An important social burden using architecture as a generator of communities in “empty spain.” what is the km0 architecture?

In the era of technological development we also find architectural trends that aim to keep traditional construction methods and the use of local materials alive. As its name indicates, km0 architecture uses construction materials available in the environment . Materials that can be purchased locally, that do not require much industrial transformation to be used and that, at th WhatsApp Number List e end of their life, can degrade in the same environment. In the case of edra, the study works perfectly with the km0 philosophy. Since its foundation, it has sought a way to create different architecture using advanced materials and offering a range of natural materials linked to the customs of the territory: wood, adobe, stone, thermal insulation such as sheep's wool and straw,... In edra's own words: “in each project we aim to give continuity to the link with the environment . ” km0 materials are like this, ideal for achieving that link. An architecture committed to the development of rural areas it was social architecture edra architecture is highly committed to the repopulation of rural areas.

One of edra's social principles is to bring architecture of high constructive value, energy efficient and comfortable to the people . The office is convinced that quality buildings also have a place in rural areas. We refer more specifically to fusing current knowledge in sustainability with the implementation of vernacular materials and traditional techniques. Through its work, edra carries out important social work in the north of spain: it promotes the development of depopulated regions through architecture, which is closely linked to the work of reactivating communities in the aragonese and catalan pre-pyrenees. Featured projects most of the studio's built projects are located in towns near the pyrenees. The office is dedicated to carrying out “tailored” projects, both new construction and rehabilitation, mainly for the tourism-hotel and residential sectors. The style that marks his works is timeless and with construction material finishes seen in interiors but worked in detail , which gives it a refined rustic air.

This pre-existing 19th century building was completely rehabilitated, resulting in a sustainable and healthy tourist complex with a spa.

The project is pioneering for the use of earth as the main material , also in the interior surfaces. Its large windows with views to the south provide solar gains in winter. The heating system has a biomass boiler. Tapial house edra tapial photo: xavier d'arquer. Winner of the international terra award 2016 , we could describe the tapial house as the vernacular home of the 19th century: 80% of the materials used come from within a 150km radius. Furthermore, the house is an ideal example of passive solar architecture : thermal inertia and hygrothermal control thanks to the rammed earth walls. Free solar collection through large windows facing south. Sun protection. Thanks to the passive design and km0 materials such as earth with the rammed earth technique, environmental impacts and co 2 emissions were reduced by more than 50% compared to a more conventional architecture. The tapial house is also sustainable: it has a built-in rainwater collection and recovery system and is heated with a biomass boiler. House “stone, wood, wool, south” it was stone wood photo: edra arquitectura km0. The rehabilitation of this private home located in the pyrenees of huesca represents the paradigm of an architecture that reflects advanced knowledge in calculating carbon footprint and bioclimatic through a pure km0 material language: the main materials are stone (facade cladding), wood (window and interior profiles) and sheep wool thermal insulation.
