As global urbanization accelerates,super high-rise buildings increasingly face critical safety challenges due to mid-life vulnerabilities that can cause casualties and economic losses.This study examines two typical risk systems in super high-rise buildings—primary structure damage and building envelope detachment—to address urban risks and emerging safety management needs.Through a mixed-methods approach,we developed a theoretical framework based on"environmental pressure–building physical condition–management response"relationships.Using literature analysis and the Delphi method,we established two comprehensive risk indicator systems and analyzed their interaction mechanisms using fuzzy DEMATEL-AISM.Our findings reveal that root-level environmental pressures(e.g.,seismic activity,wind/snow loads)trigger structural disasters,while intermediate-level building physical conditions mediate these pressures and management responses,forming core disaster pathways.Management factors influence safety outcomes throughout a building’s lifecycle by operating across both root and result levels,with significant feedback loops in both risk systems.Based on these findings,we propose four integrated management strategies:root-level environmental pressure monitoring for early prevention;efficient identification of physical defects from surface damage;full-lifecycle risk management with specialized operations and maintenance;and collaborative diagnostics driven by loop factor assessment.This research bridges engineering perspectives and safety management,offering stakeholders—including building owners of super high-rise buildings,government authorities,and design professionals—practical approaches to enhance safety for millions of inhabitants while contributing a comprehensive theoretical framework for risk analysis. 展开更多

Buildings increase the urban surface roughness and reduce near-surface wind speeds due to the drag effect,which depends on the flow direction.In this study,a building drag parameterization scheme including the building anisotropy for all flow directions was developed through approximating buildings with elliptical columns to represent anisotropic frontal area index.The new scheme was coupled with the Weather Research and Forecasting(WRF)model to improve urban simulations in those including near-surface wind speeds.The conducted offline sensitivity tests with the developed scheme,using horizontal wind along different directions,show continuous transitions of drag coefficient and other variables depending on flow direction.The maximum difference of drag coefficient between the new and the original scheme reached 10%–20%of that from the original one.These monthly simulations of the WRF model with the new building drag scheme for Chengdu were conducted to validate the updated model against station observation and reanalysis data.Compared to the original scheme,the updated scheme reduces overestimation of 10-m wind speed by 0.1–0.2 m s−1(5%–15%of the original bias),overestimation of 2-m temperature by 0.1℃–0.4℃(20%–60%),and underestimation of 2-m relative humidity by 1%–3%(20%–60%).This is achieved by increasing the drag coefficient through an enhanced frontal area index and reducing wind speed.The diminished wind speed reduces sensible heat flux,enhances latent heat flux,and suppresses vertical motions,resulting in humidity accumulation and cooling in the lower atmosphere.These suggest that reasonable representation of the building anisotropy is important in researching urban climate. 展开更多

Against the backdrop of advancing the“dual carbon”goals and the growing urgency of building energy conservation needs,shading technology,as a key means to regulate the indoor light-thermal environment of buildings and reduce building energy consumption,is of great significance for improving the comprehensive performance of buildings.This paper systematically reviews the impacts of shading technologies on building performance,defining the research scope to cover four core dimensions:performance evaluation indicators of shading technologies,testing methods,energy-saving characteristics,and impacts on architectural design and aesthetics.Research shows that dynamic external shading and comprehensive external shading have significant energy-saving advantages,while internal shading and intermediate shading have wide adaptability.The energy-saving effect of various shading technologies is closely related to climate zone characteristics and component materials.This paper also points out the current deficiencies of shading technologies and looks forward to the future development direction of green low-carbon,intelligent and efficient.This review can provide theoretical support and practical reference for building energy-saving design,shading product research and development,and the formulation of relevant standards,helping the construction industry achieve green and low-carbon transformation. 展开更多

