This paper uses an interview study in Doha, the capital city of Qatar, to consider the role of qualitative methods in identifying how human relationships with air-conditioning are influenced. Drawing on discussions with three groups of comparatively affluent residents who spent significant amounts of time in air-conditioned spaces, it makes four points to researchers hoping to encourage less energy demanding lifestyles. The first is that ‘comfort is only one aspect’ when a premature focus on comfort obscures other potentially important analytical concerns. The second is that ‘air-conditioning changes cultures’ when valuable insights may be gleaned from what people say about how it creates, rather than responds to, local preferences and expectations. The third is that ‘comparison can be instructive’ when different groups may feel themselves to possess very different relationships with air-conditioning. The fourth is that ‘discussion can disappear’ when those hoping to influence these relationships may benefit from understanding when and how ‘conditioning conversations’ currently occur and how they could be part of processes of positive local change. After substantiating these points, wider conclusions are drawn about the promotion of less energy consumptive ways of adapting to a warming world and the value of this approach to the cultural geography of air-conditioning. research

Rapidly developing economies of countries in hot climates face the risk of a significant increase in CO 2 emissions. This study developed strategies for low energy cooling and ventilation for Indian residences (LECaVIR). Ventilation and cooling techniques were developed and tested for India’s four climatic zones. The analysis shows that natural ventilation is possible in typical residential buildings for about 20–40% of the year. Using an enhanced natural ventilation mode with appropriately sized openable windows and controls, the total number of hours for which natural ventilation is able to offer satisfactory conditions for occupants can be extended by a further 13 percentage points, leading to a potential reduction of 46% in the mechanical cooling hours for residences. Dynamic thermal simulation models, coupled with control software, were used to test the most promising natural ventilation strategies as part of a mixed-mode approach to ensure year-round comfort at minimal energy cost. The simulation shows that energy savings of up to 55% are possible.

Policies, codes, standards and voluntary ‘green’ assessments have exacerbated cooling demand in New Zealand’s commercial buildings. Building codes allow designs to use single glazing on the facade, voluntary ‘green’ criteria are not higher than the legal minimum in the code and inexpensive energy for commercial buildings all contribute to an increasing use of air-conditioning. Legal standards for the energy efficiency of the building envelope of commercial buildings have not significantly changed in over a quarter of a century and, over much of the same time, the cost of electricity (the predominant form of energy in New Zealand used to heat and cool buildings) has decreased for commercial buildings. These factors have led to an increased dependency on air-conditioning in commercial buildings. This increase in energy demand is unnecessary and can be reduced through policies, codes, and standards that reduce solar gain and use mixed-mode ventilation. The reduction in air-conditioning demand will improve energy security and reduce greenhouse gas emissions. a practical
