Energy-Efficient Architectural Design of a Banquet Hall with Integrated Tunnel Ventilation: Monitoring Performance During the Transitional Season in China

The construction industry, a significant contributor to global energy consumption and greenhouse gas emissions, is under considerable pressure to adopt transformative approaches. Public buildings, which account for a substantial portion of total energy usage, must balance high standards of thermal comfort with ventilation efficiency. In China, many public buildings are part of urban landscapes, where façade designs often limit natural ventilation. Consequently, technologies like earth-to-air heat exchangers and wind towers are increasingly essential for enhancing natural ventilation. However, research on the efficacy of these systems remains sparse. This study examines the transitional seasonal environment by evaluating the thermal-humidity index of a banquet hall equipped with an earth-to-air heat exchanger system. Using DeST software [DeST 2.0], the study simulates indoor natural ventilation, calculates ventilation rates, and assesses residual heat removal efficiency. The system’s performance is also modeled under various thermal design zones. Results demonstrate that under natural ventilation, the system can achieve a residual heat removal efficiency of up to 490%. Simulations across different climate zones indicate that the system performs best in regions with extreme temperature fluctuations, particularly those with hot summers and warm winters. In these areas, the system reduces the annual temperature difference by up to 56.7%, significantly improving thermal comfort and reducing dependency on air conditioning. In contrast, performance in milder regions like Kunming achieves only a 37.5% reduction in temperature difference. Overall, this study provides valuable insights into energy-efficient design strategies and thermal optimization for banquet halls, with significant potential for energy savings and enhanced occupant comfort.

Reconstructing Energy-Efficient Buildings after a Major Earthquake in Hatay, Türkiye

Türkiye’s earthquake zone, primarily located along the North Anatolian Fault, is one of the world’s most seismically active regions, frequently experiencing devastating earthquakes, such as the one in Hatay in 2023. Therefore, reconstructing energy-efficient buildings after major earthquakes enhances disaster resilience and promotes energy efficiency through retrofitting, renovation, or demolition and reconstruction. To this end, this study proposes implementing energy-efficient design solutions in dwelling units to minimize energy consumption in new buildings in Hatay, Southern Turkiye, an area affected by the 2023 earthquake. This research focused on a five-story residential building in the district of Kurtlusarımazı, incorporating small-scale Vertical-Axis Wind Turbines (VAWTs) with thin-film photovoltaic (PV) panels, along with the application of a green wall surrounding the building. ANSYS Fluent v.R2 Software was used for a numerical investigation of the small-scale IceWind turbine, and DesignBuilder Software v.6.1.0.006 was employed to simulate the baseline model and three energy-efficient design strategies. The results demonstrated that small-scale VAWTs, PV panels, and the application of a green wall reduced overall energy use by 8.5%, 18%, and 4.1%, respectively. When all strategies were combined, total energy consumption was reduced by up to 28.5%. The results of this study could guide designers in constructing innovative energy-efficient buildings following extensive demolition such as during the 2023 earthquake in Hatay, Türkiye.

An Efficient Metaheuristic Technique for Wireless Sensor Network Integrated Micro Grid Environment Using Improved Whale Optimization Algorithm (Iwoa)

Wireless Sensor Network (WSN) nodes require careful power management to maintain long term operation without regular battery changes. Battery replacement can be challenging and expensive in a microgrid scenario where sensors may be installed in remote or i naccessible areas. To extend the life of WSN nodes, energy efficient design and power management strategies should be used. A potential strategy for effectively monitoring, controlling, and managing the distributed energy resources (DERs) inside a microgri d is theincorporation of WSNs with microgrids. This research work uses Improved Whale Optimization Algorithm (WOA) for optimizing the routing and performance. The humpback whale's hunting style served as the inspiration for the WOA, a metaheuristic optimization algorithm. WOA is an optimization technique that is used with MG and WSNs. During the optimization phase, WOA establishes a balance between exploitation and exploration. To increase the lifespan of a WSN in a microgrid, effective energy management i s frequently needed. When considering the dynamic energy availability from renewable sources and the energy requirements of the microgrid components, WOA is used to optimise energy allocation and routing in WSNs. This may lead to increased energy efficiency and longer network longevity. The IWOA attains 97.5% PDR that is higher than the existing state of art techniques.

