Wildwood Farm is meant to be a place of novel engagement with surroundings—not only within nature on the farm itself, but also with the bordering development areas. In order to accomplish this, we are proposing a botanical garden and recreation trails for the front three pastures of the farm. This zone will create an experiential threshold between the program of the farm and the residential areas to the east. This shaded ‘pasture’ for human leisure will be just as managed as the grassy pastures for the horses. Used as both a productive, working landscape and an educational resource, the botanical garden will stay true to definition “holding documented collections of living plants for the purposes of scientific research, conservation, display and education” (Botanic Garden Conservation International). Located within this zone, the Big Barn landmark and the entrance onto the Wildwood property are the main hubs of traffic, both vehicular and pedestrian. The entrance onto the property is a continuous, scenic drive that recognizes the landforms while still designating a path from entry to facilities in a timely manner. While driving towards the facilities on the farm, the visitor experiences framed fragments of nature specific to the speed of the car and will be encouraged to come back to the places they have passed to slow down and enjoy them in other ways. The Big Barn will house educational ‘think tank’ space as well as boarded horses— engaging those within it by reminding them what the legacy of this farm is. There will also be a farm to table restaurant, utilizing the botanical garden as a resource for locally grown foods and community gatherings. The Botanical Garden will also be used for the nutrition and breeding facilities on the north side of the property in order to grow the food and plants necessary for these programs. Both the hospital and the rehabilitation center are organized to best frame the views of open pasture and existing landscape. By making the pastures the focus, the green landscape with vast expanse and definitive beauty will convey the continuity and nurturing devotion that is part of the farm’s legacy. The incorporation of this pastoral presence will provide therapeutic experience for both people and horses alike, easing tensions and returning them to a place of the past—a green space with the patience of the earth under the shelter of the trees. Because of the inwardly focused nature of the hospital program, a beacon of glass sits on top of the structure, allowing the users of this building a way to experience a calm and generous view of the landscape that is not possible or is not feasible in other parts of the building. The rehabilitation center is dedicated to creating relationships between the indoor and outdoor space, blending the two with thoughtful connections between program. Covered areas mix well with conditioned ones, emphasizing the gravitational pull into the pasture that will help the horses to heal and allow them to find balance with nature. The project is also connected out the southea st corner by a set of steps that lead to a natural pooling site that has been constructed to retain more water than is naturally there so that the pool stays filled and can become an oasis for hospital workers and clients alike. Elevations in landforms and natural drainage patterns create this pool for conversation and peaceful walking—a draw for both neighbors and visitors.

part i Design

STRUCTURE The material palette of this project is particularly important. In order to maintain an equine aesthetic as well as the aesthetic of Wildwood Farm, we are proposing a palette modernizing what is already existing in structures on the farm while still speaking to the rawness and clarity of certain materials. Wood, concrete, and steel will be the main structural materials used on the project. Using steel as the main structural element, the project will be able to accomodate spaces of differing heights and spans. Following a structural grid, the steel beams and columns will define space while still maintaining the ‘floor clearing’ and ‘exposed structure’ qualities of the wooden Big Barn. Concrete shear and load bearing walls will support the steel structure where more defined spatial separation is needed. Along the perimeter, the steel structure will begin to define a largely spaced mullion pattern giving the building large unobstructed views, specifically to the west and north (towards the main pastures and the Big Barn). The eastern and southern walls will be restricted by the concrete system, allowing for a much more specific designation of punches to the outside. This will not only direct views, more specifically, to engage with designated elements of the landscaped areas, but will also limit the exposure of the building to the sun’s harsh rays from the south.

LIGHTING The lighting strategies of this project will create distinct qualities of light within different parts of the program to better differentiate the aspects of the project from each other, as well as celebrate the pastoral landscape of the site through its access to daylight. The upper floors of both the hospital and rehabilitation center have the most access to daylight. Since these spaces are both viewing galleries and library spaces, it is important to have daylight for both visibility and diffuse lighting for lower floors. Both of these spaces will also light up like glowing boxes in the landscape at night, celebrating the place with artificial light lifted above the ground, floating. Within the hospital, both natural daylight and artificial light have equal importance. It is necessary to have extreme control of lighting in the surgery suites and prep room for both accuracy and visibility. This light will be enhanced by the diffuse natural daylight from the viewing galleries above.

