Rooftop Solartop

July 31, 2014

Heating systems are one of the most expensive energy consuming processes, especially in developing countries. Reducing dependence on traditional energy sources and maximizing use of natural energy, such as the sun, proves to be a more sustainable choice.

 

To reduce dependence on traditional energy sources, in 2011, Shangri-La Hotel, Bangkok turned an idle rooftop overlooking the famous Chao Phraya River into a bed of solar panels spanning a space of over 900 square meters (about 9,687 square feet).  By the end of the year, the solar energy heated 25 million liters (over 6 million gallons) of water, sufficient for the 802 guestrooms of the Shangri-La Wing and the Krungthep Wing at the hotel.

 

By contributing to a clean and green environment, the solar water heating system yields many advantages. In terms of economic and financial achievement, the system allows the hotel to conserve non-renewable fuel and reduce dependence on oil. Fewer pollutants, such as carbon dioxide, sulphates and nitrates, are released into the environment, directly impacting the prevention of the greenhouse effect.

 

“With the implementation of the in-house solar water heating system, the hotel has put a stop to 435 metric tons (about 95,900 pounds) of CO2 emissions annually," said Mr. Kieran Twomey, who was the general manager at the time of the installation. "It may look like a tiny step but hopefully, this tiny step makes a difference in the world.”
