Acknowledgement In these few lines I would like to thank a couple of people who have made this Thesis possible. First and foremost I offer my sincerest gratitude to my supervisor, Joris Fach, for his patient guidance, encouragement and advice he has provided throughout my time as his student. I have been extremely lucky to have a supervisor who cared so much about my work. I would also like to thank all the members of staff at Hochschule Anhalt who helped me in my supervisor’s absence. I am also very grateful to Andrea, my partner, for her constant motivation, encouragement and for her love during these years. Many thanks go to my parents, my sister and the rest of the family, for their wise counsel and sympathetic ear when I needed it and for feeling so close despite being so far away. Last but not least I would like to send out a special thanks to Hugo and Angi Scheepers for all their emotional support as well as the financial aid. The opportunity to study abroad would not have been possible if it wasn’t for you. I truly appreciate what you have done for me and I will be forever grateful.

RECOVERY
7
In a health obsessed society, in which fitness clubs and organic food stores spring up at every street corner, the loss of agility and productivity is not an option. Hence, whenever bad luck does strike, it causes daily routines to collapse. Recovery always takes too long and lasting dysfunctions are ruinous. As such, our health has become part of a social equation, differentiating often underfunded public care from exclusive private rehabilitation centers. Additionally, the ownership of health-related data has become highly sensitive, as it is utterly valuable to both pharmaceutical companies, as well as future employers. Overall, however, the health care industry is one of the most reliably growing ones of recent years. Hospitals have expanded into imposing conglomerates of impenetrable bigness that often fail to connect to their context on almost every level. Pharmaceutical enterprises treat themselves to lush campuses, marking their newly acquired power and influence. Keeping all of the above in mind, we will commence the semester by looking at the human body itself, understanding its organic functions and amazing resilience, but also study sports injuries, chronic diseases, psychological instabilities, drug addictions and their respective treatments. As the radius of mobility become restrained, the design of immediate surroundings becomes crucial. We will thus speculate on productive environments for recovery, imagining paradisiacal states of urban arcadia in which physical rehabilitation overlaps with exciting cultural programs, making every step of a recovery an exciting one for both body and mind.

HIV, the virus that causes AIDS, is one of the world’s most serious health and developmental challenges. Since the onset of the epidemic in the 1980s, more than 70 million people have been infected with the virus and about 35 million people have died. Currently about 36.7 million people are living with HIV. The burden of this epidemic continues to vary considerably between countries and regions. Sub-Saharan Africa remains most severely affected, with nearly 1 in every 25 adults (4.4%) infected, accounting for nearly 70% of the people living with HIV worldwide (World Health Organization, 2016). Namibia, my birthplace and home, is one of those Sub-Saharan countries highly affected by the virus. It currently has the 5th highest HIV prevalence rate in the world, with a total of 13,3% of the population infected. This has drastically impacted on the countries health indicators, posing serious developmental challenges. Providing universal access to HIV services and infrastructure, has been a priority for the Namibian government for the last ten years and the country has shown that achieving a massive scale-up of HIV services in a short period of time is feasible, given sufficient political commitment, social mobilisation and financial investment (World Health Organization, 2014). The proposal for this research study will be an introduction of new architectural interventions, that will seek to provide comprehensive and quality treatment, counselling, prevention campaigns, testing as well as care and support for those already infected by HIV/AIDS and the ones that are at risk. Due to the fact that Namibia is so sparsely populated, I want to focus on the rural communities, as most of them have little access to health services. Since this adresses the whole country, the proposal will consist of a masterplan, introducing several interventions, spread throughout Namibia´s 13 regions. In total there will be 11 new facilities, composed of a central hub and 10 smaller modules. The central hub will be located in the capital city of Windhoek and will serve as a supplier to all the smaller modules, providing them with health staff, medication and support. In return these modules will reach out to all the remote areas by means of mobile clinics, covering identified areas within the country. Apart from the necessacity and function of these facilities, the architecture will envision a sustainable and feasible approach, making use of affordable local materials and building techniques.

“ Abantu Abaafa! – People are dying! An elderly woman calls to us from a village in Uganda. She says what everybody knows. People are dying from AIDS. Her thin arms are held out imploringly. She is distraught. The skin hangs in folds where once there was flesh. She is in her eighties and cares for her many orphaned grandchildren. People are dying – they are and were and will be her children and grandchildren. She cares for them, but when she dies they are orphaned once again. They grow up. They too may become infected and die of AIDS. No one listens.“ (Barnett & Whiteside 2002, 3)

What is HIV / AIDS? HIV stands for human immunodeficiency virus. If it is left untreated, it can lead to the disease called AIDS (acquired immunodeficiency syndrome). Unlike other viruses, the human body can’t get rid of HIV completely. So once you have picked up the virus, you have it for life. HIV attacks the white blood cells in the body, which help the immune system fight off any infections. If however the virus is not treated, it can greatly reduce the number of these cells, making the person more vulnerable to pick up a disease. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and diseases anymore. These opportunistic infections take advantage of a very weak immune system and signal that the person has AIDS, the last state of HIV infection. (U.S. Department of Health & Human Services, 2016) 1. Infected with virus 2. Virus attacks the T-cells 3. HIV copies itself and starts attacking other uninfected T-cells

Where does HIV come from? Research shows that HIV first infected humans in sub-Saharan Africa. Scientists believe that a chimpanzee in Central Africa was the source of HIV infection in humans. They are convinced that the chimpanzee version of the immunodeficiency virus (called simian immunodeficiency virus, or SIV) was most likely transmitted to humans and mutated into HIV when humans hunted these chimpanzees for meat and came into contact with their infected blood (Gallant 2016, 14). Studies show that HIV may have jumped from apes to humans as far back as the late 1800s. Over decades, the virus slowly spread across Africa and later into other parts of the world (AVERT,2016).

How is HIV spread? The HIV virus can only be transmitted through specific activities. The most common actions are: 1. Sexual intercourse 2. Mother to child transmission 3. Needle or syringe use 4. Blood transfusion There are only certain body fluids from a HIV infected person that can transmit the virus such as: Blood, semen (cum), pre-seminal fluid (precum), rectal fluids, vaginal fluids and breast milk (U.S. Department of Health & Human Services, 2016). These body fluids must come into contact with a mucous membrane or damaged tissue or be directly injected into your bloodstream (by a needle or syringe) for transmission to occur.

