Abstract The Research was conducted to identify the optimal operating period of microalgae facades based on changes in the indoor environment. The research followed several steps: a literature review, collection of visible light transmittance (VLT) data through scale model testing, lighting simulations using the collected VLT data to calculate floor illuminance, comparison of the results with LEED criteria, and analysis of the optimal operating period under conditions of extreme changes in the light environment. First, the suitability of using scale model experiments and simulations was reviewed, along with an examination of evaluation systems and criteria for light environment analysis. Next, during the scale model testing phase, a microalgae facade model with specifications similar to typical architectural windows was created to gather VLT data. This data was then used as input for light environment analysis, employing the Radiance engine and Ladybug Series Plug-in within the Grasshopper platform to calculate indoor illuminance levels. As a result, the optimal operating period for maintaining a stable and uniform light environment with a microalgae facade was determined to be 9 days.
