These versatile systems are a good option for smaller commercial buildings, and offer a substantial reduction in carbon emissions compared to traditional heating and cooling systems.
Proper Air Balancing
Proper air balancing is a crucial practice when optimising HVAC systems for sustainability. Carried out by professional HVAC technicians, this process involves adjusting dampers, fans and other components to achieve an even distribution of conditioned air throughout a building, preventing temperature variations and hot or cold spots.
This results in reduced energy consumption, lowering operational costs and contributing to more sustainable operation.
Air balancing is the last stage of the initial installation process, but it’s also recommended whenever there are changes to the building layout, occupancy patterns, or modifications to the HVAC system itself. Additionally, it should be performed periodically as part of routine maintenance, ensuring that the system continues to operate at peak efficiency.
Energy Recovery Systems
Mechanical ventilation with heat recovery (MVHR) is a versatile technology that provides both ventilation and energy efficient temperature control.
These systems are designed to recover and reuse heat from exhaust air to preheat incoming fresh air, significantly reducing the reliance on additional heating. For example, if certain areas of a commercial building generate excessive heat - like kitchens or server rooms - MVHR systems can capture and redistribute this thermal energy to other zones in need.
By capturing and recycling energy that would otherwise be wasted, MVHR systems enhance energy efficiency and reduce the carbon footprint of HVAC systems.
Advanced Building Automation Systems
Advanced Building Automation Systems (BAS) optimise the performance of HVAC equipment based on real-time conditions.
They work by collecting data from sensors distributed throughout the building, which monitor conditions such as temperature, humidity, occupancy, and outdoor weather. This real-time data is processed by the BAS controllers, which then adjust HVAC operation accordingly. For example, if a particular zone is unoccupied, the BAS may adjust the temperature or reduce ventilation rates to conserve energy.
These systems are expensive to instal, making them impractical for smaller commercial buildings. However, thanks to advancements in technology there are now more affordable and scalable Intelligent Building Management Systems (IBMS) available.
These offer a more practical solution for smaller businesses looking to automate energy efficiency and improve the sustainability of their HVAC systems.
