Quantification methods for personal light exposure patterns

TU/e BE Start Stimulus Grant, 2024-current

Personal light exposure patterns (i.e. the light an individual gets exposed to over time) can be quantified using a variety of methodologies. Currently applied methods include light dosimetry, environmental light measurements, lighting simulations, and self-reported scales. However, each method entails certain assumptions and inaccuracies. The project’s aim is to improve the accuracy of quantifications of personal light exposure patterns by refining and/or combining these methods.

BL-group: PhD student Sietse de Vries works on this project. Juliëtte van Duijnhoven is supervisor in this project.

LoLiPoP-IoT

EU HORIZON, Chips Joint Undertaking, 2023-current

In LoLiPoP IoT innovative Long Life Power Platforms will be developed to enable retrofitting of wireless sensor network (WSN) modules in IoT applications. This includes the development of algorithms to perform FUNCTIONALITIES like asset tracking and condition monitoring (for predictive maintenance). They can be used in APPLICATIONS such as industry 4.0, smart mobility and energy efficient buildings. The Workplace Vitality Hub provides a sandbox to test both the infrastructure needed as well as the influence of conditions in our daily environment that we can and should measure, control, and tune to optimize our work environment.

BL-group: Mariëlle Aarts is involved in Work Package 7 focusing on Use cases.

LIGHTCAP

EU HORIZON 2020 MSCA-DN, 2020-current

The LIGHTCAP project is a European Training Network under the Marie Skłodowska-Curie actions framework. LIGHTCAP aims to provide a strong, innovative and necessary impulse to our insights in the intricate and complex relationships between light, perception, attention and cognition. In LIGHTCAP, 15 early stage researchers will be trained in a joint programme between 7 academic European partners.
More information about LIGHTCAP.

BL-group: PhD student Myrta Gkaintatzi-Masouti works as one of the 15 early stage researchers on this project. The project focus is on implementing the effects of light on humans in the lighting design process. Mariëlle Aarts is PI in this project. Juliëtte van Duijnhoven is mentor in this project.

Past projects

VETHO

Company project supported by VELUX, 2022-2024

This project in which VELUX and TU/e focus on Home Offices (VETHO) is a company project as part of an EngD program. The project’s overall goal was to create a recommendation guideline for home office workers to receive the right amount of light, daylight, at home. EngD trainee Verena de Kok successfully achieved this by developing the DaylightGuide! On April 10th, 2024, Verena presented the (development of the) tool at the Daylight Talks event in Eindhoven.

BL-group: EngD Verena de Kok was involved in this project. Juliëtte van Duijnhoven was her academic supervisor.

IntelLight+

Eindhoven Engine project, 2020-2024

Human-centric lighting should benefit users, but the practicality of this is no clear-cut process. Building on the latest insights into new light sources, Internet of Things and how lighting impacts human functioning, the project takes an integrative approach to developing algorithms to infer and even predict user context to accommodate user needs and preferences as well as innovative lighting and new design methodologies that allow optical designs which promote optimal efficiency, higher optical quality and better utilization.

BL-group: EngD Sietse de Vries was involved in this project. Mariëlle Aarts was his academic supervisor.

SMART-SPACE

EU Interreg North-West Europe, 2018-2021

SMART-SPACE aims to facilitate the uptake of smart lighting in small/mid-size municipalities to enhance energy-efficiency and reduce CO2 emission. Using smart sensors attached to light poles, street lighting intensity can be automatically adjusted to the actual local needs, realizing 60% reduction in light energy consumption. However, until now implementation occurred mainly in small scale pilot projects, indicating that to reach the low carbon objectives requires a strong, transnational collaboration to move beyond piecemeal solutions.
More information about SMART-SPACE.

BL-group: Sila Akman Asik was involved as EngD trainee in the project. She developed a user experience toolbox for smart urban lighting solutions. Juliëtte van Duijnhoven was her academic supervisor.

OPTILIGHT

NWO High Tech Systemen en Materialen (HTSM), 2016-2022

The overall goal of this project is to make lighting control systems more centered towards the human user. This requires not only better insights in how humans experience light but also demands quantified models and optimization algorithms that are executed by automated lighting control systems. The project was funded through the NWO HTSM scheme and was conducted in the context of an existing strong bilateral cooperation between TU/e and Philips in the Intelligent Lighting Institute.

BL-group: PhD student Thijs Kruisselbrink was involved in this project. Supervisors in this project were Alexander Rosemann, Evert van Loenen, and Rajendra Dangol.

Creating Healthy Environments Hospitals

Impuls Spark project, 2015-2019

One of the major societal challenges we are facing today is transforming healthcare so it becomes sustainable in terms of costs, availability and outcomes. In the project “Creating Healthy Environments – Hospitals” the focus is on increasing healthcare effectiveness and outcomes by improving environmental conditions for patients, but particularly for professionals working in hospitals. This Impuls SPARK Project hosted one PhD student from Utrecht University of Applied Science with a focus on sound and one PhD student from TU/e with a focus on light.

BL-group: PhD student Mariëlle Aarts worked on the light-related topic in this project. Supervisors in this project were Alexander Rosemann, Evert van Loenen, and Helianthe Kort.

Creating Healthy Environments Offices

Impuls Spark project, 2015-2019

The general approach was to identify lighting solutions for the built environment that form a balanced consideration of energy and health-related aspects for the building occupants in open office environments. This project was a Impuls SPARK Project and consisted of 4 PhD projects; two industrial PhDs and two full-time TU/e PhDs.
Here you can find more information about this project.

BL-group: PhD students Christel de Bakker, Sanae Chraibi, Juliëtte van Duijnhoven and Tatiana Lashina worked on this project. Supervisors in this project were Alexander Rosemann, Evert van Loenen, Helianthe Kort, Myriam Aries and Mariëlle Aarts.