Not spread by? HIV cannot survive long outside the human body (such as on surfaces) and it does not reproduce outside a human host. It is not spread by: 1. Mosquitoes, ticks or other insects 2. Closed-mouth or “social” kissing with someone who is HIV-positive 3. Sharing toilets 4. Other sexual activities that don’t involve the exchange of body fluids such as shaking hands, hugging, sharing dishes/drinking glasses Thus, compared to many other viruses, HIV is not easily passed on but great care and responsibility still has to be taken.

Stages of infection 1. Early stage of HIV Some people may experience a flu-like illness within 2-4 weeks after HIV infection, but others may not feel sick during this stage at all. During this time, HIV infection may not show up on an HIV test, but people who have it are highly infectious and can spread the infection to others. 2. Chronic HIV infection After the early stage of HIV infection, the disease moves into a stage called “chronic HIV infection”. During this stage, HIV is still active but reproduces at very low levels. People with chronic HIV infection may not have any HIV-related symptoms, or only mild ones. For someone who is not taking medicine to treat the virus, this period can last a decade or longer, but some may progress through this phase faster. 3. AIDS AIDS is the final stage of HIV infection. At this point the virus has damaged the immune system so much, that the body can´t fight off opportunistic infections any longer. Without treatment, people with AIDS typically survive about 1-3 years (AIDSinfo, 2016). Years

Other infections related to HIV / AIDS People that have strong immune systems can be exposed to certain viruses or bacteria without having any reaction to them. However, people that live with HIV/AIDS can face serious health threats from what are known as “opportunistic” infections (OIs). These infections are called “opportunistic” because they take advantage of your weakened immune system, and they can cause devastating illnesses. They are the most common cause of death for people with HIV/AIDS. (U.S. Department of Health & Human Services, 2010) This list shows some of the most common Opportunistic infections that are considered AIDS-defining conditions: 1.Tuberculosis 2.Pneumonia 3.Invasive cervical cancer 4.Toxoplasmosis 5.Cryptococcal meningitis 6.Herpes simplex: chronic ulcer(s) or bronchitis 7.Histoplasmosis Worldwide, tuberculosis is the most common infection among people living with HIV. It can be very serious and if it is not treated, it can kill.

How do you know if you are infected? Despite the flu like symptoms at the beginning of the infection a person cannot and should not rely on them to tell whether he/she has HIV. The only way to know for sure if you have HIV is to get tested. Knowing your status is important because it helps a person make healthy decisions to prevent getting or transmitting HIV and to immediately take medication. Flu-like symptoms for ca. 4 weeks
No symptoms for ca. 10 years
Weight-loss dying 1-3 years
Due to the lack of symptoms a lot of people dont know that they have picked up the virus and therefore don´t bother to get tested. These people are at risk of developing AIDS or of passing the virus on to others at a huge cost to themselves and to society. Its thus so vital to get the word out and to give everyone access to proper counselling and education. 36,7 million people are living with HIV globally

What the world says about HIV History will judge us on how we respond to the AIDS emergency in Africa....whether we stood around with watering cans and watched while a whole continent burst into flames....or not. Bono
Stigma hurts. Because of AIDS, children are bullied, isolated and shut out of school. They are missing out on education. They are missing out on medicines. Children are missing your love, care and protection. Join me. And become a stigma buster. Jackie Chan
It‘s not fair that people ignore AIDS in Africa because it‘s Africa. It‘s not fair. India Arie
The heart of the security agenda is protecting lives - and we now know that the number of people who will die of AIDS in the first decade of the 21st Century will rival the number that died in all the wars in all the decades of the 20th century. Al Gore

I have friends of mine who have died of AIDS and many of those friends…did not tell me until the very end...because they felt that there was a stigma, a taboo, attached to it…now we have more women infected with HIV/AIDS, many of those women were infected by their husbands who did not tell them. Bianca Jagger
We want the world to focus on children whose lives have been devastated by AIDS. The millions of children who are missing their parents; their childhood, their future but most importantly, they are missing YOU. Everyone can make a real difference. Your voice is needed in a global movement that can change their world. Pierce Brosnan Let us give publicity to HIV/AIDS and not hide it, because [that is] the only way to make it appear like a normal illness. Nelson Mandela
AIDS is no longer a death sentence for those who can get the medicines. Now it‘s up to the politicians to create the „comprehensive strategies“ to better treat the disease. Bill Clinton

Exploring HIV in Namibia I chose to investigate the HIV epidemic, focusing on Namibia, which is is a country in southern Africa (marked in red) whose western border is the Atlantic Ocean. It shares land borders with: 1 Zambia 2 Angola 3 Botswana 4 South Africa I am particularly interested in Namibia because I was born there. I have lived in the country for most of my life and have witnessed the vast effects that HIV is having on its economic development. Namibia currently has the 5th highest HIV prevalence rate in the world. With the disease being recorded the leading cause of death since 1996, it has become much more than a health problem for the country. AIDS is a threat to the very fabric of Namibian society, affecting mostly adults in their prime.

Population and regions of Namibia Namibia is the second least populated country in the world, with only 2.56 people per square kilometer. The current population is estimated at 2,51 million with a rate of about 1,9% annual increase (Countrymeter, 2016). Namibia is divided into 13 regions and subdivided into 121 constituencies. The largest city and capital is Windhoek, with a population of about 325,800. This is the only city with a population exceeding 100,000. The next-largest city is Walvis Bay, with about 95,000 people.

Currently there is no effective cure for HIV, but with proper treatment and medical care, HIV can be controlled. The medicine used to treat HIV is called anti-retro-viral therapy or ART. Presuming that the ART is taken on time, every day, this medicine can dramatically prolong the lives of many people with HIV, keep them healthy, and greatly lower their chance of transmitting the virus to others. Â A HIV infected person who is treated before the disease is far advanced, and stays on treatment can live nearly as long as someone who does not have HIV (U.S. Department of Health & Human Services, 2016).

