Energy Efficiency Retrofit
System Upgrades for Energy Efficiency & CO₂ Reduction
We provide tailored retrofit solutions to improve the energy performance of existing buildings for individual systems such as air handling units (AHUs), control systems, heating systems, chiller plants, fans, pumps, compressed air systems, and lighting installations are assessed for potential replacement — either due to aging or because upgrading them offers significant benefits in terms of energy efficiency and CO₂ reduction.
Air Handling Units (AHU)
High-Performance Ventilation with Optimized Control Strategies
Upgrading air handling units with high-efficiency EC or VSD fans, optimized control strategies, and improved heat recovery systems can reduce energy use by up to 50 %. Intelligent demand-based control adapts ventilation rates to occupancy and climate conditions, while continuous monitoring ensures sustained performance and indoor air quality.
Chiller Systems
Maximum Cooling Performance with Minimum Energy Use
Modern high-efficiency chillers with variable-speed compressors and optimized part-load performance can reduce cooling energy consumption by up to 40 %. Advanced control strategies adapt chiller operation to real-time demand, while improved heat exchangers and refrigerants enhance system efficiency. Continuous monitoring ensures reliable operation and long-term savings.
Ventilation Systems
Energy-Saving Airflow with Optimized Control
Replacing outdated fans with high-efficiency EC or VSD models and upgrading ductwork design can cut energy use while improving airflow and comfort. Demand-controlled ventilation adjusts air supply to occupancy and air quality, avoiding unnecessary operation. Integrated monitoring and smart controls ensure sustained performance and reduced operating costs.
Heating Generation
Optimized Boiler Plants, Heating Stations, and District Heating Stations
Upgrading to high-efficiency boilers, condensing technology, and optimized heat exchanger systems can significantly reduce fuel consumption and emissions. Advanced control strategies match heat output precisely to demand, minimizing standby losses. Integration of renewable heat sources and continuous performance monitoring ensures reliable operation and long-term cost savings.
Pump and Hydraulic Systems
Optimized Flow for Energy Savings and System Reliability
Replacing constant-speed pumps with high-efficiency variable-speed models and optimizing hydraulic circuits can cut energy consumption by up to 50 %. Correct pump sizing, improved piping design, and intelligent control strategies ensure demand-driven operation. Continuous monitoring and balancing maintain optimal performance, reduce wear, and extend equipment lifetime.
Control Systems & BMS
Intelligent Control for Optimized Energy Performance
Upgrading to advanced control systems and integrated building management platforms enables real-time monitoring, demand-based operation, and predictive maintenance. Optimized control algorithms coordinate HVAC, lighting, and other systems for maximum efficiency. Data analytics identify improvement opportunities, while automated reporting supports compliance with energy and sustainability targets.
