“…If the average temperature were to rise more, to 2.48C, for example, the histograms would shift 18C higher, with a corresponding increase in the number of homes at risk and may require additional strategies such as mechanical ventilation for adequate mitigation. This is consistent with the findings of other studies that suggest that adaptation of the housing stock over the coming years will be necessary if the adverse effects of overheating are to be avoided in future (Gupta & Gregg, 2012;Porritt et al, 2011).…”

“…However, to date, research into overheating in the domestic sector has focused on a small number of dwellings (Hacker, Connell, & Belcher, 2005;Orme, Palmer, & Irving, 2003) One study (Porritt et al, 2011) showed that temperatures in the living rooms of typical Victorian terraces could be maintained below the CIBSE overheating thresholds in 2080 (with a Medium -High Emissions scenario) with a combination of interventions such as exterior shutters and ventilation strategies. A similar modelling study (Gupta & Gregg, 2012) investigated the potential for adaptation of several typical English dwellings, but found that no combination of measures was entirely able to eliminate overheating risk into the 2080s. Both of these studies were limited to a small number of dwellings, and do not make comments about the vulnerability of the housing stock as a whole.…”

The UK is predicted to experience warmer summers in the future, but the domestic building stock in England was not designed to cope with this change. The Standard Assessment Procedure (SAP) 2009 is used to assess the current state of the English building stock in terms of its vulnerability to overheating. The English Housing Survey 2009 provided data for 16 150 dwellings which are weighted to represent the housing stock. SAP predicts 82% of dwellings are currently at 'slight' risk of overheating and 41% at medium to high risk. If summer temperatures become 1.48 8 8 8 8C warmer, then 99% of properties are predicted to have a medium to high risk of overheating. Several potential adaptations to the housing stock were considered to reduce overheating. Although ventilation strategies had the largest positive effect, the use of solar shading and shutters which allow secure ventilation could reduce vulnerability to overheating in the current climate. In a warmer climate, although some dwellings would still be at slight risk, the results suggest that solar shading strategies could reduce the percentage of those at medium to high risk to 6%. Future energy efficiency programmes will need to include adaptation measures to prevent overheating.Keywords: adaptation, building stock, climate change, housing, overheating, ventilation, vulnerability Il est prévu que le Royaume-Uni connaisse à l'avenir des étés plus chauds, mais le parc bâ ti résidentiel en Angleterre n'a pas été conçu pour faire face à ce changement. La Procédure d'Evaluation Normalisée (SAP) 2009 est utilisée pour évaluer l'état actuel du parc bâ ti anglais quant à sa vulnérabilité à la surchauffe. L'Enquête 2009 sur le Logement en Angleterre a fourni des données concernant 16 150 logements qui sont pondérés de façon à représenter le parc de logements. La procédure SAP prévoit que 82 % des habitations courent actuellement un risque « léger » de surchauffe et que 41 % courent un risque moyen à élevé. Si les températures estivales devenaient plus chaudes de 1,4 8C, la prévision est que 99 % des biens immobiliers courraient alors un risque de surchauffe moyen à élevé. Plusieurs adaptations possibles du parc de logements ont été envisagées pour réduire la surchauffe. Bien que les stratégies d'aération aient eu l'effet positif le plus important, l'utilisation de dispositifs d'occultation solaire et de volets qui permettent une aération sécurisée pourrait réduire la vulnérabilité à la surchauffe dans le climat actuel. Dans un climat plus chaud, bien que certains logements courraient encore un léger risque, les résultats suggèrent que les stratégies d'occultation solaire pourraient réduire à 6 % le pourcentage de ceux présentant un risque moyen à élevé. Les futurs programmes d'efficacité énergétique devront inclure des mesures d'adaptation destinées à prévenir la surchauffe.

“…Gupta and Gregg (2012) cite the Passiv-on project which found that the high levels of insulation is Passive House buildings in southern Europe worked to keep the building cool during warm weather. However, McLeod et al…”

“…McLeod et al (2013) does however point out that Passive House dwellings may offer marginally more protection from overheating than other highly insulated options (Findings for the 2050s heavy weight passive house greater than 25°C for 6.6% of the year whereas a heavy weight 'well insulated' building greater than 25°C for 8.2% of the year). The core reasons for these differences are unclear, although Gupta and Gregg (2012) when considering a range of 'typical' dwelling types in Oxford found insulation position to be of importance. As such insulation may be a 'double edged sword' (Hacker, Holmes, Belcher & Davies 2005) with increased insulation reducing winter heat loss but increasing overheating risk especially in air tight buildings where it is difficult to dissipate internally generated gains.…”

“…A number of authors have explored potential solutions to overheating in domestic buildings (for example see Gupta & Gregg, 2012, Porritt, Cropper, Shao & Goodier, 2012, van Hoff, Blocken, Henson & Timmermans, 2015. These studies found that adaptation measures such as shutters and fixed shading, reductions in solar/fabric gains, increased surface albedo and the use of thermal mass may help reduce future overheating, although the magnitude of the influence of thermal mass has been questioned (Kendrick, Odgen, Wang & Baiche 2012).…”
