BALTIMORE'S ECLECTIC PAST OF VARYING INDUSTRIES AND COMMERCE HAS SCULPTED IT'S PRESENT, CREATING A RICH AND DIVERSE CULTURE WHICH FOLLOWED AND ADJUSTED TO THESE TRENDS. YET THIS HISTORY OF RISING AND FALLING POPULATION LEVELS, HAS LEFT HOLES WITHIN THIS RICH FABRIC.. LIBRARY SQUARE SEEMS TO BE AT THE HEART OF A RIP WITHIN THE COMMUNITY, AS A BREAKING POINT FROM PATTERSON PARK'S TIGHTLY WOVEN GROUP; WHICH LEAVES AN INTERESTING OPPORTUNITY TO RE-FORM A LOST CONNECTIVITY THROUGH ARCHITECTURE.

The Project

Centro Verde proposes a complete transformation of an area of the East Village by creating an interconnected network of green spaces that weave the neighborhood into the downtown area and to greater San Diego.Seeking to create an enduring community Centro Verde introduces new methods of engaging people with culture and education, while keeping in mind the beautiful San Diego weather. Adaptive, interactive and connective, iPARC is the social heart of the neighborhood. This open space is knitted to the rest of the site through a series of green alleys and enhanced streetscapes, creating a walkable community and encouraging a vibrant lifestyle.

Centro Verde aims to become not only the cultural and educational hub of San Diego, but also a pioneer neighborhood incorporating sustainable building and living practices. Replacement of existing electrical grid of the area with Smart Grid, using solar power to fuel street lamps and Wi-Fi benches, taking advantage of micro climate conditions for passive cooling and encouraging non-automobile ways of transportation, are all ways that reduce the neighborhood residents’ carbon footprint and as well as energy costs.

Objectives

Public Space: interactive Public Park with adaptive spaces, development of walkable green spaces within blocks that also increases store front and allow for outdoor dining seating area.Active Community: Enhancement of streetscapes that allow for various means of transit, including safe bike and pedestrian paths; neighborhood bike share system with hubs at various key points including the park and trolley station.Education and Culture: iPARC as the vibrant core of the neighborhood; Wi-Fi Park, outdoor library, outdoor theatre and performance spaces; Gallery spacesConnectivity: Green spaces and walkable streets, integrated transportationSustainability: Solar powered street lamps, solar powered outlets, solar powered Wi-Fi benches, Passive stack effect, replacement of the existing electrical system in the neighborhood with Smart Grid.

Passive Ventilation: Stacking Effect

Cool Air Enters

Hot Air Exits

The “stack effect” results when air in the building warms,

becomes more buoyant than outside air, and rises to

escape out of openings high in the building.

between inside desired temp and outside temp.

View Corridors-Neighborhood access and connectionsStreetscapes on all streets will be improved in order to accommodate alternative means of transportation. However, major streets like Broadway, that have the view of water will become neighborhood access hubs by enhanced streetscapes that allow for all means of transportation- automobile, public transit, bike path,

pedestrian walkways- weaving together streets that allow for less.

The form of the buildings have been determined by the way micro-climate conditions of San Diego and the this part of the east village would allow for saving energy; Taking advantage of the direction of the wind to create passive stack effect for cooling the buildings, looking at sun patterns to maximize day light use yet allow for ample shading

Micro Climates- Building Forms

Orientation

Specificity

Phase 1: The Corridordevelopment establishes a dynamic core that will transform the neighborhood creating demand for residential units. During phase one, substantial residential units and retail, that support each other, will be developed around the park as well as on the blocks neighboring the trolley.The initial focus will be on rental units that can later be converted to for sale units, due to the current economic circumstances. This strategic move will make the neighborhood a destination and a desirable location that will create demand for more residential and retail space. During Phase one some of the light industrial spaces will be transformed into Gallery spaces and artist lofts, to create revenue from the properties and also create character and vibrancy for neighborhood.

Phase 2: The Parkdevelopment will start construction of some office space on the east blocks of the site by the highway, providing support for local businesses and educational institutions located on the north of east village. Some lower cost residential units catering to students will also be developed on the north blocks of the site. Development of a hotel including short term furnished rentals will respond to the needs of the businesses. Ample residential and retail catering to these offices as well as to others who seek to move into the neighborhood will also be developed.This strategy, not only takes market demand into account, but it will also increase the value of the land that is situated between the east and west side of the site, laying grounds for the third phase of the development

Phase 3: The Communitydevelopment will focus on development of residential units for sale, as well as the remaining eastern blocks of the site which will be developed into more office space. As the project reaches phase iii Central Verde has become an active cultural hub and a destination attracting both locals and visitors, and hence is created the demand for tourist accommodations. A second hotel to be developed in phase iii is strategically located so that it will target tourists as well as attendees of events at the convention center, who want to be in this vibrant and lively environment with sufficient dining and retail options.

Green Corridors/ Pedestrian and bike PaseosGreen alleys between buildings and around the neighborhood are developed with needs of bikers and pedestrians to encourage vibrant, car-free neighborhood living.

Geology/Fault lines- Social HeartTaking the fault lines as the voids between occupiable spaces, they have been developed as green spaces that only allow for pass through connecting the public spaces and iParc together.

Alex Is an Irish Art Collector, visiting San Diego on one of the country’s largest art fairs taking place in Centro Verde. Her flight

lands in LAX, she takes the Amtrak for $29.00 and arrives in San Diego in 2hrs 50 min and gets to her hotel with the Trolley. She

checks into her hotel and ready to check out the art galleries and studios of local artists located in Centro Verde. What she enjoys

most is the outdoor gallery spaces and being able to just walk around or sit at a café’s patio and enjoy the installations. In the

evenings she enjoys a scenic walk to meet with her local friends in the gas lamp district for dinner.

Jess is an architect living in Irvine and has to commute to work every day. Her office is in one of the transformed lofts

in Centro Verde. She leaves her car at the Amtrak station in Irvine, enjoys a relax 1 hr 40 minutes ride to San Diego for

only 19.00.In San Diego she catches the trolley to work. The total 2 hour commute is the same as her driving to work,

however, much cheaper than what she would pay for gas if driving and she doesn’t have to deal with the stress of the

traffic. For lunch she enjoys the side walk patios of the café’s around her office. A few nights a week after work she

meets up with friends for a drink in the gas lamp district or Centro Verde, goes for a gallery walk in the neighborhood or

enjoys a performance at iPARC before taking a safe and relaxing trip back home.
