Sustainable energy? A feasibility study for Eastside, Birmingham, UK

摘要

Eastside, a 130 ha brownfield site located to the eastern side of Birmingham's city centre, is undergoing social, economic and environmental changes, driven mainly through public and private investment estimated to be worth £6 billion. The regeneration programme is well under way and it aims to turn a once deprived inner-city area into the regions first 'sustainability quarter'. Achieving a sustainable quarter, in terms of energy, will require reductions to be made in energy demands compared to typical practice, for example through more thermally efficient buildings and utilisation of low-energy technologies. In addition it will require these demands to be met through renewable technologies rather than fossil fuels. This paper presents estimates for the total energy demands from the various developments planned within Eastside assuming typical and good-practice scenarios. The paper then assesses the feasibility of introducing various renewable energy supply technologies and combined heat and power (CHP) technologies in order to meet these demands. Finally the paper presents a simplified costing scheme for assessing the potential of renewable technologies to secure energy supplies while limiting carbon emissions. The renewable technologies are compared directly, aiming at providing an independent viewpoint for decision makers when considering which technologies to adopt. While the study focuses on Eastside, the lessons learned from this study are vitally important for redevelopment programmes being undertaken elsewhere.