Rehabilitation Foundations Plan | 1” = 50’

The stalls will have access to daylight through the window openings that look out onto the landscape, providing fresh air and light to those that need it, and the possibility of closure for those that need extreme control of their environment. Skylights will provide daylight for specific areas in the hospital, specifically the large corridors through which the horses are led and are lined by offices. These skylights will provide light were it is difficult to reach inside of the building and will improve the experience of passage. Along the entry side of the hospital, glazing provides views to the constructed landscape as well as daylight for the nurses and exam room areas. This glazing also provides views and lighting for the offices along the north side of the building and the reception and conference room areas. The south walls of the hospital will be thick massing walls in order to help with heat gain and certain places of privacy. These walls will have large window punches in them for light and distinct views of landscape. The windows will be set back into the wall, creating deep voids in the massing which will provide much needed shadow at this orientation. Overhangs around the outside of the building will provide shade and places of rest on the exterior of the envelope. These places will encourage people, both clients and staff, to appreciate the landscape and provide spaces for rejuvenation and peaceful thought. Roof overhangs on the second level will provide space to enjoy the sod rooftop and views of the landscape. Overhangs on the ground floor will provide space to engage with that landscape in different ways. Some of these shaded areas will provide circulation and access to the building on the ground floor. These areas will use material patterns to project shadow onto surfaces, creating distinct speeds and spaces along exterior routes. The rehabilitation center has been designed to use natural light to its greatest advantage. Large openings between interior and exterior celebrate the access to the natural world and its inherent healing qualities. Operable walls will play on the same material patterns of the overhangs in the hospital. These patterns will create distinct experiences in different programmatic areas. Clerestory openings in both the arena and the free walk create distinct lighting conditions with western light. Since the roof of this building acts almost as a pavilion, covering the program within, it creates a shadowed interior with deep recesses that mimics the Big Barn on site. In cooler temperatures, electric infrared heaters will be used, creating a visibly warm glow within the space it is heating. Artificial light will be used specifically in the community education areas and the exam rooms, places where both visibility and accuracy are necessary to the programmatic requirements. At night, the indoor/outdoor spaces will dimly glow with the light of a front porch, distinct from the landscape, but still a part of it. Rehabilitation First Floor Structural Framing | 1” = 50’

HVAC The HVAC considerations of this project are founded on the idea that there could be less equipment, lower costs to the owner in the future, and sensitive use of the existing site qualities and parameters. The main HVAC system in both the rehabilitation center and the hospital will be an underground geothermal heat pump system. The loops will be buried under the parking and constructed landscape of the courtyard between the two buildings. The loops will connect to the buildings in heat pump rooms where the air will be heated and cooled and sent out through the building in a VAV reheat system. This will not only give a high level of control over the entire system, but will also provide clean air to all areas of the hospital and rehab center, avoiding disease and infection as well as stale air. Mechanical space has been provided for each heat pump room. In the hospital, there is also a fan room for even more control of the systems for the surgery zone. This area has extreme control importance and is highly mechanically powered. The surgery rooms must be maintained at highly specific temperatures for different periods of time. The necropsy hallway and teaching areas must also be specifically controlled and contain two large coolers which also need a high level of power and control. The fan room will give extra power and control in addition to the heat pump system. It will still use the loops from the ground, heating or cooling air to distribute to this zone. The rehabilitation center has been designed to create relationships between indoor and outdoor space, re-adjusting the horses to their natural habitat and creating communion between horse, building and landscape. Because of this system, the heat pump zones for this building are limited. There are two main conditioned zones for this building (one on the far south end and one on the far north east). Both of these zones are controlled because of their specific programs (community engagement and exam rooms). Most of the duct systems are exposed and are designed to flow through the buildings in ways which enhance the spaces below them, not only in maintaining air flow but through mimicking movement, introducing a ceiling plane, and providing an industrial and raw aesthetic which converses with the material palette of the project. In order to better control the rest of the environment, there are passive systems used, specifically, in the rehabilitation building which will maintain better control of the space. Some of these include electric infrared heaters, operable walls and windows, stack ventilation over the hay storage and waste management areas, and Big Ass Fans in the arena. Both buildings have large flat roofs which will be used as both sod roof and for PV installation. The PV will be used to power as much of the buildings as possible and will provide a powerful combatant against the cost of running such a highly-powered hospital and rehabilitation center. The isolation facility for the hospital will be run on its own ventilation involving HEPA filters and other contagion controls systems. The ventilation for this portion of the building will be directed towards the open landscape, away from the main hospital building.

