Smart Demand Side Management: Reducing Overcooling in Buildings with IoT Sensors and EMS Solutions by KCK Sustainability Solutions

In today’s energy-conscious world, building owners and facility managers face a common challenge: overcooling. Spaces like corridors, hallways, storerooms, and other low-occupancy areas often receive the same cooling levels as heavily used zones, resulting in wasted energy, unnecessary operational costs, and reduced HVAC efficiency.

At KCK Sustainability Solutions Sdn Bhd, we help clients take control of their demand side energy usage through intelligent technologies like IoT sensors and advanced Energy Management Systems (EMS), ensuring chilled water plants and HVAC systems operate only when and where cooling is needed.

The Hidden Cost of Overcooling

Overcooling is not just an energy efficiency issue—it’s a financial drain. In many commercial and industrial facilities, central chilled water plants run continuously at settings designed for full occupancy, regardless of the actual building usage. Corridors, hallways, and meeting rooms often remain overcooled even when unoccupied, leading to:

• Higher electricity bills

• Increased wear and tear on chillers, pumps, and air handling units

• Reduced equipment lifespan

• Negative environmental impact due to excessive energy consumption

How Demand Side Management Makes a Difference

Demand Side Management (DSM) is the strategic adjustment of energy use patterns to match actual demand. Rather than letting HVAC systems run at a fixed output, DSM allows you to dynamically reduce cooling in underutilised zones—without affecting comfort in occupied areas.

With DSM, energy consumption is optimised, operating costs are reduced, and HVAC equipment works more efficiently, prolonging its life.

IoT Sensors: Real-Time Cooling Control

At KCK, we integrate IoT-based temperature, humidity, and occupancy sensors into your building’s control system. These smart devices continuously monitor environmental and occupancy conditions in each area, providing real-time data to your EMS (Energy Management System).

For example:

• Corridors and hallways: Sensors detect low or zero occupancy and reduce cooling output automatically.

• Meeting rooms: Cooling ramps up only when the space is in use.

• Storage areas: Temperatures are kept at safe but energy-efficient levels.

By targeting overcooling at the demand side, you avoid unnecessary chiller loads, reduce electricity usage, and save significantly on operational costs.

EMS: Smarter Chiller and HVAC Control

Our Energy Management System integrates IoT sensor data to automatically adjust chiller sequencing, chilled water supply temperatures, and air handling unit output based on actual building needs. This intelligent control ensures:

• Chillers operate only when necessary

• Cooling levels match occupancy patterns

• Reduced peak demand and lower utility bills

• Improved overall building sustainability performance
