Qualitative study exploring interview data from 2 UK projects: ‘Carbon, Comfort and Control’ and ‘Conditioning Demand’; with regard to householder low carbon technologies interactions. The study was conducted by researchers at the University of Exeter who reviewed interview transcripts from a total of 18 households from across the 2 projects. The 9 household interviews for the ‘Carbon, Comfort and Control’ project took place between 2010-2011 in Merthyr Tydfil (6 households) and London (3 households). For the ‘Conditioning Demand’ project 9 in-depth seasonal household interviews were conducted in rural Devon between November 2011 and August 2012. ‘Carbon Control and Comfort’ concerned comfort and practice and was associated with the capabilities of low carbon technologies as objects; while ‘Conditioning Demand’ was concerned the experiences of elderly population and was associated with the meanings of ‘home’ and the domestication of low carbon technologies.
