The Building Engineering Services Association (BESA, formerly B&ES) has appointed Tim Rook to the new senior position of technical director and Jack Verber as technical assistant.

Tim was previously head of build design at Eon Community Energy, where he led a team of engineers in the design and delivery of ecentralised energy systems, including: London’s Citigen, which features 9MW of combined heat and power supplying a 25MW heat and 10MW chill district system; the UK’s first commercial solar thermal plant; and some of the largest residential district heating systems.

He is a member of the Institute of Mechanical Engineers and the Chartered Institution of Building Services Engineers, and has worked in a wide variety of m&e contracting businesses, as well as manufacturing, the energy industry, with particular emphasis on renewable and environmental technologies, most notably biomass, heat pump and photovoltaic systems.

Jack Verber graduated with honours in mechanical engineering from the University of Bristol in 2013 and, before joining the BESA, he spent 14 months with Schlumberger in Bergen, Norway, as a field engineer working on exploration oilrigs in the North Sea.

Chief executive Paul McLaughlin said that the two appointments underlined the BESA’s commitment to leading the technical agenda across building engineering services, to the enhancement of its suite of industry specifications and guides to good practice, and to ensuring that its members remained in the vanguard of technological innovation and development.
