The aim is to achieve greater energy efficiency in buildings without high capital spend, through greater engagement with building users, and develop toolkits and consultancy methods that can be rolled out rapidly to large commercial and industrial buildings. Our approach uses innovative software and lightweight technical approaches that can be easily retrofitted into buildings or existing IT solutions. These leverage and exploit existing infrastructure such as CCTV, IT servers, time management systems, phone systems, building management systems to provide highly visual analysis of energy usage, engaging communications and user-centric ââ¬Ëconversational tools and controlsââ¬â¢ to help facilitate greater energy efficiency.
