Compton Cottage
The proposed development at Compton Cottage was constrained by its location which limited the ability to use openable windows as an appropriate way to reduce overheating potential.
A 3D dynamic model was created to assist in the development of a solution for compliance with the onerous requirements of Building Regulations Part O which imposes strict limitations on the use of openings where noise is a persistent, nighttime issue. In this instance, the buildings location dictated that windows should be closed at night.
Working with the architect, an appropriate glazing and ventilation specification was developed to allow compliance with the rigorous requirements of this new and challenging aspect of the Building Regulations with a full, written report provided in support of Building Control Approval.

Overheating Analysis
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.
