MAGNOLIA ELEMENTARY SCHOOL Location: Arlington, Virginia Team Project - 3 Members Advisor: Robin Puttock

A SCHOOL OF JUNCTIONS BETWEEN THE INDOORS AND OUTDOORS TO ENHANCE THE LEARNING AND THE COMMUNITY This program is meant to replace Claremont Immersion Elementary School with a new building (123,000 sf) to accommodate 700 students. Designed to serve grades pre-K through 5th in Arlington, Virginia, the new Magnolia Elementary School will become a celebrated junction for students and community members to enjoy year-round. The building form is created from two rectangular volumes. The primary form, a 475’ long four-story volume, serves both administration and students. Each classroom is an L shaped form with an outdoor teaching balcony. It creates allow diverse collaboration options for students such as work on a lab indoors and then testing it on the balcony. In these classrooms, students work in a comfortable environment with beautiful exposed cross-laminated timber, northern daylight, and views of the Magnolia Bog.

Captured Carbon in the Classroom The CO2 captured in the CLT used to build one classroom is 4.4 tons. This is equivalent to four and a half 40 year old trees

Mechanical Room Education Students can look in the window and see the heat pump used to cool and heat their classroom.

The Magnolia Elementary School is located above four rock layers. Each floor of the represents one of the layers and creates a junction between the Earth and built environment. This educational stair teaches kids about each layer and learn that the Magnolia Bog is located above the sedimentary sand layer.

Flexibility: Classrooms follow the same module, it is easy to change second-grade classrooms into pre-K by installing toilets. The L-shaped classrooms create a space with flexible indoor and outdoor uses. Learning: The outdoor solar classroom teaches students about energy generation through PVs and water heating through solar hot water panels. Carbon Emission Reduction Strategies: Embodied carbon was reduced by placing the building in the existing location of the old school, minimizing land disturbance and the building footprint with a 4 story building, and using CLT structure, and planting 65 additional trees on site. Resilience: The Gym is located adjacent to the loading dock, near the bathrooms and cafeteria in case of emergency. Energy generators are provided and located on the adjacent mechanical room to operate the gym in case of a power outage. Mechanical System: Centralized location of mechanical room. Ground source heat pumps are supplied by geothermal wells and are shared among the classrooms. DOAS is located on 3rd floor rather than roof to allow more real estate for the PV array. Water: Bathrooms are stacked directly above cisterns located in the basement. Harvested rainwater is used for flushing low-flow toilets and irrigating the garden. Sinks and showers throughout the school are also low flow to help water conservation.

Sirewall ® • • •

Weathered Steel Panels

BUZZARD’S POINT Location: Buzzard’s Point,- Washington, DC Team Project - 4 Members Advisor: Ana Romann-Andrino

PEDESTRIANS ON THE WATERFRONT Buzzards Point is located along the Navy Yard area currently hosting two major stadiums. This calls for a renovation and urbanization of the site to bring more people to live, work, and be entertained. The main concept of our design was to attract people to the waterfront. Buildings were located in the center core of the site leaving openness along the waterfront edge thus creating a sense of backyard for its inhabitants.

SOCIALLY DISTANCED PARKELT Location: Washington, DC Advisor: Georgeanne Matthews

FLUIDITY IN MOTION The parklet becomes a serenity space where people escape from their busy lives. The wood ribbon encourages a constant movement through the space for people to experience. It allows them to move freely from one entry point to the other while having the option to sit down and relax or appreciate the artwork displayed.

LIBRARY OF POETRY Location: H st, Washington, DC Advisor: Carlos Reimers

DESIGNING FOR THE FUTURE The growing development of the H st corridor calls for the creation of a civic building that enhances the residential life within and around the neighborhood. Located in a mixed use residential zone, the urban library serves as an iconic building that continues and allows the modernization of the H st corridor. The centrally organized library located at the corner of 7th and H st NE, responds to its context with the continuation of the commercial strip by locating a cafe in the lower front portion that can be accessed from both the street and the inside of the library. Thus activating the space and attracting people into the building.

FIRE STATION N.10 Location: Arlington, Virginia Team Project - 2 Members Advisor: Robin Puttock

A RELATIONSHIP TO A GREATER WHOLE. INTEGRATING WITH THE COMMUNITY AND NATURE. The concept of the fire station is to create a relationship with a greater whole while integrating with the community and nature. In the parti, you can see we are embracing this central core that extends vertically. The building is oriented EAST-WEST to maximize energy and daylighting through the building, and it also takes advantages of views into nature while also creating views to the inside courtyard as you see in our site plan. w Because of the many necessities the occupation of a fighter must have, as well as the amenities and facilities they need to have, we created a building that embraces the firefighters, through its commitment to mental health and wellness while also optimizing the use and function required by the profession.

In the main floor, it is the main entry vestibule on the north side, the office spaces looking out to the four mile run located along this Eastside, and the multipurpose and study rooms on the Southside. Located here is our apparatus bay that allows for four pull through bays, and lined up along this west side are located the support spaces. In the middle of the level, it is the decontamination area that acts as a barrier to stop the spread of contaminants from the apparatus bay into the main living and working spaces.
