Historical built environment deserves particular attention in this regard. Urban regeneration projects are particularly complex here because of the dense urban fabric and the risk of damage to the heritage values. In order to understand how to overcome these challenges, we explore the concept of urban acupuncture in this research. The urban acupuncture focuses on small, precisely targeted, rapid and usually low- cost changes that positively affect social, ecological, and even economical and physical dimensions of the surrounding environment. The aim of this research was to identify the recent interventions in historic urban environment of Kaunas city (Lithuania) that can be seen as the analogues of urban acupuncture and to evaluate them using the designed set of criteria integrating the characteristics of urban acupuncture, the patterns of socially and ecologically responsible biophilic design and the requirements for preservation and development of historic built environment. Keywords: urban acupuncture, urban intervention, historic urban environment, Kaunas. This article deals with the concept of urban acupuncture that has emerged as a part of knowledge transfer trend in urban studies. It involves applying holistic Eastern medicine concepts in urban design and management (Marciano, 2016) and is based on the precisely localized interventions in the urban fabric in order to regulate so-called “energy flows” (ecological, sociocultural, socio- economic, and information flows) in the city, so that it can function successfully. The movement and activities of people, the ecological flows, the information flows and exchange can be consid- ered as “energy” in urban acupuncture; meanwhile elements of urban structure, including streets, squares, green areas, buildings etc. can be metaphorically considered as the “organs” of the city (Casagrande, 2010; Khaerani, 2014; Lerner, 2014). As the experience demonstrates, urban acu- puncture can be applied locally and systematically (Tortosa et al., 2010). The “needles” of urban acupuncture can be various types of interventions and events ranging from the building or park to street festival or any other positive happening in public spaces (Lerner, 2014). Urban intervention in this this research is considered as the art objects or design solutions in the urban environment, creating a public space or integrated in the existing space and giving it a new expression. Most often, the urban interventions are aimed at addressing social, ecological, local identity and similar problems and creating the new quality in the environment. Urban acupuncture intervention here is considered as the intervention or the system of interventions in the selected points of urban fabric with social, economic, ecological or other potential in order to activate their “energy” and affect the surrounding territories. Journal of Sustainable Architecture and Civil Engineering 2018/2/23 6 Framework and methods of research Urban acupuncture is more efficient in densely built and densely populated urban fabric (Walker, 2015), usually characteristic to historic urban environment. This research is concentrated on the interventions having the character of urban acupuncture in historic urban environment; historic urban environment, according to Vienna Memorandum (2005), here „refers to ensembles of any group of buildings, structures and open spaces, in their natural and ecological context, including archaeological and palaeontological sites, constituting human settlements in an urban environ- ment over a relevant period of time, the cohesion and value of which are recognized from the archaeological, architectural, prehistoric, historic, scientific, aesthetic, socio-cultural or ecological point of view.“ Based on the potential benefits of urban acupuncture in historic urban environment, seven hypothetical statements of the research were formulated: 1. Urban acupuncture interventions in historic urban environment can be beneficial for the ac- tualization of heritage, for highlighting of its’ valuable features, and attracting attention of the society. 2. Applying the principles of urban acupuncture allows developing, improving or adding new fea- tures to the system of public spaces of a historical part of the city. 3. Successful urban interventions correspond to the basic principles of biophilic design (Browning et al., 2014) and urban acupuncture (Lerner, 2014). 4. The architectural-urban context determines the type of urban acupuncture interventions. 5. Interventions of urban acupuncture can influence the ecological system, can restore or create biodiversity, ecological balance and the links between humans and nature. 6. Urban acupuncture interventions in the historic environment can create or re-create social vi- ability. 7. Urban acupuncture interventions can positively affect the urban landscape. The aim of the research is to identify the recent interventions (in a timeframe of 5 years) in the his- toric urban fabric of the second largest Lithuanian city Kaunas that can be seen as the analogues of urban acupuncture and to evaluate them using the designed set of criteria in order to test the above-presented hypothetical statements. The methods of research include the analysis of liter- ature, the classification of urban acupuncture interventions and the design of the set of criteria for their evaluation, the identification of interventions, that can be seen as the analogues of urban acupuncture in Kaunas historic urban fabric and their evaluation using the designed set of criteria, generalization and formulation of conclusions. The research was aimed at finding and evaluating the analogues of urban acupuncture in the his- toric environment of Kaunas; thus the classification of urban acupuncture interventions and a set of criteria for their evaluation were necessary. After the analysis of examples and literature (Le- rner, 2014; Network…, 2018), it was noticed that some interventions have a temporal impact and the impact in a very limited space, some interventions have a wider (for example, district level) impact, there can be individual and systematic interventions (Tortosa et al., 2010). Consequently, four types of possible urban acupuncture interventions were distinguished in this research: _ non-physical intervention (does not have a permanent physical form, but has a significant im- pact on the viability of the site, for example, the iconic music piece, tradition, street artists); _ intervention of local impact (affecting only the surrounding environment, for example, the square, where it is located); _ intervention of wide impact (localized in one place, although affecting the viability of a wider area, for example, the district); _ systemic intervention (forms a certain network of spaces in order to influence the whole city). The urban acupuncture concept integrates social, ecological and spatial aspects, thus the system of criteria for evaluation of urban acupuncture interventions should encompass these dimensions as 7 Journal of Sustainable Architecture and Civil Engineering 2018/2/23 well. The previous experience of assessment of public spaces was applied; the set of criteria for the assessment of urban acupuncture interventions was created integrating the public space assessment questionnaires from the Project for Public Spaces (Project..., 2018), characteristics of urban acupunc- ture (Casagrande, 2010; Khaerani, 2014; Lerner, 2014), the 14 the patterns of socially and ecologically responsible biophilic design formulated by Terrapin Bright Green (Browning et al., 2014), the principles of sustainability and the requirements for preservation of historic built environment. The possibility to give scores to some of the indicators and to calculate an overall assessment in order to compare the interventions was envisioned as well. The set of criteria was structured into five sections: 1. General data. General data includes the description of the intervention: its’ location, the date of implementation, the area in sq. m, the period of implementation, envisioned time of existence, functions, the cost in Euros, financing source, author(s) and the client (initiator(s)) of the project. 2. Assessment of social and psychological aspects. This section integrates the characteristics and the questions for their evaluation targeted at sociability, activities, and functions with reference to the Project for Public Spaces. The Project for Public Spaces is a non-profit organization that anal- yses more and less socially successful public spaces and had distinguished a system of criteria for their assessment. The system includes such sets of characteristics as access and linkages, comfort and image, uses and activities, and sociability and presents the array of observation and public space assessment questions, part of which is integrated in this research (Table 1).

