Green architecture represents a transformative approach to building design that integrates ecological principles to minimize environmental impact and optimize resource use [1]. Central to this approach is the emphasis on creating energy-efficient and resourceconscious structures, which involves not only enhancing the operational efficiency of buildings but also considering the environmental footprint of construction materials and processes [2]. Foundations of green architecture include principles such as efficient building envelopes, renewable energy integration, and the use of sustainable materials to create structures with minimal waste and reduced energy demands [3]. Additionally, site-specific strategies like optimizing natural light, managing storm-water runoff, and incorporating green spaces are essential for harmonizing buildings with their natural surroundings [4]. The principles of green building design focus on selecting low-impact materials, utilizing renewable energy sources, and implementing water management systems to ensure sustainable resource use [5]. Furthermore, green architecture aims to mitigate the adverse effects of construction on the environment through careful site selection, sustainable material choices, and the promotion of biodiversity [6].
By incorporating natural ventilation, strategic building orientation, and passive design techniques, green architecture not only improves energy efficiency but also enhances indoor environmental quality, contributing to the health and wellbeing of occupants while supporting overall ecological balance. Sustainable building techniques play a pivotal role in reducing the environmental impact of construction and enhancing building efficiency [7]. These techniques involve selecting green building materials such as bamboo, reclaimed wood, and recycled steel that minimize resource use and have a lower environmental footprint compared to traditional materials [8]. Additionally, innovative methods like integrated cooling systems and green roofs contribute to energy efficiency and ecological benefits [9]. Integrated cooling strategies utilize outdoor air to reduce reliance on mechanical systems, while green roofs and walls improve insulation, manage storm-water runoff, and support biodiversity [10]. The adoption of energy-efficient systems, renewable resources like solar panels and wind turbines, and smart building technologies further advance sustainability by optimizing energy use and reducing greenhouse gas emissions [11]. Performance metrics and certification systems, such as LEED and BREEAM, are crucial for evaluating and guiding the sustainability of buildings, ensuring they meet environmental and performance standards [12].
These comprehensive approaches help create greener, more efficient buildings that contribute to both environmental health and occupant well-being. The future of green architecture is marked by the increasing adoption of adaptive and sustainable design practices that respond to environmental challenges and technological advancements [13]. Adaptive building systems, incorporating technologies like automated shading and smart windows, dynamically adjust to environmental conditions, optimizing energy use and enhancing comfort [14]. This trend enhances building resilience against climate change. Additionally, integrating renewable energy technologies, such as solar panels and geothermal systems, is becoming standard, enabling energypositive structures that generate their own power [15]. Adaptive reuse of existing buildings is also gaining traction, preserving resources, reducing waste, and revitalizing urban areas [16]. Emerging trends include the use of bio-based materials, such as mycelium and hemp Crete, and the shift towards regenerative design, where buildings actively contribute to environmental restoration [17]. These innovations reflect a move towards more sustainable, resilient, and restorative built environments.
Green building design represents a transformative approach with significant potential across various domains, emphasizing sustainability and the reduction of environmental impact through innovative construction practices [18]. In light of the growing global population and the corresponding increase in environmental degradation, which ultimately affects human health, green architecture has emerged as a crucial solution [19]. This approach integrates renewable energy sources, sustainable materials, and energy-efficient systems, which collectively contribute to environmental sustainability by reducing greenhouse gas emissions and mitigating the effects of climate change a pressing issue today. To thoroughly understand the effectiveness of green building design, various articles published in highly reputable journals over the past two decades have been studied. Initially, the core principles of green architecture were explored, including the utilization of renewable energy and sustainable materials. Subsequently, the focus shifted to specific design strategies that enhance energy efficiency and occupant well-being. Finally, the adaptability and applications of green building design were examined across various sectors, particularly in urban housing developments. For instance, green building techniques have been applied in retrofitting existing urban buildings to improve energy efficiency and reduce operational costs. After an in-depth study, it was revealed that green building design contributes significantly to reducing energy consumption and carbon emissions, making it a versatile and effective solution for addressing environmental challenges associated with traditional construction practices.
Foundations of green architecture are crucial for establishing a sustainable approach to building design and construction [20]. This foundation involves integrating ecological principles into architectural practices to reduce environmental impact and promote the efficient use of resources [21]. At its core, green architecture emphasizes a holistic approach to building design that considers not only the operational energy use of a structure but also its construction materials, lifecycle impacts, and overall environmental footprint [22]. The foundation of green architecture includes key principles such as minimizing energy consumption through efficient building envelopes, incorporating renewable energy systems, and utilizing sustainable building materials [23]. These principles are designed to create buildings that are not only energy-efficient but also resource-efficient, reducing waste and promoting the use of materials that have a lower environmental impact [24]. For example, the use of high-performance insulation and energy-efficient windows can significantly reduce the energy required for heating and cooling, while selecting materials with low embodied energy can minimize the overall environmental impact of the construction process [25].
