A Five-Tower Township Running Five Independent Building Automation Panels Isn’t Managed — It’s Monitored in Pieces

Think of a mixed-use township in Iloilo City that typically has separate residential, office, and retail towers, commissioned in phases. Each tower usually ends up running its own standalone building automation panel, from whatever mechanical contractor built it. That means the estate management office discovers a chiller plant fault or a stuck damper only when a tenant calls to complain — not when the sensor first drifted out of tolerance. As Infinite Systems Technology Corporation, we design township-scale building management systems around a single open-protocol backbone. A five-building estate should read as one dashboard, not five disconnected panels.

BACnet as the Township Integration Backbone

Township developments assembled in phases almost always end up with mixed-vendor mechanical and electrical equipment. One tower’s chillers come from one contractor, another tower’s AHUs from a different one entirely. We standardize the integration layer on BACnet, the open building automation protocol. It lets HVAC, lighting control, elevator status, and metering data from different equipment vendors report into a single Network Operations Center dashboard — without a full mechanical rip-and-replace to get there.

• Protocol layer: BACnet/IP backbone tying together per-tower automation panels into a single township-wide supervisory head-end
• Points integration: HVAC zone temperature and chiller plant status, lighting schedules and occupancy overrides, elevator status and fault alarms, and fire alarm panel status unified on one operator screen
• Alarm escalation: automated fault notification routed to the estate management office the moment a data point drifts out of tolerance, instead of waiting on a tenant complaint or a technician’s scheduled walk-through
• Phased commissioning: architecture designed to onboard each new tower as the township build-out continues, without re-engineering the supervisory layer each time

Energy Metrics and Submetering

Township-wide energy accountability starts with tenant and common-area submetering, feeding into the BMS energy dashboard. This gives estate management per-building and per-tenant consumption data, so they can benchmark performance and identify waste. A chiller plant running 15% above its baseline load factor is invisible on a utility bill. It’s immediately visible on a sub-metered BMS trend line. Various city developments are served by various electric power providers. We align demand-side metering and peak-load scheduling with the local provider’s rate structure — the same discipline we apply to Meralco-served developments in Metro Manila.

PD 1096 and BERDE-Aligned Compliance

Mechanical and electrical system design follows the National Building Code of the Philippines (PD 1096). For township developers pursuing green building certification, we structure BMS energy reporting to align with the BERDE (Building for Ecologically Responsive Design Excellence) framework. It’s administered by the Philippine Green Building Council. BERDE certification requires documented, ongoing energy performance data. A fragmented per-tower automation setup typically can’t produce that without manual reconciliation.

Fire Alarm Status on the Same Dashboard

A township-wide BMS is only complete if it includes life safety status alongside mechanical and energy data. Fire alarm panel status, elevator recall state, and stairwell pressurization fan status across every tower report into the same supervisory dashboard. That gives estate management a single point of visibility during an incident, instead of having to call each tower’s building engineer individually.

Coordinating with Tower-Level HVAC

The BMS supervisory layer is only as good as the mechanical systems reporting into it. We typically coordinate the BACnet integration directly with each tower’s commercial air conditioning installation from the outset. That means specifying BACnet-compatible controllers on new VRF and chiller plant equipment, so the tower is dashboard-ready the day it’s commissioned rather than retrofitted afterward.

Regional Deployment and Maintenance Coverage

Iloilo City and the broader Western Visayas region are serviced out of our Cebu Branch. Township developers and estate management teams scoping a BMS integration can reach the Visayas service desk at (0927) 333-4551. We’ll help align the BACnet points list, submetering scope, and phased commissioning sequence ahead of the next tower handover.