The promise of more information, achieved through partially obstructed long-distance views, design revelations, surprising installations or unexpected architec- tural features drawing in and engaging with the environment. Risk / peril The thrill of danger from an identifiable risk, coupled with the sense of a reliable safeguard. Journal of Sustainable Architecture and Civil Engineering 2018/2/23 10 4. Assessment of ecological aspects. The assessment of ecological aspects of the interventions is based on the 14 patterns of biophilic design. The 14 patterns were developed by environmental consulting and strategic planning company Terrapin Bright Green, which is committed to im- proving the human environment through high-performance development, policy, and related re- search. These patterns are grouped into three categories: Nature in the Space Patterns (visual connection with nature, non-visual connection with nature, non-rhythmic sensory stimuli, ther- mal and airflow variability, presence of water, dynamic and diffuse light, connection with natural systems), Natural Analogues Patterns (biomorphic forms and patterns, material connection with nature, complexity and order), Nature of the Space Patterns (prospect, refuge, mystery, risk/ peril) (Browning et al., 2014; Biophilic, 2017) Three categories of patterns and additional features related with the ratio of greenery in the area, pollution, ant the use of sustainable materials in the implementation of the project are included into the assessment of ecological aspects (Table 3). 5. Assessment according to the principles of urban acupuncture. The assessment of the interven- tion according to the principles of urban acupuncture includes such criteria as bringing new life and people to the urban area, highlighting the potential of the place, being stimulus to commu- nity life, identity re-creation or development, development of missing features of the urban fab- ric, stimulation of diversity of activities (Casagrande, 2010; Khaerani, 2014; Lerner, 2014). Each of these criteria can be evaluated in scores: 1 – positive assessment; 2 – partial correspondence to the criterion; 0 – the intervention does not correspond to the criterion.

Results and discussion 11 Journal of Sustainable Architecture and Civil Engineering 2018/2/23 Three interventions (Cabbage Field area in a historic district Šančiai and Street Art Zone and Court- yard Gallery initiative in Kaunas New Town) were selected for further detailed analysis and evalu- ation. The criteria for selection of these interventions were the following: the intervention must be implemented in the historic urban fabric, the intervention must provide the space accessible for pedestrians, the intervention should generate public space and gather community, and this must be still existing intervention. Each of three interventions was evaluated according to the prepared set of criteria in an expert evaluation by the authors of the research. The interventions received score for each point, which had the possibility of evaluation in scores, after that these were calculated into total score. After this the total score was multiplied by 5 and divided by the maximum possible evaluation in scores for each section. The multiplying by 5 was necessary to receive the final evaluation score in the five scores scale. Table 5 and table 6 demonstrates the evaluation in scores of social and psycho- logical aspects and the correspondence to urban acupuncture features of selected interventions. In the table 7 the summary of evaluation is presented.

