WATER | ENERGY | DAYLIGHT | THERMAL COMFORT
DEMAND CONTROL VENTILATION
HVAC CHALLENGES
Occupancy levels can fluctuate wildly, such as between peak occupancy when building is in use as a storm shelter (100+ persons) to having low activity during school or work hours (1-5 persona). Many rooms such as the classroooms will lie unoccupied for a large percentage of the day.
INFILTRATION BASIN FOR STORMWATER MANAGEMENT
DCV is the use of sensors to reduce the building ventilation rate during low occupancy hours and to ramp up the ventilation rate during peak occupancy. This reduces the amount of air being actively conditioned, thus preventing unnecessary energy use.
ACTIVE CHILLED BEAMS
ENERGY RECOVERY VENTILATION
ACB require less fan energy than traditional all-air systems, while improving comfort though reduced noise. ACB use chilled water circulated through the building to cool hot air.
Before indoor air is exhausted, an ERV system transfers heat from the warm outdoor air to the stale cold indoor air, pre-cooling the new air and reducing energy costs.
HYDRONIC RADIANT FLOORING
INDIVIDUAL ENVIROMENTAL CONTROLS
Radiant flooring systems can be comfortable at temperatures 6-8 degrees lower than conventional heating (ASHRAE).
THERMAL COMFORT STRATEGIES
TARGETS FOR SDA LEED V4: “Each regularly occupied space achieves sDA300/50% value of at least 55%” Target Achieved: 95% of floor area achieves sDA300/50%, meaning these areas receive more than 300 lux more than 50% of occupied hours.
ANNUAL SOLAR EXPOSURE (ASE) Floor area overlit more than 250 occupied hours annually WATER MANAGEMENT Floor area without excessive annual sunlight exposure.
Small scale systems, such as ductless mini splits allow dormant areas to be lightly conditioned when unoccupied while allowing individuals to control their thermal comfort in the space.
TARGETS FOR ASE
WELL Building Standard: “Annual sunlight exposure (ASE1000,250) is achieved for no more than 10% of regularly occupied space.” Target Achieved: Only 4.4% of floor area experiences overlighting with 1000 lux for more than 250 occupied hours annually.

GREENWAY PARK SYSTEM MASTERPLAN FOR MEMPHIS, TN Fall 2022 - Prof. Peter Summerlin, Graduate Studio III
SITUATION
The Epping Way portion of the Wolf River Greenway sits along central north Memphis. In its current condition, the site has few indicators of ownership that would decrease its perception as unregulated property. As a result of its currently isolated nature, the perception of safety is critical to public adoption. While the site is abundant in natural resources, the educational experiences of the site are limited to those facilitated by a tour guide. The current ecological exhibits are uninviting without a guide proclaiming their benefits. This proposal addresses these issues by creating a sense of adventure and identity for the site, re-imagining the ecological experiences, and supplementing the existing programming with new diverse opportunities. 14

TRANSITION FROM URBAN TO WILD
CANE BRAKE PLAZA
This is the moment visitors enter the northern edge of the park. The plaza is punctured by mounds of native cane, introducing visitors to a species that once dominated the Mississippi River tributaries but now exists in rare patches. The cane and paving form a figure ground relationship to create a transition from the urban to the wild: The paving is broken by cane patches until the relationship and proportion shifts to where the cane brake is dominant with meandering swarths of paving. The walls change from controlling the cane to being scattered into the cane. The plaza connects to the wetland weirs and to play zones to the south. 18

CAMPUS DESIGN
FOR MSU COLLEGE OF AGRICULTURE AND LIFE SCIENCES
Fall 2020 - Prof. Cory Gallo, Graduate Studio I
SITUATION The College of Agriculture and Life Sciences at MSU is growing, consistently outpacing the rate of new building development. The current growth patterns of MSU are suburban, defined by car-centric streets lined with low-rise buildings setback with large lawns and interspersed parking. CALS is also adjacent to the historic quarter of campus, where buildings are organized around a great vacant central lawn. This central green model was started in the early 19th century and was propagated across the country. The goals for this studio were to propose a third alternate model of development for the future of the College of Agriculture and Life Sciences.

AGENDA The campus district master plan focuses on pedestrians, density, shade and functional green spaces as an alternative to current car-centric land use patterns of campus. Four Patterns for Growth 1 - Build denser, taller building clusters around functional or recreational green spaces, creating smaller identifiable nodes across the district. The intent is to create multiple smaller distinct places instead of one large lawn to which all else is secondary. One such node for CALS could be adding a student farm to the existing greenhouses in the center of campus. Perspective looking north towards new pedestrian “forest” corridor
2 - Link these nodes into a web of densely forested and shaded pedestrian corridors. East-west traffic is addressed through a loop encircling the existing core of CALS with new building clusters forming the loop’s perimeter. Pedestrian boulevards handle north-south traffic. One such corridor is a pedestrian “forest”, where a boulevard is densely planted as shown in perspective above. 3 - Green spaces and pathways can serve double duty as a stormwater management network.

