The document analyzes the carbon footprint of residential buildings at the University of Portsmouth and identifies ways to reduce it. Electricity and gas consumption data from 2008-2011 was used to calculate carbon emissions and compare building efficiency to industry standards. Energy audits and analyses of energy use compared to temperature found energy consumption highly correlated with weather. Margaret Rule and Trafalgar Halls used significantly more electricity than standards, while only Harry Law Hall met standards. Occupant behavior and improving insulation/heating systems could reduce dependence on weather and carbon emissions.