Amid global warming and urbanization,building energy systems face the dual challenge of balancing growth in energy demand with environmental sustainability and resistance to future climate change.This study proposes a predictive framework that integrates the effects of future climate change and urban microclimate into energy consumption prediction and energy system optimization for typical office buildings in Hangzhou,China.First,optimal general circulation models(GCMs)from CMIP6 are selected through a performance evaluation,and statistical downscaling is employed to generate future typical meteorological year(TMY)data.Next,the urban weather generator(UWG)is used to simulate urban heat island(UHI)effects.Empirical formulas are applied to calculate urban wind speeds,while DesignBuilder is used to model solar radiation and hourly energy consumption.These data are then used to optimize the building energy system.The results reveal that future climate change significantly increases cooling demand(28.9%-103.0%)and reduces heating demand(19.7%-52.6%),with urban microclimates further amplifying these trends.The energy system optimization demonstrates that the net present value(NPV)of future climate and urban microclimate scenarios is 5.1%-16.7%higher than that of historical climate scenarios.Additionally,future climate scenarios result in higher peak energy demand and thus necessitate larger system capacities to ensure reliability.While the initial required investment is higher,buildings optimized to account for global warming are more reliable and carry lower operational costs.We comprehensively quantify the effect of future urban microclimate on building energy systems,emphasizing its critical role in energy system planning and providing insights for addressing the challenges of climate change and urbanization. 展开更多

The stack effect in super high-rise buildings is mainly influenced by the temperature difference between the indoor and outdoor environments,wind pressure,building height,and the airtightness of building components.Consequently,the intensity and frequency of the stack effect are inherently impacted by regional and seasonal climate conditions.This study initially examines two critical meteorological elements-temperature and wind speed-that are closely related to the stack effect in high-rise buildings.Then the appropriate climate demarcation for evaluating the stack effect in high-rise buildings,which is based on the building climate demarcation in China is investigated,and the land area of China is divided into four climate regions for the purpose of stack effect assessment.Utilizing annual meteorological monitoring data from each region,the probability function models for temperature and wind speed are developed,and a joint probability distribution function for temperature and wind speed in each region is derived using a binary copula function.Finally,the probabilistic assessment of the stack effect under both pure and combined thermal pressures across different climatic zones is numerically investigated by employing a standardized high-rise building model.This research enables a refined assessment of the stack effect for high-rise building,and provides a useful reference to improve the design codes in future. 展开更多

Building occupants often have limited control over their environmental settings,which can lead to both dissatis-faction and inefficient energy use.This issue highlights the need for innovative solutions that not only improve environmental control but also actively involve occupants in the decision-making process.In response to these challenges,this study introduces an occupant-centric Digital Twin(DT)framework that presents environmental and building data to occupants for their informed decision-making.While the existing occupant-centric DTs were designed for facility managers as direct users,this study invites occupants as direct users of DTs and explores DT-based occupant-building interfaces.Leveraging the versatility of DTs,this study proposes three distinct user interface(UI)types,person-based,object-based,and recommendation-based controls,and investigates their im-pact in terms of user satisfaction,situation-dependent preferences,and data-sharing willingness.The test involved 120 participants and found that preferences for different UI types varied significantly depending on occupants’contexts.Furthermore,participants expressed a strong preference for having the ability to switch between or mix different control types based on their current needs and context.In terms of participants’attitudes towards data sharing,participants were more willing to share data when they understood the benefits and were assured of anonymity.These findings provide insights into how to transform DT systems into occupant-building interfaces that enhance personal comfort and energy efficiency through context-aware occupant engagement. 展开更多

A three-tower connected reinforced concrete(RC)frame building was selected as a prototype building and used to investigate resilience-based seismic design,aiming to provide a reference for multitower-connected buildings by using seismic isolation.First,a seismic resilience assessment strategy was recommended based on the characteristics of the case study.Specifically,the restoration cost index was recommended as the ratio of the total repair cost of multiple towers and connection parts with respect to the current replacement cost.In contrast,repair time and casualties were recommended as the longest repair time and the highest casualties of multiple towers due to their uncoupled functions.The influences of the critical design parameter of the isolation system(i.e.,yield ratio)on the resilient performance of the entire building was investigated.Both the repair cost and time of the building decreased at decreasing yield ratios,which were attributed to the notable control of the maximum absolute floor acceleration.Only the case study,which showed a yield ratio of 2%,achieved the highest resilience level,as regulated by the relevant Chinese code.Hence,a 2%yield ratio is recommended for the conceptual design of seismically isolated multitower-connected buildings to achieve good seismic resilience. 展开更多