Antiretroviral therapy HIV is treated using a combination of medicines to fight HIV infections. This is called antiretroviral therapy (ART). ART isnâ&#x20AC;&#x2122;t a cure, but it can control the virus so that you can live a longer and healthier life. It is important for a patient to adhere strictly to an ART regimen to ensure a successful response to treatment and to avoid viral rebound or drug resistance. Research has shown that adherence levels of 95% or higher are required to ensure such success (Paterson et al., 2000). These medicines prevent the virus from multiplying, reducing the amount of HIV in your body. This gives your immune system a chance to recover and fight off infections and cancers. Even though there is still some HIV in the body, the immune system is strong enough to fight off infections and cancers. ART not only helps the body to recover from the virus but also reduces the chances of transmission. If an HIV-positive person adheres to an effective antiretroviral therapy regimen, the risk of transmitting the virus to an uninfected sexual partner can be reduced by 96%. This makes HIV treatment a new priority prevention option. ART is recommended for all people with HIV, regardless of how long theyâ&#x20AC;&#x2122;ve had the virus or how healthy they are. If left untreated, HIV will attack the immune system and eventually progress to AIDS. (AIDS info, 2016)
52
TREATMENT
Without treatment:
HIV virus enters the body as soon as the person gets infected
HIV virus attacks the white blood cells (T-cells)
HIV virus multiplies and starts attacking uninfected T-cells
With Antiretroviral therapy:
HIV virus enters the body as soon as the person gets infected
ART drug ataches itself to T-cells and repells the HIV virus
TREATMENT
T-cell remains uninfected maintaining a strong immune system
53
Life expectancy The World Bank projects that by 2020, the life expectancy in SubSaharan Africa will be 43 due to AIDS, rather than 62 without AIDS (Whiteside 1998, 22). However, Antiretroviral therapy can help HIV patients live longer. In Namibia, people with HIV who start treatment with antiretroviral therapy, have life expectancies of around 80% of that of the general population (67) provided that they start treatment before their CD4 count drops below 200 (cells per microliter). These findings are encouraging and show that with long-term treatment, HIV can be managed as a chronic illness in middle- and low-income settings (ScienceDaily, 2013).

The effects of Antiretroviral therapy Since the introduction of Antiretroviral therapy many HIV life´s were saved. A 2010 documentary film, called ``The Lazarus effect`` illustrates the transformation effect of life-saving antiretroviral medicine through the stories of HIV+ people in Zambia (The Lazarus Effect, 2010). By taking the medication in as few as 40 days, the medicine can help bring people back to life. Here is a short story of Concilia Muhau, one of the patients starring in the documentary:
Concillia Muhau is 26 years old. She started ARV therapy in 2004, but when she began to feel better, she stopped taking the drugs. In early 2009, she became very ill. At her worst, she weighed just 29 kg. “The way I was feeling” she submits mere months later, “It was like I was already dead. ” (Concilia Muhau) In March 2009, Concillia started ARV treatment for a second time (Oprah, 2010). Now healthy, Concillia recently completed a HIV peer education course at the Kanyama Clinic in Zambia and is a volunteer, educating people about the importance of the adherence to the medication. “Now, I feel like I‘ve been given another chance to be able to take care of my beautiful daughter.“ (Concilia Muhau)

55
The history of the Antiretroviral therapy In 1995 clinical trials for ARVs were initiated & approved as a standard treatment in the US which saw an immediate decline in deaths. In Africa however, deaths only declined in 2007 Why the gap? Drugs were too expensive - $10,000 USD per person per year Why were the drugs so expensive? The pharmaceutical companies put a patent on the drugs setting prices as high as they wanted because they had exclusive rights. Thus Africas market for ARVs consisted of just 1% of total revenues. Meanwhile in Thailand and India, generic companies produced drugs at a reduced price from $10,000 per patient annually, to $365 per patient Because of the rights to exclusivity on ARVs, African countries were not allowed to import cheaper generic drugs from India or Thailand Why not allow countries in Africa to import generic drugs? Pharmaceutical companies were worried that allowing certain countries to import generic drugs would set a precedent, encouraging other countries, including the United States, to try to do the same. African countries actively protested against those patents, to allow the importation of generics In 2001, after a long fight, the South African government began importing generic drugs into Africa without protest from Western countries, which saw a great decline in deaths Although African countries are now able to import generic ARVs, the problems of affordability and accessibility are far from over. Many other patented drugs remain out of reach for people in developing countries.

People receiving Antiretroviral therapy globally Regardless of all the challenges, new global efforts have resulted in an increase of people receiving HIV treatment in recent years, particularly in resource-poor countries. Since December 2015, 17 million people living with HIV were receiving antiretroviral treatment (ART). This means that 46% of all adults and 49% of all children living with HIV are now accessing ART (Global HIV and AIDS Statistics, 2016).

Cost of Antiretroviral therapy The estimated cost per patient - year of treatment varies widely across individual patients and country settings. In low-income and lower middle-income countries such as Namibia, the mean cost per patientyear of treatment is $642 (PEPFAR, 2013). This estimated total represents the full cost of providing ART and supportive services and includes all resources required to provide comprehensive treatment at and above the site level. These include: - Antiretroviral drugs (ARVs) for patient treatment - Non-ARV recurrent costs such as: - Clinical staff salaries and benefits - Laboratory and clinical supplies - Non-ARV drugs for opportunistic infections - Building utilities - Travel - Contracted services - Investment costs such as: - ARV buffer stock (inventory) to support a reliable supply chain - Building renovation & construction - Laboratory and clinical equipment - In-service training of ART providers - Program management and central support costs

Supply of Antiretroviral therapy Since the manufacture of generic antiretroviral drugs, Namibia has mainly received their medical supply from Asian pharmaceutical companies such as India and Thailand. However, since the beginning of 2016, Minister of Health and Social Services, Dr Bernard Haufiku said that “the government would be purchasing ARVs from Uganda from now on, as they are cheaper compared to Asian countries.“ (New Era, 2016). In April 2016, Namibia received the shipping of 70 tonnes of anti-retroviral medicines worth $4 million by Uganda’s Cipla Quality Chemicals Ltd, which accounts for the single largest export order for an East African pharmaceutical company.