Moreover, the Foundations of Green Architecture also extend to the site and environmental context of the building [26]. This includes considerations such as site orientation, landscape design, and the integration of natural systems [27]. Proper site orientation and design can optimize natural lighting, reduce heat gain, and enhance passive solar heating, thereby reducing the need for mechanical systems and improving energy efficiency [28]. Landscape design plays a role in managing storm-water runoff, reducing heat islands, and enhancing biodiversity around the building [29]. Additionally, integrating natural systems such as green roofs, rain gardens, and habitat areas helps to mitigate the impact of the building on its surroundings and contributes to ecological health [30]. By focusing on these foundational elements, green architecture aims to create buildings that are not only environmentally sustainable but also harmoniously integrated with their natural context, providing benefits to both occupants and the broader ecosystem.
Principles of green building design
The principles of green building design are fundamentally focused on creating structures that are energy-efficient, environmentally responsible, and healthy for occupants [31]. At the core of these principles is the need to minimize resource consumption and environmental impact throughout a building’s lifecycle (Figure 1) [32]. This begins with the selection of sustainable materials, which are chosen for their low environmental footprint, durability, and the ability to be sourced locally [33]. Such materials include recycled content, rapidly renewable resources like bamboo, and low-emission products that contribute to better indoor air quality [34]. Additionally, energy efficiency is prioritized through the use of passive design strategies that take advantage of natural light, ventilation, and thermal mass to reduce the need for artificial heating and cooling systems [35]. The integration of renewable energy technologies, such as solar panels and wind turbines, further enhances the sustainability of green buildings, making them less dependent on fossil fuels and reducing their overall carbon emissions [36,37].
Figure 1:Life-cycle assessment of green building [37].
Moreover, green building design extends beyond the physical structure to encompass water management systems that aim to reduce water consumption and promote water reuse [38]. Implementing rainwater harvesting systems, low-flow plumbing fixtures, and greywater recycling are some of the techniques that contribute to water conservation efforts in green buildings [39]. The goal is to create a closed-loop system where water is efficiently used, treated, and recycled, reducing the burden on local water resources [40]. Furthermore, natural building techniques that use materials like earth, straw, and wood are essential to green architecture [41]. These materials not only have a lower environmental impact but also provide excellent insulation and thermal mass, helping to maintain indoor comfort without excessive energy use [42]. The holistic approach of green building design ensures that all aspects of the building materials, energy, water, and indoor environment are optimized for sustainability, contributing to a healthier planet and improved quality of life for building occupants [43].
Architectural impact on natural environment
Green architecture is deeply concerned with the impact of buildings on the natural environment, recognizing that construction activities are a significant source of environmental degradation [44]. Traditional building practices often lead to habitat destruction, increased carbon emissions, and a significant depletion of natural resources [45]. Green architecture seeks to mitigate these effects by adopting sustainable practices that reduce the environmental footprint of buildings [46]. This involves careful site selection that avoids ecologically sensitive areas, the use of materials that are sustainably sourced and have a low embodied energy, and the incorporation of green spaces such as gardens, green roofs, and walls [47]. These strategies not only reduce the environmental impact of buildings but also help to restore and enhance the natural environment [48]. By integrating buildings with their natural surroundings, green architecture creates a symbiotic relationship between the built and natural environments, promoting biodiversity and improving the quality of life for all inhabitants [49].
The environmental comfort provided by green buildings is another crucial aspect of their impact on the natural environment [50]. Green architecture aims to create indoor spaces that are not only energy-efficient but also conducive to the health and well-being of occupants [51]. This involves optimizing thermal comfort, improving indoor air quality, and maximizing natural lighting, which reduces the need for artificial lighting and heating [52]. These elements are critical in reducing the overall energy consumption of buildings, which in turn reduces their environmental impact [53]. Additionally, by minimizing the use of toxic materials and incorporating natural elements into building design, green architecture creates environments that are healthier for both people and the planet [54]. The emphasis on sustainability in green architecture extends beyond energy efficiency to encompass a holistic approach to building design that considers the environmental, social, and economic impacts of construction [55]. This comprehensive approach ensures that green buildings contribute positively to the environment throughout their entire lifecycle, from construction to operation and eventual demolition or repurposing [56].
