THE METABOLISM OF THE PROJECT
The metabolism of the building is mainly based on the wind, the solar energy and the water recycling as well as on the biomass production. The design of this project combines passive design strategies with active strategies and renewable energies. The buildingâ€™s form, sculpted in response to environmental analysis and focuses on the natural ventilation, sun shading, high thermal mass, courtyards and vegetation.

EXERSICE 1. FRACTAL ANALYSIS TO DEFINE PROJECT INTENTIONS Ecology-Ecology: The metabolism of the building is based on the wind, the solar energy and the water recycling as well as on the biomass production. Except from the wind cones that I analyzed above, another environmental design feature is the big structural roof canopy which provides natural shading and incorporates photovoltaic and solar panels to generate energy. Furthermore, the aerodynamic shape of the roof allows the air movement inside the block. The farming activity takes place on the roof. Furthermore, on the project are implemented water conservation strategies. The rain water is collected through water tanks suited on the roof, stored and used to irrigate the various shaded roof garden.
Ecology-Equity: The design of this project combines passive design strategies with active strategies and renewable energies. The buildingâ€™s form, sculpted in response to environmental analysis and focuses on the natural ventilation, sun shading, high thermal mass, courtyards and vegetation. The main architectural feature is a combination of eight wind cones-chimneys which provide natural ventilation and cooling and grow from the ground level to the top of the whole structure. These elements constitute the basic energy and circulation cores of the project and serve as outdoor assembly spaces. Equity-Ecology: Recycling materials and rapidly renewable materials will be used at all the faces of the life of the building. The materials should be sourced from locations not very far away from the building site. Flexible, modular, prefabricated materials and furniture will help later also the recycling process.
Equity-Equity: The building is developed giving attention to the cooperation of the different spaces according to the uses and the different scales that are required for each of them. This gives the opportunity to the user to feel familiar in all the areas. The spaces that will be mostly used from the public are at the lower levels and they are separated from the residential area in order not to be mixed. Also, free open green spaces are located in between the buildings providing a quality of air and a nice environment.
Ecology-Economy: The designing of the building takes advantage of all the natural resources; solar radiation, wind, rainwater conservation, waste compost. The energy production of the solar panels of the roof can be considered as the main economically issue of the project. Economy-Ecology: Use of renewable sources, food production, water recycling and waste compost.
Economy-Economy: The seven-story, 30,000 square meter structure will accommodate commercial, retail, cultural, industrial, educational and residential uses as well as green spaces. Spaces such us retail, offices, residential and underground parking can be sold. The gain from that could be used from the suppliers/government in order to introduce even more new technologies for the energy systems and high cost ecological materials.
Economy-Equity: The construction employees will earn a living wage at contemporary prefabricated housing units that can be easily stand and remove. They can live there during the construction process and when these structures should be removed, the empoyeessome can be temporarly host to already building housing. Equity-Economy: The basic principal of the design was to create a block that could be open to the public, offering various activities relating to the educational sector, commercial sector, ofiices etc. This allows all types of people to approach the block. The building will be mostly used from students and employers who study and work there and also constitute the residence of the block.

The diagrams represent the entire block and the different scale relations; between the block and the ecosystem and also the between the different elements that constitute the whole block. In the first diagram are combining the natural and technical cycle where are describing the relations between the natural sources that are used, the production and the processes with the people and the community. In the second diagram can be seen in which way the naturalsources are used and its relation with the several factors.

EXERSICE 4. LEED SUSTAINABLE SITES Prerequisite 1: Construction Activity Pollution Prevention Potential technologies and strategies should be taken on account during the design phase of the project in order to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airbome dust generation. The main objectives are to prevent loss of soil during construction by storm water runoff or wind erosion, to prevent sedimentation of storm ewers and also to prevent solution to the air dust. To achieve that in my project, I will keep the few existing vegetation of the block till the end of the construction and also I will use temporary fast growing vegetation to protect the top soil. Credit 1: Site Selection The site doesnâ€™t have relation with any critical area. Credit 2: Community Connectivity In order to achieve the community connectivity should be examined the surround area, the pedestrian accesses to the services and the existing facilities in Â˝ mile radius from the block. The main facilities are super markets and restaurants and the very nearest transportation is the bus and the tram where pedestrian accesses for the stations should be designed. Credit 3: Brownfield Development Is not applicable to my project. Credit 4: Alternative Transportation For the transportation inside the block will be used electrical cars and charging machines will be installed at the parking of the buildings.
Also, bikes and bicycle stations will be offered within the site. The site is connected with the public transportation as a metro station, a tram station and a bus station are very near to the area. Credit 5: Site Development The main goal of the project was to maximize the open spaces and have native and adapated vegetation, as well as green terraces and roofs. Credit 6: Storm Water Design The roof farming and the gardens will stabilize the sudden water flow and minimize the speed flow. The central courtyards on the ground level which constitute of vegetation will allow the infiltration of water to the subsoil. Also, water tanks on the roof will store the rain water. Credit 7: Minimization of Heat Effect The minimization of the heat effect will be achieved using materials with high reflectiveness, green roofs and pavements. Vegetation at all the levels of the building and shading strategies also will help; the east and west side of the block will be protected from the solar radiation with vertical panels. Credit 8: Light Pollution Reduction The light pollution has to do with the internal lighting as well as with the external. For the internal lighting will be used lights that prevent the trespass of interior to outside at night. Also, light sensors and adjusting the type of light used according to the demands.
EXERSICE 5. WATER FLOW ANALYSIS IN THE USE PHASE
On the project are implemented water conservation strategies. The rain water is collected through water tanks suited on the roof, stored and used to irrigate the various shaded roof garden. Furthermore, the stored water can be provided to showers, laudries and lavatories after its warming with the roof solar boilers and then the grey water will store to ground water tank. The already dirty water can be used for flushing toilets. The black warer will be moved to sewage treatment center and aftrer its treatment it can be used again.