Measure 1_Design for Integration This project is affiliated with the University of Tennesseeâ&#x20AC;&#x2122;s Equine Center. They are proposing a development of Wildwood Farm in South Germantown near Memphis, TN. The center is located on a site that as a historical polo horse community on 350 acres of land. In order to preserve the legacy of the site, the client has asked for UTK to develop an educational and equine research hospital on the property. The goal here is to preserve and enhance the site by designing for the environmental value and the social and economic aspects while considering what is best for all clients â&#x20AC;&#x201C; human, creature, and environment.

Measure 2_Design for Community hAs part of the community, this design will encourage interaction between the UTK community and the developing suburb surrounding the property through a productive landscape and botanical garden. The project will be enhanced by this engagement through allowing new modes of discourse and education about horses as well as provide a lively and enjoyable space for owners, staff, and students on the property. The botanical garden will provide landscape for production in relationship with the nutrition and breeding center as well as a community space for the area within the historical Big Barn.

Measure 3_Design for ecology Minimal site disturbance and manipulation is very important to provide valuable sustainable habitats for all creatures. The horses require large amounts land space, water, and nutrient enriched grass. The buildings are locaed on the site at the highest and flattest elevation to avoid large amounts of exaction. The location of the buildings are also in close proximity to avoid ecology disruption for the other species that migrate this pastoral property. All earth removed will be used to construct the experiential courtyard between the buildings and to the south of the hospital. A heat pump system will be installed in order to produce less pollutants. Water will be redirected around and through the buildings to retention areas and a main rain garden at the lowest point of the property in order to create space for people to engage with ecology safely and develop new ecologies within the retention areas.

Measure 4_Design for Water This project considers trategies in which emphasize the control and retention of water or ecological and recreational use. Controlling storm water is an enormous responsibility on this expanse of flat land. The land is designated as a floodway. The buildings are located at the highest and flattest elevation and adjacent to steeper sloping elevations in the landscape with natural drainage patterns creating the opportunity for a beautiful oasisâ&#x20AC;&#x201D;its beauty drawing both neighbors and visitors, creating a pool for conversation and peaceful walking. Retention areas in both courtyards provide another level of water containment wihtin the drainage pattern for the main retention area to the south. Gravel parking and roads will help to keep water from pooling and reduce runoff. Both buildings have green roofs, some occupiable, that will help to filter as well as drain water more slowly off the roofs to retention pools in the landscape below.

Mesure 5_Design for Economy Resources are a concern and the Life Cycle Cost Analysis should help select materials and equipment. Reducing building size as well should be considered only if done with specific intent, otherwise it could be a mistake for future development. This type of response needs to be general so that cyclical and continual developments in horse research and rehabilitation can be implemented. As conventions change, the design needs to change with it.

part ii AIA COTE Measures Measure 6_ Design for Energy In order to regulate spaces for the horses, there needs to be very specific control and ventilation for their air quality and comfort, which will affect energy strategies. Temperature plays a huge role when designing for these programs. Waste management and maintenance of the horses are also involved in the energy input and output of the projectâ&#x20AC;&#x201D;specifically energy strategies of dealing with consumption as well as processes. Air locks and temperature differences were studied and considered and resulted in unconditioned spaces being located at the north end of the rehabilitation building allowing for passive cooling and avoiding southern exposure. The waste management of the facility should be incorporated with the development and maintenance of the botanical garden on the far west and far east sides of the property, i.e. using waste as fertilizer.

Measure 7_Design for Wellness Access to daylight and good ventilation are priveledged on this site. Ventilation has to be developed in order to cycle air in the most intentional way in response to close proximity of sick horses. Programs are oriented towards the expanse of landscape and placed along the exterior in order to provide access to daylight for specific tasks. Horses respond to daylight and access to nature in the same way humans do. There are proven studies that promote this type of biophillic design in both horse and human research. There is also a wellness factor that needs to be designed in regards to the community through outdoor exposure, botanical gardens, and trails throughout the property. Our focus should not only be on the horses, but also on the people who are using this facility.

