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

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.

Central Park
Integration in action — the integration of a wide range of building-management functions at Central Park in Dublin is conservatively estimated to have saved 40% over a comparable multi-system solution.

Counting the cost savings

DEREK DUFFILL describes a cost analysis that shows how integrated building controls slashes both capital and running costs.

On average, energy accounts for an astounding 81% of the total life cycle of a filter system.

The value of energy-efficient filters

The energy consumption associated with an air filter can be 10 times its initial costs. COLIN HITCHdiscusses the implications.

fire station
It is estimated that the very long-life — about 19 years — of Chalmor Endurance lighting fittings will save over £20 000 on maintenance costs alone for this installation at the Fire Service College.

Re-assessing the true cost of lighting

Life-cycle costing is an important element in value-engineering exercises that seek to minimise whole-life costs. STEVEN HENRY suggests that life-cycle-costing exercises for lighting are becoming increasingly complex.

Mike Nankivell
Value engineering is intrinsic to the aims of the Energy Technologies List — Mike Nankivell.

Perpsectives on value engineering

MIKE NANKIVELL has doubts about some perceptions of value engineering — and suggests that products on the Carbon Trust’s Energy Technologies List offer the route to value.

4000 fan-coil units for Trox’s largest order to date were made and delivered over a period of 14 weeks. Full-scale testing of the units with associated plenum boxes, flexible ducting and grilles and diffusers enabled the performance to be guaranteed.

Delivering value engineering for fan-coil units

TERRY FARTHING explains how applying a system approach to designing and selecting fan-coil units and their associated equipment automatically leads to delivering value engineering.

test rig
Visitors to exhibitions may have seen this rig that Belimo uses to demonstrate how pressure-independent characterised control valves (bottom) maintain a constant water flow against differential pressures from 30 to 350 kPa compared with changing flow through simple CCVs (top two valves).

Opportunities for value engineering come in little orange boxes

Those distinctive orange Belimo direct-coupled actuators that abound in so many building-services installations and characterised control valves offer the potential for value-engineering opportunities.
