Hotel & Student Accommodation Air Quality Assessment
Specialist air quality assessments for hotels, hostels and Purpose-Built Student Accommodation (PBSA) planning applications. Sensitive-receptor assessment, kitchen odour (EMAQ+) and CHP emissions, by a Chartered Environmentalist.
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 scores the odour risk from the kitchen, including at residential properties above or next to the hotel and the hotel's own bedrooms, and states the level of odour control the extract system needs to provide, for the hotel's kitchen extract specialist to design and install. We can deliver the AQA and the kitchen odour assessment together as one package.
Many hotel and PBSA schemes also include on-site combustion plant, such as gas-fired boilers, CHP units and occasionally biomass, which need to be modelled and stack heights determined. Where mitigation is needed it typically comprises mechanical ventilation drawing from a roof or courtyard intake away from the road, courtyard layout changes, and bedroom orientation away from the most polluted facade. The AQA states what the mitigation needs to achieve; the building services engineer designs and specifies the ventilation system to meet it.
Every hotel and PBSA assessment is carried out and signed off by Malcolm Pounder CEnv MIAQM.

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. Scoring of dispersion, receptor proximity, kitchen size and cooking type, with the hotel's own upper-floor bedrooms included as receptors, and a clear statement of the level of odour control the extract system needs to provide, for your kitchen extract specialist to design and install.
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.
Mitigation Requirements
Where the assessment shows mitigation is needed, the AQA sets out what it must achieve, for example a ventilation intake away from the most polluted facade, so the building services engineer can design and specify the system to meet it. We do not design or specify ventilation systems.
Common Scheme Types
We assess schemes for hotel and PBSA developers, operators and the consultancies advising them. Typical scheme types are listed opposite.
Each assessment is sized to the scheme, from a small boutique hotel to a large PBSA block.
- Central London hotels
- Boutique/aparthotel schemes
- Airport and roadside hotels
- Hostels and budget hotels
- Purpose-Built Student Accom (PBSA)
- University-owned halls of residence
- Mixed-use hotel + residential
- Heritage hotel refurbishments
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 assessment follows the EMAQ+ guidance on controlling odour and noise from commercial kitchen exhaust systems (2018), which scores the odour risk from the kitchen and sets the level of odour control the extract system needs to provide. The design of that system is for the hotel's kitchen extract specialist. We can deliver the AQA and the kitchen odour assessment together as one package.
What mechanical ventilation is required?
Where the assessment shows that air quality at a facade calls for mitigation, a common approach is mechanical ventilation drawing air from a roof or courtyard location away from the road. The AQA states what the mitigation needs to achieve; the building services engineer designs and specifies the ventilation system. Many planning consents secure this through a condition requiring approval of a mitigation scheme.
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 (such as a mitigation strategy).
