Crowberry Consulting® Ltd Energy Review™ App allows the user to input the devices that consume power on their sites and rank these into high, medium, low significant energy uses. This information can support the energy review process as part of working towards an Energy Management System - EnMS such as the ISO 50001:2011 standard. The user can export a downloadable report which highlights in table format the devices on site, yearly KW hour consumption and input their own devices or select from drop down menus.
