  • The Challenge

    Our client required detailed air dispersion modelling for the assessment of air quality impacts associated with proposals for a disaster recovery scheme at the hospital.

  • Our Approach

    Our team of air quality experts:

    • Conducted a detailed modelling assessment for the operation of a new disaster recovery scheme to provide a backup supply of steam in the event of critical failure.
    • Incorporated embedded mitigation within the model by strategically locating boilers and increasing flue stack heights to minimise impacts on local air quality.
    • Examined the adjacent Portsdown Hill Nature Reserve Site of Special Scientific Interest (SSSI) and demonstrated that NO2 concentrations from the new disaster recovery scheme were permissible.
  • The Outcome

    The results of this assessment showed that air quality did not present a constraint to the operation of the disaster recovery scheme.
