Mechanical and electrical services for the 100 000 m2 headquarters of Barclays Bank in London were designed by hurleypalmerflatt to meet future-proofing requirements by being able to accommodate one person per 7.5 m2, compared with the British Council for Offices guideline of one person per 10 m2. Substantial future plant space and riser capacity is available to support this growth. |
Delivering value engineering
Published: May 2007
Delivering value for building services is not the same as reducing costs. Indeed, a small reduction in cost could reduce value by much more. JIM HARRISON presents a consultant’s perspective.

Finding more value in offsite fabrication
Published: May 2007
Offsite fabrication is the ultimate in value engineering for building services. We just have to be better at selling it, says PAUL COOPER.

Vital Energi sees variable speed drives as much more cost effective than control valves — hence their use in the new energy centre of the Natural History Museum with its CHP engine, absorption chillers and boilers. |
The value of variable-speed drives is not in the balance
Published: May 2007
No-where in the new energy centre of the Natural History Museum is there a balancing or commissioning valve. Vital Energi, which manages the centre believes that using variable-speed drives with all fans and pumps is inherently a far better approach.

The ubiquitous combination of Ethernet and TCP/IP allows a single network to be used to carry all the data for boilers, chillers and air-handling plant — as well as all the other building systems. |
Better value in building- management systems
Published: May 2007
MIKE WILLIAMS believes that more powerful and less expensive technologies have overtaken dedicated building-management systems — presenting potential purchasers and users with the ability to have all the useful functionality required, but at a lower price.

The Simmtronic lighting-control system in the new London headquarters of a major law firm provides extra value by controlling fan coils. |
Lighting controls also embrace fan coils
Published: May 2007
Not only does the fully addressable DALI lighting-control system in the CatB fit-out of Allen & Overy’s new London headquarters provide a variety of options for the lighting itself, but it also holds on fan coils in response to presence detection and turns them off when lights go out.

Weeks of time on site has been avoided by building a series of plant rooms for two HBOS sites in Yorkshire in the factory of Armstrong Integrated Systems. |
HBOS banks on the value of off-site construction

Cost saving go on and on with building-systems integration
Published: May 2007
Being involved at an early stage in the Ideapark indoor commercial city near Tampere in Finland enabled TAC to achieve considerable cost savings by fully integrating the building-management and security systems.

Installation and running cost savings are both being achieved in this prestigious office building using an Ex-Or lighting-control system. |
Making lighter work of lighting
Published: May 2007
The need to install light switches in open-plan areas of a 3-storey office building at Burgess Hill has been eliminated by an Ex-Or lighting-control system which switches lights on and off in response to signals from presence detectors that respond to the smallest movements made by occupants; lights are also dimmed as required. The latest Building Regulations stipulate that light switches should be no further than 6 m away from the workstations of occupants.

The importance of understanding where a client sees value — Nick Cullen |
Perspectives on value engineering

Ensuring that value engineering genuinely delivers value rather than providing the wrong solution for the price we first thought of — Andy Green |
Best-value optioneering
Published: November 2005
When capital cost exceeds the available budget it is time to practise best-value optioneering — namely, investing in the right solution, not in just doing the project really well. ANDY GREEN explains.
