HVAC INTEGRATION IN BUILDING MANAGEMENT SYSTEMS ( BMS ) The market trend leans toward BMS solutions that streamline operations , reduce energy consumption , and cut costs . HVAC systems , being major energy consumers , are central to achieving these goals . The rise of smart buildings and the proliferation of internet-connected devices drive the adoption of advanced HVAC technology .
These systems go beyond standalone heating , ventilation , and air conditioning ( HVAC ) units . Integration with lighting , security , and other BMS components optimises energy usage and enhances overall building performance .
HVAC systems maintain indoor comfort by controlling temperature , humidity , and air quality .
BMS platforms leverage HVAC data to ensure optimal conditions for occupants . Sensors monitor parameters like carbon dioxide levels , toxicity , and refrigerant status . The global phase-out of R22 refrigerant ( due to its ozone-depleting properties ) accelerates the demand for energy-efficient HVAC systems . BMS integration ensures compliance with regulations while improving overall building sustainability .
The below is actually Ryan Rennie ’ s regular contribution , so please put his usual photo with it .
ENHANCING BUILDING COOLING EFFICIENCY Within Schneider Electric ’ s product lines , Elliwell is a brand within the refrigeration space , distributed by Keystar , though the company ’ s controls offerings extend beyond that . By
Fine-tuning and managing BMS alarms can be cumbersome and time-consuming for facility managers .

The HVAC sensors market is witnessing significant growth , fuelled by increasing energy consumption .
offering seamless integration , versatility , and advanced features , Schneider Electric aims to drive efficiency and sustainability in the building and data centre operations landscape .
Thabang Buys , buildings segment leader at Schneider Electric notes that while Elliwell is owned by Schneider Electric , there is a distinct separation in terms of how products are made available . This distinction allows for greater flexibility in distribution and purchasing channels .
“ EcoStruxure Building Operation ( EBO ) is the primary platform in Schneider Electric ’ s portfolio . It serves as a comprehensive HVAC control solution , leveraging a mesh platform to optimise building operations . Its various components include field devices ( sensors ), programmable logic controller ( PLC ) controls , and integration with security offerings . It has evolved over the years through acquisitions and strategic integrations ,” he notes .
While EBO is commonly associated with building environments , it is equally versatile in data centre applications . Buys cites examples of AWS data centres in Cape Town utilising EcoStruxure for efficient operations .
“ Field devices , including sensors for valves and actuators , temperature , humidity , CO2 levels , and pressure , form the foundation of the system . These devices are complemented by control mechanisms such as PLCs , ASBs ( analogue signal boards ),
