Work is under way for a NABERS Energy rating tool for Data Centre. This will allow data centres in Australian to be rated as to their energy efficiency in the same way other buildings are. William Ehmcke and Graeme Philipson talked about the work to develop this rating tool at Data Centre GreenTech Melbourne 2010. This is not an easy task. There will then be training and guidance needed on how to comply. Currently there are some general books, such as Compliance for Green IT: Pocket Guide (Alan Calder, 2009).
