ActiveTrim is the predictive optimisation engine within Attain Platform. It learns how your building works, then uses machine learning to nudge it toward higher efficiency — fully automatically.
It continuously balances demand, comfort and system performance, making thousands of small adjustments that add up to serious energy savings.
Weather shifts. Occupancy moves. Equipment ages. Tenant patterns change. Yet many buildings still run on fixed schedules and rigid control strategies written for conditions that no longer exist.
ActiveTrim replaces that static logic with a live, evolving understanding of the building. It learns how systems respond, anticipates what the space will need and keeps operation closer to real demand.
Tracks millions of data points
Continuously processes live information from connected systems to understand performance in real time.
Connects across MEP systems
Brings HVAC, lighting, ventilation, metering and other operational systems into one intelligent layer.
Learns how the building behaves
Builds an evolving model of how systems respond to weather, occupancy, schedules and use.
Anticipates demand
Uses predictive intelligence to prepare systems before conditions change, rather than reacting after the fact.
Adapts continuously
Refines control strategies as the building, equipment and operating patterns evolve.
ActiveTrim looks beyond headline consumption. It analyses how energy is distributed, when systems run, what conditions they create and whether that operation is genuinely needed.
Electricity
Benchmark loads, identify unnecessary demand and understand where consumption is building up.
HVAC
Match heating, cooling and ventilation more closely to live environmental and occupancy needs.
Gas
Reduce avoidable plant operation and improve the relationship between heat demand and system output.
Water
Bring connected water data into the same performance picture for clearer visibility and control.
ActiveTrim does not wait for a monthly review to discover that the building has drifted. It keeps responding as conditions change.
Up to 50%
reduction in baseline energy consumption
Through automated, adaptive energy management across suitable connected systems.
Balances demand and supply automatically
Coordinates equipment and energy use so resources are delivered when and where they are actually needed.
Subtly nudges the building towards peak efficiency
Makes thousands of small adjustments that steadily improve overall performance, every minute of the day.
Replaces static rules with dynamic intelligence
Moves beyond fixed BMS rules with adaptive, data-driven optimisation that evolves with the building.
Peak performance comes from continuous attention to thousands of small decisions: when plant starts, how setpoints respond, whether systems overlap and where demand is moving next. ActiveTrim makes those decisions automatically, within the control boundaries agreed for the building.
Optimises schedules and setpoints
Reduces unnecessary plant operation
Coordinates demand and supply
Prevents heating and cooling conflict
Responds to weather and occupancy changes
Maintains comfort while reducing waste
Keeps improvements working after the initial tuning project ends
Autonomous does not have to mean opaque. ActiveTrim works alongside Attain’s analytics, reporting and engineering expertise so teams can see what performance is changing and measure the outcome.
Performance before and after
Compare baselines, trends and results over time.
Clear operating boundaries
Control strategies are configured around the building, its systems and agreed requirements.
Human expertise when it matters
Attain specialists can review performance, investigate exceptions and refine optimisation strategies as the building evolves.
Across Attain deployments, ActiveTrim is designed to deliver rapid energy and operational improvement without disrupting the experience inside the building.
At Old Park Lane Management sites, continuous optimisation contributed to measurable reductions in air-conditioning energy and gas consumption while helping teams maintain more stable conditions and identify hidden operational issues.
