    The zero effect

    In a net zero world, it doesn’t matter whether we divide emissions by headcount or square meterage. By any measure, the balance of emissions must be the same. Zero.

    Computational fluid dynamics modelling of ventilation in road tunnels: enhancing air quality and safety

    Ventilation units within vehicle tunnels play a pivotal role in ensuring safety and optimal air quality for occupants. These units are used to assist with propelling air from one end to the opposite end of the tunnel. Computational fluid dynamics (CFD) has emerged as an invaluable design tool for engineers and stakeholders, offering simulated insights and data to optimise safety and efficiency in tunnel projects. This paper emphasises the advantages of CFD for road tunnel ventilation design, showcases a case study involving impulse fans, and highlights the positive effects on project costs and overall tunnel ventilation performance.

    CFD Analysis of Fixture Output Impact on Upper Room Germicidal Ultraviolet Light System Performance

    Ultraviolet germicidal irradiation (UVGI) using electromagnetic radiation in the UV‑C wavelength band of 200–280nm can prevent the reproduction of microorganisms. Several factors related to UV fixtures, HVAC layout and the resulting airflow flow patterns can affect the performance of upper‑room UVGI applications.