Green building strategies
Building orientation is a fundamental green building strategy that significantly influences the energy efficiency and overall environmental impact of a structure (Figure 2) [57]. Proper orientation takes advantage of the building’s position relative to the sun to optimize natural lighting and passive solar heating, which can drastically reduce the need for artificial lighting, heating, and cooling systems [58]. By orienting a building’s longest façade towards the south in the Northern Hemisphere, architects can maximize solar gain during the winter months while minimizing it during the summer, thereby reducing energy consumption [59]. Additionally, proper orientation facilitates natural ventilation, which is essential for maintaining indoor air quality and reducing reliance on mechanical ventilation systems [60]. The strategic placement of windows, shading devices, and reflective surfaces further enhances the building’s energy performance, making it more sustainable and cost-effective over its lifespan [4]. Natural ventilation is another critical strategy in green building design that complements orientation by enhancing indoor environmental quality and reducing energy use [61,62].
Figure 2:Model system of green building [62].
Buildings designed with natural ventilation systems utilize prevailing wind patterns and thermal buoyancy to circulate fresh air through the interior spaces, reducing the need for energy-intensive mechanical ventilation [63]. This not only improves indoor air quality by reducing the concentration of indoor pollutants but also contributes to thermal comfort by regulating indoor temperatures naturally [64]. Techniques such as cross-ventilation, where air is allowed to flow between opposite sides of a building, and stack ventilation, which utilizes the rising warm air to create a cooling effect, are commonly employed in green buildings [65]. These passive ventilation strategies are particularly effective in temperate climates, where they can significantly reduce the building’s energy footprint while providing a healthier indoor environment for occupants [66].
Sustainable Building Techniques are essential for reducing the environmental impact of construction and improving the efficiency of building operations (Figure 3) [67]. These techniques encompass a wide range of strategies that aim to minimize resource use, reduce waste, and enhance energy efficiency throughout the lifecycle of a building [68]. One prominent technique is the use of green building materials, which are sourced from sustainable or recycled materials and have a lower environmental footprint compared to traditional building products [69,70]. For example, materials such as bamboo, reclaimed wood, and recycled steel are favored for their durability and reduced impact on natural resources [71]. Additionally, techniques like integrated cooling systems utilize outdoor air to cool buildings, reducing the reliance on mechanical cooling systems and thereby saving energy [71]. Such systems can include night ventilation strategies that cool the building during cooler nighttime hours, which are then utilized during the day to maintain comfortable indoor temperatures [72].
Figure 3:Green building and sustainability [37].
In addition to material selection and cooling systems, green roofs and green walls are innovative techniques that contribute significantly to sustainable building practices [73]. These living systems not only enhance the aesthetic appeal of a building but also provide multiple environmental benefits [74]. Green roofs, covered with vegetation, help to insulate buildings, reduce urban heat islands, and manage storm-water runoff [75]. Green walls, similarly, can improve air quality by filtering pollutants and provide insulation that reduces energy consumption [76]. The implementation of these techniques also supports biodiversity by creating habitats for various species in urban areas [77]. The integration of such features aligns with broader goals of sustainability by addressing climate resilience, energy efficiency, and ecological impact, ultimately contributing to the development of greener, more sustainable built environments [78].
Green building materials
The selection of green building materials is crucial in minimizing the environmental impact of construction and promoting sustainability (Table 1) [79]. Green materials are typically chosen for their low embodied energy, renewability, and potential to be recycled or repurposed at the end of their lifecycle [80]. For example, materials like bamboo, cork, and reclaimed wood are favored for their rapid renewability and minimal environmental impact compared to traditional construction materials such as concrete and steel, which have a high embodied energy and contribute significantly to carbon emissions [81]. Additionally, green building materials often include recycled content, such as recycled steel or glass, which reduces the demand for virgin materials and decreases waste sent to landfills [82]. The use of low- VOC (volatile organic compounds) paints, adhesives, and finishes is also essential in green building practices, as these products contribute to healthier indoor air quality by reducing the release of harmful chemicals [83].
Table 1:Overview of sustainable green building materials.
