Received the ASEAN Energy Awards 2021 Thailand Energy Awards 2021 with an Excellence level in the Energy Conservation – Designated Building category. Environmental Management The Bank has been continuously improving energy efficiency in buildings under the Bank’s operational control since 2019. We focus on improving the efficiency of high-energy-intensity equipment such as air conditioning, cooling systems, lighting systems, and building engineering systems, which account for over 80% of the total electricity consumed. The Bank abides by the Energy Conservation Act (2007), where employees are strongly encouraged to responsibly consume resources such as electricity, water, and paper, through the promotion and awareness building of environmental conservation initiatives. ttb has established operational eco-efficiency targets to reduce 15% of the Bank’s electricity consumption and 10% of water consumption by 2026, compared to the 2019 base line. The following list below are key environmental performance for 2021: • In 2021, ttb overhauled the cooling and air conditioning systems to enhance energy efficiency in its buildings by using real-time analysis and automatic control of air handling unit.