Analyzing Energy Efficient Design Strategies in High-rise Buildings with Reference to HVAC System

The Global Warming, Climate Change, Energy Depletion, and Carbon emissions are the greatest risks to humanity in the 21st century. Urbanization in many ways increases the lack of energy resources and demands more construction of high-rise towers for a better standard of living. Buildings are responsible for around one-third of global greenhouse gas emissions. With the emergence of the energy crisis, the rise of environmental consciousness, energy-saving measures, and sustainable buildings became a topic of attention. Due to advancements in technology, the design of high-rise buildings has come across various changes with large glass openings, sealed windows, and deep plans which increase the dependency on air conditioning systems (HVAC) thus increasing the demand for more energy consumption inside the building due to mechanical ventilation and air conditioning. In this paper, an attempt has been made to understand the strategies used for designing energy efficient high-rise buildings that can lower the heating and cooling load and thus increase the performance of the high-rise building. The research is based on a theoretical approach and qualitative analysis which is identified from the literature review and secondary case studies, Case studies selected for the study are office high-rise buildings which are sustainable skyscrapers and have achieved lower energy consumption in heating and cooling load compared to the typical office building which shows how an increase in natural ventilation and other architectural design parameters such as building envelop, form, orientation and integration technology like Building Management System (BMS) system can make it more energy efficient high rise building.

Residential Building Energy Conservation in Mediterranean Climate Zone by Integrating Passive Solar and Energy Efficiency Design Strategies

Residential buildings have a list of functions, and one of the top priories is the thermal comfort of its occupants. Thermal comfort can be one of the measurements of successful building performance, and it can be addressed in various ways to provide a good quality indoor climate. The way to address the need for thermal comfort determines the consumption and conservation of energy. Adapting passive strategies and thermal mass to a building can reduce energy consumption significantly. Applying these strategies to a building does not need additional investment from the initial capital, and renovating a building to implement the strategy will cut the energy usage of a building and save the additional financing of new technology for heating and cooling, ventilation, and so on. In this study, two residential buildings located in North Cyprus with the same geographical location, climate zone, and different construction materials were studied. The study aimed to make a technical test to reduce energy consumption and improve energy conservation in the building by applying passive solar and energy efficiency design strategies (PSEEDS). The thermal mass has been used and discussed as an improbable energy technique alongside other insulation materials and shading devices. The article discusses and compares the energy consumption and thermal comfort of traditional Mediterranean houses with contemporary houses. The study uses 2D drawings, 3D modeling, and energy simulation programs to evaluate energy consumption in both real and assumed scenarios. The study finds that traditional Mediterranean homes, with their thick walls and built-in shading mechanisms, require less energy for heating and cooling than contemporary houses. The implementation of passive solar energy efficient design strategies (PSEEDS) significantly reduces energy consumption in both types of houses, but traditional Mediterranean houses still show more efficiency due to their higher thermal mass. The research demonstrates that improving windows, examining the orientation of the structure, altering shade devices, and decreasing infiltration rates can reduce overall energy consumption by up to 34.71% To sum up, in this study, PSEEDS, the performance of thermal mass, and pre-design measures significantly decrease energy consumption. In addition, implementing passive strategies during a renovation of a building also compensates for the investment and lifecycle cost of new technologies and energy usage.

Evaluating the Effectiveness of Energy-Efficient Design Strategies in Achieving Net Zero Energy Building through Reduced Energy Consumption

Abstract: Net zero energy buildings (NZEBs) have emerged as a sustainable and energy-efficient solution to the challenges of climate change and rising energy costs. These buildings are designed to generate as much energy as they consume, resulting in zero net energy consumption. The paper explores the evolution of NZEBs and the latest emerging technologies that are enabling their development, including smart building automation systems, energy-efficient lighting and HVAC systems, vacuum insulation panels, Building Integrated Photovoltaic (BIPV) systems, and advanced sensors. The effectiveness of these strategies is analyzed using Autodesk insights and Revit software. The paper also discusses the comparison of Energy Use Intensity (EUI) before and after implementing energy-efficient and renewable energy techniques, which is crucial in determining their effectiveness. The proposed building achieved a significant 57.3% reduction in energy consumption after implementing various NZEB design strategies, resulting in a mean EUI value of 99.8 kWh/sq. m/year. The analysis was conducted using Autodesk Insights and Revit software, utilizing the Building Information Modeling (BIM) approach for building design. This paper concludeswitha discussion on the future of NZEBs and how they are an important step towards achieving sustainable and efficient energy use in the building sector,resultingincostsavings andreducedcarbon emissions