Green roofs and green walls are innovative techniques that enhance the sustainability of buildings by providing insulation, reducing the urban heat island effect, and improving air quality [84]. Green roofs, which involve the installation of vegetation on the roof surface, offer several environmental benefits, including improved thermal insulation, reduced storm-water runoff, and increased biodiversity [85]. Similarly, green walls, which incorporate plant life into the building’s façade, contribute to energy efficiency by providing additional insulation and enhancing the building’s aesthetic appeal [86]. The incorporation of these green features into building design supports the overall goal of reducing the environmental impact of construction and creating healthier, more sustainable urban environments [87]. Additionally, they can lower energy costs by reducing the need for heating and cooling, and they promote mental well-being by creating green spaces in densely built areas [88].
Energy efficiency and renewable resources
Energy efficiency and the integration of renewable resources are key components of sustainable building practices that contribute to reducing a building’s overall environmental impact [89]. Energy efficiency measures involve the optimization of building systems and components to minimize energy [90-111] consumption without compromising occupant comfort [112]. This includes the use of high-performance insulation, energy-efficient windows and doors, and advanced Heating, Ventilation, and Air Conditioning (HVAC) systems [113]. The incorporation of renewable energy sources, such as solar panels and wind turbines, further enhances sustainability by providing clean, self-generated power [114]. Additionally, implementing smart building technologies allows for real-time monitoring and adjustment of energy use, ensuring that buildings operate at peak efficiency [115]. By reducing the amount of energy required for heating, cooling, and lighting, buildings can significantly lower their carbon footprint and operational costs.
Renewable energy resources, such as solar panels, wind turbines, and geothermal systems, play a crucial role in further enhancing the sustainability of buildings by providing clean, renewable sources of energy [116]. Solar panels, for example, can be installed in rooftops or integrated into building facades to generate electricity from sunlight, reducing reliance on fossil fuels and lowering greenhouse gas emissions [117]. Wind turbines, when appropriately sited, can contribute to renewable energy production and help offset the building’s energy needs [118]. Geothermal systems utilize the stable temperatures of the earth to provide efficient heating and cooling, further reducing the building’s energy consumption [119]. The integration of these renewable resources into building design not only supports energy independence but also aligns with broader goals of reducing the environmental impact of the built environment.
Performance metrics and building certification
Performance metrics and building certification systems are essential tools for evaluating and ensuring the sustainability of green buildings [120]. These systems provide benchmarks and guidelines for measuring the environmental performance of buildings and help guide the design and construction processes toward achieving sustainability goals [121]. One widely recognized certification system is LEED (Leadership in Energy and Environmental Design), which evaluates buildings based on various criteria, including energy efficiency, water conservation, material selection, and indoor environmental quality [122]. LEED certification provides a comprehensive framework for assessing a building’s sustainability performance and helps to promote best practices in green building design and construction [123].
Another important certification system is BREEAM (Building Research Establishment Environmental Assessment Method), which is widely used in Europe and assesses buildings based on their environmental impact, including energy use, water management, and materials [124]. BREEAM certification helps to identify areas for improvement and encourages the adoption of sustainable practices throughout the building Lifecycle [125]. Additionally, performance metrics such as Energy Use Intensity (EUI), Water Use Intensity (WUI), and Indoor Air Quality (IAQ) are critical for monitoring and managing a building’s environmental performance [126]. These metrics provide valuable insights into the effectiveness of sustainability measures and help guide ongoing improvements to enhance the building’s overall performance and reduce its environmental impact.
Adaptation and Future Trends in green architecture reflect the ongoing evolution of sustainable design practices as they respond to emerging environmental challenges and technological advancements [127]. One significant trend is the increasing adoption of adaptive building systems, which allow structures to respond dynamically to changing environmental conditions. These systems often incorporate advanced technologies such as automated shading devices, responsive insulation, and intelligent lighting controls, which adjust based on real-time data to optimize energy use and enhance occupant comfort [128]. For example, smart windows that change their opacity based on sunlight can reduce glare and heat gain, leading to lower cooling costs and improved indoor climate control [129]. This trend towards adaptability not only improves the efficiency of buildings but also helps in mitigating the impacts of climate change by making structures more resilient to extreme weather conditions and fluctuating temperatures [130,131].
Another prominent trend is the integration of renewable energy technologies into building design, reflecting a shift towards more self-sufficient and energy-positive structures [132]. The use of solar panels, wind turbines, and geothermal systems is becoming increasingly common, as these technologies can significantly reduce a building’s reliance on non-renewable energy sources [133]. Additionally, advancements in energy storage solutions, such as improved battery technologies and thermal energy storage, are enabling buildings to store excess energy for use during peak demand periods or when renewable sources are not generating power [134]. This trend aligns with the broader goal of creating buildings that not only consume less energy but also generate their own energy, contributing to a more sustainable and resilient energy grid [135]. As these technologies become more cost-effective and widely available, they are expected to play a central role in the future of green architecture, driving innovation and enhancing the environmental performance of buildings.
