Service Overview
Turn fragmented energy data into practical actions for lower consumption, stronger operational visibility and measurable sustainability performance.
Desapex delivers digital-first energy management services for buildings, facilities, industrial assets and data centres. We connect engineering knowledge with energy audits, smart metering, building energy modelling, performance analytics and digital-twin-enabled workflows to help teams understand how energy is used, where performance is being lost and which improvements should be prioritised.
From design-stage simulation to operational monitoring, our approach creates a structured path from data capture to informed action without separating energy performance from the systems, assets and maintenance processes that influence it.

What is energy management?
Energy management is the continuous process of measuring, analysing and improving how a building or asset uses energy. It combines metering, audits, engineering analysis, energy models and performance dashboards to identify inefficiencies, prioritise energy conservation measures and track results over time. When connected with BMS, IBMS or digital twin platforms, it also supports better operational and maintenance decisions.
Our Digital-First Approach
Establish the performance baseline
We begin by defining the asset, systems, operating conditions and available utility data. Depending on the project, this may include a carbon and energy audit, review of bills and tariffs, equipment inventories, operating schedules, BMS data and existing drawings or BIM information.
Capture and connect energy data
Desapex develops the information architecture for energy monitoring, including smart metering and submetering strategies, utility data structures and connections with BMS, IBMS, DCIM, CMMS or EAM platforms where appropriate.
Model and analyse performance
We use building energy modelling and simulation to evaluate loads, systems and operating scenarios. Our engineering workflows can include whole-building energy simulation, HVAC and cooling analysis, lighting analysis, energy conservation measure identification, PUE and WUE studies for data centres, and assessment of operational cost, carbon and net-zero pathways.
Prioritise improvement measures
Potential measures are compared against operational needs, implementation complexity and expected performance impact. Recommendations may address controls, schedules, setpoints, equipment selection, cooling and airflow, lighting, water-energy interactions, renewable energy integration or maintenance practices.
Monitor, verify and improve
Dashboards and performance analytics help teams track consumption, cooling efficiency, water and carbon indicators, system behaviour and exceptions over time. Digital twin and asset-information workflows can connect energy performance with equipment data, maintenance schedules and issue-resolution processes.
Core Deliverables
The scope is configured around the asset, data maturity and business objective. Typical deliverables include:
Energy-use baseline and consumption profile
Carbon and energy audit findings
Utility, smart-metering and submetering strategy
Building energy model or energy simulation report
HVAC, cooling, airflow or lighting performance analysis
Energy conservation measure register with prioritisation
BMS, IBMS, DCIM, CMMS or EAM integration requirements
Energy, water and carbon performance dashboard framework
PUE and WUE optimization studies for data centres, where applicable
Renewable energy and storage integration studies
Net-zero energy pathway and phased optimization roadmap
Measurement, monitoring and performance-review plan
Post-occupancy optimization recommendations, where included in scope
Why Choose Desapex
Engineering and digital delivery in one workflow
Energy performance is shaped by mechanical, electrical, controls, architectural and operational decisions. Desapex brings these disciplines together through coordinated BIM and digital engineering workflows, helping recommendations remain technically connected to the asset.
From simulation to operations
Our capabilities span design-stage energy modelling, smart-building and IBMS design, commissioning support, operational dashboards, digital twins and asset information management. This creates continuity from predicted performance to monitored performance.
Connected asset intelligence
We can structure energy information alongside asset data and connect it with BMS, DCIM, CMMS or EAM environments. This helps operational teams relate abnormal consumption to systems, equipment and maintenance activity.
Suitable for complex and mission-critical facilities
Desapex materials demonstrate energy, cooling and performance workflows for buildings, industrial environments and data centres, including energy analytics, PUE/WUE optimization, CFD, lifecycle assessment and renewable energy studies.
Standards-aware, decision-focused delivery
Our broader digital engineering practice is built around structured information management and internationally recognised engineering and sustainability frameworks. The goal is not simply to produce another report, but to create information that teams can use, govern and review
Unique Selling Proposition
Desapex connects energy engineering with the digital systems that operate the asset.
Instead of treating an energy audit, building energy model, smart-building platform and digital twin as separate initiatives, we build a connected workflow: establish the baseline, integrate trusted data, simulate performance, prioritise improvements and track outcomes. This combination of multidisciplinary engineering, BIM, smart metering, system integration and asset intelligence gives owners a practical foundation for continuous energy optimization and long-term decarbonization.
