| Abstract |
This study analyzes the architectural potential of a Microalgae Facade, focusing on its ability to create a natural lighting environment. A
Test-bed was designed and operated to observe trends in Visible Light Transmittance (VLT) and Solar Heat Gain Coefficient (SHGC). The
VLT data were used in a virtual simulation to calculate indoor floor illuminance, which was then compared to G-SEED Daylighting
Environment Assessment, LEED BD+C New Construction Daylight Option 02 and KS A 3011 Illuminance Standards to assess the Facade’s
applicability. Optical performance data for the Microalgae Facade were collected using the Test-bed. based on relevant patents and window
standards. Simulations were conducted using the Radiance engine and the Ladybug Series plug-in within the Grasshopper parametric modeling
environment. The findings indicate that a Microalgae Facade, with 12 mm hollow layers matching standard window dimensions, can provide
effective lighting functionality in office spaces without disrupting the overall environment. |
