 30 companies. Amarin Plaza is busy with 15,000 to 20,000 people visiting every day.

Rapid economic development in Thailand has resulted in a sharp rise in energy demand. Thus, energy conservation is a major issue throughout the country. Against this backdrop, Amarin Plaza has initiated various measures to tackle environmental problems and reduce energy costs for operating the building. It has already switched to LED lighting, improved the efficiency of its chillers, and is recycling water, for example. As Mr. Wisit Suthatheerarat, Assistant Vice President of Amarin Ratchaprasong Co., Ltd., recalls, “We had long been seeking effective energy-saving measures. One day, I attended a seminar held in Bangkok by the Global Environment Centre Foundation on energy-saving measures implemented for buildings in Bangkok. I was very impressed with the energy-saving technologies introduced in this seminar. I was particularly interested in the BEMS*1 system, which was not commonly used in Thailand at that time. So, I contacted Azbil Corporation, the company that was explaining energy-efficiency improvements in the seminar, to learn more.”

This case study was published in the 2015 Vol.3 issue of the azbil Group's corporate magazine, azbil.
