Sustainability for Planning

Eight Associates provides pre-app, planning and early design stage advice for projects across the UK, with a particular focus in London and Bristol. Our planning team has a multidisciplinary service offering that comprises sustainability appraisals and documentation to demonstrate compliance with national and local policies. Our fundamental aim is to ensure that schemes capitalise on their sustainability opportunities while clearly communicating these achievements to planning authorities and the public alike to ensure recognition of a scheme’s credentials and increase the likelihood of gaining planning approval.

We have a range of expert consultants in-house to provide all sustainability reports for planning as required at RIBA Stage 2, Concept Design, which typically includes:

Air Quality Assessments (AQA), including dispersion modelling

To support planning applications Eight Associates examines the impact of both the construction and operational phases on the air quality of a particular development. The impacts are compared against UK air quality objectives and/or significance criteria defined within relevant air quality guidance. Depending on the scale of these impacts the air quality assessment may also discuss the mitigation measures that will need to be adopted. For developments in London, an Air Quality Neutral statement is provided as part of the assessment. Where there is the potential for a development to have a significant impact for local air quality, or new sensitive receptors are being introduced into an area with particularly poor air quality, a detailed assessment of impacts will be undertaken, which uses dispersion modelling to determine the impact for specific pollutants at key locations on or around the development site.

Daylight and Sunlight Impact Assessment

Daylight and Sunlight Impact assessments calculate the impact on the daylight levels experienced by existing neighbouring amenities (dwellings, non-domestic uses, gardens, open spaces) as a result of a proposed development. The daylight impact is measured in terms of VSC, ASPH, No-sky line and daylight hours. This analysis forms an essential component of any planning application that would increase overshadowing or decrease access to natural light on an existing amenity.

Energy Strategies / Energy Assessments for planning

Energy Assessments are the accompanying reports for planning applications for domestic and non-domestic buildings that demonstrate the proposed CO2 emissions reductions over Part L and the financial contribution for ‘zero carbon’ homes. The reports demonstrate compliance with national and local policies and regulations, thus establishing a scheme’s suitability for planning approval and ensuring the approved scheme can achieve its planning conditions at practical completion.

Flood Risk Assessment for planning (FRA Level 1 and 2)

Whether for a residential or commercial site, planners, architects, and property developers need to understand the potential risk of flooding when designing and developing a new site. Eight Associates can assess sites to determine the risk and recommend mitigation measures to manage these risks for all stakeholders involved.

Internal Daylight Analysis

An internal daylight analysis calculates the daylight levels and distribution of the daylight inside a room, which is key tool in the design of a building’s fenestration and form. As well as ensuring the building will receive the necessary levels of daylight and maximise occupant comfort, the analysis can be used to comply with the BREEAM or LEED daylighting credits.

Low and Zero Carbon Feasibility Studies

An LZC study assesses the feasibility of installing low and zero carbon energy technologies and quantifies the anticipated energy savings and CO2 emissions reductions. This report can be used to gain BREEAM credits and demonstrate compliance with planning requirements.

Right of Light

A right of light (ROL) may be acquired by ‘anyone who has had uninterrupted use of something over someone else’s land for 20 years without consent, openly and without threat, and without interruption for more than a year,’ according to RICS. Where development will have any impact on the light received by neighbouring properties it is essential that Right of Light is considered. The Right of Light assessment will calculate the book value compensation and will highlight what options there are for dealing with the resulting ROL issues.

Sustainable Drainage Systems (SuDS) Strategies

Eight Associates develops Sustainable Urban Drainage (SuDS) Strategies to reduce the likelihood and impact of surface water flooding from new developments. This comprises encouraging the use of design measures to mimic ‘natural’ drainage by adopting techniques to deal with surface water runoff locally, through collection, storage and cleaning before allowing it to be slowly released back into the environment.

Sustainability Statements

Local authorities often require Sustainability Statements to be submitted as part of the planning application. Eight Associates works with clients to develop these strategies by looking at how the development holistically meets or exceeds all local sustainability planning policy.

Thermal Comfort Overheating Analysis

Dynamic simulation modelling is used to ascertain the risk of overheating and maximise occupant comfort within a building, it is also necessary to demonstrate compliance with the London Plan. The analysis aims to ‘design out’ and reduce need for active cooling as much as practically possible. Guidance on U-values, thermal mass, airtightness, shading and the optimal ventilation and mechanical services strategy can be provided by our team based on the modelling outputs.

Eight Associates has in-depth experience of assisting design teams with the planning process, providing a comprehensive, practical and hands-on approach to service the project effectively. We have a robust understanding of what planning officers will require relating to sustainable design through our years of working on hundreds of planning applications across London, Bristol and the UK.
