Jin Mao Tower, a mixed use complex, containing offices, convention space and hotel was built in 1999, and in 2013 became the tallest and the longest operated building in China to receive a LEED-EB:OM (Existing Buildings: Operations and Management) Gold Certification. Its high performance has been achieved with the assistance of a computerised energy management system, which has been in place since the building opened, and is integrated with the broader enterprise asset management (EAM) system.
Each month, building managers hold an energy consumption analysis meeting and clarify energy expenditure of each main equipment category, including water electricity and natural gas. The management team actively compares year-on-year and month-on-month consumption statistics, referencing the building automation system’s daily control log, to make informed decisions about where energy saving strategies should be implemented next. Specific action items are then drawn up for specific people, who take charge of implementing those measures.
