Advanced Solutions for Commercial Buildings

Enhancing HVAC and refrigeration efficiency is critical for commercial buildings, where air conditioning is a major energy consumer. Efficient systems reduce energy use, operating costs, and equipment wear, while passive cooling and condensation control lower heat gain, prevent mould growth, and improve indoor comfort, durability, and occupant health.

Energy Loss in Commercial Buildings

Energy inefficiency in commercial buildings rarely stems from a single issue. It typically develops across HVAC systems, building envelopes, airflow stability, and moisture control — causing chillers and AHUs to work harder than necessary.

Common sources of energy loss include:

• HVAC performance decline — internal thermal resistance, coil inefficiency, unstable Delta-T
• Building heat gain — solar radiation through façades, roofing heat absorption, poor insulation
• Airflow imbalance — uneven cooling distribution and excessive cycling
• Condensation & moisture — added latent load and insulation degradation

These inefficiencies are interconnected: heat gain increases cooling demand, which amplifies system losses and energy consumption.

A systems-level engineering approach is required to restore performance and reduce operating costs sustainably.

HVAC Energy Effiency Enhancement

Radiant Climate Technologies improves HVAC energy efficiency by restoring condenser and cooling coils, then enhancing heat transfer with [1]Radiant+ E3 Coating heat-conductive coating. [2] MaxR100® is added to the refrigerant loop to remove oil fouling, reduce friction, lower compressor load, and further improve refrigeration cycle efficiency.

In Chiller-AHU System, water is used as a medium of heat transfer for transfering the cooling effect from chiller the AHU, which cools the air to be supplied to the buildings. Water has limited heat transfer capacity due to its high specific heat capacity and heat conductivity. [3] Aquene Heat Transfer Fluid is used as an alternative that enhances the heat transfer capability between the chiller and AHU. 

The chiller plant and connected air-conditioning systems that are controlled by fixed schedules, manual setpoints, or conservative buffer settings, are likely overcooling and wasting energy. 

Our [4] AI-driven HVAC Optimization System adds an intelligent optimisation layer that learns your building’s actual cooling patterns and continuously adjusts chilled-water production to match real demand. Designed for retrofit integration, it works wirelessly with existing BMS/BA systems — upgrading performance without replacing your current automation infrastructure.

Passive Cooling, Comfort and Hygiene of Buildings

Radiant Climate Technologies delivers passive building cooling by applying PentaGard on exterior walls to reflect solar heat and reduce heat transfer. Axion25 is applied to interior walls to provide thermal insulation, suppress condensation, inhibit mold and bacteria growth, and ensure long-term surface stability without chemical leaching. Noise insulation is also expected. Ceralite^TM , the high-transparency heat and UV control window film, is applied on the glass windows to reduce solar heat gain while preserving near-original glass appearance.  

Heat and UV Control Window Film

Using Ceralite™, a high-transparency heat and UV control window film, the film rejects heat without blocking daylight, maintains low reflectivity and natural color and preserves architectural and brand intent.
