The building services industry remains one of the UKs most dynamic and wide ranging industries, with many sites facing high power demand, embedded generators and renewable power, as well as more complex control systems. Developers are faced within increasingly complex systems, tight project time scales and the need to ensure that all equipment is correctly specified and designed.
