Ballygossan Park

In 2020 GV8 (trading as BPG3 at the time) was engaged by The Noonan Construction Company to assess the daylight sunlight levels associated with a proposed LRD development in Skerries. The proposed development related principally to the delivery of 144 residential units including a mix of apartments and townhouses as well as an associated creche and amenities.  

‍

With most of the apartment’s units provided within a perimeter block type arrangement one of the key challenges faced in this project was the need to careful consider balcony placement so that units facing towards the central courtyard could maintain good access to natural light.

‍

Using the findings obtained from early-stage testing GV8 and JFOC worked together to design out some of the pinch points that existed within the preliminary proposal. By completing this exercise at an early stage in the project’s development the costs associated with design changes were tightly controlled.

‍

Key Services Provided Included:

• Vertical Sky Component (VSC) testing to assess loss of skylight access to neighbouring accommodation.

• Annual Probable Sunlight Hours (APSH) testing to assess the loss of sunlight to neighbouring accommodation.

• Sun on Ground (SOG) testing to assess the loss of sunlight to neighbouring recreation spaces.

• Production of supplementary shadow casting imagery.

• Spatial Daylight Autonomy (sDA) testing of all accommodation within the proposed development

• Supplementary Average Daylight Factor (ADF) testing

• Sunlight access testing for all units within the proposed development

• Sun on Ground (SOG) testing of all proposed recreation spaces

‍

Fingal County Council granted permission for this development in February 2023.
