Housing Right-to-Light UK

Christina Galyfianaki completed Daylight and Sunlight assessment studies for hurleypalmeflatt for the following residential developments:

  • Bridge House
  • Yeoman Street 

These studies consider the impacts of neighborhood isolation and daylight factors and over-shading from the proposed development to satisfy the BRE criteria of Right-to-Light “Site Layout Planning for Daylight and Sunlight” (SLP) published by the BRE. They aslo review the new development own daylight factors for selected living rooms and bedrooms as well as the annual isolation level of sunlight received by their windows.

Yeomann Street Residential Development

This is a 40 apartments 4-storey residential block. Daylight and Right-to-light SLP study was accomplished for Hurleypalmerflatt team.This IES/Radiance model also provided the insolation roof capacity for the PVC feasibility study.

Overshadowing to Neighbors

IES / Suncast tool was employed for the shadow path for the proposed development to predict the fall of shadow at midwinter, midsummer and the spring and autumn equinoxes.

Sunlight restriction to neighbors

The SLP (“Site Layout Planning for Daylight and Sunlight”published by the BR) sets the criteria that neighbor windows facing within 90o of due south are considered adversely affected by a new development “ if a point at the centre of the window receives in the year less than 25% of the annual probable sunlight hours including at least 5% during the winter months and less than 0.8 times its former sunlight hours during either period”.
For this case the the Radiance software tool was employed to  review the surrounding residential buildings annual isolation with and without the new development.

Daylight restriction to neighbors

The BRE discretionary guidance states that “a window may be adversely affected if the vertical sky component (VSC) at the centre of the window is less than 27% and less than 0.8 times its former value”.
For this case the the Radiance software tool was employed to  review the surrounding residential building windows VSC with and without the new development.
