1. Introduction
Airport terminals are one of the most emblematic building types of architecture that represent the new global wave of building types. Showing off their economic prowess and adaptability to human factors, novel building technology, and vibrant engaging user experience have eclipsed their design character as they are more inclined toward globalization and less associated with the cultural identity of the city they belong to, forgetting that the airport terminals are, as Dr. Rim Zougheib describes it, play a crucial role in shaping a city’s identity and image [
1]. Examples of such airport terminals that are considered global international transit spaces are the airports of Singapore and Qatar. In this increasingly competitive industry, airports have recently started to actively promote customer retention and long-term success by aiming for customers to have positive opinions and attitudes while in the airport, feel involved with the airport, and have good psychological well-being there [
2].
Massey believes that airports have a “global sense of space” [
3] since they attract a diverse range of individuals with varying backgrounds, personalities, and travel destinations, encompassing places for work, trade, retail, recreation, communal areas, and logistics. Despite their symbolic nature, many airports are considered prime examples of “placelessness” as they have no special relationship with the places in which they are located, as stated by Edward Relph in his seminal “Place and Placelessness” [
4]. Instead of designing a space standing for a certain culture, airport designers have created spaces that can stand as the background for any nationality. This could be changed by introducing identity features to the building, creating a “place” that is a great iconic representative of its location to become a narrative cultural “place” within its setting.
Saudi Arabia covers the vast majority of the Arabian Peninsula and includes various regions that are characterized by distinct landscapes, topographies, and architecture. As a result, its architectural heritage is extensive and varied. Economic and regional shifts during the late 1960s and early 1970s had a significant impact on Saudi Arabian architecture. This change was because of the increase in oil prices in the 1970s, which allowed the Saudi government to establish a strong, centralized administrative structure based mostly on oil revenue [
5]. Recently, it has become one of the Middle East’s fastest-growing countries, changing the building industry and urban planning, as a number of massive projects are underway that will completely reshape the country and revitalize various cities and districts, including historic ones with rich cultural history and empty spaces [
6].
However, it is crucial to follow humanitarian architecture as it plays a significant role in establishing a balance between development and authenticity because of its dual roles as a guide for reconstruction and an agent of sustainable urban planning [
7]. Modern Saudi cities have emerged quickly, paying little attention to the socio-cultural norms that shape their behaviors and create the country’s traditional built environment [
8]. This situation has created a gap between modernity and tradition. In accordance, the central government has suitably increased its supervision and involvement and provided more political backing in areas like the construction of environmental infrastructure, environmental monitoring facilities, and inspection methods. Saudi Arabia has become steadfastly dedicated to preserving its rich cultural legacy while looking to the future. That is why incorporating traditional Arabian architecture into modern design is a key component of Vision 2030 [
9]. The Saudi government has attempted to influence the architectural style of massive new governmental and public architectural projects, such as the Ministry of Interior, the Ministry of Foreign Affairs, airport terminals, railway stations, central libraries, and office buildings, creating new contemporary hybrid models of architecture, resulting in a unique glocal architectural language carrying Saudi identity inspired from the traditional architecture but with a modern flavor,
Figure 1,
Figure 2 and
Figure 3.
An organization, the Saudi Heritage Commission, was established to fulfil Saudi’s 2030 vision concerning the preservation and promotion of the unique cultural heritage of Saudi Arabia. The Commission has fostered a sense of identity and belonging among local populations [
10]. In an effort to balance the past and present and serve as a global source of inspiration for architectural innovation, current Saudi architecture aims to combine modern design with historical references to improve the urban landscape and quality of life [
11]. Such a commission is important as it is believed that innovation in industrial and building technologies can be fueled by improvement in environmental regulation requirements [
12]. In its new designs for transportation terminals, Saudi Arabia ensures the promotion of powerful identity characters that connect them to their contexts, backgrounds, and people.
