Application

Design takeaway

How to apply

When designing new buildings or retrofitting existing ones, consider a two-pronged approach: optimize the building envelope for daylight penetration in peripheral areas and design internal spaces to channel light effectively into core areas, all validated through energy simulation.

Project actions

01When researching daylighting, consider how different window sizes, shapes, and placements affect light levels.
02Explore how internal design elements like reflective surfaces or open floor plans can help distribute natural light further into a building.
03Investigate the use of simulation software to predict the energy savings from your daylighting designs.

Method & Evidence

AimTo develop and validate an integrated design and simulation methodology for daylighting that precisely quantifies energy efficiency improvements in buildings.

MethodIntegrated Design and Simulation

ProcedureThe methodology discretely conceptualizes and designs peripheral zones of the building envelope and central core areas. Peripheral zones utilize average daylight factor and optimized window-to-wall ratios, while core areas are designed to attract daylight from roof structures and openings. Building energy performance simulation tools are used to validate the energy efficiency of these techniques.