This place acts as attraction point during events only, however it is the place where strong bonds of the community can be perceived. It plays a role of the meeting place of the community and has a wide variety of functions and attracts the diversity of people during events, however at other times it is totally abandoned. This place supplements the system of public spaces of the area and is probably the largest and the only one space for public events in Šančiai historic district. However, sense of safety, comfort and the image of the place are very poor. Even if the Cabbage Field is characterised by the largest ratio of green space, its quality as a green public space is low. However, it was the place, which satisfied the principles of urban acupuncture the best – it has brought new energy to the liveliness of the area, strengthened bonds of the community and encouraged the development of local identity.

Fig. 1. Cabbage Field in Šančiai (authors’ pictures) Courtyard Gallery took the second place of evaluation according to the criteria. This place has formed a very strong and active attraction point, having visual connections with other spaces. Strong relations between community members are apparent here. The residents seem to be connected to the place as well. As a Cabbage Field, it also enriched Kaunas as one more public space. The space is felt as safe and visually appealing. People here are taking a lot of photographs. Even though it has very few natural features (which is quite complicated in such urbanised area), it gained quite good score in ecological evaluation because it had a lot of biophilic features, such as spatial hierarchy, prospect, refuge, mystery, peril, etc. According to urban acupuncture features, the place received good evaluation because it matched most of the principles.

The place did not form active attraction point. It functions more as a passageway rather than a public space. It is not lively at all, which might be influenced by its remote location, lack of visual connections. Developing the site, the opportunity was not taken to make use of the river nearby – the site has no other connections with it except that it runs nearby. The sense of safety is poor and the image is more like abandoned space (even if it is clean) rather than space for creativity. According to urban acupuncture principles, it supposed to act as acupunctural point, however bonds of the community did not emerge in this place and the place might be too much remote to be lively; however, as unexpected feature of environment it is very welcomed.

It is not lively at all, which might be influenced by its remote location, lack of visual connections. Developing the site, the oppor- tunity was not taken to make use of the river nearby – the site has no other connections with it except that it runs nearby. The sense of safety is poor and the image is more like abandoned space (even if it is clean) rather than space for creativity. According to urban acupuncture principles, it supposed to act as acupunctural point, however bonds of the community did not emerge in this place and the place might be too much remote to be lively; however, as unexpected feature of environment it is very welcomed.

The research showed that urban acupuncture interventions were beneficial for historic environment because they supplemented its value by new features: new public spaces emerged, attention of the society was attracted to neglected spaces, liveliness was brought to some heritage sites. 2.

The research showed that urban acupuncture interventions were beneficial for historic environment because they supplemented its value by new features: new public spaces emerged, attention of the society was attracted to neglected spaces, liveliness was brought to some heritage sites. 2. Urban acupuncture interventions added a lot of new features and improved the system of public spaces in Kaunas historical part. 3. The analysed interventions corresponded to the most of biophilic design and urban acupuncture features. 4. The research did not show that architectural-urban context would determine the type of urban acupuncture intervention – it was very diverse. 5. It was not possible to evaluate in this research if urban acupuncture interventions can influence the ecological system, restore or create biodiversity, ecological balance or the links between humans and nature because there was no such ecology-based intervention in Kaunas. 6. It was found that urban acupuncture interventions can definitely create or re-create social via- bility in the urban space. 7. Urban acupuncture interventions definitely positively affect urban landscape and bring new values to it. 1 The concept of urban acupuncture is based on the precisely localized interventions in the ur-ban fabric in order to regulate the ecological, sociocultural, socioeconomic, and information flows in the city, so that it can function successfully. The research had identified numerous recent interventions in the urban fabric of Kaunas, that can be seen as the analogues of urban acupunc- ture. Three interventions - Cabbage Field area in a historic district Šančiai and Street Art Zone and Courtyard Gallery initiative in Kaunas New Town – were selected for further evaluation. 2 The system of criteria designed for the assessment of urban acupuncture analogues in-cludes sections: general description, assessment of social and psychological aspects, as- sessment of urban-architectural aspects, assessment of ecological aspects, assessment ac- cording to the principles of urban acupuncture. 3 The assessment has demonstrated that the majority of recently implemented interven-tions are of artistic or street art character and usually do not create a usable public space. 4 The selected space-creating interventions had successfully enlivened and added some values to the system of public spaces in Kaunas, and helped to direct the attention to abandoned and derelict urban areas. The wide impact intervention Courtyard Gallery attracted visitors from different parts of the city. The analysed cases had revealed the mutual links between communities and interventions: the Cabbage Field was initiated by the community; meanwhile the initiator of the Courtyard Galley has realized his ideas first and then the neighborhood community has emerged. 5 However, it can be concluded that analysed interventions lack components that create so-cial and ecological processes. Even if these spaces are viewed positively by the society, their potential is not fully employed. 6 No systemic urban acupuncture interventions and interventions making significant impact on city-scape were found in Kaunas currently. The ecologically influential interventions were lacking as well. Conclusions References Browning W., Ryan C., Clancy J. 2014. 14 patterns of biophilic design.
