HVAC Monitoring System

Overview

An HVAC Monitoring System provides continuous, granular visibility into how heating, ventilation, and air-conditioning equipment is performing against design intent. Where a Building Management System (BMS) controls equipment to setpoints, an HVAC Monitoring layer observes whether those setpoints are being achieved, surfaces drift, and quantifies the energy and indoor-air-quality consequences. EcoXplore's HVAC Monitoring deploys on top of new or existing mechanical plant and feeds data into the PecStar iEMS analytics layer.

What we measure

• Supply and return air temperature, relative humidity, dew point
• Differential pressure across filters, coils, and air handling units
• Fan and pump status, runtime hours, vibration trend
• Chilled-water and condenser-water flow, supply and return temperatures, valve positions
• Per-AHU and per-zone energy consumption (electrical and thermal)
• Indoor air quality: CO2, PM2.5, PM10, VOC where required for WELL or RESET compliance

Outcomes

• Continuous commissioning reduces HVAC energy by 10 to 20 percent in typical commercial buildings
• Early detection of failed sensors, drifting calibrations, and mechanical degradation before they trigger occupant complaints
• Reporting against WELL, RESET, BCA Green Mark, and Singapore SS 554 indoor air quality benchmarks
• Extended equipment life through condition-based maintenance scheduling

Frequently Asked Questions

What does an HVAC Monitoring System measure?

Supply and return air temperature, relative humidity, differential pressure across filters and coils, fan and pump status, chilled-water and condenser-water flow, valve positions, and energy consumption per zone or air handling unit. The data feeds dashboards and analytics that surface drift from optimal setpoints.

How is HVAC Monitoring different from a BMS?

A BMS controls HVAC equipment based on setpoints and schedules. HVAC Monitoring observes and analyses how the equipment is actually performing against those setpoints. The monitoring layer often surfaces issues (failed sensors, drifting calibrations, mechanical degradation) that the BMS cannot see because its control loops simply respond to whatever the sensors report.

Does HVAC Monitoring help with indoor air quality compliance?

Yes. CO2, particulate (PM2.5, PM10), and VOC sensors integrate alongside thermal sensors so the platform reports against WELL, RESET, and Singapore SS 554 indoor air quality benchmarks.

What payback does HVAC Monitoring typically deliver?

Continuous commissioning programmes built on HVAC Monitoring data typically reduce HVAC energy by 10 to 20 percent in commercial buildings, with payback under 24 months. Avoided coil and filter failures (caught early through pressure-drop trending) extend equipment life and reduce reactive maintenance cost.