1.1. Architectural Identity vs. Globalization in Airport Terminals
Due to the progression in urban homogenization, where local character falls victim to global styles and materials, globalization has had a significant impact on architecture. This impact eliminates regional architecture in favor of standardized functionality and efficiency over cultural identity [
13]. However, local architecture is an important element that reflects cultural identity and creates a sense of place. Identity defines and distinguishes an object from other things. It works both ways, using certain characteristics, carrying the meaning of existence as Paul Brislin explains it, “… there is no doubt that a sense of identity is essential to survival—of individual, family, group and neighborhood” [
14]. This means that identity is not only concerned with individuals but extends to define societies, countries, and whole regions. This shows that the identity notion is a complex issue that is present naturally, even if not summoned or recalled, as it gives a sense of attachment and belonging. Since identity is a representative of people, their culture, their lives, and their politics as Hamid and others clarify, “Identity is a complex issue because it stems from numerous determinants such as those from social and political order” [
15] and since people and their societies are changing, identity therefore exists naturally and is always evolving as people inevitably change as a reaction to certain external stimuli. Martin Heidegger states that people should keep looking for a sense of belonging in any space through its architecture and urban setting, providing it with a sense of place [
16]. A space turns into a place through the cultural, physical, and emotional value that it gains through past experiences [
17]. Therefore, identity is a crucial component in creating interaction between a place and its users and promoting the entire context. Although globalized buildings succeed in making a statement and fostering the latest technological trends and attributes, they ultimately seem disconnected from the local identity, losing the distinctive personality and resulting in a sense of similarity, which is one of the drawbacks of globalization.
Consequently, identity and globalization are two opposing forces. There will always be exchange, attraction, and conflict between any two opposite forces, regardless of how powerful they may be [
18]. Thus, architectural identity and globalization are and will always be competing forces that have to co-exist side by side, implying that creating hybrid models that boost both identity and globalized features in a glocal atmosphere is the most effective combination for public spaces,

Some places are characterized by being global, having a chaotic picture of different and opposing identities. Every major city around the world has developed airports as hubs for international transition and people flow, which is an iconic illustration of globalization. All global characteristics have drawn on the features of airports such as the used technology, leisure features, displaying and selling of consumer products, or even basic features of the architectural design. Airports can be referred to as “places of Globalisation” that are defined, or are at least heavily influenced, by the contemporary emphasis on leisure, consumption, and global mobility [
19]. The functionality of the architectural design of airports and their environments has been fueled by globalization. Decision-makers are more concerned with achieving the desired visual impression by following the design idea or budget than they are with using local elements. Users have become disengaged from the built environment as a result of this homogeneity, which has produced similar physical places. Globalization has affected airports’ architecture, producing new appearances resulting from the blending of cultures and the disengagement from tradition, context, and, frequently, cultural origins [
20]. Globalization and changing societal dynamics have led to a loss of “sense of place”, identity, and continuity in architectural development [
21]. Consequently, global ideas are perceived as a threat to locals. The sense of ‘place’ is on the verge of disappearing due to external factors outside the control of its inhabitants. A global space’s globality is not negated by the addition of identity features; on the contrary, it is enhanced, and it adds to the value of the space, setting a special spirit for it [
22]. The issue of “Identity vs. Globalization” could be considered a contemporary version of the case of place and placelessness raised by Edward Relph. Relph concentrates on people’s identities concerning their location while analyzing place in depth. Peng, et al. state that the process by which a person is evaluated is a representation of social and cultural interactions, which is the impact a location has on a person’s identity [
23]. Auge also differentiated between a place and a mere space through the existence of identity, calling it a place and a non-place [
24].
Therefore, global architecture could have some identity features that characterizes it without losing its globality and provide some attachment to its users for an authentic experience. At the same time, identity does not imply a return to the past and a lack of use of modern tools and technology. It is challenging to meet the cultural needs of all airports’ users due to their diverse backgrounds, but it is more important to adopt the local identity of the airport’s host city as a means of cultural empowerment.
