Technical options for retrofitting the building stock. A case study from the United Kingdom

Abstract:

This paper presents a qualitative exploration of technical options for reducing the energy demand in buildings and a quantitative exercise on three specific neighbourhoods in Newcastle upon Tyne, UK. The aim is to arrive at an evaluation of the potential for energy reduction, taking into account the interactions between the dwelling stock and the energy supply systems. We first conceptualize the importance of planning and place, and then the Newcastle sustainability vision and the appropriate legislation and master plans that make it possible. One of the key components for this vision is the renewables and the micro-generation strategies. First, we propose energy refurbishing measures in building fabric, the cost-effectiveness and market penetration of each measure and finally the most appropriate measures for Newcastle; then measures for improving the air-tightness and ventilation, and a reengineering of heat supply systems. Finally, a complementary strategy for low-income households, those are not able to meet the UK Green Deal Policy requirements of eligibility.
