Architectural Education in the Current of Deep Ecology and Sustainability

: As a result of the experience and scientiﬁc research of the authors on the deep ecology and sustainability process, academic courses were created that are run at two stages of educating architecture students. The authors aimed at demonstrating the effectiveness and quality of the courses as well as the rationality of the assumptions and educational methods adopted for their implementation. One of them was the survey method, as a didactic and scientiﬁc experiment and didactic tool. The innovative educational methodology presented in the work may be implemented by other educators at architectural universities in order to improve the quality of teaching design in the spirit of pro-ecological and sustainable development. The result is a long-term action which constitutes a tool to combat the ecological crisis. It consists of bottom-up activities, both in the open landscape (ecovillages) and in the urban context (housing complexes with elements of urban farms and environmental education parks). This is connected with the application of the educational system from the pre-school level in the place of residence up to in-depth academic education.


Introduction
The article discusses the methodology of introducing issues and concepts based on deep ecology and green architecture in the courses:

•
Habitats-the context of place. • Architecture design. Research and design studio: Environmentally-friendly dwelling architecture. • Interior design.
The above courses are conducted by the authors for 1st and 2nd degree students at the Faculty of Architecture of Wrocław University of Science and Technology. In particular, the objectives, methodology, and assumptions of these courses are extensively explained and discussed, indicating their origin and architectural practices significant for their evolution.
Our work relates to the study presented in the article entitled Assessing the impact of a program designed to develop sustainability leadership amongst staff members in higher education institutes: a case study from a community of practice perspective published in Environmental Education Research in 2018 [1]. The study focuses on the Sustainable Leadership Development Program (SLDP) that supports employees as leaders to encourage sustainable development practices within Institution of Higher Education (IHE).
This study highlighted the impact of education for sustainability programs on the professional development of university staff, including academic teachers, both at the individual and institutional levels as leaders in sustainable development. It also suggested ways to increase environmental awareness and the level of employee involvement in the Education For Sustainability (EFS) discourse in these institutions [1].
The importance of higher education institutions as leaders and role models for sustainable development in society has gained increasing recognition in recent years. However, Buildings 2021, 11, 358 2 of 22 despite international calls for the inclusion of education for sustainability in academic curricula, the principles of education for sustainability are still far from being integrated into the day-to-day practices of academic staff, as well as with existing compulsory curricula and educational methods [1].
One of the main reasons for this unfavorable situation is the ambiguity, multidimensionality, and complexity of the concept of sustainable development, which makes it difficult for research and teaching units to develop methods of implementing sustainable development in practice and to educate students for sustainable development. Another major barrier is the scarcity of programs and opportunities for academic teachers to develop in the field of sustainable development [1].
The growing concern for progress towards more sustainable development in architecture poses a serious challenge to both education and research. The required approach is insufficiently visible in interdisciplinary, multidisciplinary, and transdisciplinary research and pedagogy. Significant institutional and intellectual barriers to the development of integrated systems thinking remain a major concern in both research and education. Some questions arise: How can multidisciplinary and transdisciplinary research and education coexist and develop in a meaningful way in today's university structures? How can difficulties in combining the necessary teaching and research be overcome? It seems that without clear, strong, continuous leadership, as well as support, motivation, and rewards for effectively combining "two paths" in academic institutions, development in both science and education will be slow [2].
Sustainability has been identified as a significant issue in architectural design due to the extensive resources needed to make the projects a reality. Architects are responsible for contributing to the protection, preservation, and restoration of the global ecosystem. Sustainable design processes refer to activities that minimize the impact on the natural environment and create healthy living conditions. Attempts at solving environmental problems resulting from the consumerism of societies are undertaken as part of design education at universities of architecture. Courses to prepare students for eco-design in the spirit of sustainable development are becoming more common. However, it turns out that education in this field requires development and changes. Despite the fact that education in ecological and sustainable design is now considered the focus point of many educational programs, design responsibility issues are not treated with the same attention as environmental knowledge. Providing architecture students with only the necessary knowledge and skills in the field of environmental protection is not sufficient preparation for sustainable design. Among the basic features that students of architecture should learn are the sense of responsibility for the design and the ability to convince other designers, contractors, investors, developers, clients, and users to support sustainable design. The term "sustainable" seems to be accurate in relation to design solutions, while the term "responsible" is rather treated as a designer's characteristic. The "designer responsible for the project" should predict the environmental effects of the design, but also its other results, including social and environmental. Introducing students to the principles of ecological design is not enough to convince them of the validity of the idea of sustainable development in architecture and encourage them to implement it in practice [3].
A clear trend in sustainable design education is the shift from fragmentary knowledge to integrative systems that promote interdisciplinary activities. Education in the field of sustainable design in architecture has to apply a holistic approach, taking into account various aspects and conditions. With the awareness that the world is constantly changing and developing, architects should create designs that meet current needs, taking into account future requirements and evolving expectations. Design aims to ensure human health, safety, and well-being, so it is important for students to understand how architecture affects users, as well as society and the environment as a whole. The importance of education in the field of architectural design is invaluable as it develops the sensitivity, knowledge, and design skills of students as architects of the future. The task of academic teachers is to familiarize and train students in how to create sustainable architecture through in-depth observation, analysis, and understanding of the current environment. It is important to encourage and motivate architecture students to take a more comprehensive standpoint on "green architecture" and sustainable ecological design that uses inter-, multi-, and transdisciplinary approaches [2,3]. Therefore, the knowledge and practice in this area becomes so important, both at the pre-school level, educating children in their place of residence, and finally at the academic level-identifying problems and taking actions to eliminate disturbances of the ecosystem at its source by means of implementing remedial actions with a long-term beneficial impact on the environment. Deep ecology is a kind of philosophy of life as well as a long-term movement describing the approach to the ecological crisis. It shows the reasons of the problem and suggests appropriate educational and practical activities. As a philosophy of life, it appeared in Norway at the turn of the 1970s. [4][5][6][7][8][9]. The methodology of the research conducted by the authors was based directly on the deep ecological attitude towards nature, which is favored and recommended by the Norwegian ecologist as a starting point for creative searches and, as a result, for ecological successes in environmental design. The strategies that have been applied in the education of students are based on two fundamental principles of deep ecology: • Bioregional development, defined as development based on place. This principle is related to bottom-up activities carried out in local ecosystems. Ultimately, these actions have an impact on the long-term global effect.

