AbstractOverheating risk is expected to rise in dwellings as heat waves continue increasing intensity and duration. This paper presents a simulation-based study on thermal resilience benchmark renovated nearly zero-energy dwelling during intense Belgium. Data analysis using simulations of the reference with without active cooling was used assess overheating risk. The indicated that resilient for over 91% occupied hours. Furthermore, existing building-level renovation strategies alone will not be sufficient mitigate require cooling. However, came an energy penalty 37.69 kWh/day monitored period, any potential benefits should factor excess use. presented findings lead recommendations future building practices identified needs further research.KEYWORDS: OverheatingnZEBindoor environmentactive coolingbuilding renovationenergy AcknowledgmentsThe European researchers were funded by SPW MK Engineering under BEWARE fellowships EU MSCA framework programme through contract no. 847587. authors would like gratefully acknowledge Walloon Region, MSCA, Project SurChauffe funding.

Assessing Overheating Risks in Moderately Insulated Irish Social Housing: Analysis of Building Energy Ratings and Indoor Temperature Profiles

Energies, Год журнала: 2025, Номер 18(6), С. 1381 - 1381

Опубликована: Март 11, 2025

As buildings become more energy-efficient in cold climates, the unintended consequence of increased overheating risk during warmer seasons necessitates attention. In this context, there is an absence research addressing assessment risks residential Ireland. This study assesses data from a sample 1100 social housing units Dublin, majority which have Building Energy Rating (BER) C, representing moderately insulated dwellings. Using indoor temperature and outdoor climate reports for 2022, evaluates based on both static adaptive criteria living room zone The methods used include Chartered Institution Services Engineers (CIBSE) Guide A Passivhaus Institute standard, while follow CIBSE TM59. findings reveal discrepancies assessments: overall, 4% surpass thresholds under A. contrast, 41% dwellings exceeded standard May to September 2022. Adaptive criteria, however, indicated minimal instances, at 0.4%. These results highlight how different methodologies influence conclusions. impact two-fold. First it further strengthens existing literature questions appropriateness methods. Secondly, shows that set minimal.

Multi-country multi-city study on heterogeneous impacts of urbanicity on heat-related mortality

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 11, 2025

Urbanicity might have complicated impacts on heat-related mortality, intertwined with national and regional context; however, the relevant evidence is limited. This multi-country study investigated complex roles of urbanicity considering spatial heterogeneity across different urban contexts. Through Multi-City multi-Country (MCC) research collaborative network, data mortality ambient temperature from 397 cities in 12 countries were collected, we examined heterogeneous associations between characteristics heat-mortality risk by region. Higher population density was associated increased North America Europe, while inverse association observed Latin America; not significant East Asia. Among environment factors, PM_2.5 concentrations, CO₂ emissions, heat island intensity generally contributed to a higher risk. Whereas greater greenness mitigated risk, particularly Europe. Our findings highlight vulnerability could provide scientific for establishing targeted health strategies against climate change.

The outdoor climate is expected to undergo significant and extreme changes. These changes may lead increased building requirements depending on their location. This critical, as human beings tend spend a large part of time inside buildings. Accordingly, it crucial take future conditions into account ensure an adequate indoor climate, simultaneously meeting the current drive for decarbonization built environment. One avenue opting thermally efficient products technologies with lower carbon footprint guarantee comfortable while minimizing energy consumption. study focuses Northeast region Brazil, specifically its nine states, given usage specific passive thermal strategies in new buildings that have high compensatory achieved through developing computational models housing unit multi-family building, commonly constructed several cities this region. model was employed analyze comfort, consumption, footprint.
