BMS (Building Management System) retrofitting promises energy savings, fault visibility, and remote operations, but only when scoped correctly for the building. Older Dubai towers vary widely in retrofit readiness.
What a basic retrofit covers
HVAC monitoring, time-of-day scheduling, alarm management, and basic energy logging. Even a minimal BMS overlay typically reduces annual energy 8-15% on poorly-scheduled buildings.
What deep retrofit adds
Demand-controlled ventilation, optimised chilled-water temperature reset, variable-speed drives on legacy fans and pumps, and integrated lighting control. Deep retrofits can reach 25-35% savings on aged buildings.
Where retrofits stall
Lack of accurate as-built drawings, undocumented control points, and legacy protocols (LonWorks, proprietary serial buses) extend timeline and budget. Site survey before quotation is essential.
BMS retrofit decision points
- Energy spend above AED 200k/year, retrofit usually pays back
- Recurring tenant complaints about comfort, BMS improves resolution
- No remote visibility today, operational risk improves immediately
- Document gaps, budget extra for survey and discovery
- Plan integration with metering for ongoing measurement
Why this matters
Energy savings from a good BMS retrofit compound annually; the operational visibility alone often justifies the project.
