4i4 adds an optimization layer on top of your existing ‘Central Tilstandskontrol og Styrings’ System (CTS) or also called ‘Building Management System’ (BMS). Using the data you already have, we continuously improve heating, ventilation and cooling (HVAC) performance, reducing energy use while keeping comfort and operational limits stable. 

Your CTS/BMS keeps systems safe and within fixed rules. But buildings behave dynamically since weather, occupancy, and loads change all the time. 4i4 helps systems adapt to real demand by optimizing setpoints and interactions over time without changing your safety boundaries.

Typical outcomes include: 

• Lower energy consumption and cost 

• More stable operation with fewer alarms and complaints 

• Less manual tuning for facility teams 

• Clear documentation of performance and savings 

No and that’s intentional. Many facility managers already tune schedules and setpoints. The problem is time and complexity with too many parameters and too many changing conditions. 4i4 does the repetitive monitoring and analysis continuously and turns it into concrete actions for the facility managers.

For most portfolio-type cases, the target is payback within a few years. We measure and document effects continuously, so the business case is based on real results, not assumptions.

Our software connects to your CTS via BACnet and collects real-time data from your HVAC systems and relevant sources (e.g. weather, schedules, energy meters). We then build a digital twin of your HVAC setup and how your building behaves. The result is a continuous optimization loop that:  

• Detects inefficiencies and deviations from optimal operation 

• Predicts demand based on weather, schedules, and building response 

• Adjusts setpoints dynamically to minimize energy use while maintaining comfort 

• Monitors performance and documents savings and ESG impact 

We’re designed to work with what’s already available. If data is limited or the systems are old, the software learns from live operation and improves over time. If a key sensor or component is missing for reliable optimization, we’ll flag it and quantify the value of upgrading it. 

• Facility/operations teams: we provide 24/7 monitoring, anomaly detection and clear guidance to reduce blind spots and routine manual work.   

• Management/asset owners: continuous evidence of savings and performance improvements, supporting sustainability and management with reports for ESG.  

We usually begin with a pilot on one or a few representative sites. We establish a baseline, run optimization transparently, review results together, and then scale if the value is clear.

4i4 uses data from your CTS/BMS and stores and handles it according to your IT and security requirements. The solution can be deployed in a way that fits your infrastructure and IT governance model.