Funding organisations Namibia receives funding from various countries but the bulk of the donor funds comes from the United States government. The two main sources of international funds for ART in Namibia are the United States President’s Emergency Fund for AIDS Relief (PEPFAR) and the international Global Fund to Fight AIDS, Tuberculosis and Malaria (the Global Fund).
U.S. President´s Emergency Plan for AIDS Relief
The President‘s Emergency Plan For AIDS Relief is a United States governmental initiative to address the global HIV/AIDS epidemic and help save the lives of those suffering from the disease, primarily in Africa. PEPFAR works to jointly plan, implement and monitor US - Namibia co-investments to achieve epidemic control and foster a sustainable response.
To Fight AIDS, Tuberculosis and Malaria Founded in 2002, the Global Fund (GF) is a partnership between governments, civil society, the private sector and people affected by the diseases. The Global Fund raises and invests nearly US$4 billion a year to support programs run by local experts in countries and communities most in need and has contributed significantly to the costs of antiretroviral medication and laboratory costs,

Namibian HIV / AIDS expenditures In comparison to other countries in Sub-Saharan Africa, Namibia´s health budget is the second highest after South Africa (Ministry of Health and Social Services 2010, 11). Taking reference from Namibias budget statement, over 27% of the countries national budget is granted for the health sector. Of that amount the government contributes 64% to the HIV budget (Ministry of Health and Social Services 2015, 29). The list below shows the latest expenditures by all the funding sources: Sources:

Barriers keeping patients away from medication Eventhough Antiretroviral medication is readily available in Namibia only 69% of the people, eligible for the treatment were reported to have received the medication. A recent survey identifies access barriers to ART for HIV-positive patients and their relevance in Namibia. The findings provide evidence that more tailored interventions have to be introduced to increase ART-uptake (Seeling et al. 2014, 268-275).
Fear of stigma and discrimination Staff shortage Lack of adequate counseling space High staff turnover Inadequate training for staff Lack of knowledge of patients Fear of indirect treatment costs Religious issues Inadequate communication skills Accessibility of HIV services Availability of antiretroviral drugs

Factors for low medication adherence In a similar survey, health workers were asked about what factors they thought made it difficult for their patients to attain high levels of ART adherence. These responses were categorised under the following themes: forgetfulness, difficulty accessing the hospital, poverty issues, alcohol and drug abuse, unexpected events, stigma, instructions and lack of support (Ministry of Health and Social Services 2013, 31).

Besides the effective Antiretroviral therapy, a HIV positive patient has many more needs in order to cope with the virus. HIV/AIDS is often associated with a range of psychosocial weight that must be addressed throughout all stages of the infection. Psychological support is therefore critical for helping individuals, couples, and families affected by HIV to cope with their emotions and psychosocial needs.

Psychosocial impacts of an HIV diagnosis Newly diagnosed HIV-infected patients may have little knowledge or a distorted picture about the HIV disease. A commonly held belief, especially in the pre-Antiretroviral era, is that one would have to give up any plans for the future and live in ill health for the rest of the days to come (Iris WS Chan, Rita WY Chung, 2007). As soon as patients get diagnosed HIV positive, they would show a variety of different reactions. The most common responses include:
shock
disbelief
anger
denial
fear
anxiety
depression
guilt

Steps to follow once infected with the virus People diagnosed with the virus should follow strict steps in order to live a healthy and long life:
Step 1: See a health care provider Prompt medical care and treatment with HIV drugs as soon as possible is the best way to stay healthy. People with HIV should work closely with their health care providers to decide what HIV medicines to take.
Step 2: Get a HIV baseline evaluation This evaluation includes all the information collected during a person´s initial visits with a health care provider. It includes a review of the person´s health and medical history, a physical exam, and lab tests.
Step 3: Start with a HIV regime A HIV regime is a structured treatment plan designed to improve and maintain the health, which usually consists of a combination of antiretroviral drugs.
Step 4: Find support Talk with others who have been diagnosed with HIV and AIDS and ask doctors if they know of any support groups.
72
PATIENT NEEDS
Step 5: Tell others Deciding to tell others that you are HIV positive is an important personal choice. It can make a big difference in how you cope with the disease. .
Step 6: Monitor your health Once you have been diagnosed with HIV, you need to pay closer attention to your health than you did before. Maintain a healthy lifestyle such as good nutrition, exercise, control of recreational substance
Step 7: Go for regular tests and counseling Make sure that the virus has not reactivated the blood cells, by having picked up a new infection or by having missed a few doses of the medication. .
Step 8: Move forward with your life Life does not end with a diagnosis of HIV. In fact, with proper treatment, people with HIV usually live long healthy lives. .

The story of Veronica Kalambi Written by Kaula Nhongo on 05 December 2014 FINDING out that she was HIV positive 12 years ago came as such a big blow. Thoughts of death filled her mind on a daily basis. From the death thoughts, she went through the denial phase where she managed to convince herself that the doctors had made a mistake. She shied away from people; pushing away her closest friends because of fear that they would discover the secret that she vowed would die with her. For years, Veronica Kalambi struggled with accepting her HIV status and making the move towards living positively. “How could I learn how to live with it when I was not even prepared to accept it? When I went to have myself tested it was only because my friend was doing it, and so I was not hundred percent prepared.” Veronica was only 26-years-old when she tested positive. Back then having HIV/Aids was something that people did not discuss openly because they were afraid of stigmatisation. For five years, Veronica not only lived with the fear of dying but also the secret that she was HIV positive. Not telling people also meant that she could not follow the procedures necessary to control the virus. Advice from counsellors to have her CD4 count checked fell on deaf ears because she had lost all hope of living and therefore did not see the need for it. In her head she considered herself dead already. Her intimate relationship suffered because she also kept her status from her partner, which put a strain on their relationship and he left. Losing her support system made everything worse and she started wasting away until the time when she met another HIV patient – a woman who opened her eyes to the truth and the benefits of disclosing her status. In 2010, she became a volunteer at AIDS Care Trust where she received more information on how to live with the virus. Becoming a volunteer motivated her to open up, because she knew that she would be able to move people more if she spoke from experience. From volunteering at the NGO, Veronica also found the motivation to have her CD4 count checked and she was put on treatment. “I am glad that I am now on medication because before I always feared that by taking the medication people would find out about my status since you have to take them every day,” she says. Through her story and experiences, Veronica now works as a Project Officer for Namibia Women’s Health Network helping other women who are going through what she went through (Windhoek Observer, 2014). 74