The residential building sector significantly contributes to global carbon emissions,requiring innovative energy efficiency solutions.In the UK’s temperate climate,heating demand is a major driver of residential energy use.With one of the oldest housing stocks in Europe,the UK offers substantial opportunities for thermal perfor-mance improvements and energy savings.Windows,a significant source of heat loss,are a critical focus for efficiency improvements.Traditional approaches,like replacing windows with high-efficiency glazing,are often cost-prohibitive and impractical,especially for older and historical buildings.Despite extensive research on advanced glazing technologies,there is a gap in studies focused on the effectiveness of secondary glazing,par-ticularly when applied to existing double-glazed windows.This study aims to fill this research gap by exploring the effectiveness of secondary quad glazing,which involves adding a pane of glass or acrylic to the internal and external sides of existing double-glazed windows,creating additional air gaps that enhance insulation.This research integrates field testing and building energy simulations to evaluate the thermal performance and cost-effectiveness of secondary quad glazing.Field tests conducted in a mid-terrace residential building in Nottingham,UK,showed improvements in insulation,with secondary quad glazing reducing heat flux and maintaining higher internal surface temperatures compared to traditional double glazing.Thermal imaging and cumulative U-value measurements,which indicate the rate of heat transfer,confirmed these findings,indicating lower heat trans-fer rates(48.4%lower than traditional double glazing).Additionally,reduced condensation on the secondary quad glazing can help inhibit mold growth.Energy simulations further highlighted potential heating demand reductions of up to 18%during the coldest months and up to 25.7%during transitional months.The analysis indicated that secondary quad glazing in the test room led to annual energy savings of 91.5 kWh,at a fraction of the retrofitting cost of modern glazing options-nearly eight times cheaper than replacing windows with double glazing of a similar U-value and almost eleven times cheaper than installing new triple glazing.This study highlights the viability of secondary quad glazing as a practical and minimally invasive retrofit solution for enhancing energy efficiency in existing residential buildings.The ease of installation and cost-effectiveness of secondary quad glazing keep it simple,making it an accessible option for building retrofits,especially in the context of ongoing energy challenges and economic uncertainties. 展开更多

As important sources of new drugs,natural products(NPs)are conceptually biosynthesized from simple structural pioneers(i.e.building blocks).The traditional non-targeted purification strategy extensively suffers from the time-consuming and laborious bottlenecks.Fortunately,liquid chromatography–mass spectrometry/mass spectrometry(LC–MS/MS)-guided separations widely succeed in recent decades.However,it is still challenging for LC–MS/MS to precisely capture new NPs.Efficiently extracting information from the chaotic chemical composition and confident structural annotation are two primary technical barriers for pursuing the interesting structures,particularly those exhibiting trace distributions and high-level structural complexity.Here,to provide accurate guidance for the follow-up phytochemical purification,molecular defect filtering(MDF)and feature-based molecular networking(FBMN)[1]were incorporated to explore NPs and thereafter,bottom-up structural analysis was undertaken through identifying building blocks with full exciting energy ramp(FEER)-MS 3 matching.Sesquiterpene-chromone hybrids(SCHs)structurally configured by two building blocks such as units A(chromone)and B(sesquiterpene)[2]in agarwood were characterized as a proof-of-concept.Twenty-five SCHs were captured and identified.Thereof,seven new SCHs were purified with a LC–MS/MS-guided manner and annotated using nuclear magnetic resonance(NMR)spectroscopy to justify the proposed structures.Moreover,their cell-protective and anti-inflammatory activities were evaluated.Together,the incorporation of post-acquisition data processing strategies and FEER-MS 3 spectrum matchingassisted building blocks identification facilitated novel NPs exploration and purification. 展开更多

The cross-floor spread of fire smoke in a two-story building hinders personal evacuation and leads to casualties.To address this issue,sufficient wind pressure needs to be applied at the stair to prevent smoke from entering the upper space,and the critical velocity is an important parameter worthy of attention.By conducting a series of model experiments and numerical simulations in this study,the critical velocity below the ceiling screen at the stair is investigated,considering the factors of heat release rate(HRR),fire source location,ceiling screen depth and number of stairs.The results show that the critical velocity is proportional to one-third of the HRR,and the proportional coefficient decreases as the fire source is farther from the stair and the ceiling screen depth increases.The prediction models for the critical velocity under fire sources located in front and back of the stairs are proposed,respectively,and the proposed model is validated under three stairs.Additionally,the proposed prediction model is compared with the velocity value required by the relevant standard,and some dangerous situations are identified that require further strengthened ventilation.This study can provide theoretical guidance for ventilation design and emergency response in actual engineering with similar structures. 展开更多