•
The Norwegian friluftsliv principle, created by Arne Naess, the initiator of the philosophy of deep ecology, is defined as the joy of identification with wildlife. This principle was creatively developed by Nils Faarlund into the idea of introducing wild ecosystems to cities in the form of forest and park greenery-Ecological Education Parks and creating green eco-architecture on the outskirts of cities. New ecostructures can provide direct contact with wildlife and ecological education for city dwellers without leaving their place of residence. They also shape a zone with a new spatial organization and a different audiosphere that fits into the sound ecology [4][5][6][7][8][9].
Moreover, the methodology of the research conducted by the authors was based on contemporary concepts of sustainable development and ethics of responsibility. Sustainable development should not be viewed as a fashion, necessity, and complication, but rather as an opportunity to anticipate and prepare for the future. The awareness of the need to respect and protect lasting values as well as the will to act in a sustainable way and to engage in practical, rational contribution to sustainable environmental development gives a sense of responsibility for the lives of future generations [10,11]. The ethics of responsibility of the German philosopher Hans Jonas is most often treated as consistent with the ethics of sustainable development. Technological progress has increased the reach of human activity to such an extent that it requires a new philosophy of responsibility in the approach to dealing with new technologies, and above all, "disruptive innovations". He formulated the ecological imperative "Act so that the effects of your action are compatible with the permanence of genuine human life" ("Act not destructively for future generations and the totality of their life conditions")-Be aware of the responsibility for the consequences of their own actions [12]. In this sense, the understanding of sustainable development is about being able to rationally meet the needs of the present and at the same time maintain a healthy, safe, and ready-to-exist environment for future generations. In architecture, as in other areas of our life, sustainable development is not only ecology, but also social, economic, psychological, and cultural factors that determine the health, safety, comfort, and social interaction of individual users. Sustainable development implies a holistic view of the ecological, economic, and social impact of technology and the material environment on humans and nature [10,11,13,14]. Designing ecological and sustainable architecture includes holistic, multi-directional activities ensuring optimal use conditions, including health, hygienic, and aesthetic conditions, with minimal interference in the natural environment and low consumption of natural resources. The main goal of sustainable design is to maintain harmonious relations in the system: user-building-natural environment.
The basic characteristics of "green buildings" and their eco-equipment are functionality, efficiency, and environmentally-friendly operation and processes, including rational and effective management of water, energy, and materials [15].
Sustainable development in architecture concerns the materials, devices, installations, and equipment used in buildings, their sustainable design, construction, and production methods that enable their sustainable use. It means: • taking into account the shape, orientation, and surroundings of the building in the design [13,[16][17][18], • the use of an optimal body of the building [17,18] taking into account the entire life cycle of the building, all phases of its existence-from design to possible demolition of the building and recycling of materials [24,25], • taking into account the impact of the building on the environment at every stage of its construction and operation [11,13,24,25], • the use of materials with zero and reduced carbon footprint, carbon-negative materials [26], • taking into account the circular economy in architecture and construction-an economy model that already at the stage of assumptions and design provides for the circulation of materials: biological, designed so that their waste can be safely reintroduced into the biosphere; technical materials intended for marketing in high quality and processed so as not to harm nature [27], • the use of high-quality durable solutions that will last for a long time in good condition [10,14,20], • the use of proven, timeless solutions [10,14,20], • ensuring the possibility of uncomplicated maintenance of the building in good operational and aesthetic condition, without the need for frequent repairs and changes [10,11,13,14].
The constant search for optimal solutions to balance architecture and nature turns out not to be a matter of coincidence. This is determined in advance, right from the start, at the planning stage [10].