Interview with former nurse, Adonia Wienecke 1.For how long have you worked in the field of nursing? I started training as a nurse in 1973 and retired in 2013. 2.How many years have you dealt with HIV positive patients? 1992-2001: Professional nurse in charge of the Screening & STD/HIV clinic 3.What can you tell me about the behaviour of HIV positive patients? People living with HIV and AIDS express different types of behaviour, depending on the reasons for testing. They are mostly shocked and angry. After that the period of denial and disbelief begins. Post counselling sessionâ&#x20AC;&#x2122;s result in changes and acceptance sets in. This can take months of continuous counselling. 4.What were you´re duties working with these patients? Physical examinations; counselling; treatment of opportunistic conditions and referrals to doctors for problems outside my scope of practice. 5.What skill do you consider is the most important in this position? An empathetic persons; good listening and communication skills; verbal and non-verbal. Understanding the human behaviour during illness/ sickness and the ability to care for people. 6.What do you think hinders people from getting tested for HIV? Fear of the unknown; death; shame; mistrust. HIV is a sexually transmitted disease. Sex is still a taboo topic and people find it difficult to relate to it. People do not believe that medical staff will adhere to the confidentiality aspect of the treatment program. 7.Besides Antiretroviral therapy, what else do these patients need? Information and understanding about the spread; reinfection; diet; rest and a positive lifestyle. Counselling and the use of support groups is also essential.
76
PATIENT NEEDS
8.Do you have any suggestions for making it easier for HIV patients to get follow up care and support? Quality of education of health workers especially in their attitudes towards the people living with HIV and AIDS. Also educating the patients about the disease and the importance of using the facilities available. Centres should be conducive for caring and privacy and they should have friendly personnel. Furthermore, centres should be in reach of patients and should be a multipurpose institution. They should not be exclusive for HIV/ AIDS as this may create feelings of isolation and discrimination and will cause more stigmatisation. 9.What would you like to see improve in the field of HIV services in Namibia and what programmes would you suggest? Education is the key in managing and improving the services. Education of sexual health should start in the schools, universities and sport; newspapers and at home to prevent the contracting and spread of the disease. Furthermore, mobile clinics should be introduced in order to reach and to bring the services close to homes. 1st of December is World AIDS Day. That is not enough. Regular programs should be done by: TV – more programs, information pertaining to statistics, treatment, latest interventions like vaccinations; Sports – fun runs, billboards, T-shirts; Private sector – sponsor programs and donations for voluntary workers; Social media – facebook, twitter in terms of information on HIV/AIDS. (Wienecke, 2016).

Hospitals play a critical role in the delivery of HIV services, such as counselling, care and support, treatment, testing and the supply of medication. However, since the rise in HIV prevalence, the epidemic has put substantial pressure on an already strained health system. HIVpositive patients burden healthcare facilities and prevent access to care for other patients. Up to 55% of patients admitted into hospital can be HIV-positive. Hospitals are thus often overcrowded and patients have to wait hours in line before being attended to. Furthermore the roll out of HIV medication has put increased pressure on these facilities in terms of staff, storage space and laboratory capacity which is being constrained due to a shortage of buildings.

Types of HIV facilities The following illustrations depict the various health services found in Namibia: Hospitals A hospital is typically the major health care facility in its region, with large numbers of beds for intensive care and additional beds for patients who need long-term care.Currently Namibia has 47 hospitals throughout its 13 regions.
Health centers Health centers are a network of clinics staffed by a group of general practitioners and nurses providing healthcare services to people in a certain area. These centers are a lot smaller than hospitals but still provide a vast variety of services. Namibia has a total of 37 Health centers.
Clinics Clinics typically cover the primary healthcare needs of populations in local communities, in contrast to larger hospitals which offer specialised treatment. Altogether Namibia has about 248 clinics operated by the Ministry of Health and Social Services.
82
HIV SERVICES
Sick Bays A sick bay is a section of another organisation, such as a school or college used for medical purposes. These facilities are periodically visited by health workers to provide services. Many times these sick bays are facilitated in containers for their mobility.
Free standing VCTĹ&#x203A; HIV interventions that include both voluntary pre-and posttest counselling and voluntary HIV testing. People, of their own free will, opt for VCT, which provides them to explore and understand their HIV risks. These interventions often take place in temporary structures such as tents and relocate frequently. Mobile clinics Mobile clinics have a critical role to play in providing highquality, low-cost care to vulnerable populations that are living in remote areas. Depending on the routes they have to cover they need to be quite big and powerful.

Availability of HIV services in the health facilities The availability of HIV/AIDS services varies widely throughout Namibia. Almost all (98%) health facilities in Namibia have an HIV testing system. Nine in ten health care facilities in Namibia provide some care and support services for HIV. Most (81%) health facilities offer post-exposure prophy-laxis for health facility staff. 75% of facilities report that they provide PMTCT services. Other HIV-related health services are less widely available. Only 18% of facilities offer antiretroviral therapy (ART), which means they prescribe ART and/or provide medical followup services. Overall, HIV/AIDS services are more likely to be available in hospitals and health centres than in clinics or sick bays (Ministry of Health and Social Services 2009, 4).

Location Altogether, Namibia has 248 clinics, 37 health centres and 47 hospitals, most being in the larger cities and towns. Some clinics and health centres also have outreach points where health workers periodically visit to provide services. As a result 80% of the population now lives within 10km of a clinic. This still leaves 20% or over 300 000 people in remote areas, without ready access to health services (MCA-N, 2015). I want to focus on these remote areas, targeting people that live in rural communities. As this adresses the whole country, I will identify several sites which are spread throughout Namibias 13 regions.

PROGRAMME

The proposal will consist of 11 new facilities, composed of 1 central hub and 10 smaller modules.
Central hub The central hub will be located in the heart of Namibia, in the capital of Windhoek city. This facility will seek to provide comprehensive and quality treatment, counselling, education, prevention campaigns, testing as well as care and support for those already infected by HIV/ AIDS and the ones that are at risk. The building will contain a laboratory, sufficient counselling space, examination rooms as well as a big storage space for all the medication and vaccines. Seeing that there is a great shortage of qualified health workers in the public sector, this intervention will also offer educational programmes and training facilities to promote and foster existing as well as new health care workers and volunteers. All in all the central hub will serve as a supplier to all the smaller modules, providing them with qualified health staff, medication and maintenance support. Modules Each of the modules will be quite a bit smaller in size and functions compared to the central hub but they will retain the core services, which consists of spaces for treatment, counselling, care and testing, as well as accommodating staff members. These units will primarily focus on reaching out to rural communities. Each unit will be equipped with several mobile clinics, covering identified areas within the country. The whole masterplan will thus work as a site network, containing small integral parts that work together in order to try and reach everyone in need.

Branding of the buildings In order to draw as many patients as possible to the proposed buildings, the branding and their program becomes very important. HIV patients will not want to visit the institutions if they are called “HIV/AIDS clinics“. Rather than focusing exclusively on HIV/AIDS these facilities should allow for a broader program, inviting a diversity of patients . Branding the facilities as the “Center for disease control and prevention“, will merge HIV services with others, thereby drawing more patients to the building and at the same time disguising the HIV stigma.

