Fault Detection & Diagnostics for Commercial Portfolios
Find Faults Fast. Prioritise What Matters.
Identify and resolve energy drains with Bueno’s Fault Detection & Diagnostics (FDD). We uncover issues that drain energy, increase costs, and compromise tenant comfort across your commercial real estate portfolio. Built to work seamlessly across diverse Building Management Systems (BMS), our FDD tools combine rule-based analytics with AI to detect, prioritise and recommend clear resolution paths for performance‑impacting issues.

Why Fault Detection Matters
Every building has hidden issues that traditional monitoring tools miss, from simultaneous heating and cooling to stuck valves and failed dampers. These faults silently waste thousands each month.
Bueno helps you:
- Detect issues early – before they impact NABERS or tenant satisfaction
- Prioritise by energy impact, tenant comfort, cost, or risk
- Resolve faults faster – through smart triage or recommended actions
- Track and validate resolution to close the loop
- Optimise workflow – across operations, FM teams and service contractors
Our platform also supports regional practices like condition-based maintenance (UK) and data-driven maintenance (AU and globally), helping clients align FDD with their preferred maintenance strategy.
Key Benefits
Data-driven maintenance improves maintenance regimes and reduces repair and maintenance costs
Using Fault Detection and Diagnostics tools enables your team to better manage time and contract costs, reducing OPEX.
Reduces time to service by identifying the root cause of issues
Breakdowns and fixes become costly and can negatively impact tenants if not quickly addressed. Sophisticated analytics identify the root cause faster.
Increases tenant satisfaction by pre-empting issues before they become complaints
You no longer have to wait for a tenant complaint. We provide you with data that identifies an issue before it impacts the tenant’s comfort.
Monitors and maximises equipment operation & lifecycle
Typically, capital planning is based only on manufacturer data sheets. Our platform provides data that can identify the actual performance of that equipment.
Provides access to near real-time data
Easy access to near real-time (every 5 min) data trends helps technicians and engineers to help inform their assessments, saving you time and money.
Obtains early insights into equipment issues and minimises response times
It costs more to repair equipment during a breakdown. With Fault Detection and Diagnostics data, you can be proactive and reduce unnecessary costs.
Monitors and improves tenant air quality and provides data for ratings
Indoor air quality of tenanted spaces is more important than ever. Being able to efficiently manage, demonstrate and share evidence of air-quality makes a meaningful impact on leases.
Maintains the condition of assets
Data-driven principles optimise equipment maintenance and prevent over-servicing.
Maintenance Performance reporting capabilities
Keep teams informed and accountable by auditing and reporting on the effectiveness of maintenance activity.
Built for Portfolio Performance
Unlike isolated alerts, Bueno’s FDD module provides a structured, portfolio-wide overview of faults across all assets. Actionable insights are tailored to reflect asset criticality, size, and usage profile—prioritising actions that deliver the greatest impact.
Portfolio View + Asset Detail
Get a high-level overview of all open issues across your buildings, then drill into specific faults, root causes, and asset performance history. Track historical trends and recurring fault patterns to support lifecycle management and maintenance planning.
Prioritised Insights
Faults are automatically ranked by cost, impact, and urgency. Our automations highlight high-value quick wins. Scorecard metrics help drive operational accountability—enabling teams to reduce maintenance spend and target critical issues.
Enhanced Collaboration
Share insights with service teams directly on the platform. Customise alerts by region, building type or team. Integrate with your existing CMMS, IWMS, and contractor systems to streamline workflows and improve first-time fix rates.

AI & Innovation in Fault Detection & Diagnostics
Artificial Intelligence is redefining how CRE portfolios detect and resolve system faults. Bueno’s AI models power deeper insights, faster fault triage, and smarter workflows that cut costs and improve performance.
Advanced Rule Library – Thousands of proven rules detect complex issues across all building systems.
AI-Driven Fault Triage – Machine learning pools and prioritises faults, reducing noise and guiding technicians to root causes.
Smart Dispatching – AI groups and ranks tasks for efficiency, improving first-time fix rates.
Continuous Learning – Models refine detection accuracy with every new fault, enhancing system reliability.
The result: fewer false alarms, faster resolutions, and more efficient operations across CRE portfolios.
Optimising Ratings Through Better Fault Management
Bueno’s Fault Detection & Diagnostics module directly supports sustainability and rating outcomes by reducing hidden inefficiencies that drag down performance. By resolving faults like simultaneous heating and cooling, stuck valves, or failed dampers, buildings run closer to design intent—improving energy intensity, thermal comfort, and equipment reliability.










Why Bueno Leads in FDD
Multi-layered Detection
Combines rule-based logic with ML pattern detection for deeper insights.
Criticality-Aware Analytics
Not all faults are equal - we prioritise what matters most. Issues are ranked based on impact to your business, across cost, comfort or compliance, so high-value items can be addressed first.
Fast Triage
Reduce manual work and enable faster resolutions with grouped faults and suggested actions.
Integrations That Work
Push FDD insights directly to your contractor or facilities workflow. Use our open APIs to embed within your existing platforms.
Designed for Scale
Track fault density, time to resolution, and operational health across every asset in your portfolio.
The Next Phase in Building Decarbonisation
Fault Detection & Diagnostics: Turning Data into Action
- Keep your assets performing at their best. With accurate, prioritised fault detection, you can address the issues that matter most, faster. Bueno’s FDD module identifies inefficiencies, equipment faults, and operational anomalies before they impact comfort, compliance, or cost. Intelligent insights create optimisation strategies that improve maintenance efficiency and reduce downtime.
Energy Management (Module 1)
Pinpoints where and how much energy is being consumed, identifying initial savings opportunities.
Fault Detection & Diagnostics (Module 2)
Applies the energy data (alongside BMS data) to identify what specific faults are causing wastage or impacting performance, and prioritises them for resolution. Essential for Data Driven Maintenance delivery.
Building Optimisation (Module 3)
Leverages both energy data and FDD insights with the power of AI to automatically adjust building controls for continuous peak performance. This closed-loop approach drives long-term optimisation outcomes at scale by resolving current issues and preventing future issues from arising.