In terms of culture, airports could be viewed as spaces in-between, between a traveler’s home culture and a new one, or between two distinct cultures depending on the traveler’s point of departure and their destination. Passengers’ emotions vary between stress, excitement, nostalgia, anxiety, fatigue, and indifference. Introducing the architectural and arts cultural elements of the airport’s host country may have an instrumental role in attracting passengers’ attention, fostering cultural passion, and elevating their trips to a higher intellectual level. Airports stand as ambassadors of their countries to create a lasting impression of unique identity on travelers. The absence of this fingerprint leaves the airport as a non-place with no meaning and without an architectural impact on the user. It is well known that users’ behaviors differ in aeronautical spaces (e.g., boarding, check-in, and security) compared to non-aeronautical services (e.g., retail services, food courts, or booths and waiting lounges). These non-aeronautical spaces could be described as consumer spaces that attract travelers with their globalized features and should be looked at as fertile land for introducing the local culture to all travelers for the first time as a welcoming gesture and an advertising plan for more touristic impact. The architect should take advantage of the waiting time of the passengers, after the stress of completing traveling procedures, to involve them in a deeper cultural experience. It is one of the most essential responsibilities of architects to create experiences in space [
25]. Benefitting from the waiting time in airport terminals can add a deep dimension to the traveling journey, creating interaction, memories, and place attachment. To engage passengers, relieve them from stress, and enhance their experience, easy and well-designed way-finding systems for ease of access and interior settings that deal intellectually with the passengers’ minds, attract their attention, increase their knowledge, and satisfy their curiosity are needed.
1.2. Identity Indicator Design Characteristics in Airport Terminals
Recognizing architectural identity is a multifaceted responsibility. Methods of detecting it are different according to the scale of the user experience, whether on a planning and urban scale, architectural scale, or interior scale. Airports provide a unique user experience that is distinct from any other space due to the nature of the mood and attitude of the users while they are in the airport. Kim et al. concluded that waiting and screening times evoke negative emotional responses [
26]. Tiredness and rapidity in transferring from one hall to the other and the willingness to complete all traveling procedures deprive travelers of enjoying many spaces in the airport. The majority of travelers do not perceive the mass design of the airport or understand the intention of its designers. In addition to the ease of functionality and speediness in circulation, the morphological attributes of the airport are supposed to have a psychological impact on passengers by relieving their tension and boredom. Designing the identity features of the airport’s host country introduces a new dimension (twist) in experiencing the airport as a ‘place’ instead of being an area in between, putting the airport spaces as a vital milestone in the journey’s route. Whether the airport is a starting point in the journey, a transitional space, or a destination, local identity features open an interesting, informative, and critique-friendly path in the passenger’s journey, creating a moment of psychological relaxation and promoting cultural exchange. Different scholarly reviews discuss how identity elements should be used to deliver their message and meaning in different spaces. Alavi & Tanaka state that “Identity” is shaped by a variety of cultural, historical, social, economic, and environmental factors. Every community’s architecture contributes to clarifying its identity since it conveys its ideas, messages, and unique characteristics. A building’s form, materials, details, façades, history, and cultural references are a few examples of this [
27]. Ali et al. state that place identity can be conceived through forms, images, and activities. They explain that people’s emotional impressions and reactions extracted from architectural expressions are important to understanding the spirit and essence of places [
28]. Mahdavinejad and Saadatjoo added some other parameters that contribute to showing architectural identity, such as the construction technology and the relationship with the surroundings [
29]. Many other scholars, such as Torabi and Berahman [
30] and others have accentuated the importance of the surrounding context as an important parameter in sensing the architectural identity. Yücel & ArabacioĞlu elaborated more on the different categories of contextual impact on architectural identity, stating that physical context, sociocultural context, and local context all collaborate to shape place identity. They showed how defining contextuality as either cultural or physical is inconsistent [
31]. Other scholars believe that social interactions, whether they are cultural, political, or economic, are vital as identity indicators [
28]. Others have divided identity indicators into formal appearance, physical settings, and natural givens [
22,
32]. Khaznadar and Baper proposed a model that combines two opposing viewpoints to describe identity as a continuous process. The first asserts that architectural identity is the one passed down through the generations, whereas the second believes that new technology and scientific discoveries can create architectural identity [
33]. Accordingly, identity indicators can be discussed from many perspectives according to the intentions and points of view of the researchers, while in the case of airport terminals and due to their specific nature, the constant reality perceived by its users is the intention of the architect that designed the airport, and the elements they used to express their ideas. Architectural expression elements are embodied in both the exterior appearance and interior settings of the airport.
