Принципы экологической и биофильной архитектуры в проектировании иранских жилых комплексов с целью повышения их качества
Аннотация
Современная эпоха сталкивается с заметным отрывом городских жителей от природы, и эта проблема имеет первостепенное значение. Архитектурные и городские пространства, якобы предназначенные для непосредственного общения с миром природы, к сожалению, не оправдали ожиданий: экологические последствия, стерильные городские ландшафты и архитектурные сооружения не соответствуют естественным потребностям человека. Среди этих пространств жилье, являющееся ключевым элементом повседневной жизни, подверглось заметному снижению качества пространства в ходе процессов модернизации и индустриализации. Перспективным направлением повышения качества жилой среды в нашу эпоху является внедрение современных архитектурных парадигм, в частности экологического и биофильного дизайна. Эти инновационные архитектуры, основанные на глубокой связи с природой, способны удовлетворить духовные и психологические потребности современных людей, предлагая трансформационный подход к созданию жилых пространств, которые соответствуют миру природы и заботятся о благополучии обитателей. В данном исследовании использована прикладная методология, сфокусированная на описательно-аналитическом подходе, а сбор данных сосредоточен на изучении библиотечных ресурсов и последующем контент-анализе. Полученные результаты подчеркивают потенциал для повышения качественного уровня жилых комплексов в Иране путем локализации принципов и критериев экологической и биофильной архитектуры. Благодаря внедрению этих местных принципов в проектирование и реализацию жилищных проектов можно добиться качественного улучшения. Такой подход не только повышает общее качество жилых комплексов, но и создает более благоприятные условия для благополучия и удовлетворенности их жильцов.
1. Introduction
In the realm of constructing residential buildings today, a notable concern arises from the disproportionate focus on quantity at the expense of addressing human needs, both psychologically and structurally. This emphasis on sheer volume has led to a decline in the overall quality of built environments. The oversight in fostering harmonious coexistence among individuals, architecture, and nature has resulted in a failure to meet spiritual and psychological human needs. The inadequate integration of nature into the physical living environment has contributed to the rise of various mental, physical, and social ailments in societies, making it a pivotal factor in contemporary urban human challenges. Addressing these issues, innovative approaches in architecture have surfaced, characterized by ecological and biophilic principles. Ecological architecture proposes a design approach that establishes a symbiotic relationship between architecture and the natural environment, minimizing harm to the ecosystem and mitigating negative environmental impacts. In tandem, biophilic architecture aims to cater to diverse biological and psychological human needs. This research delves into the application of these principles within the context of designing residential complexes in Iran. The study employs an applied research method with a descriptive-analytic research nature. The findings underscore that by localizing the principles and criteria of ecological and biophilic architecture, aligning them with the quality indicators of housing in Iran, and integrating these native principles into the design and implementation of residential complexes, a substantial enhancement in their qualitative status can be achieved.
2. Main results
2.1. Ecological architecture
Ecological architecture, alternatively referred to as sustainable or green architecture, embodies a design and construction philosophy geared towards mitigating the adverse effects of buildings on the environment. This approach entails the development of structures that exhibit environmental responsibility and resource efficiency at every stage of their existence, spanning from initial planning and design through construction, operation, maintenance, renovation, and eventual demolition . In alignment with this ethos, ecological architecture places emphasis on the following principles:
Designing to imbue significance into the surroundings, Formulating solutions for challenges and design issues rooted in environmental considerations, Crafting designs that respond to both environmental conditions and human needs, Integrating nature into the design process, with a keen focus on evaluating the impact of design choices on the environment.
2.2. Principles of ecological architecture
Luis De Garrido has developed certain ecological indicators to carry out green architecture that fits perfectly into the natural ecosystem. So principles that can nurture ecological architecture are given in the table below (Table 1)
Table 1 - Principles of ecological architecture with examples [2]
Principles of ecological architecture | Example |
Optimal use of natural and artificial resources | Management of Water Resources: Gathering rainwater and repurposing wastewater |
Reduction in level of energy consumption | Application of Smart Systems: Adjusting shade angles, regulating ventilation systems, and controlling lighting in response to external environmental changes |
Promoting the use of renewable resources | Renewable Energy Systems, like solar panels and wind turbines |
Cutting back on waste and emissions | Utilization of Ecological Materials: Incorporating environmentally friendly, recyclable, and intelligent materials |
Limiting maintenance and building cost of buildings | Synchronizing with Nature and Climate: Employing natural ventilation, optimal positioning of openings, appropriate lighting, and environmentally conscious design |
Improve the quality of life of occupants | Fusion of Architecture and Green Spaces: Incorporating green roofs, verdant facades, and expanding ground-level greenery. This involves shading, preserving sunlight, minimizing and adjusting temperature, and managing humidity levels |
2.3. Biophilia and biophilic architecture
Biophilia refers to the natural and inherent human bond with the environment and living entities. Coined by biologist Edward O. Wilson in the 1980s, the concept suggests that humans possess an instinctive attraction to nature and various life forms. This affinity is thought to have its roots in our evolutionary past when humans lived in closer proximity to the natural world. On the other hand, biophilic architecture is a design approach that strives to infuse aspects of nature into constructed spaces. Its objective is to develop environments that promote well-being, alleviate stress, and elevate overall quality of life by integrating natural elements, patterns, and materials. The aim is to craft surroundings that resonate with our intrinsic connection to the natural world .
