IES NSW Technical Meeting & National AGM November 2018.
JHA was delighted to be able to host the Illuminating Engineering Society (IES) at their Sydney Studio for the National AGM and technical meeting. The night also included a panel discussion on “Lighting for Being”.
The panel saw a number of experts in various fields discuss a wide range of topics surrounding the use of artificial lighting in our interior and exterior environments and touched on some of the considerations this has on health and wellbeing.
A range of questions were put to the group including upcoming trends in lighting, the implications of external lighting on the surrounding environment and the night sky, the challenges associated with balancing creative design with compliance to standards and guidelines and the proposed launch of an artificial moon into orbit over China’s Chengdu province by 2020.

Ashleigh Bretherton, Senior Lighting Designer, Steensen Varming.
The conversation opened with Lesa outlining some of the effects that light pollution has on our night skies and the challenges faced by astronomers when gazing at the stars above. Lesa explained how light spill from artificial lighting installations can impact on the visibility of the night sky even at significant distances from densely lit urban areas.
Lesa explained how areas such as Warrumbungle national park – Australia’s internationally recognised dark sky park – can be impacted by lighting as far as 500km away in Sydney. She also discussed how controlling the spill of light can help us to minimise the impacts of undesirable light pollution.
From here, the discussion then moved onto the carefully consideration of lighting design practices in our external environments. Ashleigh provided an account of her vast design experience in the external environment.
Ashleigh challenged some of the standard lighting practices of achieving bright, uniformly lit spaces outside. Instead she suggested we should opt to purposefully create contrast and embrace the darkness when it is suitable. She also discussed the importance of community involvement in the design process being of great importance to the utilisation and care of our external spaces.
With his extensive experience in the architecture, Michael was able to provide a unique insight into the role light plays in setting the scene of a space. He talked about how light can be used to inform a space and provide valuable cues to those who use it, from wayfinding through to how we perceive spaces differently with different lighting techniques.
Michael also touched on the importance of post-project support and the education of end users in managing and getting the most of their lighting control systems.
Lawrence elaborated on some of the sustainability initiatives that we see in our built environment in terms of lighting control systems and LED lighting technologies. He highlighted how as engineers and designers we have the opportunity to provide added value to our clients with education and more detailed handover of building management systems.
Lawrence also discussed how we can use standards and guidelines in a way such that they inform our design process rather than consider them as design constraints.
Wendy discussed the emergency of new lighting technologies and how things are shaping up in the world of LED technology. She discussed the limitations of retrofit solutions and how that limits the effectiveness of optical technologies. She also encouraged lighting designers to step out of the traditional moulds of lighting design and start using things such as colour, and greater degrees of optical control to create more novel solutions to our lighting problems.
The final point of discussion was around the artificial moons proposed to be launched into orbit to provide night lighting to the Chengdu province in China. Lesa detailed some of the logistical challenges of aiming and controlling reflected light from something in a high earth orbit over a small city.
Ashleigh discussed some of the cascading effects that this would have on existing lighting installations and the greater impacts on the wellbeing of the people and the environment.
