Modelling
-
ADMS and AERMOD
Our team routinely use the dispersion models ADMS-6 and ADMS-Urban/Roads. Our team also use the USEPA's AERMOD dispersion model which is an alternative to ADMS.
-
CALPUFF
We use Calpuff which is an advanced non-steady-state meteorological and air quality modelling system. Calpuff is a useful tool where terrain or other factors mean the trajectory of the plume will change as it travels.
-
Atmospheric Chemical Transport Models (ACTM)
Our team have experience in the use and development of a number of ACTMs. This includes EMEP/MSC-W (also known as EMEP4UK), CMAQ, LOTOS-EUROS.
-
NWP and OBS Meteorological Data
Our team process and produce meteorological data for future climate predictions and current conditions.

Projects
Sherlock Street
Birmingham
The team undertook the air quality and odour assessment for a large residential-led mixed-use scheme, covering construction and operational impacts. Input to the emerging scheme design was provided throughout the process.
Millharbour
Isle of Dogs, London
The team undertook the air quality assessment and helped Galliard Homes successfully obtain a MCPD and Specified Generator Environmental Permit for the energy centre of a large tower block in central London.
Guinness Brewery, London
Planning
Our team completed the air quality, odour and climate change assessments to support the application for a new Guinness brewery near Covent Garden, London.
105 Victoria Street
Westminster, London
The team were the air quality experts for the planning application to demolish the existing building, extend the existing basement and erect a building of ground, mezzanine, plus up to fourteen-storeys comprising commercial and leisure use.
Broadwater Gardens
Welwyn Garden City
The team prepared the Air Quality ES Chapter for a high-quality development of 289 apartments across several blocks of 4 and 9 storeys in height. Support was provided for both the construction and operational phases, taking into account road, rail and combustion plant related emissions and cumulative effects.
Croydon University Hospital
London
The team prepared the air quality assessment and helped the NHS Trust to obtain an Environmental Permit for two CHP Plant, which form Medium Combustion Plant (MCP) and Specified Generators (SGs). A detailed assessment was undertaken taking account of the existing boiler, generator and incinerator plant.
Grevenbroich
Germany
The team carried out a quantitative assessment of pollutant emissions released to the atmosphere from a proposed saltcake processing plant in Grevenbroich, Germany. This included assessment of nitrogen oxides, dust and ammonia emissions from cooler, crusher and recovery process stacks upon Germany's land use zoning system.
