Consulting & Programs
ICTnexus offers a comprehensive suite of energy management solutions tailored to meet diverse client needs:
- Basic Program: Focuses on essential energy monitoring and management, with an optional Building Management System (BMS) retrofit to modernise existing infrastructure.
- Plus Program: Enhances the basic offering with advanced monitoring and targeting capabilities, coupled with sophisticated energy management and analytics tools for deeper insights and optimization.
- Enterprise Program: Outsourced Energy and Facility Management. Provides comprehensive outsourced services including monitoring, targeting, and Measurement and Verification (M&V) following the International Performance Measurement and Verification Protocol (IPMVP)

Concept Phase
Define Scope and Boundaries: Clearly outline the physical or organisational limits of the energy management system.
- Conduct Energy Review: Analyse energy use and consumption based on measurements and data to identify Significant Energy Uses (SEUs)
- Establish Energy Baseline (EnB): Use information from the energy review. Consider a suitable time period, typically before implementing energy improvements. Ensure the baseline reflects a specified period
- Identify Relevant Variables: Determine factors that significantly affect energy performance, such as occupancy or weather conditions
- Normalise Data: Adjust the baseline and Energy Performance Indicators (EnPIs) to account for these variables, allowing for meaningful comparisons over time

The Cycle
The energy management cycle is a systematic approach to continuously improve an organization's energy performance. Here's how to establish it:
- Engage Management and secure top-level commitment to energy management
- Develop and communicate a clear energy policy
- Allocate resources and define roles and responsibilities
- Set clear, measurable energy performance goals with target dates
- Identify and prioritize energy conservation measures (ECMs) and execute them
- Evaluate the effectiveness of the energy management efforts
- Identify new opportunities for improvement

Operational Phase!
To prevent the return to old behaviors and analyse savings in an ongoing IPMVP-like process with AI, we will implement the following strategies:
- Continuous Monitoring and Analysis: Real-time data collection, AI-powered analytics and automated alerts to flag anomalies
- Behavioral Reinforcement: Regular training, visualisation tools
- Gamification: Implement friendly competition or reward systems to encourage sustained energy-efficient practices
- Savings Analysis and Verification: We use AI-enhanced savings calculations by accounting for complex interactions and patterns
- Continuous Improvement: Regular reviews and keep the Cycle going