2.4. Biophilic design approaches
Biophilic principles can manifest in design through various methods, broadly categorized into two main approaches.
The initial approach involves the direct integration of nature into design. This entails maximizing the presence of nature within human spaces by incorporating elements such as plants, natural light, and ventilation. Traditional construction materials like stone and wood can be replaced with their natural counterparts. Interior and exterior spaces can feature images, symbols, and signs inspired by natural landscapes, fostering a direct and unmediated connection to nature .
On the other hand, the second approach focuses on the indirect utilization of nature's features and properties in design. This involves researching intricate geometric patterns found in natural elements and applying them to architectural structures. By creating complexity reminiscent of the natural environment, designers aim to evoke the appreciation humans have for such intricacy. This form of connection to nature is experienced more indirectly and on a cognitive level .
2.5. Principles of biophilic architecture
After studying and examining biophilic architecture some of the basic principles of this type of Architecture have been identified as described in Table 2:
Table 2 - Principles of biophilic architecture and examples [6]
Principles of biophilic architecture | Example |
Prospect | Lighting in the field of vision (windows - bright walls); the possibility of going to a far point for a better view; Horizon - the presence of the image of the sky (sun, mountains and clouds); The existence of the vision corridor |
refuge | The pattern of the tents (short roof and the view similar to tree branches on top |
presence of water | low brightness with reflective surfaces (association of clean water); running water (representing cleanliness and the presence of oxygen in water) symbolic forms of water; |
Biodiversity | Variety of plants inside and outside the building (tall trees, plants, flowers); windows designed to see nature scenery; outdoor nature with thick plants and animals; |
Variability of the senses | Changing the color of the environment, temperature, air flow, texture and light over time and in different spaces; natural rhythms and processes (ventilation and natural lighting) |
Imitation of nature | Designs inspired by nature; Using patterns - natural forms and textures; fractal patterns; |
Feeling alive | Use of decor, natural materials, decorations, objects and spaces whose main purpose is to create a feeling of joy, surprise and fun. |
Mystery | Complexities discovered by people, The richness of information that encourages exploration; curved surfaces that gradually open the exponential |
2.6. Components of housing quality assessment and their principles
Ensuring housing quality stands as a primary objective within housing programs of developed nations. In Iran, a country propelled through the modernization process, the challenge lies in effectively delivering high-quality housing amidst accelerated changes. The focal point of housing programs and policies revolves around overcoming this challenge. The overarching aim is to facilitate each household's access to housing that aligns with their specific needs, characterized by superior quality, within an environment as conducive as possible, and with the desired occupancy . These aspirations are encapsulated in the "Choosing Quality: Homes that are Suitable for All" housing statement, issued in December 2000. Formerly conducted on a quinquennial basis, inspections have been an annual affair since 2002, ensuring a regular assessment of implemented measures. The comprehensive evaluations encompass a spectrum of qualitative facets. In the pre-1990s era, the Housing Survey primarily focused on scrutinizing adherence to appropriate housing standards, encompassing fundamental prerequisites for housing units . Subsequently, diverse evaluation frameworks emerged, such as the housing health and safety rating system, along with the housing quality component system . These standards, in turn, delineate criteria for both housing and residential environments. The housing quality component system proves versatile, applicable not only to social housing but also across various housing types, serving to enhance residential designs. Consequently, a continual critique of residential space quality is imperative to attain desirability in this realm. The significance of this evaluation extends to all internal and external spaces related to housing. The evaluation involves assessing the satisfaction, comfort, or well-being levels of residents. Leveraging these components allows for a comprehensive examination spanning individual, collective, and national levels (Table 3).
