Developing a meta-model for early-stage overheating risk assessment for new apartments in London

Predicting climate change and occupants’ behaviour impact on thermal-energy performance of global south housing: Case study in Brazil

“…In addition, decreasing the ventilation availability throughout the day was able to promote greater resilience for the case study, that is, less exposure to NV can guarantee greater resilience to climate change. Our results divert from the findings of Botti et al 72 , who identified NV as the most influential design variable for mitigating the risk of overheating. As expected, more time within the building, more discomfort hours would be registered, and the overheating risk would rise.…”

“…The green envelope (roof and wall) and the Trombe wall promoted the highest energy performance for all locations. Botti et al 72 evaluated the overheating risk for naturally ventilated apartments in London – UK. The simulation results indicated the window opening for NV as the strongest design variable to prevent overheating risk.…”

From Urban Microclimate to Indoor Overheating: Analysis of Residential Typologies During Typical Climate Series and Extreme Warm Summer

“…In relation to the number of orientations in a dwelling (related to the potential of cross-ventilation) it is the factor which presented the highest differences within %IOH (-9.7% of IOH in dwellings with more than one orientation compared to dwellings with only one orientation). Other studies also found ventilation as a key factor which reduces overheating: one verified that natural cross-ventilation influence in meeting CIBSE TM-59 criteria [30]; another research that evaluated natural ventilation as a system to reduce overheating risk in dwellings in the North of Spain, concluded that the typology with better temperatures was the one that had double orientation which allowed for cross-ventilation (on average, 1 • C less than the rest of the dwellings) [29]. However, it must be considered that, despite being a key measure to control overheating, natural ventilation in cities has limitations like pollution, noise….…”

“…In addition to the influence of UHI, indoor overheating is mostly conditioned by the building characteristics of the dwellings. There are different studies that analyse the influence of different building parameters in dwellings' indoor overheating all over the world in different climates: research in tropical climate analyse overheating risk depending on the building typology, roof exposure to solar gains and material properties [26]; study in Australia [27] and in UK [28] assess the overheating depending on the location in height (floor level) and the main orientation of the dwellings; case study in Spain assess which is the best natural ventilation and shading strategies to mitigate overheating issues [29]; other research in UK present the analysis of the orientation, fenestration size and natural ventilation in relation to indoor overheating [30]; and previous study in the same city of this research that quantify the influence of floor level, orientation, built period, window area and solar shading system on indoor overheating hours through monitoring data [31]. Besides, the behaviour of occupants is also relevant and influence indoor overheating, e.g.…”

Facing Climate Change in a Temperate European City: Urban-Scale Diagnosis of Indoor Overheating and Adaptation Strategies for Residential Buildings

“…Nowadays, in temperate Europe, the most common strategies for retrofitting building thermal envelopes include replacing windows with more energy-efficient ones and adding thermal insulation to façades, roofs and floors [25], with the main goal of reducing heating energy demand and consumption while maintaining adequate indoor environmental conditions during the winter. However, it is necessary to assess buildings' performance during summer by analysing which building parameters specifically influence overheating (like location in the building (floor level) [26][27][28][29], orientation of the main façade, area of windows [30,31], ventilation [32,33], shading systems [31,34], envelopes [35] and occupants' behaviour [12,36]) and to advance the research on passive strategies for renovating existing buildings and constructing new ones, focusing on reducing indoor overheating in summer to minimize the AC necessity to face high outdoor temperatures.…”
