This seminar is a CPD event organised by the College of Engineering and Built Environment, DIT, in conjunction with CIBSE Ireland and the Society of Light & Lighting.
It will be held in DIT Kevin St room KEG-007 on Thursday, 19 October starting 6pm
Commencing with warm finger food, sandwiches, and tea/coffee from 5.45pm with the presentations beginning at 6.30pm sharp.
The seminar is based on designing interior lighting for appearance and surrounding brightness, rather than designing lighting for functionality and vision only, as is the case at present. Indeed, it seems remarkable that most interior lighting design is still based on methods first developed in 1916. Despite many proposals, minor variations and additions since, the illuminance on the horizontal plane remains the dominant metric in lighting installations worldwide, despite the fact that the type of work and visual task has changed dramatically in recent years.
So, what then is good quality lighting in a modern interior? According to the SLL Code, this allows you see things quickly and easily without visual discomfort, but also serves to raise the human spirit. Up to now this latter higher ambition to raise the spirit has largely been left to dedicated lighting designers implementing imaginative and creative designs. Lighting Codes tended to settle for ensuring avoidance of bad lighting.
The SLL Code states — “Lighting recommendations are useful for eliminating bad lighting and following recommendations is usually enough to ensure indifferent lighting is achieved… and bad lighting avoided”. There is little ambition in the Code that those adhering to the Code will achieve good quality lighting.
It is clear that working and living environments generally are changing with increased use of screen technology and consequently, user demands for higher levels of comfort and societal demand for lower energy use are increasing. The above and the ubiquitous use of LED lighting offers opportunity for legislators and practitioners to consider a paradigm shift to a new lighting design methodology.
In 2010 Christopher (Kit) Cuttle — a New Zealand lighting designer/researcher — proposed a radical new approach to lighting design. He aimed to close the gap between the lighting design community and the engineering community which relied heavily on horizontal illuminance (Eh) as the dominant metric in design, and argued that a new design methodology was appropriate. This new method would be achievable by consultant engineers using reasonably-standard techniques and software for all but the most demanding and high-end projects. In other words, the aim was to raise the standard of lighting generally to good quality lighting, rather than the indifferent quality lighting accepted as the norm.
Kit proposed we move from designing lighting purely for visual needs to providing lighting that contributes more positively to people’s comfort and appreciation of the spaces they work in and inhabit. This means working towards designing lighting for appearance and surrounding brightness and then focusing on visual needs, rather than designing lighting for functionality and vision only.
Further to that proposal Kit collaborated with the Dublin Institute of Technology in endeavouring to get lighting legislators to change their codes and to persuade engineers to change their practices in this regard. Underpinning this is multiple PhD research, the findings of which will be presented at this event.
