Project: “ALGAE FARM�, by Maria Margariti
Ecology-Ecology The building is designed to house different uses as offices, student residences, laboratory etc. celebrating diversity. Moreover, the waste water is gathered to feed the algae farm that provides not only clean water (closing the water circle), but also energy, food and fertilizer for the hole block. And gathers the CO2 and converts it to O2. Also solar panels are placed in order to create energy and heat the water of the buildings.
EXERCISE 1 : FRACTAL ANALYSIS Ecology-Equity The building provides green spaces and vegetation for both occupants of the block and community and through the algae farm gathers the CO2 of the atmosphere and produces O2.
Equity-Ecology The buildings is constructed with ecological, low emitting CO2 materials, and follows the regulations of emergency exits and safety. Moreover, the atmosphere of the building is clean due to the gather of the CO2 and the O2 emission of the algae farm.
Equity-Equity The circulation and the communications of the building, as well as the careful design of the spaces that are open and extravert promote the sociability of the occupants and the creation of good relationships between them.
Ecology
All the products of the algae farm The water system of the building follows a closed loop as the waste water is supplied to the algae farm that filters it and gives it back clean for reuse. Moreover, all the products of the algae farm are used : the fertilizer is provided to the agriculture, and the biomass is converted to biodiesel.

Therefore, through the During the construction of the building it will and common ecologic materials building we can make profit by be certain that the construction employers making it that way accessible to a selling the excessive energy will be earning at least a living wage. reasonable range of user.

Project: “ALGAE FARM”, by Maria Margariti EXERCISE 3 : BUILDING DECONSTRUCTION
The structure of the building will consist a light steel structure that is easy to be constructed. The columns will be placed 2 to 2,5 meters towards the interior spaces of the building leaving the end of the beams free and overhanging. From the ends of those beams will be hanged the façade with the photobioreactors, creating a filter between the interior and the exterior space. For the flooring of the building will be used linoleum that consists an ecologic material. Also for the creation of the green roofs will be used specific vegetation mats.

Project: “ALGAE FARM”, by Maria Margariti EXERCISE 4 : LEED CERTIFICATION FOR SUSTAINABLE SITE
Credit 1 - Site selection:
The site is not located in any critical area, either in a land that consists habitat for protected species. In the contrary, it is situated in the urbangrid of Barcelona city.
Credit 2 – Development density and community connectivity:
The site has high development density of around 3m2 of built per m2, more than 60000sqft of built per acre (1,38m2 of built per m2). Also, it is near residential area, it offers pedestrian access to services and it is close to public transportation.
Credit 3 – Brownfield redevelopment:
In the site is going to be created a mixed use urban block (residential – commerce- library- offices –laboratory) and along with the algae farm will help at the regeneration of the formal industrial 22@ area.
Credit 4 –Alternative transportation:
The site is close to metro station and bus stops and the new building will include bicycle line and parking as well as underground parking. Moreover, as in the block will be placed many different uses, the need of people for circulation outside the block is minimized.

Credit 5 –Site development:
The project maximizes the open urban space with the new building being elevated and leaving the ground floor free for circulation. Furthermore, the roofs of the neighbor existing buildings will be transformed and used as green roofs and elevated plazas.
Credit 6 –Stormwater design:
The water system follows a closed loop with the gathering of the waste water and its’ supply in the algae farm that filtrates it and provides clean water ready to be reused.
Credit 7 – Minimization of the heat effect:
The introduction of vegetation in many places around the building, as well as the creation of green roofs will help in the decrease of the heat effect. Also, for the construction of the building will be chosen materials of high SRI (Solar Reflectance Index) values.
Credit 8 - Light pollution reduction: The lights of the building will be lighten only the hours that the spaces will be used and they will be placed properly. Also, during the night the only lights that will work will be the LED lights of the photobioreactors of the algae farm.