In the case of airport terminals, demonstrating local identity needs a specific framework of indicators as it depends mainly on the mood of the passengers and their circulation flow in the spaces. Passengers might perceive the layout of the airport from the airplane or notice parts of the façade according to the portals from which they are entering or leaving. However, the interior settings should offer the most engaging user experience because travelers spend most of their time at airport terminals indoors. Enhancing passengers’ journeys in the airport with a cultural dimension will, unquestionably, elevate the travelers’ user experiences.
According to Patil & Raj, airport terminals serve as a city’s first image and symbolize it. As a result, the form and function of terminal buildings are as equally important as planning and architectural considerations [
34]. Airports are considered miniature cities including multiple functions where different people with various backgrounds meet, communicate, and interact with each other. The huge areas of airport terminals, the large numbers of passengers who visit and interact with the terminals every day, and the numerous functions, whether hosted by different spaces or by the unique and complex infrastructure, convert the building into a functional hub and allow it to be dealt with as urban space that needs placemaking to elevate passengers’ experiences to new heights. Designing a quality space and transforming it into a place helps passengers to feel less stressed and attracts more customers to commercial spaces, forming a kind of connection between the passengers and the transformed places. By valuing the uniqueness of the identity, celebrating the differences, eliminating the inauthenticity of globalism, and engaging with local cultures, a new place is created. Fred Kent identified the benefit of turning spaces into places as converting them into a place that you want to stay in instead of a space that you cannot wait to get through [
35]. This will turn the spaces into livable places where social interactions are enhanced and the well-being of users is improved [
36].
3. Questionnaire Results and Analysis
A structured questionnaire was developed to understand travelers’ perceptions of identity indicators in the predetermined airport terminals. These perceptions include their experiences, emotions, and vision for development to create a sense of interaction with space. The questionnaire aims to establish if the identity indicators in the different airports were noticed by the travelers, their experiences and emotions when seeing them, and their impacts on the travelers’ sense of the space, leading it to be redefined as a place. The structured questionnaire was initially tested on 10 respondents as a pilot study to find out if it was clear enough and well understood and if it needed any modifications, especially since it was intended to be self-administrated. Hence, the structured, self-administered, web-based questionnaire with multiple-choice and rating scale questions was distributed digitally. The questionnaire was deactivated after receiving 100 online responses. It included four sections. The first was the demographic questions section. The demographics of the respondents are shown in the table below,

Respondents’ Demographics |
---|
Age | 20–30 | 30–40 | 40–50 | 50–60 | Above 60 |
Percentage (%) | 20 | 43 | 18 | 13 | 6 |
Gender (%) | Male 38% | Female 62% | | | |
Nationality (%) | Saudi 81% | Non-Saudi 19% | | | |
Frequency of Travel | Once/year 4% | Twice/year 57% | Three or more times/year 39% | | |
The second section included questions about the experiences in airports in general. It was important to know the overall emotional atmosphere of being in an airport terminal, which was noted as either very positive or positive with a total percentage of 76%,
Figure 31. This indicates that airport terminals are spaces that have an impact on their users and that they are eligible to be elevated into places. Passengers have different feelings in the airport according to the zone they are present in. In aeronautical spaces, passengers’ feelings varied between excitement (61%) and stress (72%), while their feelings in the non-aeronautical spaces varied between curiosity (48%) and excitement (34%) or indifference (28%), as shown in
Figure 32. This indicates that non-aeronautical spaces, which include the consumer spaces such as waiting lounges, duty-free shops, retail, food courts, and food booths, are the spaces where passengers will need something to change the mood of their trips away from the stress they felt in aeronautical spaces.