Measure 8_Design for Resources This project concentrates construction n one area of the site so that transportation of goods does not affect the whole of the 350 acres. There are few trees on the building site so there would be little opportunity for reuse of those materials, but they could potential be invcorporated into the project as part of the construted landscape.

Measure 9_Design for Change This project responds to the test of time and ways that the buildings will remain useful for years to come. Considering the amount of change and flexibility this healthcare facility may need for the future we are proposing a grid system with enough flexibility to allow for future changes if needed. With airy spaces and high, exposed ceilings, the buildings project a sense of nostalgic placelessness, an oxymoron that allows for it to feel like it belongs on the property but does not restrict its use to its original program, even for the hospital.

Measure 10_Design for Discovery By analyzing the engagement of the traditional community with the equine community and their sidelong developments, we could understand the impact this project would have on the area both demographically and culturally.

The material palette of this project is particularly important. In order to maintain an equine aesthetic as well as the aesthetic of Wildwood Farm, we are proposing a palette modernizing what is already existing in structures on the farm while still speaking to the rawness and clarity of certain materials. Wood, concrete, and steel will be the main structural materials used on the project. Using steel as the main structural element, the project will be able to accomodate spaces of differing heights and spans. Following a structural grid, the steel beams and columns will define space while still maintaining the ‘floor clearing’ and ‘exposed structure’ qualities of the wooden Big Barn. Concrete shear and load bearing walls will support the steel structure where more defined spatial separation is needed. Along the perimeter, the steel structure will begin to define a largely spaced mullion pattern giving the building large unobstructed views, specifically to the west and north (towards the main pastures and the Big Barn). The eastern and southern walls will be restricted by the concrete system, allowing for a much more specific designation of punches to the outside. This will not only direct views, more specifically, to engage with designated elements of the landscaped areas, but will also limit the exposure of the building to the sun’s harsh rays from the south. Because we would like to leave the structure exposed while retaining a high fire-resistance rating, it would be appropriate to explore types of fireproofing materials or coatings for the steel structural columns when exposed. All of our steel should be 15’ or more above the ground floor so this would be something to consider in exposing the systems needed if we chose steel for the roof structure. Because we are designing a hospital/laboratory, a common structural system for this type of building would be steel beams and girders, open-web joists, or trusses. In order to impact the site less, the building will be constructed using prefabricated steel beams, columns, and girders. Because we are using a conventional steel frame, lateral stabilizing elements are required. Site cast concrete shear walls are used for this reason. Open-web steel joists are used for the longer roof spans in the arena spaces since they are lighter weight than the conventional steel system. They will also give the arenas a lofted, airy feel. The foundations of the structure are spread footings, isolated and wall. These concrete footings attach to the steel columns which hold up the main floor and second floors. The beams and columns follow a grid system--15’ apart east-west and a tartan grid north-south. The longest beam span is 30’ and the shortest is 15’. The grids cross both buildings, lining up the rehabilitation with the hospital providing distinct exterior communication between the two through structural expression.

By comparing the model throughout the process of development, it was easier to see how and where our model was deficient as well as what pieces of the project could affect the energy consumption of the buildings. Things like roof and wall R-values, Window to Wall Ratio, and Shading controls were major considerations in the continual development of the project.

