Abstract

Ensuring optimal physical comfort, the need for a comprehensive evaluation of the performance of building systems was established. This investigation endeavors to meticulously scrutinize illuminance and light power density metrics across distinct temporal segments (morning, noon, afternoon, and night), as well as the dynamism of daylighting and artificial lighting presence within Tower C and D of Universitas Multimedia Nusantara (UMN). Noteworthy for their incorporation of double skin façades, these edifices serve as focal points of inquiry. The empirical findings reveal that illuminance levels within classrooms and offices, irrespective of natural or artificial lighting, consistently fall short of the prescribed 350 lux threshold based on SNI across most floor levels. The efficacy of the double skin façade manifests in a discernible attenuation, diminishing illuminance ingress to the building by approximately 50%, and precipitously by up to 90% about window fixtures. Furthermore, the analysis of light power density underscores an energy efficiency quotient hovering around 60%. These empirical insights are intended to serve as a foundational resource for guiding the initiation of Net Zero Healthy Greenship certification endeavors.

Abstract

Office buildings in urban areas are most likely situated and clustered close to one another, which can impede the penetration of natural sunlight. In contrast, artificial lighting maintains constant intensity and color throughout the day. This paper proposes a strategy to address these limitations by incorporating dynamic lighting systems that automatically adjust the light intensity and color. At this development stage, an IoT-based microcontroller device is deployed. The data collected will be processed and displayed on a web page, providing a monitoring tool for light intensity in the work area. This system's dimming and color adjustment features will be tailored to dynamic lighting characteristics. By conducting laboratory-scale trials using the system design that has been made, it is estimated that 1 lamp can save 17% of electric power compared to if the lamp is lit at maximum conditions continuously.
