Architectural design of office buildings in vietnam’s coastal cities for reduced energy consumption

Office buildings are considered one among largest energy consumers compared with other categories due to day-time operation of lighting and office supplies. The used energy is critically higher in the air-conditioned buildings where HVAC system is enabled over course of the day and even the year. In major Vietnamese coastal cities blessed with Nature’s mild climate, the majority of local office buildings are of gathered-block typology that fails to consider the favourable aspects of climate condition. At first, this study aims to investigate the influences on indoor comfort and energy consumption of two key factors, i.e. outdoor climate and solar radiation, in major Vietnamese coastal cities based on bio-climatic analysis of 20-year historical meteorological data from 1981 to 2000. Then, the study suggests the optimal architectural design (Strategies of Climate Control) of office buildings in the considered towns to maximize climatic favours for reduction of energy use, particularly ones for HVAC. In this research, case study is the Danang Administrative Center building.

Impact of architectural design strategies on the indoor natural ventilation of public residential buildings in Singapore

The architectural design pattern of the public residential buildings developed by Housing and Development Board (HDB) of Singapore has evolved gradually throughout the past decades. However, the fact is that although the new generations of HDB blocks built in recent years are designed to be modernized, the usage of air-conditioning has been increasing in comparison with the old generations. This study aims to investigate the ventilation performance of HDB blocks built in different generations from a historical view. By conducting computational fluid dynamics (CFD) simulations on five typical blocks built in different generations, the area-weighted wind velocities in various rooms of the target units were obtained. The effects of design factors on wind velocity ratio (VR) in corresponding spaces were analyzed and compared. The results show that the old generations with parallel plan layouts generally facilitate cross-ventilation while the new generations with centralized plan layouts usually generate single-sided ventilation which is more sensitive to incoming wind direction. Meanwhile, the window-to-wall ratio and shading depth of the studied facades were validated to have positive and negative relations to the VRs respectively. Though the correlations are insignificant, they show significant disparities between the scenarios under different incoming winds.

Daylight Analysis in Terms of Building Direction and One-Way Roof

The location of the buildings in the residential area is very important in protecting or benefiting from sunlight. The dynamic structure of the sun, which constantly changes according to time and seasons, directly affects the building's architecture and urban formation. Ignoring the sun's use of the structures during the construction of the buildings can cause significant disturbances to the residents. Daylight strategies, which are also influenced by climate, depend on the availability of natural light, determined by the latitude of the building site and the instantaneous conditions around the building. High latitudes have different summer and winter conditions, with lower daylight levels in winter. At these latitudes, designers often aim to maximize daylight penetration in buildings. In the tropics, where daylight levels are high throughout the year, the design emphasis is often on preventing overheating by limiting the amount of sunlight entering the building. Daylight availability depends not only on latitude, but also on the orientation of a building, and each facade and material of the building requires a different design importance. Therefore, daylight and architectural design strategies are two inseparable phenomena. In this respect, examining traditional architecture and successful natural lighting designs in the past is very useful for understanding climate-balanced building design. For this purpose, determining the roof slope according to the sun angle in architectural structures by calculating according to the location provides efficiency in many issues from energy efficiency to human health.

Designing Clinical MRI for Enhanced Workflow and Value.

MRI is an expensive and traditionally time-intensive modality in imaging. With the paradigm shift toward value-based healthcare, radiology departments must examine the entire MRI process cycle to identify opportunities to optimize efficiency and enhance value for patients. Digital tools such as "frictionless scheduling" prioritize patient preference and convenience, thereby delivering patient-centered care. Recent advances in conventional and deep learning-based accelerated image reconstruction methods have reduced image acquisition time to such a degree that so-called nongradient time now constitutes a major percentage of total room time. For this reason, architectural design strategies that reconfigure patient preparation processes and decrease the turnaround time between scans can substantially impact overall throughput while also improving patient comfort and privacy. Real-time informatics tools that provide an enterprise-wide overview of MRI workflow and Picture Archiving and Communication System (PACS)-integrated instant messaging can complement these efforts by offering transparent, situational data and facilitating communication between radiology team members. Finally, long-term investment in training, recruiting, and retaining a highly skilled technologist workforce is essential for building a pipeline and team of technologists committed to excellence. Here, we highlight various opportunities for optimizing MRI workflow and enhancing value by offering many of our own on-the-ground experiences and conclude by anticipating some of the future directions for process improvement and innovation in clinical MR imaging.