Aims and Scope
The article presents the methodology and methods of implementing the assumptions of deep ecology and sustainability in practice in academic teaching as part of the courses:

•
Habitats-the context of place. • Architecture design. Research and design studio: Environmentally-friendly dwelling architecture.

•
Interior design. The above courses are conducted by the authors for 1st and 2nd degree students at the Faculty of Architecture of Wrocław University of Science and Technology. The aim of this education is to show that a deeply ecological attitude seems to be a means of identifying the reasons and eliminating the ecological crisis. The paper indicates the following educational principles and methods, developed on the basis of the theoretical and practical knowledge of the authors in the field of architectural design and their teaching and research experience:

•
Educational method of four-stage work on the ecological design concept.

•
The principles of shaping environmentally-friendly architecture.

•
The method of assessing effectiveness and purposefulness of the research on the deep ecology process within the subject courses.

•
The survey method as a didactic and scientific experiment and didactic tool.
The main purpose of the article is to show how the courses conducted by the author at two different consecutive stages of educating students (stage I: Habitats-the context of place, stage II: Architecture design. Research and design studio: Environmentally-friendly dwelling architecture and Interior design, being an element of the education of architectural engineers, were created as a result of scientific research on the deep ecology and sustainability process.
Another goal which was set by the authors was to demonstrate the effectiveness and quality of the courses and the rationality of the assumptions adopted for their implementation, which are a creative development of the fundamental assumptions of deep ecology: development based on place, and friluftsliv-the Norwegian tradition of identification with wild nature, which has evolved into the idea of introducing forest and park areas into cities as wild ecosystems and environmental education through practice.
Research on the purposefulness and legitimacy of the adopted rules for conducting the presented courses was developed during two consecutive semesters in the following academic years: 2019/2020 and 2020/2021.

Innovative Research Methods
Research into deep ecology covered the issues which were connected with the development of eco-housing complexes on the basis of the environmental and cultural context of the place, with an emphasis on interdisciplinary pre-design studies on the localization of developed topics. They constitute an extension of the three of the basic principles of deep ecology, defined as: development based on the place, friluftsliv, and environmental education through practice. The method consisted of the appropriate and careful selection of the location of areas covered by the development prepared by students, mainly in terms of the vicinity of forest and park areas intended for transformation into Ecological Education Parks and the possibility of deliberate adaptation of adjacent building plots for functions accompanying residential areas, such as forest kindergartens, eco-educational sensory pavilions, ecological education centers, recycling centers, and urban crops with street food. An analysis of the resulting concepts was applied. Then, a selection of the issues, which served as the fundamental basis for both courses, was subjected to a critical analysis. The courses were created by the method of synthesizing elements which proved successful in practice and contributed to the effectiveness of the entire process. The following aspects were tested successively:

•
The frequency and legitimacy of the selection of the area covered by the study, depending on the vicinity of forest and park areas and the classification of the selected area, respectively: to the suburban or strictly urban zone (Method of analysis and synthesis).