Most participants (95%) believed that the architectural design of the airport terminal has an effect and can change the passenger’s mood and experience,
Figure 33. They even agree (96%) that an airport terminal is an appropriate medium to introduce the cultural identity of the host country to its travelers,
Figure 34, and that it influences the passenger’s perception of the host country significantly (52%) or mildly (47%),
Figure 35, and that they will be significantly interested (51%) or somewhat interested (40%) in exploring the cultural identity of the host country after seeing it in its airports,

When the participants were asked about the spaces that would grab their attention when assessing identity indicators in the airport, most participants in the questionnaire (89%) stated that the overall design of the airport would grab their attention, followed by the waiting lounges (86%),
Figure 37. When asked about the respondents’ feelings when perceiving the Saudi identity indicators in the airport terminals, their feelings varied between attachment to the place (79%), nostalgia (49%), and peacefulness (38%) among other feelings such as pride, sense of belonging and happiness for the impression the tourist gets from perceiving such indicators,

For another question about whether the presence of identity indicators makes the respondent more attached to the place, the answers were ‘yes, significantly’ (49%) and ‘yes, somewhat’ (44%),
Figure 39. This shows how effective identity indicator elements can contribute to developing a sense of attachment to the space, which indicates the readiness of the respondents to interact with it. The respondents chose the ‘Interior Settings’ (Symbolic Patterns and Motifs—Materials’ Colors and Artificial Light—Furniture and Artwork) to be the highest impactful identity indicators (90%) and the ‘Architecture’ (Concept—Mass Form—Exterior Façade—Structural Elements) to be the second influential indicator with (82%) of the respondents choosing it, followed by landscape (Courts—Interior Landscape and Greenery) (79%), and natural light (67%). Other indicators were the sign systems, the sound of internal microphones, and the local food booths, shown in
Figure 40.

In the third section, specific questions about the four pre-set case studies were asked, starting with whether the identity indicators were noticed or not and if they had any impact on the respondents. The answers were reported as shown in
Figure 41, revealing that they were noticed by the majority and had different levels of impact on them. King Khalid Airport came as the highest in noticing the identity indicators and the impact on the respondents, followed by King Fahad Airport. PMAIA’s identity indicators were noticed by 67% of the respondents but had an impact on fewer respondents. This might be due to the presence of the abstracted palms as columns at the entrance façade and then the disappearance of other identity indicators throughout the journey inside the airport. The identity indicators in KAIA were noticed by fewer respondents than any other airport in the study. This might be due to the coastal identity indicators that were used, such as the aquarium, printed waves on glass, white inclined branched columns, and landscape, which were seen as globalized features that do not refer to Jeddah only.

