Guidance and tools to fix problems and improve performance.

Compare building performance against targets and peers.

Real-time AI-powered FDD to maximize building performance

• FDD collects and cleans existing utility, building, and equipment data to create a single unified portfolio-level dataset.
• Its deep data capture consolidates all critical infrastructure, including energy and water meters, sub-meters, elevators, HVAC equipment, temperature sensors, lighting and more.

FDD

​

​

​

​

1. COLLECT

• Using sophisticated AI-powered algorithms, FDD continuously tracks your building's performance in real-time.
• It analyzes patterns, identifies anomalies, and detects inefficiencies across all connected building systems, ensuring no operational issue goes unnoticed.

​

​

​

2. MONITOR

Real-time continuous monitoring of all critical plant and equipment

Monitoring is underpinned by an ever-growing database of thousands of proprietary algorithms developed by expert mechanical, mechatronic and electrical engineers. Picking up faults, anomalies and opportunities to optimize.

Advanced algorithms give you the power of a thousand engineers

​

​

2. MONITOR

• FDD doesn't just identify issues - it provides intelligent, actionable recommendations that are easy for anyone to implement.
• From simple equipment adjustments to complex operational changes, a centralized workflow allows teams to collaborate and fix issues quickly before tenants and customers are affected.

Core software features

​

Utility monitoring

​

​

​

​

Use Meters to uncover your building’s electricity, gas and water usage at both a high and granular level.

​

• Perform trend, sub-meter and load profile analysis.
• Identify areas of excessive or abnormal consumption.
• Visualise trends using various chart formats and export data and charts.

Equipment monitoring

​

​

​

​

Monitor all critical equipment in real-time, ensuring every building operates at its most efficient performance level.

​

• View equipment uptime and identify low performing equipment across your portfolio.
• Review alerts to understand root-cause of faults, steps to resolution and timeline for maintenance.
• Use equipment score to guide strategic capex planning and maintenance decisions.

IEQ monitoring

​

​

​

​

Ensure you maintain optimal conditions and a high IE rating by tracking temperature and relative humidity in real-time.

​

• AI-powered algorithms continually monitor every temperature sensor to detect and resolve faults or anomalies.
• Continuous monitoring ensures tenant comfort, IE ratings improvement and portfolio benchmarking.
• Tag VIP floors or NABERS IE sensors for priority action

AFDD Rules Engine

​

​

​

​

AI-powered automated fault detection & diagnosis (AFDD) Rules Engine contains thousands of pre-configured algorithms to detect critical issues.

​

• Examples include overnight operation, energy wastage, safety and compliance, tenant comfort, and lift operation.
• Each identified issue includes a recommended solution and a data trend history.
• The software’s algorithms are all built by highly qualified building engineers to avoid noisy alerts and false positives.

Alert notifications

​

​

​

​

Customisable alert notifications ensure critical issues get sent to the right person at the right time.

​

• Your team will know instantly when critical or major equipment failure occurs in the building.
• Site teams can fix issues fast, helping to avoid major issues that could impact lease agreements.
• Set up targeted notifications to your favourite apps like Slack or Teams about the equipment that is most important to you.

Digital workflow

​

​

​

​

Intuitive mobile workflow tool where asset teams and vendors can raise tasks, track progress and maintain a complete digital history of activity.

​

• Site teams can assign to issues to contractors in one click and monitor to progress to rapid rectification.
• Saves contractors significant time as photos and updates can be easily added via their mobile device
• Easily manage collaboration on activities across multiple stakeholders and buildings.

Sustainability ratings

​

​

​

​

View and share all your ratings in one place and save time by capturing historical and current rating metrics.

​

• Track ratings movements at an asset and weighted average portfolio level.
• Know exactly when your next rating expiry date is approaching and plan accordingly.
• Compatible with all major ratings - NABERS, BREEAM, Energy Star, etc.

Dashboards and reports

​

​

​

​

Dashboards and reports enable Asset and Operation teams to review and benchmark key portfolio and building metrics at anytime.

​

• Dashboards cover utility consumption, equipment KPI’s, contractor activity, IEQ, team performance, lift performance and more.
• Detailed reports enable deep insight into portfolio performance over time, which supports capital planning and resource allocation.
• All data is also accessible via our enterprise grade API.

Data-driven maintenance

​

1. Initial integration

Introduction of analytics without maintenance contracts aligned.

​

2. Contract evolution

Analytics with realigned maintenance contracts to comply with the principles of data-driven maintenance.

​

3. Mastery and refinement

Ongoing regime after clearing R&M and optimisation backlog.

Data-driven maintenance

Harness the transformative power of AI, FDD and analytics to align maintenance with industry best-practice

“By leveraging the capabilities of the AFDD platform it is anticipated that overlap with the mechanical scope of maintenance services can be minimised and as a result maintenance providers can service an increased number of assets with fewer technicians.”

​

“Further to this, it is anticipated that the quality and type of work will shift, freeing up some of the more scheduled tasks and routine checks, so that the technician can focus on resolving issues or carrying out repairs, leading to a higher performing building in terms of comfort and energy efficiency.”
