Sustainability Report 2017

55 Electricity Consumption Since electricity is crucial for SET operations, SET has implemented several energy-saving initiatives, including using double glazed windows to reduce heat transmission, setting air conditioner temperature in line with the temperature outside the office buildings, installing motion light sensor switches and using LED light bulbs. Moreover, SET installed solar panels on the roof of the parking building and reduced grid power consumption by 65,795 kWh, which saved THB 328,974 in 2017. Digitization In the process of becoming a digital exchange, SET not only keeps up with technological changes but also promotes the utilization of IT equipment to improve resource efficiency and reduce energy consumption. In 2017, the following implementation and activities were carried out: • SET streamlined its enterprise processes, resulting in the reduction of paper use by 20%. • SET constantly developed tasks and services via electronic systems to lessen process steps and paper documents in securities registrar and shareholder meeting system and shareholder registration systems. • SET supported administrative work, including meeting room reservation, leave record, medical reimbursement and training registration, via the SET Enterprise application, reducing paper consumption in approval processes and promoting user convenience. • SET used eco-friendly electronic equipment such as portable laptop computers which save up to 10 times energy compared to desktop computers, multifunction printers which require users to use employee ID cards in printing to reduce paper and ink consumption from unnecessary or unintentional print orders, replacing exhibition boards and PR banners with digital signage and QR codes. • SET reduced environmental impact of commuting by providing online training activities and seminars, such as online Opportunity Day sessions and Investor Classroom seminars, facilitating investors in accessing SET activities anytime, anywhere. • SET promoted bike commuting and the use of mass transit and eco-cars. SET also procured corporate cars with hybrid-technology to save gas. In 2017, the corporate cars used up 6,367 liters of gas, a decrease of 8% from 2016. Water Management SET continues to reduce water consumption and manages to use water-saving sanitaryware, including faucets and pipes, and technology to improve the efficiency of the piping and wastewater treatment systems. In 2017, SET consumed a total of 53,105 cubic meters of water. About 90% out of 8,030 cubic meters of wastewater was treated and reused in building maintenance. SET has focused on energy and resource efficiency. Significantly, the SET building has been certified by the Leadership in Energy and Environmental Design (LEED), a widely-accepted green building certification program, at the Gold level. Resource Management Target of electricity consumption reduction in 2018 % 3 In 2017, there were more activities, including First Trading Day ceremonies and marketing promotion activities, held at the SET building, compared to the previous year. The total electricity consumption reached 897,300 kWh, showing a slight increase of 1.12% from 2016. (302-1), (302-3) (302-5) (302-4)
