Program Spotlight: Human-Centric lighting in focus

02 Sep 2019

Made up of 8 different streams all focused on different areas of lighting and design - the 2019 program for the IESANZ Conference is shaping up to be an unmissable event filled with new ideas, collaboration and learning. 

Over the next few weeks we will highlight specific session streams and provide a bit more information on their topics and what to expect, starting with ‘Human-Centric Lighting in Focus'.

Human-Centred Design recognizes the importance of behavioural, emotional and environmental contexts in the creation of lighting, products and usable spaces. It encourages designers to see product users as real human beings with real, complex lives, instead of just as numbers.

In this session you will hear from Tim Shotbolt, Jennifer Long, and Zahra Hamedani, three experts in their field:

Lighting: Human-Centred Design with Radiation
Tim Shotbolt PhD, RLP, LFIES

In this presentation Tim will discuss how using a human-centred approach to design and development has the potential for substantial economic and social benefits for users, employers and suppliers. This could in turn increase productivity, operational efficiency and accessibility - ultimately improving the user experience and reducing discomfort and stress.  Lighting design is human centred design, however, most biota on Earth have different sensitivities and sensitivity ranges to radiation than humans.  Greater sensitivities in both the blue and red parts of the visible spectrum as well as sensitivities in the ultra-violet and infra-red regions; essential aspects of biophilic design.  Longer-term survival of our biosphere means ‘sustainability' must be more than simply energy consumption objectives.

Lighting for Control Rooms - Not all Rooms are the Same
Jennifer Long, Visual Ergonomics Pty Ltd

Control rooms are integral to many industries - but not all control rooms are the same.

This presentation describes a human-centred approach used by an architect-ergonomist team to provide very early schematic design advice for control rooms. Better design outcomes could be achieved if lighting designers worked in multidisciplinary teams with other building stakeholders, video-display system integrators, architects and ergonomists.  Such an approach would assist the lighting designer to understand specific end user requirements for individual control room projects. This knowledge could be used to develop lighting design solutions which address the unique requirements of the control room. 

A Feasibility Study using Ocular Behaviour as an Indicator for Assessing Glare in an Office Setting
Zahra Hamedani, Griffith University

Zahra will discuss research around how ameliorating office worker satisfaction and productivity in workplaces through daylighting is achievable when inherent visual discomfort and glare are minimized. However, given the subjective nature of discomfort sensation, some uncertainty exists about discomfort glare predictive model accuracy. In this research, further to subjective glare ratings, involuntary physiological responses were explored. Ocular and pupillary metrics, including mean pupil size, pupillary unrest, fixation rate/duration, and blink rate/amplitude, were investigated. Most of the studied metrics showed significant differences between low and high glare situations, with blink amplitude having the largest effect size suggesting this variable may be a reliable indicator in the presence of glare.

This session will discuss and share the results from this study.