Rational Design of Bismuth Metal Anodes for Sodium-/Potassium-Ion Batteries: Recent Advances and Perspectives

Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) have drawn widespread attention for application in large-scale accumulation energy because of their plentiful resources and lower cost. However, the lack of anodes with high energy density and long cycle lifetimes has hampered the progress of SIBs and PIBs. Bismuth (Bi), an alloying-type anode, on account of its high volumetric capacity and cost advantage, has become the most potential candidate for SIBs and PIBs. Nevertheless, Bi anodes undergo significant volume strain during the insertion and extraction of ions, resulting in the crushing of structures and a volatile solid electrolyte interface (SEI). As a result, the tactics to boost the electrochemical properties of Bi metal anodes in recent years are summarized in this study. Recent advances in designing nanostructure Bi-based materials are reviewed, and the reasonable effects of architectural design and compound strategy on the combination property are discussed. Some reasonable strategies and potential challenges for the design of Bi-based materials are also summarized. This review aims to provide practical guidance for the development of alloying-type anode materials for next-generation SIBs and KIBs.

Association between Wind Environment and Spatial Characteristics of High-Rise Residential Buildings in Cold Regions through Field Measurements in Xi’an

Research on the correlation between wind and block spatial form focuses mainly on hot and humid cities. However, cold regions are also experiencing high summer temperatures due to global climate change. Enhancing wind speed in blocks through urban spatial control improves comfort. Existing research cannot be directly applied to cold regions due to natural differences. Using Xi’an as an example, this study explores the impact of high-rise residential block spatial form on internal and external wind environments through field measurements and simulations. Optimal strategies for block planning and architectural design are identified to improve the wind environment. Results show that blocks with high buildings on the south and north sides and low buildings in the middle achieve a more comfortable internal wind environment. Gradually increasing building height from south to north has minimal impact on downwind blocks. Reducing the angle between the main facade and dominant wind direction enhances the residential area’s wind environment. Specific spatial planning and design strategies are summarized for early-stage decision-making.

Programmable and Ultrasensitive Haptic Interfaces Enabling Closed‐Loop Human–Machine Interactions

AbstractIntuitive, efficient, and unconstrained interactions require human–machine interfaces (HMIs) to accurately recognize users' manipulation intents. Susceptibility to interference and conditional usage mode of HMIs will lead to poor experiences that limit their great interaction potential. Herein, a programmable and ultrasensitive haptic interface enabling closed‐loop human–machine interactions is reported. A cross‐scale architecture design strategy is proposed to fabricate the haptic interface, which optimizes the hierarchical contact process. The synergistic optimization of the cross‐scale architecture between carbon nanotubes and the multiscale sensing structure realizes a haptic interface with ultrahigh sensitivity and a wide detection range of 15.1 kPa−1 and 180 kPa, which are improved by more than 900% over the performance of the common interface. The rapid response time of <5 ms and the limit of detection of 8 Pa of the haptic interface far surpass the somatosensory perception of human skin, which enables the haptic interface to accurately recognize interactive intents. A wireless pressure‐data interactive glove (wireless PDI glove) is designed and realizes a round‐the‐clock operation, noise immunity, and efficient interactive control, which perfectly compensate for the flaws of typical vision and voice recognition modes.

The Effects of Rhythm on Building Openings and Fenestrations on Airflow Pattern in Tropical Low-Rise Residential Buildings