Peak Heating Comparison

The HVAC considerations of this project are founded on the idea that there could be less equipment, lower costs to the owner in the future, and sensitive use of the existing site qualities and parameters. The main HVAC system in both the rehabilitation center and the hospital will be an underground geothermal heat pump system. The loops will be buried under the parking and constructed landscape of the courtyard between the two buildings. The loops will connect to the buildings in heat pump rooms where the air will be heated and cooled and sent out through the building in a VAV reheat system. This will not only give a high level of control over the entire system, but will also provide clean air to all areas of the hospital and rehab center, avoiding disease and infection as well as stale air. Mechanical space has been provided for each heat pump room. In the hospital, there is also a fan room for even more control of the systems for the surgery zone. This area has extreme control importance and is highly mechanically powered. The surgery rooms must be maintained at highly specific temperatures for different periods of time. The necropsy hallway and teaching areas must also be specifically controlled and contain two large coolers which also need a high level of power and control. The fan room will give extra power and control in addition to the heat pump system. It will still use the loops from the ground, heating or cooling air to distribute to this zone. The rehabilitation center has been designed to create relationships between indoor and outdoor space, re-adjusting the horses to their natural habitat and creating communion between horse, building and landscape. Because of this system, the heat pump zones for this building are limited. There are two main conditioned zones for this building (one on the far south end and one on the far north east). Both of these zones are controlled because of their specific programs (community engagement and exam rooms). Most of the duct systems are exposed and are designed to flow through the buildings in ways which enhance the spaces below them, not only in maintaining air flow but through mimicking movement, introducing a ceiling plane, and providing an industrial and raw aesthetic which converses with the material palette of the project. In order to better control the rest of the environment, there are passive systems used, specifically, in the rehabilitation building which will maintain better control of the space. Some of these include electric infrared heaters, operable walls and windows, stack ventilation over the hay storage and waste management areas, and Big Ass Fans in the arena. Both buildings have large flat roofs which will be used as both sod roof and for PV installation. The PV will be used to power as much of the buildings as possible and will provide a powerful combatant against the cost of running such a highly-powered hospital and rehabilitation center. The isolation facility for the hospital will be run on its own ventilation involving HEPA filters and other contagion controls systems. The ventilation for this portion of the building will be directed towards the open landscape, away from the main hospital building.

This heat pump maintains the open areas of the hospital. This includes the dirty corridor, the nursesâ&#x20AC;&#x2122; station, the exam areas, the mechanical spaces, and the conditioned horse stalls. This needs to maintain a moderate temperature level, comfortable for both humans and horses. This heat pump maintains the staff and student offices as well as the multipurpose room. These rooms need to be maintained at a temperature level normal for humans only. The majority of the zones on this level are concentrated here for higher control dependent on the occupant of each space. This heat pump maintains the surgery suites, locker rooms, prep areas, and necropsy zones. Each of these zones has a highly specific, time sensitive temperature that must be table for certain periods of time. They are also the highest ceilings in the building, needing extra power to regulate the space. This heat pump works with a conventional fan room for extra power. This heat pump maintains the two zones for isolation: one for horses and one for humans. These will be kept at different temperatures dependent on the client. This system works with a separate ventilation system with HEPA filters for contagious diseases. This heat pump maintains the human reception areas, business offices, client consultation, and conference room of the east building as well as the circulation for the student living above. It should be kept at a temperature suitable only for humans since horses are not permitted in this portion of the project.

This heat pump maintains the staff break area, the main storage, the owner education center and restrooms on the north side of the rehabilitation center. These areas will be kept at a temperature comfortable for humans since horses are not permitted in this area of the project. This heat pump maintains the rounds room, exam area, and wash bays. Because horses will be wet in this area it is extremely important to maintain a specific temperature.

Double Height Space

Operable Windows

Operable windows allow for a considerable amount of air flow and permit the expulsion of heat to the North and South

Double height spaces in the center of the buildings require the ductowrk to travel up to the ceiling through a shaft which is located in the storage area of the surgery suite and at the back side of the north bathrooms in the library & gallery space.

HVAC Ductwork

Ductwork is exposed throughout the buildings. Specific areas have dropped ceilings of slatted wood in different orientations for a smaller sense of scale within the massive areas of tall ceilings and wide halls. All clinical spaces (surgery, radiology, necropsy) have a suspended gypsum ceiling and an enclosed plenum space for ductowrk and electrical for ease of maintenance.

Indoor//Outdoor Space

Indoor//outdoor space allows for an intake of fresh air in the second level of the hospital as well as provides relief from the heat rising in winter and harnessing prevailing winds from the south in the summer

Hospital Section A | North_South

Interior //Exterior Dutch Door

By providing a dutch door in each stall, every conditioned horse stall has the option of bei=coming an indoor//outdoor space, providing excellent ventilation and exposure to nature that is vital for the improvement of the horses health. By making it a dutch door, it allows the staff to dictate the degree to which the horse can engage with the pasture and outside air.

Hospital Enlarged Section B | West_East

Indoor//Outdoor

The major concept of the rehabilitation center is creating indoor//outdoor communication which will help heal and adjust horses to the natural environment they are best suited to live in. These indoor//outdoor stalls have a dutchdoor and can give a high level of control over how much access horses have to pasture.

Passive Cooling

Big Ass Fans and high ceilings allow for there to be plenty of passive cooling strategies in the open air arenas, both soft and hard surface. The second floor viewing gallery also benefits from this.