•
The legitimacy of the experimental introduction of an additional innovative method of interdisciplinary research at the 2nd degree. (These were the studies of soundscape of places covered by the study to honor the ecology of sound as a significant part of the deep ecology process).

•
Purposefulness and effectiveness of interdisciplinary issues introduced into the educational process, through adequately distributed control enclosure tasks performed by students during properly distributed time (Method of analysis and synthesis and In Situ Method implemented in the form of: drawing presentations of an interdisciplinary topic and practical tasks-environmental education through practice-revitalization of public spaces within the Campus of the Faculty of Architecture of the Wrocław University of Science and Technology, e.g., box-type permaculture crops composed by students and combined with campus spaces requiring revitalization).

•
The effectiveness of the use of computer support in the field of energy efficiency simulations of designed layouts, and finally the energy balance of objects, which makes up the entire spatial composition of the study (Method of analysis-Life Cycle Assessment /LCA of buildings and carbon footprint calculation).

•
The frequency and effectiveness of students choosing a profile of topics within the scope of deep ecology. The Survey Method conducted among students (Interior design) was aimed at recognizing the general knowledge, awareness, and experiences of students connected with the topic of "green architecture", as well as examining the impact of the courses and the discussed problems on the development of their interest in the issues of ecological design.

Deep Ecology in Architectural Education
Naess' papers on deep ecology became an inspiration in architectural education. They also became the basis for research on the methodology of subject courses, setting out directions and research areas implied locally, which were closely connected with the global mainstream. However, necessary and significant changes are only possible when long-term strategies, which harmonize with nature and do not compete or fight with it, are developed. One of these strategies, which was already practiced locally in Norway by ecologist Per Ingvar Haukeland, was researched as part of the author's two subject courses. It is defined as "development based on place", which is closely connected with the renewal of the sense of place. In the context of spatial planning, it boils down to bottom-up activities, focusing on a small piece of space and trying to make remedial actions within a given area, local ecosystem, where we live and work, as well as where fundamental changes should be introduced. Following Haukeland's thought, who proposes to act according to the following principle-"We should start from the point where we are and go towards the point where we will see that our vital needs are met" [28] -as a result of the analyses and syntheses conducted within the framework of the research, the conclusions, which contributed to the creation of the presented courses, were drawn as follows:

•
Exploring how a place where social development is being tried in harmony with nature is related to what we call an ecoregion (bioregion), a natural region. • Application of place-based economics, the natural consequence of which will be local food production based on the philosophy of permaculture, diversity, and complementarity of the local ecosystem. • Skillful application of technologies which are oriented towards deeply rooted values.
These actions may concern both rural and urban areas. Ecovillages are built in the open landscape. Residential buildings, together with adjacent greenhouses, gardens, henhouses, orchards, ecological crops, pastures, as well as production and wild forests create complementary and self-sufficient eco-structures. In Norway, the whole series of such projects has been launched in recent years. The most significant are the ecovillage of Hurdal-HØL in Hurdalsenteret (implementation in 2014) as well as Grenda and Åsa in Ringerike (implementation in 2016), [29]. In the rural environment, a place-based development may also apply to activities in small groups, i.e., family and neighbors, focusing on introducing ecological solutions in these small communities, which consist in planning and using land, local green products, environmental education, e.g., by means of rural tourism or training and ecological agriculture activities [30]. In recent years, a number of ecovillages have been established throughout Poland to promote ecological education and self-sufficiency based on permaculture.
In the urban context, planning activities oscillating around Naess' thought are recently implemented projects in the field of:

