Air Quality and Daylight, Sunlight and Overshadowing Assessment at Grade II Listed building in Manchester

07.04.16

REC Ltd completed an Air Quality Assessment and Daylight, Sunlight and Overshadowing Assessment in support of the redevelopment of a Grade II listed building in Manchester from educational use to a residential development.

An Air Quality Assessment was required to quantify pollution levels across the proposed development site, consider the site’s suitability for the proposed end use and assess the potential impacts as a result of the proposed development. Dispersion modelling was undertaken in order to predict air quality impacts as a result of road vehicle exhaust emissions associated with traffic generated by the development. The modelling indicated that pollutant levels at the proposed residential units were below the relevant air quality standards and as such, the location was considered suitable for residential use without the inclusion of mitigation measures.

As the proposals included the construction of an additional residential block, there was potential for natural lighting levels at existing buildings to be impacted. Therefore, a Daylight, Sunlight and Overshadowing Assessment was also undertaken. The assessment concluded that the relevant daylight, sunlight and overshadowing criteria were achieved at the majority of receptor locations considered. Where the relevant criterion was not met, the amount of light was still considered acceptable due to the site’s location within an urban environment.

In completion of both assessments and offering specialist advice, impacts on air quality and access to natural lighting were not viewed as a constraint to planning consent and the planning application was submitted to the local authority for consideration.
