ANALYSIS OF EXISTING DAYLIGHTING CONDITIONS IN SELECTED LIBRARY SPACES IN KADUNA, NIGERIA
* Corresponding author: adtachio@gmail.com
Abstract
Purpose: This study investigates the existing daylighting conditions in selected library spaces in Kaduna State, Nigeria, recognising that abundant natural light in the tropical wet-dry climate is underutilised. It aims to assess the visual comfort, light distribution, and energy efficiency challenges associated with traditional daylighting design approaches.
Design/methodology/approach: The study analysed three library case studies using climate-based daylight modelling and field measurements. Tools such as Velux Daylight Visualizer and Revit® were employed to evaluate illuminance levels and glare conditions. User surveys were also conducted to understand seating preferences regarding lighting comfort.
Findings: Results revealed uneven daylight distribution, excessive glare near windows, and insufficient illumination at core reading areas (often
