Building Energy Services

Take control of your building’s assets, reducing your energy-related maintenance and operating costs.

Hong Kong’s buildings account for about 90% of the city’s electricity usage. Over 60% of our carbon emissions are attributable to generating electricity for our buildings.  Improving the energy efficiency of your building, therefore, goes a long way toward Hong Kong’s 2030+ target.
Across all types of buildings from offices, local authorities, and universities to retail outlets and airports, energy management, carbon reporting, and green building compliance are becoming top priorities.
