Platform for Lighting Effects Experimentation Environments - PLEXE
The objective of the project is to Identify, design, and implement a platform/environment, validated by pilot studies, for the ongoing real-world study of the perceptual, behavioural and physiological effects of light in residential spaces. The Live-In Lab at KTH with its advanced sensing and digital twin infrastructure provides a unique opportunity to study the perceptual, behavioral and physiological effects of lighting , and the ways in which those effects can be enhanced to emphasize their positive impacts, in a real-world scenario. This proposal is for a project (“PLEXE - Platform for Lighting Effects Experimentation Environments”) that identifies, designs, implements, and validates new infrastructural components to be added to the living spaces at the KTH Live-In Lab to support advanced lighting related studies, sensing and adjusting lighting qualities in the residential spaces.

The spectral composition, intensity, distribution, and the time of exposure of light in the spaces we occupy can have profound effects upon our physiology and behaviour. These physiological effects can produce both positive and negative impacts upon our behavior, health and well-being. While some of these effects are well-studied and others are only beginning to be understood, the effects have rarely been studied in real-world living situations – most studies to date take place in controlled laboratory environments. The KTH Live-In Lab provides a unique opportunity to study the perceptual, behavioural and physiological effects of lighting (both daylight and electric light), and the ways in which those effects can be enhanced to emphasize their positive impacts, in a real-world scenario. This proposal is for a project (“PLEXE - Platform for Lighting Effects Experimentation Environments”) that identifies, designs, implements, and validates (through a series of pilot studies) the infrastructural components that would need to be added to the living spaces (and background infrastructure) at the Live-In Lab at KTH to support future lighting related studies, such as sensing and adjusting lighting qualities in the spaces. The Live-In Lab consists of student apartments where data, such as energy- and water usage are monitored ( KTH Live-in Lab ). The flexible environment that also has daylight access with different exposures lends itself to advanced lighting-related studies with resident participants. However, first, the appropriate infrastructure needs to be implemented and tested, physically as well as digitally in the existing digital twin. This projects plans for pilot studies that will prepare for the evaluation of real-world measurable perceptual, behavioural and physiological health benefits for the residents of the Live-In lab living spaces, through directed experimental lighting intervention. The overall goal of the pilot studies and the future investigations is to produce knowledge that informs national and international recommendations and guidelines to support the health and well-being of real-world living and working spaces through lighting. The project will promote sustainable design and the responsible use of energy resources, in relation to supporting human health and wellbeing. Differentiated tracking of lighting-related energy use will also be investigated in the project.
