New guidance for designers on bridging energy performance gap
So-called “low energy buildings” are increasingly being found to use more energy than their designers thought they would, with the performance of low energy designs often little better, and sometimes worse, than that of an older building they have replaced, or supplemented. This difference between expected and realised energy performance has come to be known as the “performance gap”. To help address this problem, the Chartered Institution of Building Services Engineers (CIBSE) has just issued new guidance on how to address operational energy use at the design stage. ‘TM54: Evaluating operational energy performance of buildings at the design stage’ is now available from the online CIBSE Knowledge Portal.

Niels Diffrient redefined what we know about ergonomics and office furniture
by Mark Eltringham • Comment, Furniture, Workplace design
Niels Diffrient, who passed away over the weekend at the age of 84, did more than any other designer to further the principles of ergonomic design as we now understand them. He is perhaps best known for his work over the last two decades on seating for Humanscale, including the groundbreaking and truly iconic Freedom chair, but his interest in function and comfort predated that by some time. As far back as the 1950s, Diffrient was one of the first people to x-ray a human spine while its owner was sitting and moving in a chair. He discovered that people will generally adapt to whatever they are sitting on without adjusting the seat. To Diffrient this suggested that the chair should be designed to adapt to the person rather than the other way round.
