Hotel & Student Accommodation Air Quality Assessment
Specialist air quality consultants for hotels, hostels and Purpose-Built Student Accommodation (PBSA) planning applications. Sensitive-receptor assessment, mechanical ventilation specification, kitchen odour (EMAQ+) and CHP emissions — by chartered environmentalists.
Why Sleeping Accommodation Needs Particular Care
Hotels, hostels and Purpose-Built Student Accommodation (PBSA) are classified as sensitive receptors under the IAQM/EPUK 2017 guidance because residents and guests sleep there overnight. That triggers the full set of UK Air Quality Objectives at the building, in particular the 40 µg/m³ NO2 annual mean and the PM10 and PM2.5 objectives. For schemes located within an AQMA, beside a busy A-road or in central London, this is rarely a "screening only" exercise — detailed dispersion modelling and a clear mitigation strategy are normally required.
Hotels frequently include on-site catering (breakfast kitchens, restaurants, banqueting), which adds a second layer to the assessment: a kitchen extract odour study to the EMAQ+ 2018 guidance Control of Odour and Noise from Commercial Kitchen Exhaust Systems. This classifies the cuisine and cooking style, specifies grease and odour filtration, and sets stack height and direction relative to nearby sensitive receptors (including residential properties above or adjacent to the hotel itself). We routinely deliver combined AQA + kitchen odour packages.
Many hotel and PBSA schemes also include on-site combustion plant — gas-fired boilers, CHP units, and occasionally biomass — which need to be modelled and stack heights determined. Mitigation typically comprises mechanical ventilation with NO2-rated filtration drawing from a roof or courtyard intake away from the road, courtyard layout optimisation, and bedroom orientation away from the highest-pollution facade. We work directly with the building services engineer to ensure the AQA mitigation translates faithfully into the M&E specification.

End-to-end air quality support from pre-application through to mitigation condition discharge.
Planning AQA
Full operational-phase Air Quality Assessment, sized to the scheme: screening for small hotels in clean-air areas, ADMS-Roads detailed modelling for larger schemes or those in/near AQMAs. NO2, PM10 and PM2.5 assessed at every facade and balcony, with IAQM 2017 significance evaluation and mitigation appraisal.
Kitchen Odour Assessment (EMAQ+)
EMAQ+ 2018 kitchen extract odour assessment for hotel restaurants and breakfast kitchens. Cuisine classification, filtration specification (grease, particulate, carbon, UV/ozone), stack height and discharge direction, and demonstration of acceptable conditions at the nearest sensitive receptors — including the hotel's own upper-floor bedrooms.
CHP & Boiler Emissions
For schemes with on-site CHP, gas-fired boilers or (occasionally) biomass plant, we model the stack emissions of NOx and PM, calculate stack height to Defra D1, and demonstrate compliance with relevant ELVs and AQAL/EAL benchmarks. Integrated within the main AQA so the LPA sees a single coherent document.
Mechanical Ventilation Specification
Where mitigation is needed, we specify the filtration class (typically EN ISO 16890 ePM1 ≥ 50% for NO2/PM2.5 reduction), intake location, ducting routing and bypass arrangements. We coordinate with the building services engineer so the AQA mitigation flows seamlessly into the M&E design and ultimately the as-built ventilation system.
Common Scheme Types
We work with hotel developers and operators, PBSA developers, university estates teams, hostel chains and the consultancies advising them. Most of our work in this sector falls into the categories opposite.
From boutique hotels in central London to 600-bed PBSA towers in major university cities, we have the depth to deliver to programme.

Frequently Asked Questions
Do hotels need an air quality assessment?
Yes, most do. Hotel rooms are classified as sensitive receptors under IAQM/EPUK 2017 because guests sleep there overnight, and many hotel schemes also include kitchens (with extract odour), CHP/biomass plant rooms, and significant trip generation. For schemes in or near an AQMA, in central London, or for new hotels with on-site combustion plant, an air quality assessment is normally required at planning. For very small hotels in low-pollution areas a brief screening assessment may suffice.
Is PBSA treated the same as residential accommodation?
For air quality purposes, yes. Purpose-Built Student Accommodation (PBSA) is treated as residential under IAQM/EPUK 2017 because residents sleep there and are present for long periods. The same 40 µg/m³ NO2 annual mean objective applies, the same dwelling-count thresholds are used in screening, and the same sensitive-receptor approach is taken in detailed assessment. PBSA also raises particular issues around courtyard layouts, ventilation through external walls onto busy roads, and on-site catering.
What about hotel kitchen odour?
Hotel restaurants and breakfast kitchens often need a kitchen extract odour assessment alongside the AQA. The standard approach follows the EMAQ+ 2018 guidance "Control of Odour and Noise from Commercial Kitchen Exhaust Systems", which classifies cuisine and cooking style, sets minimum filtration (grease, particulate, carbon and where needed UV/ozone) and specifies stack height and direction relative to nearby sensitive receptors. For larger hotels we routinely deliver a combined AQA + kitchen odour assessment as a single integrated package.
What mechanical ventilation is required?
For schemes near busy roads or in AQMAs, the standard mitigation is mechanical ventilation with NO2-rated filtration (typically EN ISO 16890 ePM1 ≥ 50% or equivalent) drawing air from a roof or courtyard location away from the road. We specify the filtration class, intake location and bypass arrangements in the AQA, then liaise with the building services engineer to ensure these are carried through into the M&E design and ultimately into the as-built scheme. Many planning consents condition this through a "mitigation scheme" approval.
What does a hotel or PBSA AQA cost?
Fees depend on the scale of the scheme, location (in/out of AQMA), inclusion of a kitchen odour assessment, and whether detailed dispersion modelling is required for traffic or CHP/biomass plant. For a typical 100-bed hotel or 300-bed PBSA in a London borough or major UK city, we provide a fixed-fee quote covering the planning AQA, kitchen odour assessment (if needed) and any associated documents (mitigation strategy, ventilation specification).
