“…Casual gains have been shown to vary widely, even in identical properties. 12,13 In order to show the effects on energy demand on a national scale, taking the average or a typical level of casual gain is appropriate. In particular, peak or day-to-day loads are difficult to accurately establish for a single household.…”

This paper examines the likely effects on gas and electricity consumption and carbon emissions from heating and cooling systems in existing dwellings up to 2080, assuming a widespread uptake of cooling systems. This area of research is highly sensitive to the myriad of possible inputs and thus holds a wide range of predicted outcomes. However, general trends have been found, showing significant sensitivity to ventilation rate, U-values, occupant behaviour and location. Heating demand will still be dominant over cooling demand in UK dwellings by the 2080s, based on an UKCIP02 A1F1 weather scenario. A national worst case scenario for the 2050s, shows a 10 megatonne CO 2 emissions saving on present levels largely due to a 20% reduction in gas consumption. Practical applications: The balance of heating and cooling demand causes more modest changes in CO 2 than first anticipated. Despite first perceptions of future energy use in housing and climate change, heating appears to remain the major load rather than cooling, even into the 2080s. These predictions of future CO 2 emissions will be useful to those in the building industry planning appropriate proportionate climate adaptation and climate mitigation measures. Also, the prediction of changes to future energy demands from the housing sector will be of interest to energy providers considering future demands for heating and cooling and may feed into larger bottom-up energy models.

“…Space heating levels are considered to be constant regardless of the activity being carried out. However, in reality, heating is most effective if adjusted according to the activity being carried out: for example, a sedentary pastime requires a higher temperature for thermal comfort than more active pastimes (Hong et al 2006;Summerfield et al 2007). …”

“…5 This is not surprising as in the UK wintertime space heating energy demands are a major source of greenhouse gas emissions and under heating of homes is a significant health risk. Such studies include, for example, 1600 low income households (Oreszczyn et al, 2006), 427 homes in the CaRB study (Shipworth et al, 2009), 14 lowenergy homes monitored in Milton Keynes (Summerfield et al, 2007) and 25 households in Northern Ireland (Yohanis et al, 2010). The most extensive field survey (Hunt & Gidman, 1982) measured spot temperatures in each room of 100 homes in February and March 1978. 111,000 homes (ONS, 2010), Leicester is the UK's 15 th largest city and has households that cover a wide range of socio-economic categories, from affluent to the most disadvantaged.…”

[213 words]Internal summertime temperatures measured in 268 homes in the UK city of Leicester are reported. The hourly data was collected from living rooms and bedrooms during the summer of 2009, which was generally cool but with a short hot spell. Some household interviews were conducted. The sample of homes is statistically representative of the socio-technical characteristics of the city's housing stock. The data provides insight into the influence of house construction, energy system usage and occupant characteristics on the incidence of elevated temperatures and thermal discomfort.The warmest homes were amongst the 13% that were heated. Significantly more of these were occupied by those over 70 who are particularly vulnerable to high temperatures. The national heatwave plan might usefully caution against summertime heating.Temperatures in the 230 free-running homes were analysed using both static criteria and criteria associated with the BSEN15251 adaptive thermal comfort model. These indicated that that flats tended to be significantly warmer than other house types. Solid wall homes and detached houses tended to be significantly cooler.It is argued that adaptive criteria provide a valuable and credible framework for assessing internal temperatures in free-running UK homes. However, the temperatures in the Leicester homes were much lower than anticipated by the BSEN15251 model. Numerous possible reasons for this discrepancy are discussed.
