Out with the old . . .

03 September, 2007
Refurbishing or upgrading existing heating plant provides the opportunity to deliver very significant increases in efficiency but there are a number of factors that need to be taken into account. Kevin Stones takes a look at the key considerations.
Norwich Union
Multi-service chilled beams remove the need for suspended ceilings, resulting in greater room height and more usable space. But their benefits in refurbishment projects don’t stop there, as Terry Farthing explains.
space
As part of the comprehensive of the 2700 m2 Apollo office building in Ruislip, Space Airconditioning supplied equipment for a Daikin VRVII heat-recovery heat-pump air-conditioning system to replace a chilled-water fan-coil system.

Heather Jefferson explains how best to exploit the energy-saving potential of CHP plant in existing buildings to produce power, heating — and cooling.
RS
The quality of lighting has been significantly improved and energy costs halved in the main distribution centre of RS Components at Corby by upgrading from high-pressure sodium to Venture Lighting’s pulse-start metal-halide lamps and Ventronic dimming system.
lamps
There are more benefits to be gained from controlling lighting than energy savings. The reductions in maintenance costs can be even more important. Mark Andrew explains how good lighting control can help slash maintenance costs.

The British Property Federation has backed Government plants to scrap the ‘Merton rule’, which requires a building to generate 10 to 20% of its energy through onsite renewables, on the basis that investing in inefficient onsite renewable-energy sources is simply not the best way to reduce carbon emissions.
Paradise
Balfour Kilpatrick has been awarded a £10 million contact to supply and install HVAC, electrical and plumbing services for the Paradise Project in Liverpool. This large £920 million retail-led mixed-use development comprising over 30 buildings, each with its own distinct character.

He is aiming to raise at least £2500 to help the charity in its fight against heart and circulatory disease, the UK’s biggest killer.
To encourage more students to study science and engineering, the Confederation of British Industry has proposed a bursary of £1000 a year per student. The suggestion has been made against the background of a decline over many years in the study of science, technology, engineering and mathematics (STEM) subjects. Its total cost is put at around £200 million a year.
