ABSTRACT
Architects typically design services for small buildings, involving plumbers and electricians for detailed expertise on site; as services installations have become more sophisticated, so have the regulations controlling their installation in buildings. The number of specialist designers, suppliers and installers has increased to cover demands for detection and alarm systems for fi re, security, air quality, etc.; audio and video systems; ambient energy systems, rainharvesting and grey water recycling systems; ventilation and air conditioning; more sophisticated lighting and control systems for all services either on site or remotely.