Effective passive airflow in low-rise residential buildings in hot-humid environment is crucial to maintaining good indoor thermal comfort for occupants. However, investigation of effects of the rhythm of window openings on achieving a passive airflow pattern in such buildings in the tropical climate of sub-Saharan Nigeria have been rarely studied. Therefore, this research aimed to evaluate the effects of the rhythm of window openings on passive airflow patterns for indoor thermal comfort in low-rise residential buildings in the hot-humid environment of Obosi, Nigeria. It involved experimental research using the Anemometer TA465 instrument for measuring wind velocity, relative humidity, and temperature of the purposively designated buildings in the three layouts of the study area for both wet and dry seasons. Employing the Yamane statistical formula, a sample size of 433 was obtained, and questionnaires were administered to occupants of the studied buildings and analyzed using categorical Regression Analysis (CATREG). The regression analysis showed that p=0.000, i.e. p<0.05 indicating that there was a significant relationship between the type and sizes of windows (elements used in measuring rhythm) and the intensity or force of breeze (a measure of passive airflow pattern). Further analysis of the data involved the use of Autodesk CFD 2018 (Computational Fluid Dynamics) for building wind flow simulations. The result showed variations in temperature levels (indications of differences in indoor thermal comfort) of various indoor spaces of the investigated designated floors and buildings, especially ground floors and the top-most floors of the buildings. The study underscored the need to use architectural rhythm design strategies to create a positive impact on airflow patterns in low-rise buildings, especially in densely built-up urban areas. The results of this study are instructive in noting that in order to attain passive airflow in buildings in the face of challenge of land restrictions, vertical stacking of building floors could be used once an adequate rhythm of window openings is adopted.

Architectural Design Criteria Considering the Circular Economy and Buildability for Smart Disaster Relief Shelter Prototyping

The frequency of natural disasters is exacerbated by the escalating impacts of climate change with the need for effective relief shelters for victims and displaced individuals. Providing accessible and easy-to-assemble relief shelters is essential in addressing these needs. Due to climate-related challenges and the need for sustainable solutions, the integration of circularity principles in shelter design has become imperative. Circular economy principles promote the efficient use of resources, minimising waste generation and the cost of shelters. Moreover, a considerable number of people usually suffer from homelessness, and an increasing number of families live in slums in every part of the globe. All such people are entitled to be housed in affordable, safe, and appropriate shelters for at least several months after a disaster until they can either rebuild their former houses or find somewhere decent to settle after recovering from the hardship. With the aim of investigating the immediate housing needs of people after a disaster, this paper identifies the essential factors that must be taken into account during shelter design. The paper also presents the prototype developed on the basis of theoretical criteria and the identified factors. The paper’s main objectives were to design an easy-to-assemble emergency shelter on circular economy principles, identify critical factors for the circularity and buildability of the shelter, and present a proposed smart shelter acceptance model. The methodology behind the research involves conducting an intensive literature review and creating a novel prototype of a smart disaster relief shelter on the basis of long-run laboratory work and various prototype iterations. The paper presents the details of the novel prototype and shows materials that enhance the circularity of the shelter, according to a unique architectural design strategy of ‘reusing’ materials to enhance circularity practice in the design and construction sectors. The prototype was developed in a workshop after 6 months of reiterations using plastic water bottles, basic pipes, and other reusable materials. Then, by incorporating the essential factors, a set of criteria was designed that can be used as a guide for the architectural design of shelters. The criteria offered in this paper are useful to evaluate each factor’s importance in shelter design. In total, 51 effective factors in designing and constructing such accommodation are presented, clustered into five design strategy groups: social–cultural, physical–technical, environmental, economic, and organisational.

Circularity Indicators as a Design Tool for Design and Construction Strategies in Architecture

This study addresses the challenges and barriers associated with the implementation of circular economy principles in architectural design and construction practices. It highlights the fragmented knowledge and lack of a unified approach to circular design as a major obstacle hindering the adoption of circularity. The existing frameworks for assessing circularity, such as the Material Circularity Indicator (MCI) protocol and the Level(s) assessment protocol, are applied to two projects with a high degree of deconstruction to understand their applicability in the architectural design process and identify their limitations. The study emphasises the significance of considering structural connectivity and circularity strategies during the concept-design stage, advocating for the incorporation of circularity at various scales beyond the microscale of materials. Furthermore, it emphasises the need for early implementation of Design for Disassembly (DfD) strategies on circularity scoring to enable meaningful comparisons of alternative designs using circularity metrics. The findings reveal the variability of circularity indicators based on the hierarchy of disassembly and highlights an early-stage design approach to deconstruction strategies to achieve circularity in architectural design. Overall, this study upscales the significance of a comprehensive and integrated approach to circularity in architectural design practices.