Buildings constructed prior to the implementation of seismic design standards or those built based on lower standards are susceptible to earthquake risks,resulting in substantial loss of life and property during an imminent earthquake.Although conventional rapid visual screening(RVS)methods have been extensively developed,both nationally and in the literature,they have limitations in accurately determining the vulnerability of buildings.Additionally,RVS methods developed on the basis of a single algorithm have limitations.Therefore,this study extends the existing body of work by integrating multiple AI algorithms,including fuzzy logic,machine learning,and neural networks,in the context of building damage data from the 2015 Gorkha earthquake,overcoming the limitations of previous studies by introducing an automated AI-based RVS methodology that enhances accuracy,transparency,and adaptability.The newly developed RVS method demonstrates an accuracy rate of 45.89%for testing in the three-class classification,while also delivering promising results in the two-class classification,with an accuracy rate of 60%,surpassing both conventional RVS methods and the baseline accuracy rate. 展开更多

Precise analysis of the floor acceleration amplification(FAA)factor is crucial for accurately predicting the acceleration on acceleration-sensitive nonstructural components and estimating the seismic safety of nonstructural components.However,the existing literature on FAA did not analyze various influencing factors quantitatively.For solving this problem,one novel quantitative analyzing method of FAA considering various influencing factors in terms of structural type,structural height,site category,structural period,relative height and ground motion intensity based on instrumented buildings data from the Center for Engineering Strong Motion Data(CESMD)is proposed.The analysis results revealed that the site categories can significantly affect the FAA values of various types of structures,however,which has not been emphasized in previous studies.Correlation analysis reveals that the relative height is strongly correlated with the FAA,which is consistent with several seismic design codes.While,the parameters in terms of the site category,structural height and structural type also significantly correlated with the FAA.The results indicate that these three factors should be incorporated into the seismic design code.This study offers valuable insights and recommendations for the design of acceleration-sensitive nonstructural components in terms of FAA. 展开更多

Furniture and equipment modeled as rocking rigid bodies within buildings are vulnerable to overturning during earthquakes,and their responses are strongly influenced by floor-level seismic amplification.However,predicting their seismic behavior typically involves analyses of building structural responses and rocking-body dynamics,making conventional approaches computationally expensive.Existing methods also struggle to adequately capture the nonlinear interactions among seismic motion characteristics,structural amplification effects,and the geometric properties of rocking bodies.To address this issue,this study proposes a data-driven method for predicting the seismic response of in-building rocking rigid bodies using a deep neural network(DNN).Floor seismic responses were obtained from city-scale nonlinear time-history analyses and used to calculate corresponding rocking-body responses.A multidimensional database was then established,covering various ground-motion intensity measures,building heights,and rigid-body geometries.Based on this database,a DNN model was developed for rapid overturning prediction.Results show that the proposed model achieves high computational efficiency and an accuracy of 94.37%on the test set,outperforming conventional machine learning methods.Dimensionality reduction further decreases input features and training time while preserving strong predictive performance.The proposed approach provides an efficient and intelligent framework for seismic assessment and risk analysis of rocking components in buildings. 展开更多

This study investigates the problem of prioritizing rooftop renewable energy(RE)system configurations for a multi-family residential building in Mediterranean climate.The analysis focuses on fixed-tilt photovoltaics(PV),single-axis and dual-axis tracking PV,and small vertical-axis wind turbines(VAWT),each assessed with and without lithium-ion storage.A co-simulation framework is used,coupling EnergyPlus building-HVAC system simulation with PV and wind generation modeling and rule-based battery dispatch to evaluate hourly demand–supply interactions.Three decision criteria are considered for each alternative:total system cost,annual building electric energy demand reduction,and net avoided life-cycle emissions.Stakeholder preferences are elicited via Analytic Hierarchy Process(AHP),considering the building owner as the decision-maker.The design alternatives are then ranked with three multicriteria decision-making(MCDM)methods(TOPSIS,ARAS,and COPRAS)and a global rank is computed through an ensemble(Borda)aggregation.Results show that due to roof-area constraints,dense fixed-tilt PV system layouts are favored to achieve maximum annual generation(≈60.8 MWh per year),whereas tracking systems achieve higher specific yield but lower system capacity per roof because of increased need of spacing and maintenance corridors.Design alternatives that incorporate energy storage significantly raise self-consumption and demand reduction.Indeed,fixed PV with large storage can reach high annual coverage of building electric energy consumption,while the same PV without storage can reduce it by~43.7%.VAWT options contribute modestly to energy demand reduction given unfavorable urban wind conditions and their shorter lifetime.Under owner-centric weights that emphasize cost,the ensemble ranking prioritizes low-CAPEX PV solutions(dual-axis PV without storage,single-axis PV without storage,single-axis PV with small storage,and fixed-tilt PV).Instead,design alternatives encompassing large energy storage and small-wind alternatives occupy the lower ranks.The findings provide useful insights and a stakeholder-wise tool to select rooftop RE technologies on Mediterranean residential buildings,balancing economic feasibility with energy and environmental performance. 展开更多

