The Hidden Cost of Inefficient HVAC
Heating, Ventilation, and Air Conditioning (HVAC) systems are the backbone of modern buildings. HVAC Optimisation is often overlooked. From shopping centres and universities to office towers and hospitals, HVAC plays a critical role in ensuring occupant comfort, protecting equipment, and maintaining healthy indoor environments. Yet HVAC is also one of the largest consumers of energy in buildings, often accounting for 30–50% of total energy use.
When HVAC performance drifts or faults occur, the consequences go far beyond higher utility bills. Poorly optimised systems can:
-
Waste thousands in unnecessary energy use.
-
Accelerate wear and tear on plant equipment.
-
Create tenant complaints or customer discomfort.
-
Increase risk of product spoilage in sensitive industries.
-
Contribute to poor building ratings (NABERS, ENERGY STAR, LEED).
Common HVAC Issues That Analytics Can Resolve
Even the most sophisticated systems degrade without continuous monitoring. Analytics can identify and resolve problems such as:
Simultaneous heating and cooling – when heating and cooling run at the same time, wasting energy.
Stuck or faulty dampers/valves – preventing proper air distribution.
Sensor drift – inaccurate temperature or pressure readings leading to poor control decisions.
Short cycling in chillers or boilers – increasing energy use and equipment wear.
Excessive runtime – systems running after hours or at full load without demand.
Humidity or temperature imbalance – leading to comfort complaints or risks to sensitive equipment.
Analytics surfaces these issues early, before they escalate into breakdowns, complaints, or major repair costs.
Why Optimisation Matters Across Industries
The impact of HVAC inefficiency varies by sector:
Commercial Real Estate (CRE): Discomfort leads to tenant dissatisfaction, lower ratings, and higher operating costs.
Healthcare: Poor humidity or temperature control can jeopardise patient safety and compliance.
Grocery & Retail: Unstable store environments increase refrigeration strain, energy costs, and product spoilage.
Higher Education: Overheating or undercooling classrooms affects student comfort and learning outcomes.
Hospitality: Guest comfort is directly tied to brand reputation and repeat business.
In every industry, poorly performing HVAC is a hidden cost driver.
The Benefits of HVAC Analytics
Deploying an analytics platform to optimise HVAC delivers measurable value:
Energy Savings: Typically 15–25% reduction in HVAC energy use.
Reduced Maintenance Costs: Predictive fault detection minimises emergency callouts and extends equipment life.
Improved Comfort: Stable temperature and humidity improve tenant and customer satisfaction.
Stronger Ratings: Better NABERS, ENERGY STAR, and BREEAM outcomes through continuous optimisation.
Workforce Efficiency: Insights allow contractors to pool jobs, resolve faults faster, and reduce repeat callouts.
Not All HVAC Optimisation Is the Same
Many platforms claim to “optimise” HVAC, but true optimisation goes far beyond simple alarms or reactive monitoring. Key areas to look for include:
Depth of Rules & Analytics: Does the system only flag basic faults, or does it apply advanced rules to uncover hidden inefficiencies in chillers, boilers, and AHUs?
Integration Across Systems: Is optimisation siloed to HVAC alone, or does it consider interactions with lighting, refrigeration, and metering to prevent clashes?
Predictive Capabilities: Does the platform only react after a failure, or can it detect behavioural drift and predict issues before they escalate?
Actionable Outcomes: Are insights tied to cost, energy, and rating impacts, helping teams prioritise what matters most?
How Bueno Helps
Bueno’s platform applies over a decade of proven analytics expertise to HVAC optimisation. We go beyond setpoint checks with:
Over 130 FDD rules for HVAC, detecting everything from valve failures to control drift.
AI-driven predictive maintenance to flag deviations before failures occur.
Dynamic optimisation logic that balances HVAC with other building systems to reduce energy clashes.
Outcome-focused reporting linked directly to NABERS, ENERGY STAR, and operational savings.
This combination ensures HVAC isn’t just “monitored” — it’s actively optimised to deliver lasting efficiency, comfort, and rating improvements.
Real Results from HVAC Optimisation
Bueno’s analytics platform has shown that HVAC optimisation can reduce whole-building energy use by up to 20–30%, while cutting reactive maintenance costs. By integrating HVAC with other building systems like refrigeration, lighting, and metering, optimisation ensures that savings are sustainable across entire portfolios.
HVAC optimisation is not just about cutting energy. It’s about protecting long-term asset value, keeping people comfortable and safe, and enabling building owners to meet tightening compliance and sustainability targets.
