Smart fire prevention

01 October, 2018

Whether accidental or intentional, fires damage more than just the structure of a building. They can wipe out millions of pounds worth of stock, destroy homes and the treasured possessions within them, damage hardearned reputations, pollute the surrounding environment and, in the most serious of cases, cost lives.

Has sampling had its day?

01 October, 2018

It may go against the grain, but I believe sole reliance on sampling as diagnostic practice is outmoded. The reason for this view is that these days there are more innovative and comprehensive ways to pick up the problems that lead to corrosion, allowing building managers to have better control of their water systems and quickly react to changes in condition, before bigger problems take hold.

Trimming the waste

01 October, 2018

Today’s HVAC system components are highlyefficient, but the key to overall system efficiency lies in designing specifically to exploit the part-load conditions under which the equipment will operate throughout its lifetime.

Find the best fit

06 February, 2018

When it comes to great building design, space for piped services is usually not even on the list of priority areas. Yet tight space for services can lead to challenges when it comes to operation and maintenance. Paul Wightman considers how to achieve more with less space.
