Key FEATURES

Decarbonise With Certainty: From Daily Operation to Net Zero

Lock in real operational performance across the whole building lifecycle. Powered by building physics and managed by performance experts, IES Live pinpoints the upgrades that matter most and maximises energy, carbon, capital and operational savings, at every stage.

Lower Operational Costs Today

Start saving before you spend. Understand historic, current and optimal performance, find where energy is wasted, and act on it now.

Quick energy, cost and carbon wins with little to no capital outlay
Simple BMS control adjustments that pay back fast
Expert recommendations with ROI shown directly in your dashboards
Clear energy, carbon and comfort visualisation
10–20% savings with minimal capital spend

Evidence-Based Retrofit Decisions

Invest with confidence. Build a physics-backed decarbonisation pathway and see the impact of every retrofit option before you commit capital.

Trusted engineering-grade data to de-risk every investment
A detailed net-zero decarbonisation pathway, created by expert consultants
ROI tailored to your business KPIs and outcomes
Clear visualisation of predicted retrofit scenario impacts
Whole-life carbon balanced alongside energy, comfort and cost
20–70% savings with capital spend

Ongoing Evaluation & Verification

Prove your retrofit projects deliver as expected. Track ongoing verified savings against your plan, ensuring the results you promised are the results you can evidence.

Live ROI tracking and savings quantification against the plan
Monitoring-based commissioning of implemented improvements
Live performance-gap quantification and visualisation
Auditable evidence of compliance with your net-zero commitments
Feedback loops that connect finance, sustainability and facilities teams

Continuous Operational Monitoring

Keep it that way. Catch performance drift the moment it starts, so hard-won savings don't quietly leak away.

Physics-based monitoring against how your building should perform, not last year's bill
Track energy use against real occupancy to measure efficiency, not just consumption
Early detection of drift, faults and creeping inefficiency
Stops the building falling back into wasteful operation
Locks in your 20–70% savings for the long term

Frequently Asked Questions

What is IES Live?

IES Live is a building decarbonisation and energy management platform powered by building physics and managed by performance experts. It bridges the gap between AECO consultants and building owners, delivering reliable data for investment-ready decarbonisation decisions and ongoing operational energy management.
Who is IES Live designed for?

IES Live is designed for owners and operators of existing buildings looking to reduce energy use, cut carbon, and make confident retrofit investment decisions — supported by expert consultants throughout the process.
How much can IES Live save on energy and carbon?

IES Live can deliver operational energy savings ranging from 10–20% through low capital interventions up to 70% with deeper retrofit measures — all tracked and verified over time.
How does IES Live support retrofit decision making?
Can IES Live verify that improvements are actually working?

Yes. IES Live continuously monitors and tracks performance against expected outcomes, quantifying real savings over time and preventing buildings from falling back into inefficient operation through measurement, verification and evaluation against a simulated baseline.
What is a decarbonisation pathway and does IES Live provide one?

A decarbonisation pathway is a structured, evidence-based plan for reducing a building's carbon emissions over time. IES Live provides a detailed pathway for your building, covering net-zero investment planning, whole life carbon, and ongoing monitoring against targets.
How does IES Live help with compliance and reporting?

IES Live provides verified performance data and clear visualisation tools that help building owners evidence compliance with net-zero commitments and create feedback loops between finance, sustainability, and facilities teams.
