COLLAGE
With construction projects continually becoming more complex, how can they be validated ready for handover? MIKE WATSON has a solution.

The president of the Chartered Institution of Building Services Engineers, DONALD LEEPER, and its president–elect, DAVID HUGHES, are so enthusiastic about the benefits of CIBSE membership that they want more people to enjoy them and bring their expertise to the cause of better serviced buildings and addressing the environmental issues associated with buildings.
WEB
Recent legislation means that sacrificing energy efficiency to cut costs is no longer an option in building projects. In many cases, however, money can be saved without sacrifice by using an efficient and effective building-management system (BMS). ALAN ASHMORE explains.
PHE
Modulating boilers and high efficiency heat exchangers have altered the face of commercial heating and hot water installations, says PAUL SANDS
fig 1
Domestic hot water stored at 60°C or more and condensing water heaters (where the return temperature has to be below about 55°C) might seem a paradox. So how can condensing water heaters be included in the Government’s Energy Technology List. PAUL MARSDON explains.

Behind all those SEDBUCK A and B ratings and seasonal-efficiency figures for boilers is a comprehensive programme of performance testing. DR ARNOLD TEEKARAM explains how it all works.
Bob Walsh
Cast-iron boilers have a big future says BOB WALSH. Investment in the latest technology has ensured that the cast-iron boilers available today are more than up to the job required of them.

The role of micro-generation in the UK’s future energy strategy is to be examined by the Energy Saving Trust.
New homes are emitting 6000 t more carbon dioxide a year than they should be by not complying with minimum standards for air tightness, according to a report by the Energy Saving Trust. That figure is estimated to add £650 000 to heating bills a year.
wool insulation
Using wool from hill breeds of sheep with coarse wools to produce thermal insulation for buildings has won a prestigious ward for a company in Cumbria. Second Nature of Penrith makes high-quality insulation from this wool under the trade name Thermafleece. As an environmentally preferable alternative to conventional insulation products, it has aroused much interest, particularly in rural areas where renewable products such as wool are a vital part of a sheep farmer’s livelihood.
The UK market for solar photo-voltaics has fallen well behind other countries, according to figures from the International Energy Agency.
