The project was born from insistent calls from the neighboring populations and the workers, who workers who use the ESA campus the ESA campus.
A socio-ecological study was carried out immediately, in which the biomass density of trees in the biomass density in the trees of the reserve of the middle course of the Guadarrama in Guadarrama's middle course in kilograms per m3. The average annual precipitation for the last five years was analyzed, ranging from 700 l/m2 to 900 l/m2.
700 l/m2 and 900l/m2. And approximate percentages of carbon emissions are estimated.
According to industrial activities, 35 %, according to transportation, 25 %, agriculture and livestock necessary for its habitability, 20 %, residential and commercial, 15 %, and deforestation, 15 % and commercial, 15 %, and deforestation and changes in land and land use, 5 %.

The question arises how many trucks are involved in the construction of a metal-framed building and how much is the one of reinforced concrete. From this comparison is born the reflection of the great difference between on-site difference between on-site construction and its emissions, and more centralized construction with the need for centralized construction with the need for transportation and its emissions.

For a steel-framed building during the entire construction process an average of 10-20 trucks with all their routes, and for a reinforced concrete building about 10-20 trucks with all their routes, and for a reinforced concrete building about 10-20 trucks with all their routes for a reinforced concrete building about 30-40 trucks with all their routes their routes.

The metal buildings, C and M, are disassembled and classified according to M, to be sorted according to their capacity for reuse. Envelope, structure, and interior finish. The envelope will be changed of quartering, the structure will be exerted, heat tempering, and the interior will be used to make new parts, completely modifying its shape completely modifying its shape.


The project is developed by strips, there is a humid strip that separates the separates the winter zone, summer zone, which have different façade treatments against different facade treatments for sunlight and heat use. And between built areas, a flexible and growing strip that consists of natural textile pergolas. The different constructions have between 2 and 3 floors. And depending on the climatic conditions of each zone, the roofs are organized to favor the thermodynamic effectiveness of the spaces.

The roof system is also organized so that it can be inhabited by nesting birds. The typology also takes advantage of the slab width of 0.7 meters. The typology also takes advantage of the 0.7-meter slab width, since some trusses from building C are reused, in order to make the rest or meeting that the resting or meeting spaces are unhung between these dates, taking advantage of those 0.7 meters these dates, taking advantage of that 0.7 m of floor slab. In the winter to take advantage of the warmth of the nesting birds, some entrances to these slabs were some entrances to these slabs are created from the outside, together with the drinking troughs for birds.