•
Housing complexes maintained in the spirit of deep ecology with designed elements of a city farm (horizontal or vertical) with a focus on the following objectives: educational and local production of food/green products which meet the needs of residents (which supports self-sufficiency). They combine the reproduction of traditional landscape elements such as woodlands, balks, meadows, and pastures, small water reservoirs with exhibition and educational functions and small gastronomy, focused on the promotion of local products produced on the spot. Organic farming is based on biodiversity and permaculture. A return to grazing livestock in cities, for example goats and sheep, even for short periods, makes it possible to maintain the biodiversity of semi-natural areas and to expose valuable views. • Implementing the principle friluftsliv, which is part of Naess' philosophy of life, designed green, wild areas in a city, increasing the offer of environmental education and protecting local biodiversity and integrating the communities living in their surroundings around these activities. The following elements become important in designing such new models of ecological education parks: diversity of design solutions, participation of semi-natural vegetation, limitation of care treatments, emphasis on education, -sequence of views, landscapes, and impressions, which is formed by the mosaic layouts of habitats, -viewpoints (beauty spots) which enable observation of nature from different perspectives, -using ecological succession as a creator of modern parks or its parts.
The aim is to increase the local biodiversity by modeling succession processes and the mosaic character of plant communities. Users gain knowledge about the processes taking place, e.g., cycles in nature or ecological succession, and they can, for example, see how the vegetation changed over a period of about 10 years in the photographs [31].
A model example of green eco-architecture integrated with an ecological education park is Nansen Park on the Fornebu peninsula in Norway, created on the revitalized area of the former airport [29]. Central European examples include the development of a part of the Belgian Hobokense Polder into an ecological education park with a green housing complex called Groen Zuid in Antwerp, and Nordbahnhof Park in Germany [31].
A key task for organizations dealing with nature conservation in Poland are activities for the development of green areas in cities and their adaptation for educational purposes. At the same time, they constitute new green jobs for field educators and local leaders. Raising the standard of visiting environmentally valuable areas in cities constitutes an opportunity to attract more people interested in nature conservation and change their lifestyles to those in line with the principles of deep ecology, thus encouraging them to spend more time there. The message about the species occurring in a given place and natural processes taking place, as well as about the benefits offered by urban ecosystems to all forms of life inhabiting them without exception, is very important for local communities. Appropriately designed infrastructure in such places should minimize the impact of visitors on the ground within the area with strict protection, whereas locating environmental education centers on its outskirts will contribute to the implementation of facilities using modern and nature-friendly technologies. Tomasz Molenda, speaking to problems around the protection of anthropogenic environments in Poland, believes that damages to the natural environment resulting from urbanization processes are highly irreversible and costly if the aim is to restore a state close to the natural one. On the other hand, many researchers point to the ecological importance of the transformed natural systems and urban ecosystems to an extent that does not allow them to return to the historical state of the past. In literature, they are referred to as novel ecosystems, and in relation to cities, urban novel ecosystems. Despite the changed species composition along with the participation of native and alien species evolving without active human participation, they offer many benefits and constitute a new value [32]. Elements of urban agriculture based on permaculture and environmentally-friendly technologies integrated with housing It is particularly important to implement the analyzed subjects of ecological education through practice, e.g., permaculture crops composed by students as pocket gardens and a means of revitalizing urban space into educational programs.
The presented conclusions, which are the result of analysis and synthesis achieved in the course of the research, led to the creation of the presented courses. It is recommended that other educators use the guidelines developed by the authors.

