Modern infrastructure generates more data than ever before, but data alone doesn’t deliver value. What matters is how quickly and clearly it can be turned into action. Prefect’s Irus Optimiser, Reporter, and Investigator tools are designed to do exactly that.
Each has a distinct role, but together they simplify complex decision-making, helping teams see issues sooner, understand them faster, and act with confidence. Read on to understand the simple, practical effects of each solution and how they work together to create smarter, more efficient operations.
Complexity to Clarity
Reporter transforms millions of datapoints per day into clear, actionable reports, empowering compliance, tracking efficiency, and guiding strategic investment.
What It Does
- Generates bespoke reports across all dimensions:
- Site, Block, Floor, Flat, Room, or Circuit-level usage.
- Aggregation by day, week, month, or year.
- Environmental trends (e.g. temperature, humidity).
- Fault history and system performance.
- Supports benchmarking across buildings or sites for performance comparisons.
How It Performs
- Displays data in easy-to-read tables and spreadsheets with colour-coded outlier detection.
- Allows users to explore historical trends and zoom into specific timeframes.
- Exports reports in PDF, Excel, or CSV formats.
- Fully compatible with Tableau for deeper visualisation and analytics.
- Easily integrates with external systems for:
- Energy audits
- ESG/sustainability reporting
- Capital investment planning
Irus Reporter brings clarity and structure to complex data, helping organisations understand their estate at every level.
Easy criteria choice generates reports such as humidity (as above) over given time across blocks/floors/flats etc. The deep red colour shows clearly the cases of very high humidity.
Macro-Visibility to Micro-Control
Investigator is the diagnostic lens of the Irus platform, giving visibility across an entire estate, from a national overview right down to the performance of individual rooms.
Key Features
- Drills into granular system and environmental data:
- Heating output, occupancy, temperature, humidity, light, sound pressure, CO₂.
- Highlights deviations such as:
- Rooms not reaching target temperature.
- Active heating in unoccupied rooms.
- Persistently high humidity or condensation risk.
Flags issues
- Inefficient or faulty heating units.
- Poor insulation or cold air ingress.
- Occupant misuse (e.g. open windows during heating, blocked vents, supplementary heaters).
How It Performs
- Uses historical data, real-time feeds, and cross-room comparisons.
- Filters and will sort rooms by performance anomalies.
- Enables targeted troubleshooting, avoiding blanket interventions.
Irus Investigator is the precision tool providing detail of issues for every room, floor, and site, saving time, reducing energy waste, and supporting smarter maintenance.
Investigator provides a bird eye view of your property. Several observations are available including high users of water/energy, unoccupied rooms, noisy areas etc. In this case higher than usual levels of humidity are pin-pointed to a specific floor.
Data to Insight. Insight to Action.
Optimiser is the intelligent analytics layer of the Prefect Irus. While the core Irus platform automates heating based on occupancy and scheduling, Optimiser elevates building control by introducing smart diagnostics and actionable insight.
Core purpose: To optimise building performance by transforming data into actionable tasks. If operations teams do nothing other than act on the guidance delivered here they will see a substantial effect on energy and operational efficiency.
Key Capabilities
- Identifies inefficiencies across buildings.
- Prevents problems before they escalate.
- Reduces energy waste through fine-grained analysis.
- Supports proactive responses with data-led decisions.
How It Works
- Collects data from every ControlSensor, which including temperature, humidity, occupancy, light, sound pressure, and CO₂.
- Applies intelligent logic and thresholds to detect patterns and anomalies.
- Delivers insights through the intuitive dashboard, alerts, and reports.
- Equips building managers to triage issues efficiently and align with long-term sustainability goals.
Benefits
- Energy Efficiency: Detects and reduces hidden wastage.
- Maintenance: Flags faults before they lead to system failure.
- Sustainability: Aids ESG reporting and carbon reduction efforts.
- Budgeting: Informs financial planning and cost-saving decisions.
- Occupant Experience: Enhances comfort and reduces complaints.
Irus Optimiser is the analytical engine of Irus, bridging the gap between basic control and intelligent, insight-driven building performance.
Optimiser provides guidance to ‘quick-win’ solutions for rooms, equipment or users.
In this case there is an issue with power supply in a number of rooms; 14 rooms have unusual humidity levels; Action is required regarding high users of energy; Only a small proportion of rooms are using the standard heating profile; A large number of rooms are unoccupied.
This information equips maintenance and operation teams to take action to optimise building performance.
Combining Optimiser, Reporter, and Investigator, Prefect’s Irus platform delivers Control, Visibility and Intelligence. Transforms how estates are managed, optimised, and understood. From insight to action, it enables facilities managers to operate smarter, faster, and more sustainably.