Identity Indicators in King Khaled International Airport (KKIA) as Previously Analyzed |
---|
Architectural Intent | Concept | Inspired by the oasis in the desert, palm trees, and Najdi traditional architecture. |
Mass Form | Geometrical triangular and hexagonal patterns with arches create the mass form. |
Exterior Façades | Glass façades connect the exteriors with the interiors with no identity references except the multi-level ceiling that continues to shape the façades’ morphology. |
Structural Elements | Multi-level roof with triangular openings as a clerestory creating an abstracted palm tree in the interior. |
Interior Settings | Symbolic Patterns | Triangular openings and floor tiling are inspired by traditional Najdi architecture. The arched multi-level roof alludes to the abstracted palm as a contextual identity. |
Materials’ Color and Light | The impression of sitting in an oasis with light penetrating through the shade of palm tree leaves is created by the multi-level roof. The interior materials’ beige tones enhance the sense of sandy dunes. |
Interior Landscape | Fountains and flower boxes in Islamic geometric patterns. |
Artwork | Traditional Najdi paintings and calligraphy. |
In King Khalid international Airport (KKIA), and according to the questionnaire response analysis, the architectural concept was the most apparent indicator to the respondents; the mass’s identity was less clear as it was not perceived by many of them, but the façades were more apparent, and the interpretation of the concept in the columns and ceiling was the most recognized. The patterns and motifs were the most impactful interior elements, followed by the materials’ colors and artificial light. The landscape was less significant than expected due to its presence at the entrance of the airport, where excitement, stress, and confusion were the most dominant feelings among passengers, as shown in
Figure 42.

---|
Architectural Design | Concept | The airport prioritizes functionality with a blend of Islamic architectural features and sleek modern façades representing Saudi Arabia’s history and aspirations for modernization. |
Mass Form | The mass has no distinct identity feature except for the dome and the two octagonal skylights that cannot be perceived from the outside. |
Exterior Façades | Sleek glass façade with a large canopy held with columns that branch into four branches forming arches as an arcade that welcomes cars in front of the building. |
Structural Elements | Columns at the façade with four beams act as branches connecting the exterior with the interior. Other columns in the interior are simple with no identity characteristics. |
Interior Settings | Symbolic patterns | Floor tiling cuts are inspired by traditional Islamic architecture. |
Materials’ color and light | Hues of beige color in marble refer to desert colors and natural stone. Floor tiling cut into Islamic geometric patterns. No natural light is perceived inside the airport due to its huge size. |
Interior Landscape | Fountains and flower boxes in Islamic geometric patterns. |
Artwork | Traditional Islamic paintings, carpet colors and drawings, mosaics, and calligraphy designed by local artists. |
According to the response to the questionnaire analysis, in King Fahad International Airport (KFIA), the architectural concept as an identity indicator was not as impactful for the respondents as expected. The exterior façades are perceived more than the mass. The most significant identity indicator was the symbolic patterns, most of which are present in the non-aeronautical spaces. Despite the huge fountain and greenery with the Islamic pattern implying the conceptual identity of the terminal, it was not recognized by the respondents. This might be due to its presence at the entrance of the airport in the excitement, stress, and confusion zone,

---|
Architectural Design | Concept | The airport’s main concept was creating a merge between the Islamic geometric patterns and the palm tree fields, recognizing the city’s landscape. This led to the design of columns resembling palm trees in abstract geometric patterns. |
Mass Form | The mass is a clear rectangle with a flat roof and glass façades. |
Exterior Façades | Sleek glass façade with a large canopy held with abstracted palm columns. |
Structural Elements | Columns are inspired in their design by the abstracted palm trees formed from interwoven steel bars carrying a flat roof. White steel bars and bolts are left exposed. |
Interior Settings | Symbolic Patterns | Floor tiling cuts are plain, with no figurative patterns except in few spaces. Some arches and woodwork are present in special spaces in the airport such as the international duty-free section, restaurants, or lounges. |
Materials’ Color and Light | Daylight penetrates the terminal from the glass façades enveloping the rectangular mass. Squares of artificial light between the caps of the columns give more plain light to the hall. White colors dominate the terminal interiors with a wooden brown interior bridge and patterned transparent glass. The seats are silver and metallic. |