Heaters

In order to have more outdoor spaces, the building is maintained during the winter using exposed, electric infrared heaters installed by attaching to the structure and dropping down to the ceiling plane level . These heaters will also be supplemented by movable partitions to block wind.

Stack Ventilation

By directing stack ventilation away from the prevailing winds we can direct the smells from waste and gasoline from the garage and waste storage area up and away from the main recreation areaas while still keeping them at a localized point between the two buildings.

Rehabilitation Section A | North_South

Operable Walls

Operable walls line the eastern face of the building on the southern wing. These walls will cut wind, or alow wind to pass through as well as provide shade and spatial definition within the building.

Breezeways

The orientation of the bulding provides halls which create gentle breezeways throughout the southern wing of the rehabilitation center. This passive cooling strategy can be used during summer.

Rehabilitation Section B | West_East

The lighting strategies of this project will create distinct qualities of light within different parts of the program to better differentiate the aspects of the project from each other, as well as celebrate the pastoral landscape of the site through its access to daylight. The upper floors of both the hospital and rehabilitation center have the most access to daylight. Since these spaces are both viewing galleries and library spaces, it is important to have daylight for both visibility and diffuse lighting for lower floors. Both of these spaces will also light up like glowing boxes in the landscape at night, celebrating the place with artificial light lifted above the ground, floating. Within the hospital, both natural daylight and artificial light have equal importance. It is necessary to have extreme control of lighting in the surgery suites and prep room for both accuracy and visibility. This light will be enhanced by the diffuse natural daylight from the viewing galleries above. The stalls will have access to daylight through the window openings that look out onto the landscape, providing fresh air and light to those that need it, and the possibility of closure for those that need extreme control of their environment. Skylights will provide daylight for specific areas in the hospital, specifically the large corridors through which the horses are led and are lined by offices. These skylights will provide light were it is difficult to reach inside of the building and will improve the experience of passage. Along the entry side of the hospital, glazing provides views to the constructed landscape as well as daylight for the nurses and exam room areas. This glazing also provides views and lighting for the offices along the north side of the building and the reception and conference room areas. The south walls of the hospital will be thick massing walls in order to help with heat gain and certain places of privacy. These walls will have large window punches in them for light and distinct views of landscape. The windows will be set back into the wall, creating deep voids in the massing which will provide much needed shadow at this orientation. Overhangs around the outside of the building will provide shade and places of rest on the exterior of the envelope. These places will encourage people, both clients and staff, to appreciate the landscape and provide spaces for rejuvenation and peaceful thought. Roof overhangs on the second level will provide space to enjoy the sod rooftop and views of the landscape. Overhangs on the ground floor will provide space to engage with that landscape in different ways. Some of these shaded areas will provide circulation and access to the building on the ground floor. These areas will use material patterns to project shadow onto surfaces, creating distinct speeds and spaces along exterior routes. The rehabilitation center has been designed to use natural light to its greatest advantage. Large openings between interior and exterior celebrate the access to the natural world and its inherent healing qualities. Operable walls will play on the same material patterns of the overhangs in the hospital. These patterns will create distinct experiences in different programmatic areas. Clerestory openings in both the arena and the free walk create distinct lighting conditions with western light. Since the roof of this building acts almost as a pavilion, covering the program within, it creates a shadowed interior with deep recesses that mimics the Big Barn on site. In cooler temperatures, electric infrared heaters will be used, creating a visibly warm glow within the space it is heating. Artificial light will be used specifically in the community education areas and the exam rooms, places where both visibility and accuracy are necessary to the programmatic requirements. At night, the indoor/outdoor spaces will dimly glow with the light of a front porch, distinct from the landscape, but still a part of it.

part viii Lighting and Daylighting Considerations

By using a flat roof and orienting the buildings in pertinent directions, the roof can be covered almost wholly with PV panels which will supplement the heat pump systems inside the buildings. The PV panels will cover the roof and be incorporated into the green roof tray system except where the roof is occupiable on both buildings and both levels.

Through strategicly placed glazed openings in the 24â&#x20AC;? structural concrete wall, southern light will reflect into the back hallway creating a warm and inviting envrionment for horses during radiology. The depth will also aid in deflecting direct sunlight and helo with harsh effects of direct southern exposure.
