“…This result is comparable to Collins et al [16] stating that the reduction in CO2 emissions is expected by 2080 and heating loads remain dominant until 2080. The overall floor area of the case study is over 3756 m and as the building exceeds the SAP requirements of DER, solar panels are used to meet regulations (the impact of PV panels are not included in the simulation results).…”

Abstract:The likely increasing temperature predicted by UK Climate Impacts Program (UKCIP) underlines the risk of overheating and potential increase in cooling loads in most of UK dwellings. This could also increase the possibility of failure in building performance evaluation methods and add even more uncertainty to the decision-making process in a low-carbon building design process. This paper uses a 55-unit residential unit project in Cardiff, UK as a case study to evaluate the potential of thermal simulations to identify risk in the early design stage. Overheating, increase in energy loads, carbon emissions, and thermal bridges are considered as potential risks in this study. DesignBuilder (DesignBuilder Software Ltd., Stroud, UK) was the dynamic thermal simulation software used in this research. Simulations compare results in the present, 2050, and 2080 time slices and quantifies the overall cooling and heating loads required to keep the operative temperature within the comfort zone. Overall carbon emissions are also calculated and a considerable reduction in the future is predicted. Further analysis was taken by THERM (Lawrence Berkeley National Laboratory, Berkeley, CA, USA) and Psi THERM (Passivate, London, UK) to evaluate the thermal bridge risk in most common junctions of the case study and the results reveal the potential of thermal assessment methods to improve design details before the start of construction stage.

“…A large number of UK dwellings have no mechanical cooling systems [13]. Consequently, temperature increases will increase occupants' vulnerability to overheating [16]. Furthermore, there is a potential risk of heat loss through poor design detailing, which is widely neglected.…”

“…Flats that only have a limited window area would also struggle to achieve the higher ventilation rates required. The effectiveness of ventilation in reducing vulnerability to overheating indicates that unless policy is brought into control it, Britain could turn to air-conditioning as a solution (Collins, Natarajan, & Levermore, 2010).…”

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.

“…Natural ventilation rates for R buildings built after 1996 meet legislative requirements [58][59] [60][61] and the ventilation rates for older buildings are taken from [17]; for NR buildings, infiltration rates span from 0.5 to 1.0 ACH [45]. Average heat gain from lighting for R buildings is 0.9 W/m 2 (calculated from [15] and in accordance to [45] [45]. Average heat gains of occupants of R buildings range from 0.5 to 1.6 W/m 2 (calculated based on the number of persons per household [56] and the metabolic heat gain from occupants); for NR buildings, these range from 1.39 to 3.31 W/m 2 as calculated from the occupancy of warehouses, offices and retail [45].…”

(150 -200 words)Knowledge regarding the characteristics of national building stocks is fundamental to understanding how the energy performance of the building stock can be improved. To facilitate large diversity and a number of buildings for such analyses, this paper presents a methodology by which national building stocks may be aggregated through archetype buildings. The methodology has been implemented and verified in four EU countries in regions with different climates, namely France, Germany, Spain and the UK. These countries account for about half of the final energy consumption of the EU-28 buildings. The analysis includes the residential and non-residential sectors (residential sector only for Germany). The number of archetypes per country has been defined according to different categories of building type, construction year, climate region and the main fuel source for heating purposes. The accuracy of the description is validated by simulating energy demand using the ECCABS Building Stock Model, and comparing the final energy demand modelled with corresponding statistical data. The total final energy demand calculated for these countries differs from available statistics by between -6% and +2 %, which is considered satisfactory. The proposed description of the building stock is being used as a basis for analyzing the potential for and cost of energy conservation measures.
