In my travels completing compliance checks and lighting surveys for various companies and entities, I have become more aware of the ambient lighting conditions after dark in both regional and metropolitan areas. Whilst I acknowledge there are more and more exterior lighting installations, I have noticed what I believe to be a bigger impact on the environment. Many years ago when I was the Australia/New Zealand President of the IESANZ, I was asked to join the Dark Sky Association by Reg Wilson. After a number of both philosophical and practical discussions, Reg and I agreed on a way forward for the two organisations to work together. I look back now and realise how much those conversations changed my way of thinking about the impacts of what was more commonly know then as Sky Glow. The subject caused a lot of discussion over the years and eventually had a number of standards groups believing some sort of recommendations or controls should be suggested to designers. These discussions led to the production of the first version of 'AS 4282(Int)-1995 (Expires 5 December 1996) - Control of the obtrusive effects of outdoor lighting'. This was an interim Australian Standard that really got designers thinking about the ambient effects of their designs, a good thing I believe.
