Amari Watergate Bangkok

The Amari Watergate Bangkok hotel is located in a downtown area called Pratunam in Bangkok, the capital city of Thailand. The hotel was selected for a model energy conservation project proposed by a Japanese company. It has implemented a series of energy-saving measures, including a BEMS, and as a result of optimal air-conditioning and heat source equipment operation it has saved a large amount of energy. The system implemented at the hotel has also made it possible to visualize energy performance. The hotel now receives much attention as a leading example of energy efficiency in Thailand.

Chosen for a Japanese company’s model project, Amari Watergate Bangkok redoubled its energy-saving measures

Amari Watergate Bangkok, a five-star hotel, opened in 1994 in Thailand’s capital city of Bangkok, and is conspicuously situated in a 34-story modern building on Petchburi Road, which is lined with shopping malls. In addition to the view of the city from its luxurious rooms, the hotel provides various facilities such as restaurants and a fitness center. Many foreigners who visit Bangkok for sightseeing and business purposes choose to stay at the hotel.

Today, Thailand is faced with a skyrocketing demand for electricity as its economy continues to grow. It is imperative for the nation to find ways to use energy efficiently, and so Amari Watergate Bangkok is also making efforts to save energy, with both cost reduction and environmental policy in mind. “We have always taken measures like adding thermal insulation film to the hotel windows and introducing a water recycling system and cleaning system for the air-conditioning cooling tower,” explains Udom Srisanit, engineering director at the hotel.

In 2009, the Chugoku Electric Power Co., Inc. (Chugoku EPCO), a Japanese firm, drew up an energy-saving plan for Thailand in cooperation with the Metropolitan Electricity Authority (MEA), a Thai company supplying power to the capital city area, and submitted the plan to a competitive subsidy program arranged by NEDO.*1 The plan was accepted, and after examining the possibilities for implementation, Chugoku EPCO selected Amari Watergate Bangkok as its Thai recipient company because of its enthusiasm for energy efficiency. The hotel was judged to have the potential for large energy savings.

NEDO is pushing forward with its project of supporting the implementation of energy- saving measures in foreign nations in order to promote Japanese “green” technologies around the world. For participants in the project, NEDO entirely covers the equipment costs necessary for implementation, with the facility owner paying only the construction and renovation costs. Therefore, the plan was very attractive to Amari Watergate Bangkok.
