What is the 'New Normal' for Facilities Managers? A very difficult question to answer with the future uncertain and the Government doing more U-turns than a learner driver. This is mainly due to the conflict between Health, Economics and Well-being but leadership and a strategy is sorely lacking. How do we return to work safely? And what will that...

Until the early 1980s, energy audits were defined as addressing where energy was used and what used it, whereas an energy survey was about where energy was being wasted and what could be done about it. The terms " energy audit " and " energy survey " were then used interchangeably, leading to confusion and misunderstanding about their specification...
