Daylight / Sunlight modelling
Creating healthier spaces for people, places and the planet
Analyse Daylight and Sunlight with IN2's advanced simulation techniques
IN2 undertakes detailed daylight and sunlight assessments using recognised methodologies and local planning guidance. We model existing and proposed conditions to evaluate daylight distribution, overshadowing and sunlight availability.
Robust daylight and sunlight analysis supports planning approval, protects residential amenity and informs better massing and façade design.
IN2 offers the following daylight/sunlight services:
Daylight and sunlight assessment reports
Overshadowing and sunlight availability analysis
Planning submission support and responses
Amenity Sunlight Availability
Shadow Diagrams
Daylight Availability
Neighbouring Daylight Analysis
Development Sunlight Analysis
Sunlight availability
IN2 utilises building simulation techniques to ensure best practice Sunlight Availability for applicable rooms within both new and existing developments. This is undertaken by ensuring Annual Probable Sunlight Hours are adequate for applicable rooms to new developments, whilst verifying that no impact to existing buildings will be invoked, in accordance with BRE Methodologies.
Amenity sunlight availability
In addition to ensuring that rooms can benefit from enough sunlight, IN2 undertake Amenity Sunlight Analysis in order to verify that external spaces, both new and existing, can achieve adequate exposure to potential sun as defined within BRE Best Practice Guidelines, ensuring they can be utilised as useful amenity spaces.
Shadow diagrams
Detailed Site Sunlight and Shading Analysis is also undertaken using lighting simulation tools, illustrating predicted shadow casting for existing and proposed developments on a comparative basis of various seasons and hours for the site-specific location.
Daylight availability
Building simulation techniques are utilised by IN2 in order to predict daylight availability for new and existing developments. This is undertaken by calculating Vertical Sky Component which is a measure of how much sky view can be received at window positions.
Internal Daylight Analysis
IN2 perform simulation-based Internal Daylight Analysis, predicting daylight factors in order to be able to report both Average and Median Daylight Factors in accordance with BS.8206-2 and EN.17037. Where possible, we utilise Revit based geometry for analysis, minimising risk of remodelling translation error and enabling large developments to be assessed rapidly.