Centers for Disease Control and Prevention The Centers for Disease Control and Prevention (CDC) is the leading national public health institute of the United States. The CDC is a United States federal agency under the Department of Health and Human Services, headquartered near Atlanta, Georgia. Its main goal is to protect public health and safety through the control and prevention of disease, injury, and disability in the US and internationally. Since 2002, CDC has helped Namibia develop and implement HIV/AIDS prevention, care, and treatment programs. CDC-Namibia helps build the capacity of the countryâ&#x20AC;&#x2122;s healthcare workforce. CDCâ&#x20AC;&#x2122;s assistance has strengthened national efforts to prevent HIV transmission and to expand care and treatment services. The aim of all support is to ensure that Namibia soon sees an AIDS-free generation.

Function: Before entering the building, visitors will be welcomed by an outdoor foyer and amphitheater, which allows for plenty of seating possibilities and shaded spots. This space will act as a buffer before proceeding to the registration and monitoring units, placed at the entrance of the building. Parts of this space could be used for events and functions. Characteristics: This area should be open for the public and well landscaped to create harmony with the surrounding context. Size and fittings: One big open space with a lot of trees, rocks, benches and lights Function: Patients must be identified, monitored, visit registers completed, and patient medical records folders retrieved and prepared (patient card/ID is opened). In addition, a simple symptom checklist should be conducted, focusing on the presence/absence of cough or new symptoms or illness to determine fast track procedures. Characeristics: This space should be right at the entrance of the building and close to the waiting area, privacy should dictate, records and registers should be kept in locked filing cabinets or shelves in a room that can be locked. Size and fittings: Provide several booths next to each other with desk space and two chairs, filing cabinets and storage. Function: Patients that need certain medicines, vaccines, examination or psychological help will need to wait in line. The space should provide comfort and a rational layout that links it to the services. Coughing patients with known or suspected TB should be separated and triaged for rapid evaluation to minimize their time waiting in crowded areas. Further, access to toilet and hand washing facilities should be in close vacinity as well as a play area for children. Patient education materials should be provided in waiting areas to enhance the patientsâ&#x20AC;&#x2122; knowledge and skills and to minimize boredom. Characteristics: These areas should be for all visitors, to avoid stigma. The space should be well-ventilated to control measures needed to minimize transmission of tuberculosis. If the climate permits, covered outdoor waiting space is preferred to enclosed indoor areas, include landscape and plants. Size and fittings: One big open roofed space with benches, educational displays, condom dispenser, water dispenser Function: The pharmacy will provide an open plan display of medication for self selection. These medications can be bought over the counter. Characteristics: The space should be light, public, well ventilated and allow for minimized movement for customers. Size and fittings: One open plan space with display shelves and a chashier counter. (World Health Organization, 2008)

Function: The collection and info counter will cater for prescription medication and guidance for patients. This area should have restricted access, especially for areas where narcotics and expensive items are kept. Inside there should be an additional secured area where narcotics and expensive items such as antiretroviral (ARV) medicines are kept. In addition this area will contain a counter space, a display area, an office as well as a big storage room. This space needs to be close to the garages and delivery area. Characteristics: Private, controlled temperature for the storage of drugs, controlled light as not too much sunlight is allowed to enter this space, secure space from inside and outside. Size and fittings: Small intimate public interface and a big open storage room with shelves and a sink. Function: The counselling rooms can be shared and should thus be flexible. The space is most useful located next to the clinical examination rooms. Space is required to support both group and individual pre-test information and post-test counselling. Characteristics: The space can be less formal and only requires a room for at least 3 people, protect privacy and confidentiality by good positioning within the facility, discreet signs, visual and auditory privacy. Light coloured walls as they are associated with positive emotions (Pressley & Heesacker, 2001). Natural light as it can support self disclosure, reduce the risk of depression and creates a more favourable impression of the counsellor, (Miwa& Hanyu, 2006; Pressley & Heesacker, 2001). Introduce nature, as it can increase comfort, mood levels, and overall attractiveness of office environments (Larsen, Adams, Deal, Kweon, & Tyler,1998). Size and fittings: 4-5 rooms with a minimum space of 3x3 meters. Not too small “claustrophobic feeling” and not too big as they create “insecurity”. Each room should be equipped with a desk, a few chairs, storage cabinets, a black board, wash hand basin, patient information materials Function: Experience shows that facility-based patient education and patient support groups can be highly effective means for providing pre-test information, support adherence, decreasing stigma, and transferring important ‘positive living’ skills. Characteristics: Big room dividable into smaller units, visual & auditory privacy, well ventilated, close to counselling rooms, flexible seating, connect to nature, warm and comfortable, avoid cold clinical atmosphere, calming environment, distractions should be limited Size and fittings: 1 big space for 20–50 people, the room should be equipped with loose furniture items to allow for flexibility Function: The space for contemplation should be an outside enclosed area, where patients can process their emotions and find guidance and psychological help if needed. Characteristics: This space should be a landscaped outdoor platform. It must be big in order to create privacy amongst visitors and have a close connection to nature. Size and fittings: 1 big landscaped terrain, fitted with benches, pathways, lights, small shaded spots, hubs, trees and shrubs. (World Health Organization, 2008) PROGRAMME

Function: In these rooms patients receive vaccinations and get examined for HIV. Most national guidelines recommend that patients with early HIV disease (‘pre-ART’) return for clinical assessments every 3 to 4 months, and that patients with advanced disease and those on ART return monthly until stabilized on treatment; then after that, every 3 months. Characteristics: Positioned close to the counselling rooms, visual and auditory privacy, views out to nature, avoid clinical feel, bring in a lot of natural light, well ventilated Size and fittings: 4-5 rooms with minimum space of 3x3 meters. A single clinical consultation room, fully staffed and dedicated to HIV services five days a week, can accommodate roughly 125–150 patient visits/week. The room should include a sink, a toilet for urine collection and a worksurface for rapid testing Function: Offices for the general practioners will serve to treat acute and chronic illnesses and provide preventive care and health education to patients. Characteristics: These offices will consist of simple small rooms, closed off to the public with visual & auditory privacy, well ventilated, close to the examination rooms and toilets, flexible seating, connect to nature, warm and comfortable, avoid cold clinical atmosphere, calming environment, distractions should be limited. Size and fittings: Two small rooms with a minimum space of 4x4 meters. Each room should be equipped with a desk, 3 chairs, an examination table and sufficient storage for the basic medical equipment. Function: Specialists will collect specimens from patients and perform tests to gain more clarity and knowledge about the sickness. Essential lab services are the minimum lab tests that should be done to offer comprehensive HIV services. These are: HIV diagnostics, Haematology, Venous whole blood collection and send-out for CD4 cell absolute count and for percentage, Blood sugar, TB diagnostics, Malaria diagnostics, Syphilis diagnostics, Pregnancy test etc. Characteristics: Clean, organised, clinical, should only be accessible by certain health staff, visual privacy from other departments in the building, close to clinical examination rooms Size and fittings: Large enough for all the equipment and staff required for the services. Function: Once patients have been diagnosed with HIV, they need to pay closer attention to their health. Good nutrition and exercise is thus important. The fitness studio will instruct patients on certain exercise routines and help AIDS patients regain their body strength. Furthermore the Studio will serve as an exercise platform for staff and students. Characteristics: Open and light double volume space with internal pool and seperate smaller units for private sessions with patients. There should be a close connection to views & nature. Size and fittings: The studio should be spacious and equipped with sufficient machines and weights. There must be at least one office for a fitness instructor and a receptionist.

