Pearl Building Bangkok - The concept behind the design of the Pearl Building Bangkok is energy efficiency. The unique design of the building was to create an inspirational & iconic shape to resemble an oval pearl. Already a landmark in Bangkok, part of its fame is that on special occasions such as New Years or Valentines, the multicolored LED lighting on its shell is illuminated and puts on a light show. Better yet, it is an energy-saving green building that uses insulated low iron glass to reduce outside heat while allowing natural light to enter which reduces the amount of electricity required for lighting and air conditioning which reduces electricity consumption by 60 per cent. The building also has a water-recycling treatment system reducing water usage reducing water usage by 40 per cent. The building was designed by Palmer & Turner architectural firm.
