INTRODUCTION
COURSE OVERVIEW PROJECT DESCRIPTION
PEDAGOGICAL STATEMENT
“Advocate Christ Medical Center, located in Oak Lawn, is a recognized leader in the medical community and one of the major tertiary and quaternary referral hospitals in the Midwest. This premier teaching institution excels in a variety of specialties including neurosciences, oncology, pediatrics and women’s health. One of the largest and most comprehensive providers of cardiovascular services in Illinois, it’s nationally renowned for its advanced procedures in the treatment of heart disease, heart failure and stroke. Christ Medical Center shares its campus with Advocate Hope Children’s Hospital—the only freestanding children’s hospital in Chicago’s south and southwest suburbs.”
Partum units; mechanical floor(s); and a bridge or tower connection to a new parking structure across Kostner Street. Conceptual design work used to inform the comprehensive design work to include: connecting to the existing hospital main entry/lobby (possible winter garden); the new parking structure across Kostner Street (possible green wall); and a new link connection to the future second floor NICU The new Patient Care Tower will add approximately 308,000 BGSF to the Advocate Christ Medical Center in the South Patient Tower. The new Patient Care (ACMC) campus. The building will most likely comprise seven inpatient floors. There will be a total of 183 Tower will be located in close proximity to the existing private patient rooms in the new tower. For this studio, only the following programmed spaces will be the East/West and South Patient Towers and will need to responsibility of the student to design comprehensively: the labor delivery / recovery suite and 28 bed Post address several issues around connectivity as well as circulation of patients, materials and staff.
Neighborhoods function as nodes in the larger network of the village and city. Without top-down master planning, neighborhoods can be an inefficient piece of their ecosystem and allowed to under-serve the whole. Presently, the inter-relationships of the neighborhoods are a symbiosis that allows competition and exploitation. The political, social, and economic factors that divide a village or city into parts are reflected inside their individual neighborhoods. Political and commercial factors divide neighborhoods into lots. Private ownership of the lots habitually ensures that distinct parcels will passively contribute to a neighborhood’s ecosystem.
Evidence-based design and biophilic design principles will be used to guide the experiential design process. This studio will rely heavily on handmade physical models as a tool for understanding the experiential quality of the patient rooms and patient tower. Students will be expected to read and discuss various articles and book excerpts relating to the studio design process. Each student is responsible for the programmatic and comprehensive building design on site 1 below (limited to public functions, i.e., lobby and its support functions, maternity services, building cores and shell, and mechanical and electrical services).
The idea of a neighborhood acting as a network implies consensual function, which implies co-ownership. Sharing natural resources, such as rainfall, daylight, and wind, requires the same top-down planning that could guarantee neighborhoods actively benefiting a city’s “biome”. Unlike the gorilla-style commandeering of vacant land in a city to force mutualism in an area of disinvestment, in a campus setting, individual ownership can self-propagate mutualistic and commensal relationships between lots of diverse function - even between discrete parcels of land.

Lots within a neighborhood can become nodes within a network. This possibility usually remains outside the control of the architect unless they are working with communally owned properties or individually owned campuses. If prominent, lots in a neighborhood that are brought together to be nodes linked by ties, though invisible, will promulgate an urban network paradigm. Accelerating this pattern shift requires recognition. Recognition is commensurate to the organism and its organization.
CONCEPT DESCRIPTION In Evidence Based on Design, there are many ways to design medical center for not only the patients, but also the staff, such as making a home-like environment, ease of way finding, getting even natural light into the building, and biophilic design. In my design, in order to accomplish E.B.D, the main concept of the new patient building focuses on communication with users, communication with its neighborhood, and communication with nature. This “healing way”, uses the outdoor greenery spaces that are surrounding the building to attract natural light into several small atriums of the building, and articulates a dynamic building shape. The atriums become a “sign” to help people easily find their way. Each floor is connected to green spaces either horizontally or vertically within tow or three story high gardens. This means that each patient room can have equally good view and intimacy with the nature, even though they do not have the same orientation. Also, the bridge between the parking garage and the new patient building becomes a promenade for patients, staff, and the neighborhood. In addition, the Advocate Christ Medical Campus surrounding the parking lots would use as a place for wildlife through the biophilic design. The healing way starts from new park in front of the parking garage, and would be continuous along the west side of the parking garage and its roof garden, and finally connects with the winter garden. Lastly, the “healing way” including the arcade and several atriums would be the center of the whole Advocate Christ Medical Campus. 2012 SUMMER STUDIO