Impact of Energy Efficient Design Strategies on Users Comfort in Selected Mixed-Use Buildings in Lagos State, Nigeria

Human comfort is a major criterion for mixed-use buildings to be habitable, leading to the usage of technologies such as HVAC and artificial lighting. These devices demand high electricity, causing a 25% rise in building greenhouse gas emissions. It is important for architects to develop energy efficient design strategies in order to maintain and improve user comfort in mixed-use buildings. This study investigated the impact of energy efficiency design strategies on users’ comfort in selected mixed-used building in Lagos State, Nigeria, with a view to identify areas for further improvements. The research adopted a quantitative approach. A structured questionnaire was used to obtain data. The Statistical Product & Service Solutions software was used to analyse the data. The result was presented with the aid of texts, tables and graphs. The findings indicated that building orientation was one of the most important techniques, affecting each dimension of human comfort. This revelation suggests that when adopting energy efficiency measures, a building’s early design stage should focus on enhancing human comfort. The study recommended that professionals conduct critical analysis on buildings in the design stage to guarantee energy-efficient approaches used throughout the planning, design, and construction stages of mixed-use buildings. In order to create sustainable future designs, it is therefore necessary to recognise the significance of energy efficient design techniques on users’ comfort.

Different Façade Types and Building Integration in Energy Efficient Building Design Strategies

Building façades play a major role in improving the effects of outdoor environment conditions on indoor comfort conditions. Façades, which are designed as energy efficiency, are created according to different performance parameters and can offer solutions appropriate for the climatic condition. This paper aims to describe and highlight the role of design and application determinants in building façade types according to energy efficiency in different climatic classes. For this purpose, 12 building façade types in different climate types were investigated and analyzed by a purposive or judgmental sampling technique. Façade analyses have been carried out by considering double skin, adaptive, photovoltaic panel, vertical green, media and structural membrane façades created as a result of developing technological opportunities. Balance of heat loss and gain, preventing overheating, providing daylight and natural ventilation, active and mechanical solutions for climate-sensitive, noise control, recycling and evaluating the initial investment cost are presented. With examinations, it has been determined that different façade systems are innovative construction systems in creating energy efficiency. It has been concluded that the effect of improving indoor comfort conditions of the building by controlling the outdoor environment conditions with the construction of different facade systems is very important in the architectural process. With the development of technology and smart systems, the impact of the façades on the climate analysis and energy efficient design strategies will be much more important in the future

Energy conservation assessment of traditional and modern houses in Sydney

ABSTRACT This study simulates various residential housing construction scenarios, including improved and standard fibro, brick veneer, double brick and fibro with improved flooring. The total heating and cooling energy requirements for each scenario are simulated with a computer program to determine which one is most energy efficient. In the simulation models, construction types and passive solar and energy efficient design strategies (PSEEDS) were varied while other parameters such as wall and roof thickness, windows sizes and general layout were kept constant. The study shows that a standard fibro house had the highest cooling and heating energy requirements (30,721 kWh/yr). The improved reverse brick veneer house had the lowest energy requirement of 9,628 kWh/yr. Amongst all the construction scenarios, the total energy required for cooling was higher than that required for heating. The results show that improved brick veneer, reverse brick veneer and double brick houses have the lowest net energy requirements for heating and cooling compared to the corresponding standard houses. The results indicate that the thermal mass (measured by R value) and PSEEDS incorporated in the construction have significant impact on the energy consumption. Incorporating these design features in the construction of a house can reduce the heating and cooling energy requirements by as much as 69%.

