6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

BAS System Uptime Support
Your contribution to keeping our Building Automation Systems operational.
Target · 98% system uptime for assigned tasks

If a specific BAS controller you're monitoring goes offline, your prompt action (or escalation) helps restore it within the target window, contributing to overall uptime.

Critical Alarm Response Time
How quickly you respond to or escalate critical environmental alarms (e.g., temperature excursions, air quality alerts).
Target · <4 hours average response/escalation time

An alarm comes in about a server room overheating. You log it, check initial diagnostics, and escalate to the specialist within 30 minutes, preventing potential equipment damage.

Preventative Maintenance Task Completion
Completing scheduled checks and basic maintenance tasks for building technology systems.
Target · 100% completion of assigned tasks

You're assigned to check 10 specific sensor calibrations across 3 floors. You complete all 10 checks and document them by the deadline.

Data Logging Accuracy & Completeness
Ensuring data pulled from BAS or IWMS for analysis is accurate and complete, following established procedures.
Target · Fewer than 2 errors per 100 data points

When pulling a trend log for a specific air handling unit, all required data points are included, and the timestamps are correct, matching the system's record.

Adherence to Procedures
Following established protocols, checklists, and safety guidelines when working with building systems.
  • You consistently use the correct lockout/tagout procedures, follow troubleshooting guides step-by-step, and document your work exactly as required. Senior team members don't need to remind you about standard operating procedures.
Proactive Learning & Questioning
Actively seeking to understand how systems work, asking thoughtful questions, and taking notes to build your knowledge.
  • You'll ask 'why' something is done a certain way, not just 'how'. You come prepared with questions after reviewing documentation. You're quick to pick up new concepts and apply them, showing you're genuinely engaged in learning.
Effective Escalation & Communication
Clearly communicating issues and escalating problems to the right person at the right time.
  • When you hit a roadblock, you don't sit on it. You can clearly describe the problem, what you've tried, and what you need help with. Your emails are concise, and your verbal updates are to the point, saving everyone time.
Team Support & Collaboration
Being a helpful and reliable member of the building technology team.
  • You offer to help colleagues when your own tasks are complete. You're happy to pitch in on unexpected tasks and are generally seen as someone who contributes positively to the team's workload and morale. You're a good listener, too.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Learning New Technology

You'll be constantly exposed to new sensors, control systems, and software platforms. Every day is a chance to understand a bit more about how smart buildings operate.

You're excited when a new IoT sensor type is installed, and you're the first to ask how it integrates with the BAS, wanting to understand its data points and configuration.

Hands-On Problem Solving

You'll spend a good chunk of your time physically interacting with equipment, tracing wires, checking connections, and diagnosing issues on site. It's very practical work.

You enjoy the process of methodically troubleshooting why a specific VAV box isn't responding, checking the network, the controller, and the physical damper.

Contributing to a Functional Environment

Your work directly impacts people's comfort and safety. You'll see the immediate results of your efforts in a well-regulated building.

There's a quiet satisfaction in knowing that because you fixed a sensor, a whole floor is now at the perfect temperature, making people more productive.

What frustrates people
  • Dealing with legacy systems that are a pain to work with.
  • The constant need to follow strict procedures, even for 'obvious' fixes.
  • Having senior team members double-check all your work (it's for learning, but can feel a bit stifling).
  • The sheer volume of documentation you'll need to read and update.
  • Being on call for urgent issues, even outside of normal hours.
What this role does not give you
  • Significant autonomy or decision-making authority (not yet, anyway).
  • A purely strategic or conceptual role; this is very hands-on.
  • A predictable, 9-5 schedule every single day (emergencies happen).
  • The chance to build entirely new systems from scratch (you'll be supporting existing ones).

8Who you work with

This role directly supports the operational efficiency and comfort of our building portfolio. Your day-to-day work ensures that our expensive building technology investments are actually delivering value. You're helping to prevent small issues from becoming big, costly problems, which in turn keeps our operational costs down and tenant satisfaction up. Essentially, you're a critical part of making our buildings work as intended.