Strategies to break the stigma The following illustrations explain various approaches how to prevent stigmatisation within and outside the building:
Signage HIV clinic
Family care clinic
Signage that is discreet, as well as clear and helpful. Patients are more likely to attend a facility labelled “family care clinic“ than one labelled “HIV/AIDS clinic“
Function of the building HIV+
HIV+
The buildingś function should not be exclusively designed for HIV/AIDS. Introduce another attraction and use to the centre. This will draw people in, that are not infected with the virus.
One Entrance and one exit Entrance Exit
By introducing only one entrance and exit point you avoid any seperation between visitors, customers and patients.
Communal rooms HIV+ HIV-
136
One pharmacy, one waiting area and one register. The use of a separate public areas for patients with HIV can run the risk that their HIV status may be disclosed in an involuntary manner.
PROGRAMME
Visual and auditory privacy Visual and auditory privacy - Rooms specific for HIV patients should be screened and sound proof to achieve complete privacy and comfort.
Secure medical records Medical records to be secured (visually, auditory & physically) to minimize accidental or involuntary disclosure of HIV infection. Colour-coding or obvious marks that designate HIV status on patient-held records
Room sizes Avoid spaces that are too big as they tend to create insecurity among patients. Introduce light partitions, screens or landscaping to break up the room and to create more intimate spaces where patients can´t be seen from every angle.
Confidentiality zoning Keep patients and customers a certain distance away from each other to avoid clustering of people thereby making visitors feel more comfortable.
PROGRAMME
137
Spatial intentions The following diagrams illustrate spatial characters that I would like to integrate into the facilities:
Multipurpose facility Introduce several functions to the buildings, instead of making it exclusive for HIV/AIDS. In this way stigmatisation and discrimination can be avoided and more people can be drawn to the facility.
Public and private The facilities should provide privacy to its patients and ensure that a personâ&#x20AC;&#x2122;s HIV status is not identifiable to others in any way. Public spaces should be open and high, whereas private spaces should be intimate, singular and closed off to the public eye.
C
A B
Circulation Create close proximities to make moving between A, B and C easy. The movement should follow a certain logic and should consider confidentiality between visitors and patients.
Entrance A communal main entrance should be provided. From that point visitors will be guided towards seperate departments. This aims to avoid stigmatisation and allows users to interact with each other.
138
PROGRAMME
Flexibility
A
B
Introduce flexible layouts and areas, which may accommodate different functions. Avoid rooms that are not used for a period of time. The structure should be built in a way that it allows for future extensions and for disassemble and mobility.
Communal rooms Different spaces and departments should share communal areas. These areas and public spaces should encourage social relations between users.
Pause spaces Extend the public areas with spaces more suited for privacy.
Waiting areas Patient waiting areas should be open and well-ventilated as this is a key element of the environmental control measures needed to minimize transmission of tuberculosis. Covered outdoor spaces are preferred to enclosed indoor areas.
PROGRAMME
139
Spatial intentions The following diagrams illustrate spatial characters that I would like to integrate into the facilities:
Confidentiality Avoid creating an impression of being watched. Patients need to know that they can trust the health workers, only then will they feel comfortable.
Courtyards Courtyards and visual as well as physical links to nature should be introduced to draw sunlight into the building and to avoid a clinical atmosphere. They also serve to provide better ventilation and security.
Intimacy Spaces such as counselling rooms or treatment and testing departments should be divided into smaller units, in order to maintain an overview and a sense of intimacy.
Zones Division of rooms into different coherent zones in order to create more privacy within a space.
140
PROGRAMME
Spaces for contemplation Introduce spaces for patients where they can reflect on life and their health in a spiritual atmosphere. This should help them on their path of acceptance of their status.
Information Provide educational information and materials throughout the facilities, especially in waiting areas in order to enhance the patientsâ&#x20AC;&#x2122; knowledge about the virus and to minimize boredom while waiting.
Sunlight Introduce sufficient natural light into the buildings. This will improve health and well being of patients and staff and reduces cost of artificial lighting.
Open staff rooms The rooms for staff members should encourage exchange of information among each other. The work areas should be team based - no few personal offices.
PROGRAMME
141
Visions Adaptation Designing Architecture for HIV patients needs to be flexible and adaptive because of its dynamic organisation of services and spaces. High client loads increase the spatial challenge. More people come if services are made available. This demands a facility that can receive substantial client flows. In addition, the architecture should envision a sustainable and feasible approach, making use of affordable local materials and building techniques, that blend into the surrounding context. The result should realise a building which is adaptive in its spatial qualities as well as its structural aesthetics.
PROGRAMME
142
Intimacy In order to avoid stigmatisation and discrimination, these facilities will have to provide patients with sufficient privacy and confidentiality. They will thus not be developed exclusively for HIV/AIDS, but rather as Centers for disease control and prevention, where the public can receive a whole range of medication , vaccines, health education and counselling. The HIV services will thus only become a smaller part of the whole building, which will be kept confidential in intimate spaces, making patients feel more relaxed and secure. The aim is to draw a diversity of patients and visitors to these centers, and thereby disguising the HIV stigma.

