Posted By Kieran J Duignan Mal From some years' experience of working in construction, I would be extremely wary of an invitation as a 'charismatic' speaker. Those I've known who were most effective avoided such a noose around their necks. If you specify what results do you want your speaker to achieve, and the preferred style of his or her behaviour, you are more likely to get a satisfactory shortlist. Without the Apocalypse.

Posted By Robert K Lewis Mal I still think there is a blurring of meanings here. Sustainable construction is about the environmental issues assessment commencing as early as the planning stage with a view to reducing the impact of the structure, and to an extent the selection of materials. The concerns about new hazards for H&S that might be created have been in my view overrated but I would like to know how your current speaker frames the issues. The H&S issues, do not appear for me to be novel but I do accept that there are bits stuck on to give an outward appearance of env. friendliness but which increase the H&S risks. I am thinking of the Tesco example here where mini-wind generators powered the tills etc in the store. They were located right out on the edge of the front canopy with no means of securing personal safety from falls. Sustainable change has been and continues to be a real H&S issue. This is a different narrative though! Bob