4 - De-prioritize car traffic by converting existing streets to be “naked” shared streets where pedestrians move freely and car traffic is subservient..

LIVING ROOM DESIGN|BUILD
FOR GALLOWAY ELEMENTARY IN JACKSON, MS
Fall 2019 to Fall 2020 - Profs. Cory Gallo, Hans Herrmann, Suzanne Powney
SITUATION The “Living Room” at Galloway Elementary School is an outdoor learning space designed for teachers across academic subjects to pull learning and classroom activities outside. The garden features learning structures such as chalkboards, storage and a workbench to facilitate curricular activities alongside garden activities. The intents of the living room is to provide a flexible space for gathering and outdoor learning. This garden is the first of three school gardens produced by a collaboration between MSU’s Dept. of Landscape Architecture, School of Architecture, and Dept of Graphic Design.
22
CONTEXT
The garden was commissioned by the Fertile Ground Project, a city-wide arts imitative. Galloway Elementary is located within the extensive food deserts of Jackson, MS. The garden is intended to be a playful, artful space for children to get excited about nutrition. Since Galloway, MSU has worked on three other school gardens, such as the Partnership school depicted to the left. Drone imagery from Fertile Ground JXN, other images by the author.
THE TEAM
The Department of Landscape Architecture at MSU developed a modular system of sub-irrigated planters and hoops using off the shelf agricultural parts. This system has been replicated and adapted
so far to three additional school learning gardens in Mississippi. The School of Architecture produced the classroom structures and 3D printed concrete stems and benches. The Department of
Graphic Design created colorful ground paintings for activity areas and walkways, as well as educational surface graphics covering each planter. 23
DRAWING FROM PARAMETRIC DESIGN PLACE TOOLKIT CASE STUDIES FOR DIGITALLY IN CONTEXTUALISM FABRICATED CONCRETE 2020-2022 - Advisor 2022-2023 Prof. Abbey : Prof. Franovich Hans Herrmann (Research Mentor)
SITUATION Emerging robotic construction technologies could create new possibilities for landscape architecture, particularly digitally fabricated concrete (DFC). This research imagines a potential application for DFC not yet exhibited: to create landscape structures that respond to their terrain. Digitally fabricated concrete is defined by new processes and parameters based on mechanical limitations and the properties of concrete that hardens in minutes instead of days. The toolkit helps communicate the “design space” of DFC to describe the feasible geometries for fabrication and identify the limiting process factors. The research proposes an adaptive and didactic design environment that allows 24
a designer to explore their ideas and see the implications of the fabrication system. This research resulted in a toolkit of modular scripts for DFC, demonstrated by retaining walls that adapt their geometry to their context and their varying structural loads.

In the above example, the soil volume is used to expand and shrink the wall proportions. The soil volume is also used as data for adding random variations to the wall form to add visual interest. The structural evaluation modules describe resultant forces and risks such as crushing and overtuning. The printability analysis checks the design for issues specific to 3D concrete printing during design, providing continous feedback. 25

DESIGN TOOLS AND SIMULATIONS
Significant progress has been made in the fields of materials science and robotics to create systems that print concrete at resolutions as small as a water drop as well as mobile robots that print large surfaces in minutes. These technical accomplishments indicate that implementation 26
cropped site with existing walls separated
challenges by designers and contractors are the critical limiting factor for DFC. Likewise, existing research has demonstrated the feasibility of robotic construction with digital terrain excavation and digital printing of concrete in-situ. This research aims to provide a toolkit to alleviate designer difficulties as well as speculate on the potential applications of robotic construction to landscape architecture.
First, a comprehensive review of systems and machine parameters was undertaken to describe processes for designing for the machine and choosing the machine for design intent. Second, the scenarios of a terrain response wall were developed to investigate how DFC might facilitate more individualized site-specific designs and perhaps even reduce material consumption.
PROJECT CONCEPT
Wall responds to soil volume actively retained
This became the basis for a series of Grasshopper modules for generating adaptive retaining walls and modules for fabrication feasibility and structural analysis. A local amphitheater was used to simulate the potentials of DFC by replacing the traditionally constructed walls with various freeform iterations feasible with DFC technologies.

The walls are created with a series of cross-sections matched to a particular soil volume fragment. This soil load is multiplied against designer chosen ratios to determine the wall proportions. This sets the basic wall form against which the designer can add random variations. The magnitude of these variations is also set as a ratio of the soil loads, where larger volumes of retained earth can have larger bulges in the wall form. The frequency of cross-sections, the size of the soil fragment each wall responds to can be enlarged or reduced, creating larger or finer geometries in the wall surface.
