With plans for continuous improvements in energy savings, Shangri-La Hotel, reviewed all sensors and upgraded them to increase energy savings. The hotel also reviewed all kitchen exhaust operation hours and incorporated variable speed drives into the system. It also checks, calibrates and ensures proper settings of thermostats to reduce wastages. One of the major initiatives the hotel undertook was to upgrade the lighting at the back-of-house areas. Shangri-La Hotel, upgraded the back-of-house lighting from the conventional Magnetic Ballast with T8 lighting to Electronic Ballast with T5 lighting. This change resulted in 25 per cent energy savings in terms of lighting and lighting in these areas was brighter by 10 per cent, thus improving working conditions for the staff.