Interior Landscape | No interior landscaping was seen. |
Artwork | Some geometrical patterned partitions are present in lounges, reflecting Islamic art. |
In Prince Mohamed bin Abdulaziz International airport (PMAIA), and according to the responses to the questionnaire, the concept is widely noticed in its implementation in the structural element. This raised the impact of both indicators followed by the natural light penetrating the ceiling between the abstracted columns integrated with the geometrical Islamic patterns holding the ceiling. Other interior identity indicators had less impact as they were marginal in the design,

Architectural Design | Concept | The airport draws its ideas from its coastal context, Islamic patterns, and Hijazi architecture in a contemporary vision. |
Mass Form | The mass is formed from four back-to-back brackets, with links in between allowing for interior spaces forming courts integrating with the mass. |
Exterior Façades | Printed glass façades. |
Structural Elements | Columns are either thick at the entrance or white, branched columns carrying layered patterned false ceilings according to the zone. |
Interior Settings | Symbolic patterns | The floor tiling has different hues of triangular patterns in gradients with solid colors. |
Materials’ Color and Light | Hues of beige and blues dominate the interiors, referring to the coastal identity of Jeddah. Light penetrates from the glass façades or from between the layered, patterned false ceiling. |
Interior Landscape | A huge aquarium acts as a focal point for all passengers to watch and grab photos beside. Regularly distributed palm trees are present in passages referring to the prevailing local greenery. |
Artwork | Traditional Islamic geometric patterns cover false ceilings, walls, and furniture. |
According tot the questionnaire analysis, in King Abdulaziz International airport (KAIA), the concept and its elements had less impact as identity indicators due to the globalized features that characterize them. The form of the mass introduced the integration of natural light from the walls and the courts with its palm trees that could be perceived from the interiors. The interior landscape, along with the symbolic patterns, were impactful when brought together,

KKIA identity indicators were more impactful in the emotional attachment than the other terminals as it has the most complete user experience in the overall design, whether in the concept, columns’ design, patterns, natural light, interior greenery, or all elements contributing to the oasis feeling intended by the designer. The abstracted palms at the entrance of PMAIA had an emotional impact on the respondents as well. The interaction with the aquarium in KAIA was the most apparent in the interaction with the indicators. This gives the impression that some identity indicators should be dynamic and ready for interaction with the passengers, not only shown. This might justify the high percentage of “no effect” that the identity indicators had in KFIA, as they were not integrated with the design or the users’ experience. Even the main greenery and fountain designed in an Islamic pattern with a skylight was not perceived due to its presence in the aeronautical space and its huge scale, making it difficult to be fully perceived and experienced,

The respondents chose the retail spaces, duty-free spaces, waiting areas, and passageways as the most favorable spaces for having an identity indicator experience,
Figure 49. This could be correlated with
Figure 37, which favors the non-aeronautical spaces over the aeronautical ones, and
Figure 32, which shows that the levels of stress and eagerness in these areas are less than in other areas, which allows passengers to enjoy their experiences.
4. Conclusions
This research verified its main hypothesis that “identity indicators can redefine spaces in airport terminals to be ‘places’ creating new user experience”. When a space in an airport terminal is described, the physical essence of the space, whether closed or open, and its functionality is explained, but its impact on its users is left out. To transform this space into a place, it has to acquire significance that gives it a personality to be recognized among other spaces. Airport terminals are fertile land ready to be transformed from a globalized ‘non-place’ into a unique representative ‘place’ of its host country by glocalizing its features, that is, presenting the identity of its host country by promoting identity indicators of its local heritage or culture with a modern flavor, in addition to the global features, keeping up with the latest cutting-edge technology in the field.
Picturing or modeling heritage elements or cultural aspects as identity indicators provides many layers of meanings to the place, creating a kind of attachment between it and the users, enabling them to engage and interact. Thereafter, the place will be recognized by its identity indicator. This recognition has many benefits, among which is acting as sustainable architectural marketing campaigns for their respective cities and countries.