Energy efficiency in housing and socio-economic development in Nigeria

Energy efficient houses consume less energy while maintaining or improving the comfort conditions of occupants. Energy efficient buildings result in less environmental impact and are economically and environmentally sustainable. Residential buildings account for the majority of electricity consumption in Nigeria. Because of the poor state of energy generation and transmission in Nigeria energy efficiency measures are necessary to reduce the energy required in houses. This would substantially reduce the dependence on the grid electricity supply. Energy efficient buildings have tremendous benefits in social, economic, and environmental terms. In economic terms the production of energy-efficient buildings result in growing market demand with higher quality and innovative buildings, and in social terms it leads to improved urban space and local climate, and liveable buildings. Energy efficient buildings also ensure resource efficiency, and reduction of Green House Gas emissions. Energy efficiency in buildings starts from the design of buildings, and through to construction and operation. The objective of this paper is the examination of energy efficiency in housing in Nigeria and its impact upon socio-economic development in the country. The paper focuses on energy-efficient design strategies, and initiatives to achieve low carbon emission in housing in Nigeria The paper examines the housing situation in Nigeria and the phenomenon of urbanisation which has led to unplanned urban growth, grievous housing poverty, slum formation, and near collapse of urban services and infrastructure particularly electricity supply. It affirms the need to adopt energy efficiency in housing and it examines passive design strategies and low carbon initiatives in housing construction. It takes a critical look at the adoption of sustainability practices in housing. The paper asserts that energy efficiency would enhance the growth of electricity consumption and boost the socio-economic development of the country. The paper concludes that energy efficiency is capable of engendering socio-economic development of the country particularly productivity and income growth.

Occupant behaviour lifestyles and effects on building energy use: Investigation on high and low performing building features

Occupant behaviour is known to be one of the key sources of uncertainty in the prediction of building energy use. Extended literature reviews linked the large performance gaps between residential buildings with same properties and similar climate conditions to the way occupants interact with the building envelope and systems. Furthermore, in the last decades, more stringent energy codes have led to energy efficient design strategies with the aim of reaching the nearly-zero energy target. The success of these strategies is now heavily dependent on how the occupants interact with the building, or rather, on the energy-related lifestyles they assume. In line with this, the present study employs building simulations to demonstrate the potential impact of different occupant behaviour lifestyles on the energy use of a Mediterranean (i) residential nearly-zero energy building (nZEB) under-construction and a (ii) Reference Building (RB) whose envelope-driven loads dominate the consumption profile.

An Energy Efficient Lighting Design Strategy to Enhance Visual Comfort in Offices with Windows

A high luminance contrast between windows and surrounding surfaces can increase the risk of discomfort glare, which can diminish office workers’ satisfaction and productivity. Accordingly, it can lead to occupant interventions, such as drawing window blinds or increasing electric light levels, which are intended to enhance indoor visual comfort but counterproductively act to increase energy consumption. Increasing the luminance of the areas surrounding the windows using a supplementary lighting system, such as wall-washing with light emitting diode (LED) linear luminaires, could reduce discomfort glare arising from windowed walls. This paper reports on the results of a study in a typical office room in Brisbane, Australia. The outcomes of this study indicate that creating a luminance contrast of between 11:1 and 12:1 on the window wall in an office room with a 45% window-to-exterior-wall ratio using a supplementary LED system leads to improved subjective assessments of window appearance. The results suggest that such an enhancement could significantly reduce discomfort glare from windows, as well as diminishing the likelihood of the users intending to turn on the ceiling lights or to move the blinds.

An investigation of indoor air quality, thermal comfort and sick building syndrome symptoms in UK energy efficient homes

Purpose – Concern of the deterioration of indoor environmental quality as a result of energy efficient building design strategies is growing. Apprehensions of the effect of airtight, super insulated envelopes, the reduction of infiltration, and the reliance on mechanical systems to provide adequate ventilation (air supply) is promoting emerging new research in this field. The purpose of this paper is to present the results of an indoor air quality (IAQ) and thermal comfort investigation in UK energy efficient homes, through a case study investigation. Design/methodology/approach – The case study dwellings consisted of a row of six new-build homes which utilize mechanical ventilation with heat recovery (MVHR) systems, are built to an average airtightness of 2m3/m2/hr at 50 Pascal’s, and constructed without a central heating system. Physical IAQ measurements and occupant interviews were conducted during the summer and winter months over a 24-hour period, to gain information on occupant activities, perception of the interior environment, building-related health and building use. Findings – The results suggest inadequate IAQ and perceived thermal comfort, insufficient use of purge ventilation, presence of fungal growth, significant variances in heating patterns, occurrence of sick building syndrome symptoms and issues with the MVHR system. Practical implications – The findings will provide relevant data on the applicability of airtight, mechanically ventilated homes in a UK climate, with particular reference to IAQ. Originality/value – IAQ data of this nature is essentially lacking, particularly in the UK context. The findings will aid the development of effective sustainable design strategies that are appropriate to localized climatic conditions and sensitive to the health of building occupants.