SITE ANALYSIS
PROBLEM SEEKING & SOLVING Oak Lawn is a village in Cook County, Illinois, United States. The population was 55,245 at the 2000 census. Oak Lawn is a suburb of the city of Chicago, located southwest of the city. It shares borders with the city in two areas, but is surrounded mostly by other suburbs Oak Lawn is known for its community hospital, which serves the residents of Chicago and its suburbs. Christ Community Hospital (now known as Advocate Christ Medical Center) was built in Oak Lawn in 1960 and has expanded with the development of Hope Children’s Hospital, along with becoming a part of Advocate Health Care. Christ Hospital also has a state-of-the-art Level 1 trauma center, providing trauma patients with advanced emergency medical care. The emergency department treats more patients than any other hospital in Illinois. Now, the medical campus is surrounded by huge parking lots. Also, there are a few vegetations around the site. Thus, it is difficult to get nice view from patient tower. Also, making a public space that has close connection with nature is very difficult. We have two strategies to solve current site problems. Firstly, we make heavy vegetation on the parking garage. By that, entire campus can get a visual advantage from vertical vegetation. Also, we make vegetation path (it called healing way) that surround patient tower, will make good spaces that connected with nature.
SEEN & UNSEEN CONNECTION There are some design factors that will make connection with existing buildings and community. Firstly, urban farm on the top of parking garage will give visual advantage for patient tower. Also, patients can get fresh vegetables from urban farm. It can provide job opportunity for community too. 2012 SUMMER STUDIO

PATIENT ROOM DESIGN

PATIENT AREA FAMILY AREA NURSING AREA Figure 1. Concept Sketch
CONCEPTUAL DESIGN The reason why we tilt the shape of patient room is to control visual direction to the parking garage. Also, the shape gives feeling of the space deeper that makes spatial quality higher. Dark wood flooring makes cleaners detect dust on the floor easier so that the patient room can keep clean. Bright color wood for furniture is helpful to make the atmosphere of the room likes home, so patients feel the hospital familiar. Some parts of wall are painted with healing color that gives psychological help for patients.

EVIDENCE BASED ON DESIGN
Figure 3. Patient Wall
Evidence-Based Design in healthcare is an extension of the theories of evidence-based practice and evidence-based medicine. Evidence-based medicine stems from Professor Archie L. Cochrane’s premise that much “evidence” for best practices for medical treatments and interventions is available in the form of relevant randomized controlled trials. He strongly advocated that this evidence should be collected, analyzed, validated and then widely disseminated. 6

Larger size of window let more daylight into the room that reduces depression of patients. Vertical vegetation on the parking garage gives distant view of nature. Also, healing way gives closer connection with nature. Both of factors can reduce pain and stress of patient. Home-like furniture, such as bed and sofa, makes patient room more familiar that improves patients’ sleep. Also, dark color floor diminish hospital acquired infections.

ADJACENCY DIAGRAM
Conceptual Section Design This section study drawing shows the concept of a sunken garden and daylight studies. The sunken garden, which has step benches and oak trees, gives a large exterior green park for patients, staff, and public. Additionally, the sunken garden gives more intimate connection between the new tower and the existing buildings. A pond in the sunken garden that combined with dining space can acts as a light reflector which makes the underground dining space bright. Also, the atrium as 9 stories height on north side is another factor that lets light and nature into the building.

Third floor is for LDR. Staff area for LDR is located on the center of the floor that makes staff work more efficient. Also, decentralized nurse station Improve the quality and safety of healthcare. Every patient room is arranged in same direction that reduces medication errors. Surrounding healing way is combined with not only patient area, but also staff area. Thus it makes high quality nature-integrated space for patient, family and staffs.

EGRESS SYSTEM AND ACCESSIBILITY 5.1 Exit Access Paths Group I-2 Institutional Medical and Custodial Care Occupancies have special exit access requirements reflecting the needs of occupants who in many cases may be incapable of moving themselves to safety in the event of a building fire. See the code for details. For emergency escape and rescue requirements for residential occupancies. Egress Through Adjacent spaces :In their most conventional configuration, exit access pathways are expected to proceed from rooms to corridors and then to exit. The International Building Code in most cicumstances also permits exit access pathways to flow through intermediate spaces to whichthe originating space is functionally related.
