Lees Yard, Chichester

Lees Yard, Chichester

The proposed development at Lees Yard consists of the construction of 38 no dwellings of a mix of types. Located next to a busy road and farm yard, the site information was accompanied by a noise report which outlined the restriction imposed on differing areas of the site based on their on site testing.

A 3D dynamic model was created to assist in the development of a solution for compliance which took into account multiple factors throughout the site included those outlined within the supporting noise report.

Working with the developer through various rounds of calculations, a solution for those units which did not quite meet the requirements of Part O were found and a finalised report issue confirming compliance, and the method to which this was achieved.

Located on the south coast, the Lees Yard development consisted of the implementation of house types which were required to meet the requirements of Building Regulations Part O.

Conducting overheating analysis using Dynamic Thermal Modelling (DTM) is a crucial step prior to planning. Whilst this has been a consideration within London for major developments for many years, the impact of the implementation of this policy is now nationwide.

Whilst a simplified approach is possible, this may not always suit bespoke designs which incorporate large quantities of glazing, and can in some cases be restrictive to the overall design process. Dynamic modelling provides a precise evaluation of overheating risk, generating customised results and recommendations for compliance.

Referencing CIBSE TM59 methodology, Building Regulations Part O incorporates other considerations which need to be balanced within the buildings overall design including security, safety, and any mechanical ventilation system.

The DTM process reviews building materials, thermal mass, local shading, local weather data, building occupancy, and employs approaches to limit solar gains and eliminate excess heat.

Our experienced overheating modellers assist developers in completing comprehensive assessments, offering specialised guidance to comply with new Building Regulations and London Plan policy.

We’ll support you to:

  • Assess and mitigate overheating risk
  • Understand associated costs
  • Develop coordinated solutions
  • Deliver comfortable, energy-efficient spaces
