This document discusses three research projects - DUALL, Greenview, and PROCO2 - aimed at visualizing energy usage and reducing consumption through information and communication technologies. DUALL seeks to understand how ICT can reduce energy use in large public buildings. Greenview aims to design a smartphone app allowing building users to view energy usage across De Montfort University. PROCO2 aims to create a decision-making tool to help DMU reduce procurement-related emissions. The projects explore making energy data and impacts more transparent and engaging users through augmented reality applications.
