Hugh Baird College Air Quality Assessment
REC provided an Air Quality Assessment to support Hugh Baird College’s planning application for a new educational institution in Bootle. The proposals aimed to provide a new college with a capacity of 300 to 350 students to accommodate a growing demand for higher education in the area.
The development site was located adjacent to a major junction in Bootle. As such, an Air Quality Assessment was required by Sefton Council to consider the potential for exposure of college students to elevated pollution levels and the suitability of the proposed ventilation system.
A dispersion modelling assessment was undertaken by REC’s Air Quality Consultants using ADMS-Roads to address the concerns raised by the Local Planning Authority. This involved the prediction of pollutant concentrations across the proposed development site as a result of road vehicle exhaust emissions from the local highway network.
The outcome of the dispersion modelling assessment showed relatively high pollutant concentrations, particularly in the vicinity of the adjacent junction. However, levels at the proposed air inlet locations were below the relevant air quality standard and lower than those on the building façades facing the roadside. As such, the proposed ventilation system was shown to be suitable as it would ensure a supply of clean air for future students.
Air Quality Conclusions
REC’s Air Quality Assessment concluded that air quality issues should not be a constraint to planning consent. This saved the client additional costs associated with the implementation of further mitigation measures or revisions to the building design.
