Multi service chilled beams can accelerate installation times, save energy and reduce maintenance, thereby dramatically cutting the whole life cost of an air conditioning system. GUY HUTCHINS explains.

JOHN LANGMAID puts the concept of whole-life costing into context against other evaluation processes that need to be undertaken during the design phase of a project.

Good energy-management practice not only reduces energy spend but also delivers buildings that are more productive to work in. IAN BUDD explains.

Energy savings of more than £3000 a year are being achieved following the replacement of five shell-and-tube calorifiers at Stafford General Hospital with Spirax EasiHeat engineered systems. The work has improved the supply of hot water to the main kitchen, and further savings are expected as more calorifiers are replaced in the future.

Air conditioning to provide both heating and cooling for the new premises of the Weather Shop In Eastbourne is being provided with 30% lower power consumption than traditional system using heat-pump systems with inverter drives. They also use use the ozone-friendly refrigerant R410A.

Baxi Group has outlined its commitment to launching a product based on micro CHP (combined heat and power) within the next three years.

A new guide to ‘Achieving whole life value in infrastructure and buildings’ could play a key role in helping the construction industry answer the challenge laid down in the National Audit Office’s report on ‘Improving public services through better construction’, published in March.

The economic and effective operation of showers can be achieved using an automatic flow limiter from Arrow Valves. These devices are designed to be fitted to a standard shower hose or head to save water and energy.

Sophisticated lighting technology for multi-service chilled beams installed throughout BT’s new Internet Protocol Management Centre building at Adastral Park, Martlesham, was designed and made by Cooper Lighting & Security. This is believed to be the first time that such sophisticated lighting technology has been built into chilled beams.
