The project
A commercial office building of approximately 30,048 m² in Cheras, Kuala Lumpur, developed by Sunway Integrated Properties. First certified in 2019 and renewed to GreenRE Silver in 2022.
What the assessment found
Air-conditioning systems scored 17.21 points. The reported operational system efficiency was 0.72 kW/RT against an average cooling load of 405.02 RT, with a chilled-water temperature differential of 5.84°C. The reported 2021 Energy Efficiency Index was 95.29 kWh/m²/year.
Those are the numbers that matter on an operating office tower, and they are measured rather than modelled. That is the difference between a building designed to be efficient and one that is being run efficiently.
Artificial lighting took the full 12 of 12, with daylighting in common areas, car park ventilation and common-area ventilation each contributing 2 points. Efficient lifts and escalators scored 3, with VVVF drives, standby and sleep functions and motion sensing.
Water conservation picked up points for usage monitoring, drought-tolerant planting and cooling tower management, with the reported cycles of concentration at approximately 7.6.
Greenery took the full 6 of 6 on Green Plot Ratio, and noise compliance a full 2 of 2.
Outcome
GreenRE Silver retained at 77.25 points.
Indoor air quality was tested under DOSH ICOP IAQ 2010 alongside occupant surveys and lighting and noise assessments: the operational discipline that keeps a renewal straightforward rather than remedial.
Assessment result
What this building scored, credit by credit
Most consultancies publish a rating and a photograph. This is the assessment itself: awarded against available, criterion by criterion, so you can see where the points came from and where they were left on the table. Assessed under GreenRE Non-Residential Building, renewal assessment, final result 77.25 points, GreenRE Silver retained (renewed 2022, first certified 2019).
