URBAN ECOPUNCTURE
They are the sustainable urban transformation strategies developed on particular nodes or ‘points’, in order to stimulate a larger network or ‘lines’causing the reactivation of a complete urban system or ‘surface’.
These small-scale urban interventions can transform the larger metropolitan context through ecological, social and economic strategies able to reactivate ecosystems.
What is Urban Ecopuncture?
I
STUDY AREA SCALE
It is fragmented into monofunctional enclaves. At this scale, the activation of an eco-network using a set of minimal interventions is proposed.
Community Nodes
The community centers and schools can serve as nodes to activate the green network.
Park Connectors
Existing and disconnected network of park connectors.
Public Open Space
Existing public open spaces inside the perimeter area.
Infrastructure Barrier Expressway and river block global and local movement, despite several access gates.
Current Infrastructure
Existing mobility infrastructure regarding roads and trains.
Urban Superzoned
Fragmented, superzoned and single-use planning results in longer travels,wasting energy.

CONCEPT PLAN
ECO NETWORK
The proposal aims to provide a feasible connection between the existing green spaces while introducing community functions and amenities to activate them. Treating the active green spaces as ‘nodes’ connected by a ‘linear network’ results in the creation of an ‘eco-network’ in place. The toolbox concept is proposed in order to integrate functions in said green spaces (nodes), such as: Community farming, Water Transit Oriented Development, SOHO, playground environments and art exhibit center. This eco-network allows people to access public amenities in and around the existing green spaces, making them community cores.

How is the proposal relevant today, and more importantly, for 2050?
Cities of the future, due to their size, are increasingly polycentric, and there is a need for self-sustenance within these centres. This includes the demand for an economically viable and comfortable lifestyle for all ages, especially the elderly. This proposal makes possible a symbiotic communal living, thus creating self-sustaining ‘urban villages’
The holistic integration of an ecological network into the site generates a new ‘module’of neighbourhood that can be incorporated into urban waterfront environments in the future. With degrees of hybridity in the vertical programme,the use of open spaces and the types of green spaces, the site offers a conducive Live-Work-Play context for users of all ages.

LIVING FILTER
Hybrid’carbon sink’urban model for the Barcelona Metropolitan Area in 2050.
Reducing carbon dioxide emissions is a multi-faceted problem, and requires a multi-faceted solution. This proposal aims to maximise biological CO2 absorption in Barcelona Metropolitan Area by 2050 through a network of microalgae production hubs, the pilot of which is the designed site (a nexus for production, jobs, research, education and living) thus, weaving together natural, productive and social ecosystems to create the perfect ‘climate era’ resilience model for Barcelona.

What is microalgae?
It is the “diverse group of microscopic organisms that inhabit in marine and freshwater habitats,able to perform photosynthesis”.
How can we use it?
Industrial-scale microalgae production in photobioreactors requires sunlight, CO2 and water to produce biomass
The value-added products of biomass generation have several useful applications for the chemical industry. Additionally, this microalgae ecosystem can also be used to treat wastewater
Average global radiation ≥ 4kwh/m2/day
Water source (fresh or Mediterranean’s) ≥ 520 m3

Power Plant
47% of Spain’s chemical production comes from Catalonia, where the Barcelona Metropolitan Region hosts production,work,contextual knowledge and infrastructure. This clustering creates an agglomeration economy, providing better access to goods and skilled workers which companies need. Within this established chemical production system, our proposal integrates a network of microalgae hubs-sites with production, education, research and development, and offices.

METROPOLITAN HUB “LIVE-WORK-INNOVATE”
Located in the municipalities of Sant Adria de Besos and Badalona, the site is a vision for the area where urban day-to-day functions, ecology and microalgae production co-exist in harmony. A large estuarine wetland with a soft shoreline shares the space with the Three Chimneys, a landmark readapted into the area’s cultural magnet. Production functions are integrated across the site, with complementary programs; this increases efficiency and economic opportunities.

MOBILITY
Being adjacent to Barcelona city, the study area is at the fringe of the various networksof transport. The means of transport include regional rail, metro transit, tram transit, bus transit, and cycling network. While a minority are in close proximity to the regional rail stations, the majority of the residents rely on proximity to bus stops. The proposal improves the mobility networks, mainly increasing the tram network and the bus system in the car-lite design site.
METABOLISM
Local routes for water distribution, goods distribution, waste collection and energy system on-site are integrated into the municipal systems. An Elevated-Goods-Mover System (EGMS) is proposed for the collection of biomass and the distribution of commercial goods.
PUBLIC SPACE NETWORK
The network of public space offers recreational amenities and facilities, thus lending a local,metropolitan significance to the proposal in addition to its regional vision.

A way to earn these credits is to create or preserve on-site parks and green spaces (C40 Cities, 2016). The hierarchy of public green spaces in this proposal is thus developed according to the potential of atmospheric carbon dioxide sequestration. envisions a metropolitan-scale “landmark” green urban space for the residents of Sant Adria de Besos, with a major green spine that connects the Badalona marina to Chimneys. The proposal also improves the permeability of the site, with significant spaces like the wetland being 100% permeable, to decrease surface-water runoff.

ZONING STRATEGY
The zoning plan indicates a strategy integrating production uses across the site, with educational uses and o ffice uses along major axes of the site. In linking these crucial functions together in a considered, resilient, and non-exploitative way, vitality and local value can be brought along the corridor that extends from the River Park to the Badalona Marina.
FACILITIES DISTRIBUTION
The proposal significantly increases residents’ accessibility to basic facilities, thus improving their standard of living. 33.8% of the total land parcel area is dedicated to facilities alone, which are consciously distributed in the design site. Notably, they are also distributed along the urban commercial spine leading up to the Three Chimneys and affronting the district park spaces near the residential quarter of the site.

CONCLUSION
The proposed wetland (counted as protected ecological area) increases the total area of systems significantly, barring which, the proportion of total systems to total zones is 56.5% to 43.5%.

MICROALGAE HUB “LIVE-WORK-INNOVATE”
The proposal, as a hybrid car-lite production hub in Sant Adria de Besos acts as a regional ‘carbon sink’ and a metropolitan growth catalyst accommodating residences, offices and facilities in a high-density compact urban model.
The real innovation of the design is rooted in its attitude toward the site’s positives: the landmark Three Chimneys and the existing fabric, while integrating environmentally and economically sustainable production uses within a layer of vibrant public spaces and green. To tackle the primary issue of the municipality of Sant Adria de Besos, an urban “listlessness” due to being adjacent to Barcelona city, one of the strategies, the development of a water canal - was for productive purposes as well as for public recreational canalfront spaces, thus serving as an urban magnet complimenting the landmark attention of the Three Chimneys.

COMMERCIAL SPINE TYPOLOGY
The typology fronts the urban commercial spine, framing a major gate into the site. It is a vertical mix of office, hotel, residential uses with retail in the ground floor. With the canal as the source, water is distributed for productive and domestic use within the site. An elevated goods mover system ensures the distribution of commercial goods and collection of biomass. Solar energy is tapped into for productive uses, and can supplement the grid for energy purposes.element, the canal, lends vitality to many recreational spaces and for efficient productive uses.