Lessons Learned from Field Monitoring of Two Radiant Slab Office Buildings in California

In this paper we present the results from field studies of two low-energy office buildings in California, both using radiant slab ceiling systems (thermally activated building systems, TABS) for primary cooling and heating in the buildings. Both buildings are certified LEED Platinum and incorporate a wide range of energy efficient technologies and design strategies, including TABS, advanced shading systems, underfloor air distribution, chilled beams, ceiling fans, natural ventilation, and photovoltaic panels. Findings and analysis from the following building performance assessment techniques will be discussed.•Occupant satisfaction survey. Occupant surveys are an invaluable source of information for describing how well the building is providing a high quality indoor environment for the occupants. In addition, the survey results are also compared against a large benchmark survey database of over 50,000 occupants.•Wireless measurement system. A network of wireless sensors was installed in selected zones of the buildings to provide additional more detailed information about the operation and control of the radiant slab system. This data was combined with trend data from the building management system (BMS) to examine the performance of the buildings during both winter and summer conditions. Some control issues were identified and corrected based on these measurements.•Energy performance analysis. We collected utility data for 2014 in one of the buildings and used this information to determine the building's Energy Star rating.

Indoor air-quality investigation in code for sustainable homes and passivhaus dwellings

Purpose– Energy efficient building design strategies are growing in popularity, promoted through increased awareness of climate change, rising energy prices, global consciousness and a demand for energy security. To aid this design process, assessment tools such as Code for Sustainable Homes (CSHs) and Passivhaus were introduced in the UK. However, it is suggested that these tools prioritise energy efficiency over occupant health through a fundamental lack of attention to indoor air quality (IAQ). The purpose of this paper is to investigate IAQ in selected dwellings built using CSHs level 6, level 3 and Passivhaus homes in the UK.Design/methodology/approach– Using a case study approach, the investigation consisted of IAQ measurements during summer and winter months, occupant diaries and occupant interviews.Findings– The results from the IAQ measurements show the recommended maximum level of 1,000 ppm was breached in all three Code 6 and two Code 3 homes, with levels slightly below this limit in the two Passivhaus homes. Measurements found high levels of formaldehyde, carbon dioxide and low levels of relative humidity.Practical implications– There is a need for the adequate consideration of IAQ in sustainable assessment methods, including the use of mandatory credits to ensure occupant health is not disregarded in the drive towards zero carbon.Originality/value– These results can be used to recognise areas of improvement in the CSHs and Passivhaus standard, and the design of energy efficient homes in general. Research of this nature is essential to ensure occupant health is not sacrificed through the drive towards zero carbon.

Indoor air quality and the suitability of mechanical ventilation with heat recovery (MVHR) systems in energy efficient social housing projects: perceptions of UK building professionals

The quality of indoor air in energy efficient buildings is a significantly important yet under-researched area, particularly in a social housing context. This study investigated perceptions of UK building professionals regarding the effect of energy efficient design strategies on indoor air quality. In-depth interviews were conducted with building professionals of four recently completed UK energy efficient social housing projects. The interviews explored perceptions of the importance of indoor air quality consideration during the design process, the impact of energy efficient design strategies on indoor air and the application of Mechanical Ventilation with Heat Recovery (MVHR) systems in a social housing context.The results suggest a significant lack of attention to indoor air quality in energy efficient social housing projects; attributed to a lack of knowledge, perceived costs associated with indoor air quality strategies, focus on energy efficiency goals and a fundamental lack of motivation.

