I am an experienced and enthusiastic chartered engineer who is an expert in all elements of interior and exterior lighting with the exception of theatre and events. Through a balanced career I have accumulated vast knowledge and experience in maintenance, design, material procurement, contracts and education. I have qualifications in lighting and electrical engineering, and in management with economics. I orchestrated significant energy use reduction programmes long before they became fashionable.For maintenance: I have managed multi-million pound contracts not to mention similarly sized electricity bills; I know how to compile cost-effective programmes, both what to do and when, and what not to do; and I have an in-depth knowledge of how things work.In design: I am comfortable with the concept that lighting is a science and an art; I understand the importance of surfaces, reflection and glare; and I have worked at many scales, one room to complete building, and in the exterior short lane to long motorway. In addition I have experience in architectural lighting, and was a team leader for many exciting projects in conservation areas in and around Glasgow. Furthermore I have experience in the intriguing challenges of tunnel lighting.For material procurement: I examined the task at hand and purchased to last taking into account the enemies, i.e. voltage variation, heat, water, corrosion, theft and vandalism.In contracts I have been particularly proficient in writing for different scenarios e.g. measured, lump sum maintenance, design and build, material procurement and electricity supply.More recently I have lectured extensively on lighting design, the workings of the human visual system and the different impacts of light on human health and in particular on circadian rhythms. Much of this has been in the context of dementia environments where things can be a bit tricky.