Table 3 - Housing Quality indicators and their criteria
Quality indicator | Criteria |
Physical and spatial | The qualitative examination of housing necessitates a thorough consideration of its physical attributes. These elements extend beyond mere compliance with minimum standards for factors like household density, individual housing density, individual rooms density, and per capita floor area. Given that much of our environmental perception is visually driven, and visual perception is fundamentally rooted in the physical realm, the physical quality of housing holds a significant role. This quality is intimately tied to critical concepts such as identity, vitality, familiarity, and memorability. Essentially, the physical components of housing serve as the framework for life, shaping the landscape in which social interactions unfold. Consequently, enhancing physical quality requires a comprehensive assessment of factors like land size and shape, financial resources, human resources, building materials, technology, and effective management and supervision. |
Structural | Designing and overseeing technical aspects, as well as adhering to engineering standards during the implementation of structures, underscores the importance of a well-conceived structure. The scrutiny involves assessing the resilience of building materials relative to climatic conditions and the production state, employing methods for reinforcement, and ensuring compliance with statutes and regulations. It is imperative to acquaint engineers with contemporary construction techniques, continually updating their knowledge in the realms of design and implementation. Within this framework, the evaluation encompasses the structure itself, the materials used, equipment considerations, maintenance standards, and the cost associated with housing repairs. This comprehensive approach ensures that the technical aspects align with established engineering standards, promoting effective and sustainable structures. |
Functional | Functional quality encompasses various aspects, including the quantity and dimensions of rooms, as well as the appropriateness of housing and its suitability for the needs of family members. Evaluation systems often incorporate an examination of housing from an energy perspective within this category. By taking into account the provision of adequate facilities and services, the overall acceptability of housing improves, contributing to both housing health and, consequently, the well-being of its residents. Prioritizing these factors enhances the functional quality of housing, making it more conducive to a healthy and comfortable living environment. |
Environmental | The assessment of housing is significantly influenced by the residential environment, serving as a pivotal factor in all evaluations. A residence situated in an unsuitable environment is unable to fulfill the secondary needs of its occupants, particularly in terms of environmental quality. Environmental quality encompasses diverse facets of the living environment, spanning the standards of housing facilities, safety, security, access, housing types, and surrounding features, considering aspects such as functionality, visual appeal, and physical characteristics. Urban facilities and infrastructures form an integral part of this evaluation, constituting a broad spectrum of physical elements that facilitate various urban functions. These elements contribute to the composition and formation of urban spaces, playing a crucial role in various aspects of residence, activity, rest, leisure, and, overall, in enhancing the quality of urban life. In essence, the quality of the residential environment and its associated facilities is a cornerstone in determining the overall quality of housing and the urban living experience. |
The human needs | Assessing the quality of housing involves a comprehensive evaluation of satisfaction across various dimensions. These include the physical, functional, social, cultural, identity, aesthetic, security, facilities, equipment, accessibility, and neighbor-related aspects . Satisfaction in these diverse categories forms a critical component of the overall quality assessment of housing. By considering these multifaceted elements, a more nuanced and holistic understanding of the living experience is achieved, encompassing not only the tangible features of the dwelling but also its social and cultural context, ultimately contributing to a more accurate and inclusive measure of housing quality. |
2.7. Compilation of housing quality components based on ecological and biophilic principles
As mentioned, The Housing Quality Assessment involves a thorough examination and measurement of a housing's desirability across five distinct yet interconnected areas. Meeting the standards set in all these components signifies that a housing unit is qualitatively desirable and appropriate. However, the current research goes beyond merely assessing the desirability of Iranian urban housing based on existing standards. It seeks to elevate the quality of domestic residential complexes by incorporating ecological and biophilic architectural approaches. The aim is to align the principles advocated by the global field of ecological and biophilic architecture with the components of Housing Quality Assessment in Iran. This localization process involves adapting these principles to the specific indicators of housing quality in the Iranian context. By doing so, the research contends that the quality of Iranian residential complexes can be enhanced, fostering a synergy between internationally recognized ecological and biophilic architectural principles and the unique criteria used in the assessment of housing quality in Iran (Table 4). This approach represents a comprehensive strategy to not only evaluate but also improve the quality of residential complexes within the Iranian urban landscape.

3. Conclusion
For years, ecological and biophilic architectural principles have been integral to designing diverse building types in developed countries, spanning residential, educational, cultural, commercial, and service structures. Extensive research and projects have demonstrated that applying these principles enhances buildings environmentally, functionally, and structurally. This study, however, focuses on the unique challenge of implementing these principles in Iranian residential architecture to elevate the quality of domestic housing complexes, considering existing infrastructure limitations. The solution proposed involves localizing ecological and biophilic architecture principles, adapting them to the design of contemporary residential complexes in Iran, and thereby enhancing their overall quality. The author establishes a specific model incorporating global principles of ecological and biophilic architecture, aligning them with qualitative housing components such as Physical and Spatial Quality, Structural Quality, Functional Quality, Environmental Quality, and Human Needs. Each principle is integrated into its corresponding indicator, resulting in a native model tailored for evaluating Iranian residential complexes. This model, outlined in Table 4, can be effectively employed in the design and implementation process of modern Iranian residential complexes to elevate their quality and create more favorable living conditions for residents.