Design strategy for networking membrane module and heat exchanger for direct contact membrane distillation process in seawater desalination

An energy-efficient design strategy for networking membrane modules and heat exchangers in membrane distillation (MD) process was developed in this work. A numerical simulation model was used to describe heat and mass transfer in direct contact type MD membrane module. Mass transfer coefficients were evaluated under different feed flow rates and feed temperatures. Feed flow rate had the predominant effect on the mass transfer coefficient, while feed temperature had a minimal effect. Thus, an empirical equation for the mass transfer coefficient relative to feed flow rate was employed in the simulation to estimate flux and outlet temperatures of membrane module. This approach was verified by two-stage module test results, which showed a good correlation with simulation results. After comparison of different unit process designs, a desired one including partial brine recycle scheme was selected due to the highest efficiency of energy utilization. Replications of a selected unit process will be useful for design of a large scale MD process.

The Energy-related Impacts of Social Factors of Rural Houses in Southwest China

BackgroundIn the last 30 years, the average energy consumption of one person has risen from 80 kgce to 204 kgce in Chinese rural areas. Considering rural areas in China occupy over a half of China's population, the study on energy usage of rural houses is crucial to the development of building energy efficiency of China. Researchers have conducted many studies on this situation, and the climate and technology are mainly considered in these studies. However, in recent years, great changes have taken place in terms of social factors of rural areas in China, for example, rural migration to the cities and gender imbalance. Some changes may lead the rural occupants to a high-carbon life-style. ObjectivesThis research exploits the data collected from rural houses in southwest China and aims to establish which factors relate to occupant social aspects, and to what extent affects energy-related characteristics in rural houses. We hypothesize, in rural houses, that the energy efficient design strategies are not only related to climatic and building envelope physical characteristics but also may be derived with the particular considerations on social factors. Methods50 houses in Tongzi rural area of Chongqing city were selected as the samples. In this paper, the social factors lie in three folds in this research, occupants’ demographics, life patterns, and behaviors. The energy-related characteristics embrace three aspects: thermal comfort, predicted energy consumption, and heating methods. Measurements on energy usage and environmental performance were conducted for each house. Also, we used semi-structured interviews on social factors for each family. The process of life patterns was observed by the researchers. In addition, statistics from the local government were used. The variables in this research are investigated by linear regression, one-way ANOVA, and contingency analysis. ResultsThis study shows the female group preferred to warmer thermal conditions and spent 33% more hours in kitchens which consume over 50% total building energy in rural houses. The group with more hours per day spent outside reported the lower level at the indoor operative temperature, compared with the group with more indoor hours (P-value is 0.042). In addition, two basic heating choices in winter were adopted by rural occupants: charcoal braziers (28.6%) and indoor sun exposure (71.4%). Also, the use of charcoal braziers compromised with aging. ConclusionAlthough the climate and the building physical characteristics are crucial to building energy consumption and indoor environmental performance, this paper demonstrated that some social factors related to residents can affect the energy-related components, especially in the free running rural houses.

How organisational behaviour and attitudes can impact building energy use in the UK retail environment: a theoretical framework

We investigate attitudes to energy-management tasks within a retail organisation, and reflect on links between organisational structure, staff behaviours and energy-efficient design strategy. Research was conducted amongst operational UK shop-floor staff in a large global supermarket chain, using a focus group methodology. We consider the interplay of individual, organisational and technical considerations for energy management and present a preliminary theoretical framework to identify key drivers of environmental behaviours in the workplace. The model is derived from three sources; existing behavioural theory in the domestic arena; Value, Belief, Norms Theory [Stern, P. C. (2000). Toward a coherent theory of environmentally significant behavior. Journal of Social Issues, 56(3), 407–424.], goal-setting theory [Cheng, M. M., Luckett, P. F., & Mahama, H. (2007). Effect of perceived conflict among multiple performance goals and goal difficulty on task performance. Accounting and Finance, 47, 221–242. Locke, E. P., & Latham, G. P. (2002). Building a practically useful theory of goal setting and task motivation. A 35-year odyssey. American Psychologist, 57(9), 705–717.] and our original qualitative data. Our research suggests two key insights. First, the wider organisational and structural context is likely to be more relevant to behavioural outcomes than personal environmental attitudes. Second, energy management is prone to multiple-goal conflicts, with a related negative impact on task performance. Better aligned user-centred approaches to successful energy-efficiency building design, operation and management are identified as key to manage energy effectively in stores. This is an area currently underplayed in the literature, and the theoretical framework has potential application across different energy-management contexts in a range of organisational environments.