THE BRIEF
149
HIV, the virus that causes AIDS, is one of the world’s most serious health and developmental challenges. Since the onset of the epidemic in the 1980s, more than 70 million people have been infected with the virus and about 35 million people have died. Currently about 36.7 million people are living with HIV. The burden of this epidemic continues to vary considerably between countries and regions. Sub-Saharan Africa remains most severely affected, with nearly 1 in every 25 adults infected, accounting for nearly 70% of the people living with HIV worldwide. Namibia is one of those Sub-Saharan countries highly affected by the virus. It currently has the 5th highest HIV prevalence rate in the world, with a total of 13,3% of the population infected. This has drastically impacted on the countries health indicators, posing serious developmental challenges. Providing universal access to HIV services and infrastructure, has been a priority for the Namibian government for the last ten years and the country has shown that achieving a massive scale-up of HIV services in a short period of time is feasible, given sufficient political commitment, social mobilisation and financial investment. One of the organisations providing financial support towards the HIV epidemic in Namibia is the CDC (Centers for Disease Control and Prevention). The CDC is a United States federal agency under the Department of Health and Human Services, headquartered near Atlanta, Georgia. Its main goal is to protect public health and safety through the control and prevention of disease, injury, and disability in the US and internationally. Since 2002, CDC has helped Namibia develop and implement HIV/AIDS prevention, care, and treatment programs and assisted in building the capacity of the country’s healthcare workforce. CDC’s support has strengthened national efforts to prevent HIV transmission and to expand care and treatment services. The aim of all their support is to ensure that Namibia soon sees an AIDS-free generation. CDC is now proposing to accelerate this aim, by means of new architectural interventions that will seek to provide comprehensive and quality treatment, counselling, prevention campaigns, testing as well as care and support for those already infected by HIV/AIDS and the ones that are at risk.
150
DESIGN BRIEF
Seeing that Namibia is so sparsely populated, these centers should focus on the rural communities, as most of them have little access to health services. Since this adresses the whole country, the proposal will have to consist of a masterplan, introducing several interventions, spread throughout Namibia´s 13 regions. In total there should be 11 new facilities, composed of a central hub and 10 smaller modules. The central hub will be located in the heart of Namibia, in the capital of Windhoek city. It should contain a laboratory, sufficient counselling space, examination rooms, a clinic, GP offices, a pharmacy as well as a big storage space for all the medication and vaccines. Seeing that there is a great shortage of qualified health workers in the public sector, this intervention will also have to offer educational programmes and training facilities to promote and foster existing as well as new health care workers and volunteers. All in all the central hub will serve as a supplier to all the smaller modules, providing them with qualified health staff, medication and maintenance support. Each of the modules will be quite a bit smaller in size and functions compared to the central hub but they will retain the core services, which consists of spaces for treatment, counselling, care and testing, as well as accommodating staff members. These units will primarily focus on reaching out to rural communities. Each unit will be equipped with several mobile clinics, covering identified areas within the country. The whole masterplan will thus work as a site network, containing small integral parts that work together in order to try and reach everyone in need. Apart from the necessacity and function of these facilities, the architecture should envision a sustainable and feasible approach, making use of affordable local materials and building techniques.

Merge and compress wings with cores In order to reduce the building all the wings and cores are shifted into the same axis. This allows for a cleaner transition of functions and for a more feasible structure.
172
DESIGN STRATEGIES
Shift building blocks out of the grid Seeing that the structure will have to be built on several other sites, it is important to create flexibilty. By means of maintaining the structural layout, building blocks can simply be rotated and shifted according to the perimeters and the topography of each site.

DESIGN CONCEPTS
177
Human scale The bigger the space the more insecure patients will feel. Buildings such as counselling rooms or treatment and testing departments should be divided into smaller units, in order to maintain an overview and a sense of intimacy.
Spread buildings The site is big. Make use of it. Building blocks that require privacy should be scattered in order to achieve visual and auditory privacy.
Open waiting areas Reduce possibility of contamination. Patient waiting areas should be open and well-ventilated as this is a key element of the environmental control measures needed to minimize transmission of tuberculosis.
Nature as a buffer Break the clinical atmosphere Courtyards and visual as well as physical links to nature should be introduced to draw sunlight into the building and to generate a visual barrier from building to building.
178
DESIGN CONCEPTS
Screens Now you see me, now you dont. Introduce natural timber screens wherever privacy is needed. This will make patients feel more comfortable while allowing light to penetrate into the interior.
Walkways Roaming through nature. Long outside walkways are introduced throughout the project. This allows users breathing space and closer connection to the landscape.
Contemplation spaces Time to process. Pause spaces will be designed along the walkways. These will allow patients to reflect on life and their health in a spiritual atmosphere. This should help them on their path of acceptance of their status.
Regulating patient flow One at a time. In order to avoid too many patients at once, the number of people will be regulated. This will make patients feel more comfortable and minimize the chances of contamination.

Gabions The walls for the two core structures will be constructed with gabion walls. Due to their big thermal mass they can resist heating up too fast and, storing the energy absorbed from the sun and releasing it over time. The rocks used for the infill will be sourced locally from the site and its surroundings. The construction can be performed by the locals as it doesnt require skilled labour.
Salvaged cladding Salvaged and reused material such as corrugated sheeting, timber palettes, wooden boarding and shutterboard will be used for the exterior wall cladding of the lightweight steel wings. Furthermore all the suspended walkways will be covered and laid with old timber planks, running adjacent to the length of the path.
Glass Openings for the public spaces will be installed with low E glazing in order to achieve visibilty where its needed. The trombe walls facing North in all the lightweight steel wings will also be cladded with glass in order to reach its passive solar heating.
Latte Timber latte (poles) are a very commonly used building material in Namibia. I want to use these poles as screening devices as well as a shading instrument for walkways and parking. The spacings of the individual poles will vary according to the the function and its privacy. Other than that the latte will give the building a natural layer linking it to the natural surroundings.

MATERIAL COLLAGE
Canvas The roofs of the cores will be covered with water repellent ripstop canvas. I wanted to find a method how to save added matrial for a substructure and thereby needed a lightweight and flexible material. The canvas allows for minimal steel support and it protects against rain and sun. The sheeting also allows for diffused light to enter the interior.
Nano fiber filter screens The sides of the canvas roof will be fitted with another type of fabric, which will be a nano fiber filter screen. This material keeps out most of the unwanted dust particles and insects but retains air flow throughout the building. More than that it allows for light to penetrate into the interior, reducing the need for articial lighting and ventilation.
Steel frames Seeing that the building needs to be economical and feasible, the structure will be built out of lightweight steel frames. These will allow for pre manufacture and easy assemble on site. Other than that this modular steel layout can easily be erected on another site and extended when needed.
Polycarbonate sheeting All top level windows in the wings will be filled with translucent polycarbonate sheeting in order to save costs on glass. The sheeting will retain the required light intake. Seeing that these windows are installed under deep overhangs, the sheeting will not be exposed to direct sunlight, thus preventing it from turning brittle, and extending its life span.