Adaptive reuse in green architecture
Adaptive reuse is an innovative approach in green architecture that involves repurposing existing buildings for new uses, rather than demolishing them and constructing new ones [136]. This practice is increasingly recognized as a sustainable alternative to new construction, as it preserves the embodied energy of existing structures and reduces the demand for new building materials [128]. Adaptive reuse projects often involve retrofitting older buildings with modern amenities and energy-efficient systems, transforming them into functional spaces that meet contemporary needs [137]. By reusing existing structures, adaptive reuse not only conserves resources but also reduces construction waste and minimizes the environmental impact associated with new building projects [138]. This approach is particularly valuable in urban areas, where land is scarce and the preservation of historical buildings contributes to cultural heritage.
Moreover, adaptive reuse aligns with the principles of sustainable development by promoting the efficient use of land and resources [139]. It provides an opportunity to revitalize underutilized or abandoned buildings, breathing new life into them and contributing to the economic and social regeneration of communities [140]. For example, old industrial warehouses can be transformed into vibrant residential or commercial spaces, while maintaining the architectural character and history of the original structure [141]. This not only preserves the cultural significance of the building but also reduces the environmental impact of new construction [142]. Additionally, adaptive reuse can contribute to urban sustainability by promoting higher density development, reducing urban sprawl, and making better use of existing infrastructure [143]. As cities around the world continue to grow and face challenges related to resource scarcity and climate change, adaptive reuse is likely to play an increasingly important role in the future of green architecture.
Emerging trends in sustainable architecture
As the field of sustainable architecture continues to evolve, several emerging trends are shaping the future of green building design [144]. One such trend is the increasing use of smart technologies in green buildings, which enable real-time monitoring and optimization of energy use, indoor environmental quality, and overall building performance [145]. Smart buildings are equipped with sensors, automated systems, and data analytics tools that allow them to adjust lighting, heating, cooling, and ventilation based on occupancy patterns and environmental conditions [146]. This not only improves energy efficiency but also enhances the comfort and well-being of occupants. Furthermore, the integration of smart grids and renewable energy systems allows buildings to produce, store, and manage their energy, contributing to a more resilient and sustainable energy infrastructure [147]. As these technologies become more advanced and affordable, they are expected to become a standard feature of green buildings, driving further improvements in sustainability.
Another significant trend in sustainable architecture is the focus on resilience in the face of climate change. Architects and planners are increasingly designing buildings and communities that can withstand extreme weather events, rising sea levels, and other climate-related challenges [148]. This involves the use of resilient materials, flood-resistant designs, and adaptable infrastructure that can respond to changing environmental conditions [149]. For example, buildings in flood-prone areas may be elevated or designed with water-resistant materials, while those in hot climates may incorporate passive cooling strategies and reflective surfaces to reduce heat gain [150]. The concept of resilience is also being applied at the community level, with the development of sustainable urban planning strategies that promote social cohesion, resource efficiency, and disaster preparedness [151]. As the impacts of climate change become more pronounced, the demand for resilient and sustainable architecture is expected to grow, driving innovation in design, materials, and construction practices.
Future of green building design
The future of green building design is likely to be characterized by greater integration of sustainability principles into all aspects of architecture and construction [152]. One of the key areas of development is the use of bio-based materials, such as mycelium, algae, and hemp Crete, which are derived from renewable resources and have a low environmental impact [153]. These materials offer a sustainable alternative to traditional construction materials, providing benefits such as carbon sequestration, biodegradability, and improved indoor air quality [154]. As research and development in bio-based materials continue to advance, they are expected to play a more prominent role in green building design, contributing to the creation of healthier and more sustainable built environments [155].
Another area of innovation is the concept of regenerative design, which goes beyond sustainability to create buildings that actively contribute to the restoration and regeneration of natural ecosystems [156]. Regenerative buildings are designed to produce more energy than they consume, purify the air and water, and support biodiversity through the integration of green spaces and ecological systems [157]. This approach represents a shift from minimizing environmental harm to creating a positive environmental impact, aligning with the principles of the circular economy [158]. In the future, regenerative design is expected to become a central tenet of green architecture, as society moves towards more holistic and restorative approaches to building design and urban development [159]. The continued advancement of sustainable technologies, materials, and design strategies will be essential in achieving these goals, ensuring that the buildings of the future are not only environmentally responsible but also regenerative and resilient.
