Working with AI on the job

Working with AI

Where AI is starting to help

Imagine spending less time on tedious manual tasks and more time on high-impact technical design and problem-solving. AI isn't just for IT; it's rapidly changing how we manage and optimise our buildings. We're embracing these tools to make our engineers more efficient and our buildings smarter.

For a Senior Building Technology Engineer, AI can be a game-changer. It means less time sifting through endless data logs and more time designing the next generation of smart building solutions. We want you to be at the forefront of this, using AI to automate the mundane and elevate your technical impact.

Automated Fault Detection & Diagnostics (FDD)

AI-powered FDD platforms (like Clockworks or ICONICS) continuously analyse thousands of data points from the BAS. They'll spot hidden equipment faults, control loop errors, and energy waste that a human might miss. This shifts your focus from reactive troubleshooting to proactive optimisation, freeing you up from reviewing endless incident reports.

Predictive Maintenance Scheduling

Use AI models to analyse asset data from the IWMS (age, work order history, runtime) and sensor data from the BAS. This helps predict the remaining useful life of critical equipment (think chillers, boilers, RTUs). Instead of relying on fixed schedules or gut-feel, you'll have data-driven insights to plan maintenance and capital replacements more efficiently.

Technical Document & Specification Analysis

Use a large language model (LLM) to rapidly scan and summarise lengthy vendor proposals, technical specifications, and complex control sequences. It can flag non-standard terms, identify potential integration risks, and help you quickly compare technical capabilities against our requirements, saving you hours of reading.

Drafting Technical Reports & Communications

Use AI to draft initial versions of technical reports, project update emails, or even explanations of complex issues for non-technical stakeholders. Provide it with key data points and the desired tone (e.g., 'concise for a Director,' 'detailed for a technician'), and it generates a structured narrative, saving you significant writing time.
