Abstract
N
owadays, the pace of population aging is much faster than in the past, with projections showing an increase of the world’s population over 60 years from 12% to 22% in the period 2015-2050 (WHO 2015). While this demographic shift poses challenges, longevity also provides potential opportunities with their extent heavily depending on one factor: health (WHO 2015). The objective of this project is to propose a design solution that incorporates health promoting qualities using the Evidence-Based Design (EBD) process. The site regards the outdoor environment of a Copenhagen’s neighborhood, where care centers for elderly and people with dementias are accommodated.

Gardens in healthcare facilities are landscapes designed for a specific population; in this case seniors and people with dementia, and therefore should establish an age-friendly environment. Moreover, they often have a specific purpose, for example encouraging seniors to get outside for exercise, sunlight and fresh air. These environments in order to be effective in their aim and avoid adverse effects, should be designed using evidence-based health design (EBHD). The health promoting qualities are related to physical, mental and social health of the residents, also known as the salutogenic health perspective (Antonovsky 1996, Bengtsson and Grahn 2014), in order to approach an improved holistic state of well-being. This is important because, apart from the physical health which is known to decline in a person’s later life, mental health and emotional well-being are as important in older age as at any other time of life (WHO 2015). Additionally, psychological health is associated with promoting social interaction skills (Marcus & Sachs 2014). While the design concerns an institutional setting, the outdoor environment must be accessible both to the residents and the public. However, it is important to mention that strong focus has been given on the benefits of the care centers residents and less on benefits for staff and visitors. 2.

Evaluation
The Evidence-Based Health Design process. In this case, the evaluation process is not applicable.
Nowadays, awareness about how good or bad design may influence people’s well-being is increasing among the architectural and decorative design disciplines of both indoor and outdoor spaces (Stigsdotter & Grahn 2002). By following the process of EBHD we can ensure that the design will conclude to a landscape where the experiences and activities in the environment are in harmony with the user’s background and health condition, and will therefore promote an overall sense of well-being. Such an instorative environment strengthens a person’s identity and self-esteem and makes him feel part of a meaningful context (Stigsdotter & Grahn 2002). Specifically, considering the most challenging section of our target group, most progressive dementias, including Alzheimer’s disease, are irreversible (Alzheimer Association), and central to the ethics of dementia care is enhancing well-being and making the most of the strengths that are still present within a person (Schwarz & Rodiek 2007). 3.
Methodology This report constitutes an in-depth investigation of an outdoor environment design case study, where extensive data collection and in-depth knowledge of the study group has to precede the design process (Quan 2009). Since the topic is of high complexity, the appropriate methods have been used to gain insight.

Theories The following theories have been selected by a literature review as a tool for assessing the value of nature to human health and well-being, and comprehend the healing influence deriving from a supportive garden.
The Biophilia hypothesis: Kellert and Wilson 1995 The biophilia hypothesis suggests the existence of an inherent human inclination to affiliate with nature. Nowadays, in the modern world, this bond continues to be critical to people’s physical, mental health and well-being. The benefits of contact with nature often depend on repeated experience, because this biological tendency needs to be nurtured and developed in order to become functional.
Aesthetic-Affective theory: Ulrich 1984 R. Ulrich in Aesthetics and Affective Response to Natural Environments (1983) suggests that the initial response to an environment is a generalised affect, a biological reaction which can be independent of and primary to cognition. When a man is in a natural or garden environment and his affections judge it as safe, his positive feelings increase.
Attention-Restoration theory: Kaplan and Kaplan 1989 Nowadays, in our world which is overflowing with information, people increasingly experience mental fatigue. ART argues that people can enhance their concentration ability after spending time in nature. This is possible through “soft fascinations”, which are plentiful in the natural environment where a person can reflect upon in “effortless attention”.

While the belief in the therapeutic benefits of nature contact may be noted in the ancient times, the first well controlled empirical test of this hypothesis was first published in 1984 by Roger Ulrich using existing data from a hospital setting. The study reported that patients recovering from surgery who had a window view of a natural environment (trees) required shorter postoperative hospital stays, gave fewer negative evaluative comments to the nurses, and consumed less potent analgesics than patients who had a view to a brick wall. Kaplan, Kaplan and Ryan in With People in Mind (1998) support these findings. They suggest that seeing through a window can help one imaging being away from the environment that is causing him to be mentally fatigued and help him relax. 6.

Copenhagen
Context De Gamles By, has traditionally been an area designated for health care; established in 1919 with the merging of the hospital and retirement housing of Copenhagen Municipality. Nowadays, the area has mixed functions, consisting of a church, health care and children institutions, residential areas, and a number of administrative and technical functions. Until recently, the area was totally enclosed, but today it is accessible through various entrances.
The neighborhood is being used both by the De Gamles By residents as well as by the surrounding residents of Norrebro district.