Deep Ecology and Sustainability in Student Architectural Design
At present, Naess' philosophy of life of deep ecology is developed as part of the subject: Habitats-the context of a place for the 1st degree studies at the Faculty of Architecture of Wrocław University of Science and Technology, with continuation of the 2nd degree studies during a selectable subject under the following name: Architecture design. Research and design studio: Environmentally-friendly dwelling architecture and in the subject Interior design.
The courses are addressed to 1st and 2nd degree students who differ in the degree of experience and detailed knowledge in the field of ecological architecture. Therefore, the organization of these classes and the scope of the development of topics are varied. Stage I emphasizes one of the fundamental principles of deep ecology-bioregional development. Development based on place is intended to show the importance of bottom-up actions that ultimately influence global strategies, and to show how people, culture, and nature co-evolve over time. It is reasonable to determine the environmental potential of the area covered by the study in terms of the organization of the city farm. The measure aims to ensure self-sufficiency in terms of food production and renewable energy for the shaped architectural structures. These studies are combined with the activities of students in the field of detailed analyzes of the area and variant development of the concept in terms of the organization of spatial and social structures, supporting the self-sufficiency of housing complexes such as: cohousing, coliving, and cooperatives. Work on the design concept is carried out in groups of two students. Stage II additionally stresses the second fundamental principle of deep ecology, friluftsliv, as finding joy in identification with wildlife. Residential complexes are designed on the border with forest and park areas transformed into wild ecosystems that evolve without human participation, the so-called ecological education parks. The activities of students focus on shaping green architecture in constant interaction with wild ecosystems of parks in an open suburban landscape in the form of an ecovillage or in strictly urban landscape as green responsive architecture. The residential functions are supplemented with service, recreational, and educational functions, such as: forest kindergartens, interactive pavilions, acoustic capsules, and eco-educational bird watching towers. As part of detailing the concept, additional ecological elements are also designed. Examples are nesting boxes for birds integrated in harmony with the architecture, home composters, and permaculture boxes. The education of students also includes learning in the field of calculating the energy efficiency of buildings and the carbon footprint and estimating the size of rainwater tanks. These residential eco-structures are aimed at two important goals, i.e., educational-connected with the environmental education of users from the youngest to seniors and universal design [32], as well as agrarian-local food production based on permaculture with the possibility of breeding and grazing animals or other activities such as the organization of apiaries for bees. The studies include urban and architectural scales. Work on the design concept is carried out in groups of three students. In their basic assumption, they implement the attitude of being in the world by perceiving nature, culture, and the self as a combined whole, in accordance with the principle-placebased development. The context of a place becomes the key to the idea of foundation. First of all, the environmental and natural contexts are taken into account and then the cultural context. These assumptions are in most cases of an application nature and fit into the urban novel ecosystems trend. These projects, both in terms of ideas and implementation, are an attempt at responding to the deepening climate and ecological crises. The work on the design concept: Habitats-the context of a place (2019/2020), Architecture design. Research and design studio: Environmentally-friendly dwelling architecture (2020/2021) was divided into several stages, which were evaluated (Table 1).  The concept of landscape planning of the area covered by the study-formation of an eco-structure-a residential environment integrally synchronized with the elements of a city farm, i.e., horizontal or vertical, wild or social gardens, apiaries and meadows, giving animals the possibility to graze, e.g., goats or sheep (1st and 2nd degree studies) and wild ecosystems-ecological education parks in the suburban (ecovillages) and in strictly urban zones (green responsive architecture) associated with eco-services, such as forest kindergartens, small gastronomy based on local consumption and sales, ecological products produced on site, architectural elements for eco-education (2nd degree studies). The overall concept takes into account the principles of universal design, which includes the needs of the elderly and the disabled [33]. The criteria for assessing Interior design 2019/2020 course were established on the basis of the available knowledge and previous experience in the field of "green architecture" and ecological design. The above actions became the basis for developing the principles of shaping environmentally-friendly architecture:

1.
Nature as a source of associations and inspirations in architecture (miracles of nature, hydrological, geological, and astronomical phenomena, discoveries in biophysics and astrophysics, etc. as inspirations, imitating nature, using nature patterns and bionics-biomimicry).

2.
Integration of architecture and landscape as well as combination of a building with the surrounding context.

5.
The use of symbolism connected with nature as a way of integrating architecture into the cultural and nature context. 6.
Combination of nature and art. 7.
Combination of environmentally-friendly technology, saving natural resources and aesthetic value. 8.
Treating components of environmentally-friendly technologies as artistic matter and showing their connections with nature, life, and the symbolism of the building. 9.
The use of materials which are recyclable and undergo restoration. 10. The use of energy-saving materials (production cycle-transport, processing, life cycle). 11. Harvesting indigenous materials (e.g., using native wood). 12. Storage and economical water management. 13. Low exploitation costs. 14. Re-use of existing buildings. 15. Reducing the use of chemicals which deplete ozone and affect health. 16. Efficient use of energy. 17. Passive daylight strategies [42]. 18. Biodynamic lighting strategies in daylighting and tunable lighting [42,43]. 19. Optimization of acoustic solutions as protection of human health and the sound landscape [44]. 20. Orientation in relation to the directions of the world.

