ISH China & CIHE 2026 opens next week: 30 years of advancing the HVAC industry and connecting global markets

Technology is playing an increasingly important role in air handling systems.  Air handling systems (AHUs) are essential for heating, ventilation, and air conditioning (HVAC) systems. They condition and circulate air throughout buildings, providing occupants with a comfortable and healthy environment. A typical AHU consists of a fan, filters, coils, and dampers. The fan draws air from the outside or inside the building and circulates it through the other components. The filters remove dust, pollen, and other pollutants from the air. The coils heat or cool the air, depending on the season. The dampers control airflow through the AHU and to different parts of the building. AHUs are used in various commercial, industrial, and residential buildings. They are particularly important in buildings with large numbers of people, such as schools, offices, and hospitals. Technology Innovations in Air Handling Systems In recent years, several technological innovations have been in air handling systems. Some of these innovations include: •  Variable frequency drives (VFDs) : VFDs allow the fan's speed in an AHU to be adjusted, saving energy and reducing noise. •  Energy recovery wheels: Energy recovery wheels transfer heat from exhaust air to supply air, saving energy on heating and cooling. •  Direct expansion (DX) coils: DX coils allow AHUs to heat and cool air without needing a separate chiller or boiler. •  Humidifiers and dehumidifiers: Humidifiers and dehumidifiers can be added to AHUs to control the humidity level in the air, which can improve comfort and health. •  Building automation systems (BAS) : BAS can be used to monitor and control AHUs, which can help to improve energy efficiency and performance. Benefits of Using Technology in Air Handling Systems There are several benefits to using technology in air handling systems, including: •  Energy savings: Technology can help reduce the energy consumption of AHUs, saving building owners money on their utility bills. •  Improved performance: Technology can help to improve the performance of AHUs, such as by providing more precise temperature and humidity control. •  Reduced maintenance: Technology can help to reduce the maintenance requirements of AHUs, which can save building owners money and time. •  Improved occupant comfort and health: Technology can help improve building occupants' comfort and health by providing clean, fresh air. Conclusion Technology is playing an increasingly important role in air handling systems. By using innovative technologies, building owners can improve the energy efficiency, performance, and reliability of their AHUs while also providing a more comfortable and healthy environment for occupants. ...Read more

BIM has transformed construction methods by offering far more integrated, efficient, and collaborative approaches to project management. BIM will continue to evolve in ways that will fundamentally revolutionize construction methods through technological advancements, enhanced interoperability, and sustainable practices—optimizing and increasing project delivery, lowering costs, and improving building performance. The 5D BIM trend significantly improves the traditional 3D Building Information Modeling (BIM) model, which adds cost and scheduling data. This data would help stakeholders understand the financial and time implications of decisions at the design and construction phases, making budgeting, scheduling, and resource allocation very accurate. It also allows for real-time visualization of cost impacts, mitigating risks, and ensuring project continuity. Integrating BIM with AR and VR changes how projects are visualized and stakeholders engage. AR superimposes digital models over physical spaces. It may allow the project manager, architects, or clients to envision a completed building before construction starts. VR will enable walkthroughs, where stakeholders may feel a sense of space amid development. Interactivity bridges the communication gaps common in traditional project settings, encouraging feedback and collaboration. AR and VR in BIM identify design flaws and space discrepancies, reducing costly redesigning and alteration. Cloud-based BIM is an encouraging trend toward industry collaboration that lets stakeholders access the same model in real time, regardless of location. Real-time visibility eliminates many issues and reduces errors based on outdated information. Many people are becoming work-from-home advocates and find the need for such collaboration while working remotely; this increases the dependency of companies on cloud-based BIM solutions. This data-driven approach enables architects and engineers to evaluate design options, minimize energy consumption, reduce waste, and create more friendly-to-the-ecosystem buildings. Some advanced BIM platforms can be integrated with green building certification systems such as LEED, providing metrics and analyses required to meet specific sustainability standards. As environmental concerns continue to define the industry, so will the need for sustainability through BIM. When demand can only continue to increase, construction's speed and efficiency will be more attractive; a focus for companies is now BIM-enabled prefabrication and modular construction. It can eventually allow firms to develop accurate models of the prefabricated modules at the early design and planning stages of BIM uptake, cutting material waste and preventing errors onsite. Reduced disruption on site also results in faster completion times, allowing teams to finish projects within shorter periods while saving labor costs. Artificial intelligence and machine learning are changing the face of Building Information Modeling through predictive analytics and data-driven decision-making. By analyzing massive datasets, artificial intelligence can identify hidden patterns and predict potential risks in actual trials, timing project managers to take preventive measures when needed. With the advances in AI algorithms, more integrated BIM will yield more precise planning, better risk management, and efficiency and resilience for the construction industry. ...Read more