Future effectiveness of passive house design strategies

Passive architectural design strategies have been an effective response to the energy crisis of the 20th century. In temperate climates, their integration results in thermal behaviors that combine indoor comfort and energy efficiency. However, projected future climate change scenarios will not offer the same performances, resulting in such strategies being less effective. The objective of this work is to quantify the relative change in the effectiveness of passive design strategies in dwellings for arid temperate-cold climates (Bwk), taking the city of Mendoza (Argentina) as an example. Regarding future climate projections for warm arid climates (Bwh), using the CMIP5’s RCP8.5 scenario, equivalent to the IPCC’s CMIP6 SSP85 scenario, the results show a 20% decrease in the number of hours in annual comfort, with a 24% increase in the need for passive summer strategies.

Financial inclusion and low-carbon architectural design strategies: solutions for architectural climate conditions and architectural temperature on new buildings.

The objective of this research is to explore the potential of financial inclusion and low-carbon architectural design strategies as solutions to improve the thermal comfort and energy efficiency of new buildings in different architectural climate conditions. The manufacture sector, which accounts for about 40% of all yearly greenhouse gas releases, has been stimulating with trying to reduce the amount of energy it consumes and the detrimental effects it has on the climate, in accordance with the standards outlined in the 2016 Paris Agreement. In this study, panel data analysis is used to examine the connection between green property financing and carbon dioxide emissions from the building sector in one hundred and five developed and developing countries. Although this analysis finds a negative correlation among the development of environmentally friendly real estate financing and firms' worldwide carbon dioxide emissions, it finds that this correlation is most robust in developing nations. A number of these countries are experiencing an unregulated and rapid population explosion, which has boosted their demand for oil, making this discovery essential for them. The difficulty in securing green funding during this crisis is slowing and even reversing gains made in past years, making it all the more important to keep this momentum going during the COVID-19 outbreak. It's critical to keep the momentum going by doing something.

Tourism architecture design strategy in tourism area planning based on G-DINA model

Abstract Tourism architecture is an important material guarantee for carrying out tourism activities in scenic spots and is an important part of the tourism system. This paper analyzes the theory and structure of the G-DINA model in detail. To conceptualize the geospatial tourism architecture, form a conceptual cognition, and establish a basic geospatial tourism architecture cognitive model. Then the G-DINA model is brought into the basic cognitive model, and cognitive judgments are made using observation of tourism building features to form a G-DINA-based geospatial cognitive model of tourism buildings for planning and design of scenic tourism buildings. Experimental proof: By comparing the number of tourists in a tourist area for two months, it is obvious that the number of tourists in the second month has increased by 592 compared with the number of tourists in the first month, which is 160% of the number of tourists in the first month, and the comprehensive index of tourism economy has increased from 0.08 to 0.5, with an annual growth of 8.3%, showing a gradual upward trend in general. Accordingly, it can be considered that the attractiveness and competitiveness of tourist areas are significantly improved through the rational planning and design of tourist buildings. This verifies that reasonable design of tourism architecture and scientific planning of tourism areas can strengthen the harmony between tourism architecture and local style and surrounding environment, highlight regional characteristics and let them be inherited, and promote tourism development.

MAKING HEALTHY CAMPUS BY TREATING OPEN SPACE

This paper examines the architectural and landscape design strategies for open spaces facilities targeting stress reduction for learning environments of university campuses in a compact urban areas. Literature reviews provide three prevailing perspectives for physical design techniques and operations- healing gardens where greenery and plants produce restorative effects, flexible spaces that accommodate functional needs of different activities, and green buildings that incorporate open space as a catalyst for integrated ecosystem. Corresponding design approaches (landscape design, spatial design and green design) . A comparison of two university campuses with different urban contexts is conducted to identify challenges and opportunities for applying these design approaches. For a compact campus, high-dense surroundings may limit the size of an open space and may ruins the circulation and accessibility. on the other side, a small open space may provide its users more intimate contact with natural restorative elements and also a more controllable microclimate for physical comfort. A healthy campus should encompass diverse open spaces to satisfy different purposes.In this research Finally, a framework that integrates the three approaches will combined to produce a proper design.