Although the effectiveness of a tuned viscous mass damper(TVMD)as an inerter-based device for vibration control in civil structures has been thoroughly investigated,there is a lack of systematic research regarding the application of TVMDs for seismic response control of industrial buildings coupled with mechanical equipment.Therefore,this study proposes ungrounded and grounded TVMDs to effectively utilize the mass of the mechanical equipment and fully exploit the capabilities of the inerter element.An optimal design methodology is developed by pursuing the maximum effective damping ratio and seeking the most rational TVMD control scheme.Validation of TVMD control performance is conducted through time-history analysis based on 20 real seismic ground motions recommended by ATC-40,and by providing a barrel mixer industrial building as a real-life numerical example.The results show that both an ungrounded and grounded TVMD can effectively mitigate the seismic response of the primary structure.Compared to the traditional tuned mass damper(TMD),TVMDs can obtain improved control performance for a given equipment mass ratio.Moreover,an ungrounded TVMD and a TMD show similar working mechanisms that tend to release the displacement of equipment to keep their optimal state,whereas equipment displacement for a grounded TVMD should be strictly limited to provide sufficient anti-force. 展开更多

The urban heat island effect and extreme high temperatures pose significant challenges to the livability of cities,making it urgent to mitigate urban heat issues.However,uncertainty remains regarding the most effective cool-ing measures.The differences between single and combined measures have not been clearly defined,and there is limited research comparing their impacts on urban microclimates and energy consumption.Therefore,this study aims to explore the differences between single cooling measures and mixed cooling strategies from the perspectives of temperature,thermal comfort,and building energy consumption to provide a more holistic impact analysis of cooling strategies.Therefore,this study conducted a simulation on a typical street canyon in Melbourne,Australia,on December 20,2019.Four individual scenarios and six combined scenarios were established.Subse-quently,the environmental parameters and building energy consumption were simulated under various cooling scenarios.The results indicated that the combined cooling scenario with three measures achieved the highest comprehensive score,demonstrating the most favorable impact on the thermal environment and building energy consumption.We also found that the green scenario combined with high-reflectivity can reduce building energy consumption by 71.83 kWh within a day,yielding the best results.However,the combination of green infrastruc-ture,permeable surfaces,and misting proved to be the most effective in improving the environmental thermal comfort,with a maximum reduction of 1.86°C in the UTCI(universal thermal climate index).This study can provide guidance and recommendations for designers in the early stages of decision-making. 展开更多

Accurate building electricity load forecasting(BELF)can provide a regulatory basis for building energy management systems and promote the transition of buildings toward low-carbon and intelligent operation modes.However,building electricity load is influenced by historical loads,as well as outside environmental conditions such as humidity and temperature,which reduces the prediction accuracy of models.To tackle these challenges,this study presents a BELF model,which consists of a modal component grouping approach,grouped feature attention mechanism,and multi-scale residual depthwise convolution memory module.First,the modal component grouping method analyzes building electricity load in the time domain,frequency domain(via fast fourier transform,FFT),and complexity(via sample entropy,SE),and then performs clustering to achieve precise decomposition of load components with different fluctuation characteristics.Second,the grouped feature attention mechanism assigns suitable importance to various input features to emphasize key factors affecting prediction accuracy.Third,the multi-scale residual depthwise convolution memory module mitigates the impact of long and short-term load variations on BELF by employing residual blocks of depthwise convolution layers with different kernel sizes.Meanwhile,gated recurrent units are used to identify the time-dependent trends of building load.Experimental results on public buildings show that the proposed model outperforms existing models,achieving more than 2.4%improvement in MAPE prediction performance. 展开更多
