The project activities mainly focus on improving energy efficiency in heating, ventilation, and air conditioning (HVAC) systems, lighting systems, and elevators. At the same time, the project also implemented other energy-saving measures, including efficient lighting systems, natural ventilation, and building energy management systems. The project activity also installed off grid self provided rooftop solar photovoltaic panels, which will also contribute to a portion of the emission reduction. In addition, geothermal sources are also used to supply hot/chilled water to buildings.