"Green Architecture" or Ecological Design-the questionnaire for students
Taking into account the criteria adopted in order to evaluate Interior design course, the course which was conducted in the years 2019/2020 was assessed. The evaluation shows that 20% of students participating in the Interior design course 2019/2020 chose design topics in the scope of "green architecture" and applied the principles of shaping environmentally-friendly architecture and used clear elements of ecological and biophilic design in their projects.
The evaluation of the course became the basis for preparing a questionnaire-a didactic and scientific experiment aimed at increasing interest among students in the subject of "green architecture" and ecological design. The Survey Method conducted among students (Interior design) was aimed at recognizing the general knowledge, awareness, and experiences of students connected with the topic of "green architecture" as well as examining the impact of the courses and the discussed problems on the development of their interest in the issues of ecological design.
At the beginning of the design classes, presentations on contemporary trends in interior design with a clear emphasis on the principles of shaping environmentally-friendly architecture, the features of "green architecture" and biophilic design, as well as sustainable development in architecture were conducted for students. The survey was conducted among students participating in the Interior design course 2020/2021 in the middle of the semester (the course duration is 15 weeks) instead of delivering the intermediate project, which had been so far practiced within the framework of the course.
The survey method was prepared in the form of 10 questions, one of which was illustrated. The following questions were part of the questionnaire:

1.

3.
Have you had the opportunity to use an interior with ecological solutions?
No. -I do not know, maybe.

4.
If you answered "yes" to the previous question, indicate the type of ecological interior that you used.
Indicate the benefit resulting from ecological design that you consider the most important.
-Protection of the natural environment.

6.
In your opinion, which of the following concepts is the best example of "green architecture"?

Do you feel encouraged to green design in the future? Partially.

If yes, what is special inspiration for you?
-Fashion and trends in contemporary architecture (e.g., biophilic design).  (Table 3) the students were asked which of the images they found most inspiring to take up the topic of "green architecture" and ecological design.

Discussion of the survey results:
How to shape the environment which was built in harmony with nature and aesthetics? The answer may be the search and determination of new directions of "green architecture", which is a combination of nature, art, and technology, as well as the creation of beautiful and friendly spaces for societies which increasingly need contact with nature.
If architecture as a shelter for humans is not detached from the broad environmental context, then designing an ecologically and socially safe future may turn out to be feasible. It is extremely important to sensitize students of architecture as future creators of our surroundings to the above-mentioned aspects. What is their knowledge, awareness, and experience connected with the topic of "green architecture"? Are the issues discussed by the lecturers and is the way of conducting classes inspiring and encouraging to ecological designing? Do they contribute to the development of students' interest in the topics of "green architecture" and biophilic design? These and other questions appeared in the questionnaire, which was one of the scientific methods applied in our research. The questionnaire was completed by 66 students-participants of the courses conducted by the authors. The following criteria were considered by students to be the most important in ecological design: the use of technologies which provide the rational and economical use of natural resources (87.9% of responses), the use of recycled materials (75.8% of responses), the use of solutions ensuring health and well-being of users (53.0% of responses). Overall, 97.0% of the students participating in the survey admitted that they had an opportunity to learn the principles of ecological design at previous courses (37.9% fully, 59.1% partially). Only 52% of the respondents confirmed that they used the interior in which ecological solutions were applied. Among the functions mentioned, there appeared residential (32.4%), gastronomic (35.3%), commercial (35.3%), office (5.9%), as well as hygienic and sanitary functions (public toilet), (2.9%). Most students (73.8%) consider environmental protection to be the most important benefit resulting from ecological design. Other benefits include living in harmony with nature (16.9%) and health and well-being of users (7.7%). On the other hand, no one indicated financial savings as a benefit. The concept of a house with water and energy saving solutions was recognized as the best example of "green architecture" (75.8% of responses). There were also responses aimed at the use of recycled materials (19.7%). The entire group of students participating in the study felt encouraged to incorporate green design in the future (89.4% full and 10.6% partially). The most important inspiration turns out to be foreseeing and forward-thinking about future generations (60.6%). Other motivations include worldview, beliefs, lifestyle (25.8%), technological progress, and innovation (6.1%), fashion, and trends in contemporary architecture (3.0%). The knowledge shared by the course instructors aroused interest in the subject of "green architecture" among the majority of students (48.5% fully, 50.0% partially).
Encouragingly, most students consider environmental protection to be the most important benefit of green design. It is interesting that no one has indicated financial savings as a benefit, but this topic is also important-this result can be significant for improving the course and developing students' awareness in this aspect as well.
The last question contained 5 examples of architecture in different ecological contexts ( Table 3). The students were asked which of the images they found most inspiring to take up the topic of "green architecture" and ecological design. Table 3.

