Air Quality Assessment for Schools & Education Developments
Specialist air quality consultancy for new schools, nurseries and education facilities — protecting the most sensitive receptors with rigorous, council-accepted assessments by chartered environmentalists.
Protecting Children From Air Pollution Through Better Planning
Schools, nurseries and other education uses occupy a unique position in the air quality planning system: they house the most sensitive receptors. Children's lungs are still developing, they breathe a greater volume of air per unit body weight than adults, and they spend long, predictable periods at the same location. The result is that IAQM/EPUK guidance, most Local Plans and the WHO 2021 air quality guidelines all apply more stringent criteria to schools than to general residential or commercial development.
Malcolm Pounder CEnv MIAQM leads our education-sector work personally. We model annual mean and short-term NO2, PM10 and PM2.5 concentrations at the proposed school facade, in outdoor play and amenity areas, and at any nearby existing schools that may be affected by changes in traffic. Modelling is carried out with ADMS-Roads and calibrated against local LAQM monitoring where available, with results compared against the UK air quality objectives (40 µg/m³ NO2 annual mean) and, increasingly, against WHO 2021 guidelines as a long-term target.
Where a new school must be built near a busy road or within an AQMA, the assessment will go further than just concentration figures. We work through the full mitigation hierarchy: location, layout and orientation, mechanical ventilation with appropriate filtration (CIBSE TM40 / F7+), idle-zone management at drop-off and pick-up, and School Travel Plan integration. We co-ordinate closely with M&E engineers on intake locations and filter specification so the air the children actually breathe inside the building is genuinely good.
We work for local authority capital projects teams, MAT (multi-academy trust) estates departments, planning consultants delivering new free schools and SEN provision, and architects designing nurseries and early-years settings. Whether you are at site-search stage or responding to a planning officer's request for further information, we can deliver assessment work that is technically rigorous and child-focused.
Our School & Education AQA Services
From site feasibility through to planning submission and condition discharge — air quality work that is genuinely child-focused.
Sensitive-Receptor Exposure Modelling
ADMS-Roads modelling of annual mean and hourly NO2, PM10 and PM2.5 at proposed classroom facades and outdoor play and amenity areas. Results compared against UK Air Quality Strategy objectives and, where relevant, WHO 2021 guidelines as a long-term target.
Ventilation Specification (TM40)
Filtration and intake-location recommendations co-ordinated with M&E engineers to CIBSE TM40 / F7+ standards. Pollutant concentration mapping at proposed intake locations and recommendations for active management of intake closure during high-pollution episodes.
Traffic & Travel Plan AQ Inputs
Air quality input to School Travel Plans and Transport Statements, including idle-zone analysis at drop-off and pick-up, predicted change in local NO2 from school-related traffic, and air-quality justification for active travel and anti-idling measures.
Planning Reports & Condition Discharge
Full planning-submission air quality reports written for environmental health teams and statutory consultees, including AQMA exposure analysis where relevant. Post-consent we support discharge of air quality and ventilation-related planning conditions through to handover.
Who Commissions a School AQA?
We work for local authority capital programmes, multi-academy trust estates teams, planning consultants delivering new free schools or SEN provision, and architects designing nurseries and early-years settings. Most new education-sector developments will need air quality input at planning stage and, increasingly, ongoing input into ventilation and travel plan strategies.
We are also commissioned to provide air quality evidence for existing school estates — for example to support cases for traffic calming, school streets or air quality interventions.

Frequently Asked Questions
Why are schools treated as the most sensitive receptors in air quality terms?
Children's lungs are still developing, they breathe a greater volume of air per unit body weight than adults, and they spend long, predictable periods at the same location (the school). Chronic exposure to elevated NO2 and particulate matter is now well-established as harmful to lung development, cognitive performance and long-term cardiovascular health. As a result, IAQM/EPUK guidance and most local planning authorities apply more stringent criteria to schools, nurseries and other education uses than to general residential development.
What is the air quality threshold for new schools near busy roads?
The headline UK air quality objective for annual mean NO2 is 40 µg/m³, and this applies at the facade of any new school building. In practice, many LPAs and statutory consultees expect compliance to be demonstrated more conservatively for schools — often with reference to the WHO 2021 guideline of 10 µg/m³ as a long-term target and with explicit attention to outdoor play areas, drop-off zones and ventilation intakes. We model facade and external amenity concentrations using ADMS-Roads and present results clearly against both UK and WHO criteria.
Does air quality affect school planning applications?
Yes — increasingly so. NPPF paragraph 192 and Local Plan policies across the UK require that new developments do not cause unacceptable air quality impacts and, equally importantly, that they are not located where occupants will be exposed to unacceptable concentrations. A new school on a busy A-road with elevated NO2 will face scrutiny from the LPA's environmental health team and may require detailed assessment, mechanical ventilation with filtration, and modifications to layout or orientation before planning permission is granted.
What mitigation can be used for new schools in air quality terms?
The hierarchy is location first, then layout, then ventilation. Where a school must be built near a busy road, mitigation typically combines: setbacks of classrooms and play areas from the kerb; orientation so the most sensitive rooms face away from the road; mechanical ventilation with at least F7-rated filtration (CIBSE TM40) and intakes at roof level away from the pollutant source; planting and physical barriers (with realistic, evidence-based expectations of the effect); a robust School Travel Plan; and active management of idling vehicles at drop-off and pick-up times.
How much does an air quality assessment for a school cost?
Fees depend on the proximity to busy roads, whether existing AQMAs are involved, the level of detail required by the LPA, and whether ventilation specification is in scope. A simple screening assessment for a rural primary school is at the lower end; a detailed ADMS-Roads modelling assessment for a new secondary school on a London A-road, with full ventilation specification, sits higher. We provide fixed-fee quotes after a short scoping conversation.
