At the huge Spinningfields development in Manchester, Commtech was responsible for mechanical and electrical commissioning for three of the main buildings, including commissioning management for two of them.

Planning ahead — the choice between an A and a G

Commissioning is a neglected art, but the growing legislative responsibilities on building owners means it is about to come into its own, says MIKE MALINA.

Advanced commissioning in the palm of your hand — Comdronic’s AC% commissioning instrument.

Commissioning instrument meets new challenges

A commissioning device that is ideally suited to the large differential pressures associated with differential-pressure control valves (DPCVs) is Comdronic’s AC5.

Crane valve
Designed for use in variable-volume systems is Crane’s MotoBalance motorised balancing valve.

Balancing valve designed for variable-volume systems

A motorised balancing valve from Crane Fluid Systems is designed for circuits where the combined functions of actuated regulation and flow measurement are required.

Swiss Re
The benefits of SAV commissioning modules for fan-coil units have been exploited on 19 floors of the Swiss Re building.

Commissioning elegance for elegant skyscraper

SAV commissioning modules for air-conditioning systems using fan-coil units are used on 19 floors of the Swiss Re building in London. They were specified by consulting engineers Hilson Moran Partnership.

By combining commissioning and five other functions into one valve, Oventrop’s Cocon 4 can reduce installation time by up to 25%.

Six functions into one valve for fan-coil units

Installation time savings of up to 25% are said to be possible using Oventrop’s Cocon 4 control valves on fan-coil units. These multi-function control valves were specially developed for fan-coil units and chilled beams.

CIBSE’s new president reflects on industry issues

In his long career in the building-services industry, the new president of CIBSE has seen many changes — not necessarily beneficial to the industry but nevertheless pointing the way to improvement.

Keith Marshall
Championing the skills agenda of the building-services sector — Keith Marshall on the role of SummitSkills.

Securing the workforce of the future

Sector skills councils have been set up to champion their industry’s skills agenda, as Keith Marshall of Summitskills explains.

Catching them young — CIBSE’s involvement in Imagineering is aimed at getting eight- to 16-year olds interested in engineering as a future career.

Nurturing interest in building-services engineering

Its special position in the industry makes the Chartered Institution of Building Services Engineers well placed to stimulate interest in a building-services career.

The largest and best known fuel-cell installation in the UK is at Woking, and was the first CHP and photo-voltaic system in the UK. The Pool in the Park project combines fuel-cell and conventional CHP systems with photo-voltaic panels to produce heat for space heating, swimming-pool water, domestic hot water for showers and electricity distributed over private wires for the whole leisure complex — which also includes the Leisure Lagoon and Leisure Centre. Surplus electricity is exported over the local distribution network to other customers.

Celling the hydrogen economy

The future is a hydrogen economy, and good old CHP could lead the way to a new way of producing and distributing power around the UK.

Domestic air-conditioning market starts to rear its head

While a domestic air-conditioning market is starting to emerge in the UK, it is developments in the commercial sector that are most interesting. FRANCESCO NAMBOKA has the details.

CIBSE vice-president David Hughes (left) discusses the instrumentation in Trox’s new test chamber and mock-up facility for fan-coil units with laboratory manager Mick Holland and commercial director Amanda Sayers.

One of the most effective methods of air filtration currently available is the plasma filter, which was first designed for hospitals.

Effective filtration in air-conditioning units

Air-conditioning units that only cool the air are only addressing part of the equation. Air filtration to remove and neutralise bacteria is just as important, as STUART MADDOCK explains.

Why hide them? Denco’s restyled close-control air-conditioning units are designed to be left on view rather then be concealed.

Denco adds style to close-control air conditioning

Underfloor air conditioning requires less space

Advanced Ergonomic Technologies has added a slimline fan tile unit to its Flexible Space Concept, which comprises Hiross underfloor air conditioning, raised access flooring and demountable partitioning systems. Its shallow depth enables underfloor comfort cooling to be used on refurbishment projects where ceiling-based air conditioning is impractical because of restricted floor-to-ceiling heights.

Over 6000 m2 of Kingspan’s KoolDuct preinsulated ducting has been used in risers and ceiling voids in this NHS treatment centre in Birmingham.

KoolDuct is best treatment for new NHS centre

Conditioned air for the £32 million NHS Birmingham Treatment Centre is distributed by ductwork based on 6000 m2 of Kingspan’s KoolDuct system. It was installed by Crown House Engineering, whose Gary Hague explains, ‘The fact that KoolDuct is pre-insulated and does not require additional lagging made it ideal because of the confined ceiling void, which had to carry all services, as well as the ducting. In addition, the ease and speed of installation was a significant advantage on a project where there was a number of other trades on site.’

VRF air conditioning has been provided for a bank in Mayfair without outdoor units by using Mitsubishi Electric’s WR2 system connected to the landlord’s condenser water circuit via a plate heat exchanger.

VRF in refurbishment project is linked to landlord’s condenser water circuit

Because visual and noise restrictions did not permit condensing units on the outside of the Mayfair branch of Halifax Bank of Scotland in London, Air Movement Design devised an air-conditioning system for this refurbishment project based on Mitsubishi Electric’s WR2 water-cooled VRF system.

Meeting the cooling and heating requirements of this extension to the headquarters of Marshalls Construction in West Yorkshire is a Toshiba SMMS VRF system.

The lessons of history

There was a time when those knowledgeable and experienced in the art of building-services engineering at all stages of the supply chain could work together for their mutual benefit and the benefit of the client. CIBSE’s new president, Donald Leeper, has 40 years’ experience in the industry and recalls in his presidential address how in the 1960s consultants routinely worked with key manufacturers to improve design solutions and aid product development. It was integrity of the same level as the professional quantity surveyor that made such co-operation possible.