The research additionally compared the projects made as part of the Interior design 2019/2020 and Interior design 2020/2021 courses, taking into account ecological criteria, which made it possible to check and confirm the purposefulness and effectiveness of the presentation covering the principles of shaping environmentally-friendly architecture, features of "green architecture" and biophilic design, as well as sustainable development in architecture (a lecture opening design classes), and a mid-course survey as a didactic method to encourage students to take up the topics of "green architecture" and ecological design.
The evaluation shows that 80% of students participating in the Interior design course 2020/2021 chose design topics in the scope of "green architecture" and applied the principles of shaping environmentally-friendly architecture and used clear elements of ecological and biophilic design in their projects. This is 60% more than in the previous year.

Conclusions
Our research showed the effectiveness and high quality of the courses tested, as well as the rationality of the assumptions adopted for their implementation. The adopted methodology may be used by other educators in applying the guidelines developed by the authors.
The introduction of design strategies in the field of deep ecology in architectural education will allow us to look at nature not as something outside, but it will allow us to learn that all life forms are its integral part and are of great value. This is connected with the application of the educational system already from the pre-school level in the place of residence (e.g., by means of ecovillages, urban housing eco-structures), up to adult education, with an emphasis on direct, practical academic education, and thanks to friluftsliv-education in wild nature and municipal ecological parks designed for this purpose. Introducing changes for a deeply ecological future should include bottom-up actions, even though it will be of global character. What we need is striving to be the driving force where one lives, to achieve a more bioregional development, where the interdependence between nature, culture, and people co-evolve in a lasting and longterm way.
The use of the innovative research and education methods turns out to be an effective way of teaching sustainable and responsible architectural design. It gives extensive opportunities to consider advanced, so-far unproven technological and material solutions at the stage of student design concepts implemented as part of courses conducted by experienced architects who are academic teachers and researchers. It enables insightful observations and analyzes of the advantages and disadvantages of the adopted design assumptions and considered design solutions in the context of future implementations. This is done without any financial loss or negative user experience.
Intensive research and design cooperation between students and teachers in architectural faculties is a way to fulfill dreams of living in a harmonious relationship between users, buildings, and the natural environment. It was noticed that only the method of project cooperation, where both the student and the tutor feel responsible for the entire project process and its effects, may bring benefits in the future. Not only the transfer of knowledge about ecological architecture, but most of all reliable cooperation, can encourage students to adopt the idea of sustainable and responsible design into practical activities.
In addition to the conclusions of this work, an attempt was made to solve the problem of combining the necessary teaching and interdisciplinary research at universities of architecture, indicating the research through design (RTD) methodology as an effective method for real innovations in ecological and sustainable design. RTD method involves the inclusion of design activities in the research process and the use of design to acquire new quality knowledge, including knowledge about sustainable development. The RTD methodology can be helpful in discovering completely new solutions and introducing innovations in all areas of design, including architecture and interior design. Moreover, it can change the nature of everyday contact with technology and reduce the negative effects of digitizing life. By creating prototypes, patterns, sample projects, and unfinished products, it is possible to explore potential opportunities and innovations without large and risky investments [46]. For this reason, the RTD method could be extremely useful and effective in the area of teaching architectural design. Innovative design solutions focused on sustainable development in architecture can be recognized, analyzed, and verified already at the stage of student projects.
The RTD method can be used as a clear and effective teaching strategy for architectural design. The RTD method is productive in design education as it keeps students and teachers in a continuous loop of cognitive, creative, and reflection action, and emphasizes the value of theoretical concepts in understanding practice [47]. Theoretical concepts developed in design courses become a resource of knowledge and skills from which students can draw preparation for design practice, resulting from an understanding of the need to integrate theory and practice in architectural design.
