Annual Report 2020

Lighting Another major source of electricity consumption is provision of lighting in our properties and restaurants. The Group has started retrofitting the lighting system by LED-type lighting fixtures in common areas of Mira Place 1 and Mira Place Tower A since 2012, carried out phase by phase and integrated into the Asset Enhancement Packages. Retrofit of lighting system in the carpark area and sport zone on the ground floor was completed in 2017. The whole project brought approximately 4.8% reduction in electricity consumption this year, as compared with 2012. Other Green Facilities Enhancement in Electricity Consumption Variable Voltage Variable Frequency (“VVVF”) On-demand Controls for certain escalators in Mira Place 1 were installed in 2015 to optimize operation in different demand periods and reduce energy consumption. In addition, 2 transparent designed LED TV walls were installed at the Facade of Mira Place for advertising activities which allow natural sunlight to penetrate into the mall which greatly reduces electricity consumption for lighting. In 2019, most Primary Air Handling Units of HVAC system at Mira Place 1 were upgraded to on-demand control models, which operate and adjust ventilation based on carbon dioxide level detected in the areas for energy saving, while optimizing indoor air quality. Smart Use of Facilities Besides hardware enhancement of green facilities in our major business operations, the Group recognizes smart use of facilities is important for effective energy-saving. We have signed up for the “Energy Saving Charter” and maintained the temperature in open areas within our properties at 24˚C to 26˚C. We will temporarily suspend part of the lift services during non-peak hours. In Mira Moon, the chiller plant will be manually stopped when outside temperature drops below 13˚C. We installed motion sensors in hotel corridors and back-of-house areas, and set timer to control outdoor signage light. Energy Saving Measures on Facilities Enhancement As electricity consumption is the major cause for indirect greenhouse gas emissions, we have set Key Performance Indicators (“KPIs”) in our energy monitoring system to keep track of energy-saving performance. Results of the major facilities improvement after completion of installation are summarized below.
