Sustainability for Planning

We work with you to cover the essential components of any planning applications so that you can reach an approved sustainable building project. There are a number of assessments, studies and strategies that our experts can work with you on to meet and exceed all local sustainability planning policy requirements.

Daylight and Sunlight Assessments

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

Air Quality Assessments (AQA)

To support planning applications, we examine the impact of both the construction and operational phases on the air quality of your development. The impacts are compared against national and local air quality objectives and/or significance criteria defined within relevant air quality guidance. We will give you mitigation measures that can be adopted, and for significant challenges we will use detailed assessments which includes dispersion modelling.

Flood Risk Assessments (FRA)

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. We can deliver Level 1 and 2 flood risk assessments and recommend mitigation measures to manage these risks for all stakeholders.

We also develop Sustainable Drainage Systems(SuDS) to reduce the likelihood and impact of surface water flooding from new developments. This involves the use of systems that 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

Low and Zero Carbon (LZC)
Feasibility Studies and Energy Strategies

We report on your LZC and Energy Assessments to help support planning approval. An LZC study assesses the feasibility of installing low and zero carbon energy technologies and quantifies the anticipated energy savings and CO2 emissions reductions which can be used to gain BREEAM credits and demonstrate compliance with planning requirements.

An Energy Assessment accompanies 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.

Sustainability Statements

Local authorities often require Sustainability Statements to be submitted as part of the planning application. We partner with you to develop these strategic statements by looking at how your development holistically meets or exceeds all local sustainability planning policy. This is an important part of your communication as it can often make the difference in achieving buy-in from local planning authorities and communities.

Thermal Comfort Overheating Analysis

Dynamic simulation modelling is used to ascertain the risk of overheating and maximise occupant comfort within a building. When planning in London 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 expert team based on the modelling outputs.

Ecology, Tree and Protected Species Surveys

Guidance on ecological requirements for planning applications are key for developers, architects and anyone submitting a planning application. Find out more on our Ecology page.

Built Environment

Ensure your business is complying with environmental regulations and certify how you are currently performing.

Understand the perspective of various stakeholders about the function of your building, its efficiency and what needs improving.

Protect notable species of flora and fauna with Protected Species Surveys and Licensing, Bat Surveys, Tree Surveys, Arboricultural Method Statements and more.

Find out your carbon footprint and offset them with solutions made for you.
