The role of contractors in sustainability — HVCA president Geoffrey Robinson.

Contracting in to sustainability

Sustainable designs do not have to be all about clever renewable technologies and blue-skies thinking. Traditional methods still have a lot to offer according to GEOFFREY ROBINSON

The recent opening of this energy-control bureau is helping to improve the energy performance of clients of GSH’s Energyplus service.

Contract energy management delivers carbon savings

Carbon emissions have been reduced by over 10 500 t by GSHs Energyplus contract-energy-management service over the last two years. The savings amount to over £1 million off the energy bills of clients.

Taking a lead in reducing carbon emissions — ideas from the winning entry of a competition to reduce carbon emissions from CIBSE’s two buildings at Balham by 60% are now being put into effect.

A hundred days of reducing carbon emissions

Samantha McDonough explains why CIBSE is embarking on a 100-day campaign to reduce carbon emissions and why it is important to get involved.

Training for future success

Because of the excellent air circulation associated with wire tray, cables can be classed as ‘clipped in free air’, enabling smaller, more efficient cables to be used.

The wired answer for power and data cabling

With welded steel-wire cable tray becoming increasingly popular for cable management, MATTHEW WAY dispels a few modern misconceptions.

Not only is the installation time for busbar virtually the same as for installing cable tray (before the installation of the cables!) but it also lends itself to compact installations because it has no ‘bending radius’.

Explaining the benefits of modern approaches to busbar trunking

Modern busbar trunking systems offer many benefits over cable, as JOHN CLARKE explains.

Power and data cabling systems for installing under raised floors include busbar.

Bringing data and power services to the workstation

Bringing data to office desks is every bit as important as bringing power — and is becoming more so. ALAN DURRANT explains the approaches available and how are they evolving?
