Studio_Verticalscapes.

Sports Village, Madrid

The studio project consisted in the

design of a thermodynamic entity of

mixed ude in a specific climatic

condition(in this case Madrid). The

entity was based on the optimization

of its energetic transfer in relation to

climate and to its programmatic

mixture according to the following

steps:

?Creation of a thermodynamic mixer

with a fixed residential program of

5000 sqm and the other programs

defined in order to achieve an

energetic balance near of or equal to

zero.

?Defining the spatial organization

according to climatic parameters and

natural energy sources.

?Using internal or external artificial

sources of energy and determining

transmission cycles as well as spatial

devices dedicated to distribution and

storage of energy.

?Determining basic aggregation

system keeping in mind internal

organization as energy optimization.

?Finally, forming an architectural

proposal in coherence with spatial,

structural, material and productive

terms.

Studio_Spectral Process.

Sports Complex, Barcelona

The spectral method of our

architecture is no longer to work with

the tectonic, but rather to decompose,

disintegrate, and crumble it into a

multitude of microscopic particles of

heat, vapor and light disunited from

their whole, atomized. The space is no

longer a visible, solid and tactile

macroscopic block, instead it expands

itself, diffracts, and opens to the

infinitely small and the invisible. One

of the key points of the contemporary

meteorological architecture comes

from the Impressionism painting of the

19th century. It is the notion of

dissociation, decomposition, analysis,

We proceed by decomposition,

dissociation of the “whole” in elements

and then re-compose it, but with a

certain number of components,

according to other hierarchies,

updated priorities, and new needs.

Instead of gestalt which opposes a

holistic view by stating that “the

whole is different and not reducible to

the sum of its parts”, we postulate

that the isolated parts are more

interesting than the whole

Seminar_Building Structure.

Alternative structure of the roof of-

Porto Alegre Market by Eladio Dieste(1972)

_(with Shuva Chowdhury)

The rapid and overwhelming evolution

experienced by building technologies

in the last decades as well as the

multiple findings and improvements in

construction materials have shifted

and complicated the traditional tasks

entrusted to the Architects.

This seminar provided sufficient

background to formulate specific,

valid and efficient proposals in every

field. the 2 stages of the seminar

were:

to basically learn geometrical

approach to framework performance.

and secondly, getting familiar with the

primary concepts of structural design,

such as structural efficiency, pre-

loading strategies and elementary

structural types.

the problem of modification of the

Porto Alegro Market!s roof was to

understand the technological

component of the architectonic

project and skillfully detect and

determine the most reasonable

solution - one that can end up being

more appropriate and efficient.

THE 3D TRUSS

Flow of forces

According to the geometry of the secondary structure, the horizontal connectors in the roof transfer the load of the roof members to the truss.

The 3-d truss, in turn help in transmitting these vertical loads respectively to the main thick beam which then transfers it load at its end supports.

Introduction

The roof is needed to cover the whole market of 280 m overall-length and 47 m width, with the consideration of allowing light inside. For the

planned architectural design, we have used structural steel which can lead to an efficient and economic solution.

Basic ideas

The main elements of our roof structure constitutes

· 20 steel beams running from one end to the other end along the

width at 14 metres centre-to centre.

· Supported at one end by 4 steel members, which form a trapezoidal

form.

· These supports are further strengthened by horizontal steel

members (sort of a bracing) which hold the trapezoid in position.

· The main beam then supports a 3-d truss of a maximum horizontal span of 7 meters at the centre and diminishes at the end points.

· The roof also has horizontal steel bracing or framing to make sure that the load of the roofing material is transferred to the 3-d truss

members and then to the main beam-to make the roof act effectively.

· The profile of the roof ends in a curve to form a wall, and replaces

the existing wall in the design.

· The curve profile of the wall is made up by the bracing which is

supported by the column, in place of the old wall.

Seminar_Large Structures.

High Rise of 70 floors.

(_with Olga Romanova)

The buildings with few stories and

short spans allow for a great variety

of different possibilities at the time

of designing their frameworks; as the

number of floors or the span length

grow, the solution for each specific

case needs to be much more accurate

and uni-vocal. So, in the case of high

rise buildings this is achieved by

increasing the stiffness of specific

s t r u c t u r e c o m p o n e n t s a n d

progressively moving them to the

perimeter as the number of levels

grows.

This seminar aimed to an approach to

these domains based on the

combination of analysis and induction,

which is integrated by a sequence that

wonders about what, how, why and

where. Specifically, the seminar

established the key concepts of the

problem to be solved, to follow

showing the different possible

solutions out of any context; from

that point on, it was needed to

research the connections between

each specific problem and each specific

solution; following, a series of Case

Studies that were investigated with

the purpose of identifying the nature

of the structure that the architect

and the engineer designed for each of

them.

This scheme was then applies to both

high rise and large span buildings.

Seminar_Digital Culture.

(_with Sally Habib, Omaya Malaeb, Kristina Ukhina)

Digital design methods can be

differentiated into parametric and

algorithmic design approaches. As

methods of computability they are

part of the spectra that marks an

extension of traditional non-digital

design methods. The architectural

utilization of these digital methods is

based on the description of shapes by

means of NURBS geometry. The

firstpart was to explore the

evolution of the architectural

paradigm from the analog to the

digital by means of case studies. In

add it ion , the NURBS-modeler

Rhinoceros was be introduced as

software environment for parametric

and algorithmic design.

The appearance of parametric tools

represents a shift in the traditional

way of thinking architecture. It

enables the interaction, in the design

process, between two scales, global

and local, and the application of

variation versus repetition. According

to that, the later part was focused in

the introduction of Grasshopper as

parametric design software tool and

the understanding of how to

incorporate variation and geometric

control into the design process by

designing a chirungito in the beach of

Barceloneta.

Workshop_Productive Land Program

Tordera!s Geothermal desalination plant and Brine Bath

(_with Anna Alivio, Bechara Malkoun)

The Productive Land Program (PLP) is

oriented to research on and think over

the productive and energetic

capacities of the non-urban land as its

way to become economically and

s o c i a l l y s u s t a i n a b l e w i t h i n

metropolitan areas. The current social

framework is determined by the

financial and political crisis, -i.e.

economic deflation, breakdown of

public protectionism, redefine the

concept of private engagement, and

the urge to find economies of

subsistence. As a response to the

current economic and political context,

we avoided design strategies that

take into account actions supported,

p r o m o t e d o r m a n a g e d b y

governmental policies. Instead, we will

focus on design strategies which can

engage the private sector to be

developed.To successfully fulfill the

course’s main goal, we worked only in

assigned places where the land still

keeps a potential for production.

Therefore, we skipped both highly

urbanized areas and rural areas, and

concentrated on the fringe of the

Barcelona’s Metropolitan Area. The

basic idea was to develop a strategy

that identifies the resources and

defines the design solutions to

produce self-sufficient interventions

on the proposed sites, making them

profitable guaranteeing to keep its

natural condition (non-urban).

Workshop_Registering Landscapes of Uncertainty

A trip on which the memory of each

team member and their places of origin

establishes analogous relations

between different moments.

A trip that serves as a platform for

interchange, materializing in a series

of registers that settle into a map of

diverse identities and a critical

conscience that allows us to recover

humanization as opposed to the single

course of globalization.

This workshop consists in recording

and producing cartographic material

to reveal other realities that underlie

the urban routine, based on the

experiences of a three-day journey

walking along the course of a river as

it moves towards the sea, plus four

days of reproducing the collected

material in the workshop.
