KATHRYN BOURKE and MIKE CLIFT discuss whole-life costing against the background of pressure from the Government for public-sector procurement to be based on this philosphy.
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.

Finding and recruiting the right staff is a problem in any industry — and one that particularly besets the building-services industry with its skills shortages and skills gaps. Ultimately, of course, the long-term solution is to attract more people into the industry and to develop training programmes that are in keeping with the needs of both employers and their staff.
In our personal life, rather than our working life, few people buy anything on the basis of lowest price. CIBSE’s new president Donald Leeper neatly encapsulates the issue in his presidential address when he asserts that few of us use lowest price to decide which garage will service our car, let alone which surgeon will operate on our children.
