Daylight and Sunlight Assessments

Daylight and Sunlight Assessments can be required for either BREEAM, Code for Sustainable Homes or as a planning condition. These assessments can cover various aspects such as;

  • Assessing the quality of internal daylight within a proposed building
  • Predicting the daylight/sunlight impact of a development at the windows of adjacent buildings
  • Predicting the daylight/sunlight impact of a development on adjacent public areas or development land
  • Right of Light assessments at existing dwellings

MACH are able to provide assessments for all of the above. Daylight assessments are carried out as per guidance in the BRE document ‘BR209 Site Layout Planning for daylight and sunlight – a guide to good practice’ or BS 8206.

MACH are able to provide detailed daylight impact and internal daylight analysis to tight deadlines and for a competitive fee.

Daylight & Sunlight Impact Assessments for Planning

For most new urban developments that are either multi-storey or close to existing properties, it is likely that a daylight impact assessment will be required. These assessments are required to ensure that the quality of light at adjacent properties is not significantly impacted upon by the development.

This is typically assessed through 3D modelling of the proposed development and adjacent areas. Modelling software is used to predict the Vertical Sky Component (VSC) values at the existing dwellings before and after the proposed development.

Internal Daylight Assessments for Planning

For developments that have tight site restraints or are part of a refurbishment, it is common for planning conditions for an assessment of internal daylight quality. This is an assessment to demonstrate that occupied areas (living rooms, kitchens, bedrooms) are able to achieve good levels of daylight. Mach will predict the Average Daylight Factor (ADF) for each room, to assess against minimum BRE guidelines.