Architectural identity can be represented in many forms; it can be historical or traditional or follow the identity of the context to carry the features of the location it belongs to. It can be implemented in the overall design of the terminal and its architectural concept, in interior or exterior landscape design, engraved patterns on walls or pieces of furniture, handrails or floors, hung artwork, and free-standing sculptures. In all cases, a place is created by offering a unique, impressive, and memorable experience to the user in addition to correct functionality and smooth circulation.
According to the questionnaire held to understand the impact of identity indicators on the passengers in the identified Saudi airports built throughout the interval of 40 years, the most impressive airport in terms of identity indicators was KKIA, where the entire concept mimicked the context as an oasis for tired travelers amid the desert. In KFIA, the architect tried to modernize the identity indicators, so the elements were dispersed with no fixed identity. In addition, the large area of the airport made it challenging to perceive the identity indicators as a whole. As a result, the airport lacked a main theme or direction. The abstract palm tree columns at the PMAIA’s entrance, and their continuation throughout the airport, with modular skylights positioned between the columns, established a clear and prominent concept that users could understand and provided the terminal with a distinctive identity. As for KAIA, the study showed that the coastal identity was not recognized as an identity indicator due to its globality. Despite that, the aquarium attracted the passengers and created a desirable interactive experience. However, the passengers were less impacted by the more apparent and noticeable Islamic identity indicators as they were merged with modernized contemporary design features.
Identity indicators create a sensory experience in airport terminals, creating a relationship between the users/travelers and the place. Emotional attachment with identity indicators is dynamic and divergent according to different variables such as their place in the airport and the time of interaction within the traveling procedures during a trip. The presence of a dominant identity indicator that is eye-catching and interactive in the design to attract attention and affirm the identity is more impactful than having many dispersed themes of identity indicators distributed without a continuous scenario that engages passengers. On the other hand, presenting historical or traditional references as pasted elements on contemporary furniture might deprive designs of the required identity essence if not handled deeply.
Consumer spaces in airports, such as food courts and duty-free zones, could be viewed as opportunities to brand the cities in which they are located. Instead of utilizing globalized features to articulate these spaces, it is preferred to enhance identity indicators by designing them to resemble/visualize various traditional zones that are considered heritage, cultural, and touristic landmarks in the cities. This enhances the mental images the passenger conjures up in their mind, generating a narrative bond to the space, which is turned into a place and fosters a psychological and sustainable emotional connection with the city, promoting the city’s tourism and economic advancement. This could be achieved by using local materials and envisioning and depicting vernacular scenery and buildings in the interior design of the spaces.
Having interior courts in airport terminals connects passengers with the outdoor landscape and building’s façades to enhance their attachment to the exterior form of the airport, showing the concepts reflected in the façades and completing the image of the airport terminal’s mass as a landmark. At the same time, natural light has a healing and stress-relieving effect. It connects the travelers with the exterior world and might emphasize the identity indicator’s role with the shade and shadows it creates, such as its effect in KKIA and PMAIA.
Using identity indicators and mimicking heritage or touristic landmarks of the host country in the consumers’ zones in the airport terminals allows users to recognize the multi-dimensional nature of their experience in a place with its experiential, social, cultural, and aesthetic dimensions for better social encounters and interaction with the place, increasing users’ attachment to the place and likely serving as a catalyst in fostering the expected economic benefits.
It is recommended to introduce identity indicators to the entire airport design and to focus on the focal points, interior landscape, and interactive elements of artworks in non-aeronautical spaces, where the stress level decreases, and the curiosity emotions increase after finalizing the traveling procedures. This will make them more enjoyable and will allow them to have the expected impact on the passengers. All identity indicators are significant, with neither one prevailing over the other. It is the handling of the indicator and the level of its ability to be interactive that favors one over the other.
Using identity indicators in airport terminals is more of a need than a luxury, as it creates a sense of place that enhances the overall traveling experience and leaves a sustainable, memorable impression on passengers. The synergy between functionality and identity indicators in designing airport terminal spaces fosters the holistic experience that prioritizes user satisfaction and enhances the host country’s image and character.