Superior strength-plasticity synergy in a heterogeneous lamellar Ti2AlC/TiAl composite with unique interfacial microstructure

Improving the plasticity of TiAl alloys at room temperature has been a longstanding challenge for the development of next-generation aerospace engines. By adopting the nacre-like architecture design strategy, we have obtained a novel heterogeneous lamellar Ti2AlC/TiAl composite with superior strength-plasticity synergy, i.e., compressive strength of ∼2065 MPa and fracture strain of ∼27%. A combination of micropillar compression and large-scale atomistic simulation has revealed that the superior strength-plasticity synergy is attributed to the collaboration of Ti2AlC reinforcement, lamellar architecture and heterogeneous interface. More specifically, multiple deformation modes in Ti2AlC, i.e., basal-plane dislocations, atomic-scale ripples and kink bands, could be activated during the compression, thus promoting the plastic deformation capability of composite. Meanwhile, the lamellar architecture could not only induce significant stress redistribution and crack deflection between Ti2AlC and TiAl, but also generate high-density SFs and DTs interactions in TiAl, leading to an improved strength and strain hardening ability. In addition, profuse unique Ti2AlC(11¯03¯)/TiAl(111) interfaces in the composite could dramatically contribute to the strength and plasticity due to the interface-mediated dislocation nucleation and obstruction mechanisms. These findings offer a promising paradigm for tailoring microstructure of TiAl matrix composites with extraordinary strength and plasticity at ambient temperature.

Using Simulation to Maximize the Solar Energy Utilization in Buildings in Amman, Jordan

This paper discusses the potential for reducing the energy consumption of residential apartments built on slopes in Amman, Jordan, by proposing new regulations to ensure adequate access to solar radiation. The energy-conscious concept has appeared around the world with rising oil prices and a rise of high residential buildings. It is necessary to consider the possibilities of maximizing the use of solar energy in a building through an architectural design strategy. This leads to mandatory regulations at the urban planning and building design level. This paper provides an overview of the Greater Amman Municipality (GAM) regulations in force regarding the availability of sunlight and achieving a healthy building environment. Analytical scientific methods were used in the work. Computer simulations were performed using a parametric design approach to make new decisions to establish new height and setbacks dimensions for apartment buildings in Amman. The present study provides workable guidance based on determining the optimal distance between condominiums on sloping ground, through which both the architects and the urban designers will be able to define the number of floors that will receive sufficient natural lighting.

Architectural Design Strategies for Enhancement of Thermal and Energy Performance of PCMs-Embedded Envelope System for an Office Building in a Typical Arid Saharan Climate

The literature showed many studies that evaluated single or multiple Phase change materials (PCMs) layers in passive, active, or in hybrid configurations for building applications. However, little attention has been given to evaluating the energy performance of buildings when PCMs are used together with other passive design strategies. In this work, the energy performance of an office building in a typical arid Saharan climate is simulated using EnergyPlus when a PCMs-embedded envelope is implemented. The office building was analyzed without/with PCMs using various thicknesses. Results indicated that the annual electrical energy for heating, ventilation and air conditioning (HVAC) could be reduced between 3.54% and 6.18%, depending on the PCM thickness. The performance of the office building, including PCMs, was then simulated using two practical architectural design strategies, namely windows-to-wall ratio (WWR) and rezoning of the interior spaces. Outcomes revealed that the annual energy consumption for HVAC can be reduced from 10% to 15.5% and from 6.1% and 8.54% when WWR is reduced by half to three-quarters, and the perimeter zones are enlarged by one-third to two-thirds of the original space area, respectively. By combining both architectural design strategies and PCM, the annual electrical HVAC energy can be reduced between 12.08% and 15.69%, depending on the design configuration and PCM thickness. This design option provides additional benefits also since it reduces the vulnerability of increasing the lighting and fuel gas heating energy because more perimeter zones are exposed to daylighting and solar radiation, respectively.

Correlation analysis of urban building form and PM2.5 pollution based on satellite and ground observations

Fine particulate matter (PM2.5) pollution is a key issue affecting the health of urban residents. To explore the impact of urban building form on PM2.5 pollution, this study focused on Wuhan, a Chinese megacity. Based on the urban building data, various building form indices were first calculated in grids to quantitatively present the spatial distribution of urban buildings. The city-scale PM2.5 distribution was obtained with satellite remote sensing and ground air pollution monitoring data. The impact of urban building forms on PM2.5 pollution distribution was then analyzed. The results show that the changes in PM2.5 concentration in Wuhan in the north–south direction have a relatively obvious correlation with the windward area ratio of buildings. The dense north–south buildings can slow the spread of near-surface particulate pollution. This finding demonstrates that the building blocking effect of PM2.5 diffusion in Wuhan is significant. The results of this study can provide a reference for urban planning, architectural design, and air pollution control strategies.
