The value of intelligence in buildings — Allan Kell.

Investing in building intelligence — time to make the case for intelligence in buildings

The concept of intelligent buildings has been around nearly twice as long as green buildings. ALAN KELL asks how intelligent buildings can be made as popular as green buildings.

Holistic approach to integration delivers big business benefits

Making a proper business case is the key to progressing with integrated building automation, says JEROEN MULDER . The benefits are improved productivity and reduced costs.

Total building management

An asset-management suite from AMX includes building asset management and room-scheduling packages.

BUILDINGS
Among the benefits of intelligent building systems are making maintenance intuitive, so that it can be planned and scheduled — rather than considered only when the need arises.

Facilities management gets smart

With the rising costs of utilities and increasingly stringent Government regulations on energy, facilities managers need to overcome increasing challenges to ensure their buildings are managed efficiently and cost effectively. RICHARD HIPKISS explains how an intelligent building system can help achieve these goals.

Realising the potential of intelligent buildings

RAJESH SINHA explains how the IP network that is ubiquitous in new buildings provides the key to intelligent buildings.

school
Central control for buildings on a 300 acre school and community-centre site in Glasgow can be achieved from this touch screen that is part of a Schneider Electric T-BIS system.

Adding intelligence to a Glasgow school

One of the first schools to benefit from an intelligent system to integrate its services is the newly built St Benedict’s primary school and community centre in Glasgow. It uses Schneider Electric’s T-BIS system.

CIBSE membership is for everyone

The very many people who play important roles in the building-services industry and are not members of the Chartered Institution of Building Services Engineers now have the opportunity to join CIBSE and enjoy numerous opportunities to help them perform their jobs better and develop professionally.

The benefits of being a CIBSE member are for everyone

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
The use of web technology provides a user interface that is crucial to achieving the full potential of a building-management system.

Energy efficiency issues move to centre stafe

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.

Validation and handover management — adding value to projects

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

Bob Walsh
Bob Walsh explains that new designs of cast-iron heat exchangers are smaller, lighter, use fewer sections and can achieve 50% more output than previous designs.

Re-inventing the role of cast iron

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.

Efficient hot water and space heating come on a plate

Modulating boilers and high efficiency heat exchangers have altered the face of commercial heating and hot water installations, says PAUL SANDS

wood boiler
Carbon neutral — modern wood-burning boilers such as Hoval’s STC range can achieve combustion efficiencies of up to 86%.

Achieving carbon neutrality

In the long term, any real policy of sustainability needs to include a move to fuels that do not deplete the world’s irreplaceable reserve of fossil fuels. IAN DAGLEY considers the benefits of wood as a carbon-neutral fuel.

High-efficiency condensing water heaters — paradox or paradigm?

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.

pub
Air cleaners, such as this model from Honeywell, are being presented by the Air Cleaner Manufacturers Association to the Government as the key to permitting smoking in public places without inconvenience to non-smokers.

ACMA promotes air cleaners as answer to smoking issues

Support for the Government’s efforts to reduce smoking has been declared by the Air Cleaner Manufacturers Association, which also says that it does not believe a total smoking ban is workable. In a report submitted to the team responsible for smoking legislation at the Department of Health, ACMA points out that air cleaning provides a ‘middle way’ that provides comfort and clean air for both smokers and non-smokers.

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.

This new literature is described as indispensable for HVAC specialists serving the catering sector. It is a progression from the popular DW/171, which became the industry benchmark for kitchen ventilation systems after it was published in 1999.

It details all requirements for the design, installation and maintenance of kitchen ventilation systems and provides essential reference material for installers, specifiers and engineers.

There is also a standard for testing grease filters to reduce the risk of fire in commercial kitchens. Advice is included on the requirements for an interlock between the ventilation system and gas supply.