Target group By Henry Dreyfuss Associates. MIT Press, 1974.
The site accommodates a range of users that consist of the residents of Kastanjehusene care center for elderly and Klarahus care center for people with dementias, in addition to their family members, the staff members as well as visitors from around Copenhagen which are all are all welcome to use the space, as it is public.
Residents Age ranges from 56 to 102 Keeping in mind that the needs and abilities of people change as they age, it is also important to consider that the abilities of individuals in the same age group are substantially diverse (CEN/ CENELEC 2014). Therefore it is important to recognize the functional and cognitive limitations range from comparatively low impairment to more extreme forms (CEN/CENELEC 2014) and also consider that a person might experience multiple disabilities.
Wheelchair users. Handicapped and Elderly.
Accordingly, the design considerations about the various impairments in sensory (vision, hearing, touch, taste/smell and balance), physical (dexterity, movement, manipulation, voice, strength and endurance) and cognitive abilities (intellect, memory, and language/literacy) (CEN/CENELEC 2014) should be incorporated in the design proposal. To ensure that the space can be used by as many people as possible without the need for adaptation and is thus accessible, the whole design process incorporates the philosophy of “Universal Design” or else known “design for all” (DfA).

Defining... ...aging
A
ging is a biological process; the result from the impact of molecular and cellular damage accumulated over time, which results to a decline in physical and mental capacity, an increasing risk of disease (WHO 2015). Common health issues associated with aging include (WHO 2015): hearing loss, cataracts and refractive errors, back and neck pain and osteoarthritis, chronic obstructive pulmonary disease, diabetes, depression, and dementia. Some people even suffer from several of these issues. Moreover, there are observations of loss of muscle weight, bone density and decrease in balance abilities. Difficulty of sleeping is also a common issue that in some cases can lead to depression. Finally, older people have lower rehabilitee- and adaptation capability that makes them more susceptible.
...dementia
D
ementia: is an overall term that describes a range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person’s ability to perform everyday activities. Alzheimer’s disease is the most common type of dementia, while Vascular dementia, which occurs after a stroke, is the second most common. The formerly widespread belief that serious mental decline is a normal part of aging has been proved incorrect (Alzheimer Association). Memory loss and other symptoms of dementia (Alzheimer Association): Impairments in memory (short-term), communication and language, ability to focus and pay attention, reasoning and judgment, and visual perception are core mental functions that are associated with dementia. While symptoms of dementia may vary greatly, in order to consider a person suffering from dementia at least two of the aforementioned mental functions must be significantly impaired. Moreover, many dementias are progressive, meaning symptoms start out slowly and gradually get worse. 12.

Design
Diagrammatic site programming The following concepts, which are based on the requirements of our target group, have been applied in the design process.
Public / Private
The Alley forms an important axis with historical significance, that visually and physically connects the main entrance to the area with the church that acts as a landmark. Therefore a change in use from vehicular to pedestrian circulation is suggested. Moreover, the six Alle buildings are situated north and south of this axis, forming a tight cluster. The recommended levels of privacy conditions are determined by the gradient, ranging from light red for public to dark red for more private context.
15.
Triangle Of supportive environments The triangle of supporting environments is a model used as a tool for determining the areas of active and passive engagement with the social and physical environment, based on the individual’s subjective experience of well-being (Bengtsson & Grahn 2014). Considering our target group, an individual experiencing low wellbeing and excessive sensibility to the environment will prefer to use areas adjusted to his residence. As the experienced state of well-being augments, he becomes capable of more outwards directed engagement and is capable of using more remote areas than the ones adjusted to his residence.
Perceived Sensory Dimensions
The perceived sensory dimensions (PSD) (Grahn & Stigsdotter 2010) have been used in a medium scale, both for means of analysis as well as a design tool. In order to proceed to decisions about the most suitable PSD’s with respect to the target group, the identified existing PSD’s are compared with the conclusions from the interview with the staff member of the care centers and the appropriate literature review. The proposed most dominant PSD’s of the each room are illustrated here.

Reflections & Conclusions This project is the result of the ‘Health Design’ course, held in the second block of 2015-2016 at the University of Copenhagen. An aspect of major importance for this course is the comprehension and proper use of the Evidence Based Health Design that combines (in balance) the best research/practice evidence, the target group’s attributes and characteristics with the landscape architect’s skills in the design process in order to provide a program that will achieve the best possible outcomes. Following the presentation of the site and project’s aim, the project argues for the importance of natural environments and nature experiences regarding the experienced state of a person’s well-being. Specifically, the project presented the redesign process of an outdoor environment primary destined for use by a very sensitive target group; the neighborhood’s residents that consist of frail elderly and people with dementias. The benefits this group gains from a supportive outdoor environment were analyzed, followed by the generation of guidelines that purpose. Finally, an outdoor design solution which considers the previous research has been proposed. The Alley that has been decongested by the vehicular circulation and transformed to a pedestrian friendly area, and the five gardens situated by it bring together design considerations for a user supportive environment with various activities that promote the enhancement of perceived well-being, strengthen the individual’s identity and self-esteem and make them feel part of a meaningful setting. Moreover, the design ensures a pleasant view from the residents windows towards the gardens so they can enjoy them throughout the year . For everyone seeking a place for quiet contemplation and contact with nature, the gardens of De Gumles By have the potential to become restorative spaces of the public realm, and provide a setting that can have significant health benefits. Taken possible limitations aside, the proposal has qualities that are beneficial for the target group as well as the other potential site users; the family members, staff and in general the residents of Copenhagen.

It was very interesting to learn about the target group’s needs, and what actions could be taken in order to make a supportive environment with restorative features. Especially considering that the target group is not other than our future selves and beloved ones.
