Overview

Old Park Lane Management (OPLM) implemented Hilson Moran’s Attain platform to optimise energy performance and provide fault detection diagnostics across two London office buildings: LSQ 30 Panton Street and 4 Millbank.

The deployment focused on improving operational efficiency, reducing energy waste, and providing clearer visibility into building performance through continuous monitoring and analytics.

The Challenge

Both buildings faced difficulties maintaining efficient operations across complex building systems. The sites included a mix of legacy infrastructure and newer systems, creating operational inconsistencies and inefficiencies.

Several key issues were identified:

These challenges made it difficult to maintain stable building performance or track sustainability progress.

The Solution

Attain was deployed across both sites to connect to operational building systems and enable continuous monitoring, optimisation, and diagnostics.

The platform integrated with systems including:

Attain introduced two key capabilities:

Alongside Attain, the Canopy platform was used for data visualisation, enabling OPLM to monitor energy consumption and track improvements over time.

Implementation

The rollout followed a structured three-phase deployment process.

Phase 1 — Site Connection and Onboarding

Building Operational System data was connected to the platform, allowing Attain to ingest and process operational data from both sites.

Phase 2 — Performance Monitoring

Energy and system performance data were visualised and analysed against performance benchmarks to establish a baseline and identify inefficiencies.

Phase 3 — ActiveTrim and Fault Diagnostics

Automated optimisation and FDD capabilities were deployed. Site teams worked with the system insights to address faults and improve system performance.

Outcomes

Over an eight-month period, the deployment produced measurable performance improvements.

Energy reductions

• 8% reduction in air-conditioning energy use

• 22% reduction in gas consumption

Carbon impact

Equivalent to approximately 179 tonnes of CO₂!

Operational improvements

• Air-conditioning communication outages were identified and resolved

• Fault and error codes from operational systems were surfaced and addressed

• Temperature conditions across buildings became more stable throughout the year

Visibility and monitoring

• Building energy performance could now be continuously tracked

• Issues could be identified and addressed earlier

Financial impact

• Energy reductions translated into measurable cost savings, helping deliver return on investment.

Key Learnings

The project demonstrated how intelligent optimisation platforms like Attain can unlock significant performance improvements even in complex, legacy-heavy buildings.

Designed to work with existing infrastructure

Older building systems often present integration challenges, but Attain’s flexible architecture enables it to connect with a wide range of operational technologies, making optimisation possible without major system overhauls.

Data builds confidence in automation

By providing clear performance insights and transparent reporting, Attain helped operational teams better understand how their buildings behave, gradually increasing trust in automated optimisation.

Continuous optimisation delivers lasting impact

Rather than relying on periodic manual adjustments, Attain continuously monitors and tunes building performance. This ensures energy efficiency improvements are sustained over time rather than achieved only during short-term optimisation efforts.

Actionable insights accelerate operational improvements

With automated fault detection and real-time diagnostics, building teams were able to quickly identify and address issues that might otherwise go unnoticed, improving both efficiency and comfort.