Inside the business
  • Building Technology Specialist
  • Senior Building Technology Engineer
  • Facilities Managers
  • Operations Teams
Outside the business
  • BAS Vendors (e.g., Johnson Controls, Siemens)
  • Service Contractors (HVAC, Electrical)
  • Building Occupants (indirectly, through comfort)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • A genuine interest in technology and how buildings work.
  • Basic computer literacy (Microsoft Office, email, web browsers).
  • Ability to follow detailed instructions accurately and consistently.
  • A methodical approach to problem-solving, even if it's just following a checklist.
  • A valid UK driving licence (as you'll be travelling between sites, typically).

10What to practise next

Where the job is going, and what to do about it starting this week.

Basic BAS Control Logic Interpretation

You'll move beyond just seeing what the BAS is doing to understanding why it's doing it. This means being able to read and interpret simple control sequences or block programming.

If/Then Statements · Setpoints & Schedules · Input/Output Mapping

  • This month: Ask your specialist to walk you through a simple control sequence for a fan coil unit.
  • Month 2: Try to explain a simple sequence of operation back to your specialist in your own words.
  • Month 3: With supervision, make a minor, pre-approved schedule adjustment in the BAS.
  • Month 4: Start to identify potential areas for minor optimisation in existing control logic.

Quick win: When you see a system behaving a certain way, try to connect it back to the programmed schedule or setpoint. 'Why is the fan off now?'

Operational Technology (OT) Network Awareness

Building systems are increasingly connected, forming their own networks. You'll need a basic understanding of how these networks work to troubleshoot connectivity issues and understand cybersecurity implications.

Network Basics · BACnet/IP · Cybersecurity Basics

  • This month: Learn what an IP address is and how to find one on a BAS controller.
  • Month 2: Ask about our OT network architecture – how are the BAS controllers connected?
  • Month 3: Understand the difference between the IT network and the OT network.
  • Month 4: Learn how to perform basic network connectivity tests (e.g., ping) on building devices.

Quick win: When you're on site, notice the network cables and switches. Ask your specialist to point out the 'BAS network' versus the 'corporate network'.

11Staying current once you are in

What people here do to keep up
  • Enrolling in online courses or workshops on building services fundamentals or basic electrical/mechanical principles.
  • Attending industry webinars on smart building technology and IoT to stay updated on trends.
  • Shadowing experienced technicians or engineers to learn practical skills and troubleshooting techniques.
  • Participating in internal training programmes on our specific BAS platforms and operational procedures.

Working with AI on the job

Working with AI

Where AI is starting to help

Imagine having a smart assistant that helps you diagnose problems faster, summarise complex manuals, and even draft your documentation. That's not science fiction anymore. Our team is leaning into AI to make the day-to-day work of building technology more efficient and, frankly, a lot less tedious.

Even at an entry level, AI can seriously boost your productivity. It's not about replacing you; it's about giving you superpowers. You'll be spending less time on the boring bits and more time on the interesting stuff – learning, troubleshooting, and getting hands-on with our systems. Here's a peek at how AI could transform your week:

Automated Fault Detection Support

AI-powered Fault Detection & Diagnostics (FDD) platforms constantly analyse BAS data. As a technician, you'll use these platforms to quickly pinpoint where an issue might be, rather than manually sifting through endless trend logs. It's like having a super-smart detective telling you exactly where to look for the problem.

Smart Manual Summaries

Technical manuals can be hundreds of pages long. Use an AI tool to instantly summarise key sections, find specific troubleshooting steps, or explain complex jargon in plain English. This means you spend less time reading and more time doing (and understanding!).

Documentation Drafts

After a site visit or a repair, use AI to help draft your work order notes, incident reports, or system change logs. Just provide the key facts, and the AI can structure it, ensuring all necessary details are captured and saving you a good chunk of writing time.

Basic Data Anomaly Spotting

When you're pulling trend data, AI can help you quickly spot unusual patterns or spikes that might indicate a problem. Instead of manually scanning graphs for hours, the AI can highlight potential issues for you to investigate further, making your data review much more effective.
