Energy and backup optimisation for a 3-floor IT office

6,000 sq ft spread across 3 floors. 28 tonnes of air conditioning. A 20 kVA UPS and a 100 kVA DG set backing up lighting, computing, and a small on-site data centre — with ~5,000 units/month consumption, improper cooling distribution, and heat incidents triggering unplanned DG runs. SEnergy IoT delivered a 42-day turnaround with ~40% annual savings.

The challenge

  • Improper cooling distribution resulting in heat generation and minor incidents of fire.
  • Insufficient backup time, driving excessive dependency on the DG set.
  • Occasional DG failure, inefficient operation, and unknown consumption.
  • Suspected pilferage of diesel used for the backup DG set.
  • No visibility of per-area or per-equipment electricity consumption.

Objectives

  • Correct distribution imbalance across the entire building.
  • Optimise power backup and distribution.
  • Target the 19 air conditioning units to quantify cooling energy and surface imbalance.
  • Define conservation metrics and improve load balancing of the AC system.
  • Reduce downtime and improve load balancing of the power backup system.

What SEnergy IoT did

Site survey & instrumentation

A site survey identified the energy guzzlers. Smart energy meters and monitoring hardware were installed and networked to the SEnergy Cloud.

Distribution re-engineering

Overall distribution was re-engineered through optimal deployment and rewiring. Specification of distribution components and end equipment was corrected, as was the lay-out of the power-backup system.

Cooling re-engineering

Workspace layout altered to match space-tonnage index. Ventilation elements introduced to improve heat exchange and air circulation. More ACs added where tonnage was deficient.

42-day execution

The conservation project was executed within 42 days end-to-end — a planned, measured, instrumented turnaround from survey to go-live.

Results

  • Close to 40% annual energy savings.
  • UPS backup extended by 2 hours without additional batteries, cutting DG dependency.
  • 18-month projected ROI calculated from reduced energy bills alone.
  • Isolated and eliminated pilferage of diesel; per-unit production cost reduced.
  • Earth-fault alerts eliminated chances of fire mishaps.
  • Eliminated additional security deposit requirement imposed by the electricity supply company.
  • Enabled computing/workspace expansion without new CAPEX on power backup.
