Interest in blurring the limits between the natural and the artificial has been a constant in Juan Herreros’ work as an academic and investigator and in the projects produced by his practice. He has been a member of the Initiative for More Sustainable Architecture and Urban Planning of the Madrid School and directed the Architecture and Nature module of the Master’s Degree Course on New Abilities for a New Architect of the School of Architecture of Alicante. He has participated in specialised congresses and in research workshops. He has signed widely disseminated books like and between 2008 and 2010 he has been involved in directing Tisspas: “Workshop for Social Innovation and Development of Sustainable Architectural Services and Products”, whose results have been published in the book under the same name by the editorial group Cendeac Publishing House, Murcia 2010.
Together with Iñaki Ábalos, they were one of the practices selected for the “Zaragoza Kyoto. Architectures for a Sustainable Planet” exhibition of the Zaragoza Expo 2008. Some of the projects built by that practice, such as the Salburúa Bioclimatic Towers in Vitoria, have been repeatedly published as model works, but it is the projects for the Urban Waste Treatment Plants of Madrid, (Manuel de la Dehesa Prize at the Spanish architecture biennial 2000 and COAM Prize 1999) pioneering in the re-use of the energy liberated from industrial processes to achieve total energetic autonomy are the projects that have combined construction rigor, energy treatment and organizational program with the greatest precision, to the point of being considered showcase buildings that are normally concealed and invisible and unveiled as environmental awareness infrastructures, especially for the schoolchildren that visit them on a daily basis.
HerrerosArquitectos has been involved in several competitions for the construction of model buildings in matters of sustainability, with the most important being the “Munch Area” engaged in building an exemplary environmental district and of a building, the Munch Museum, which comes constrained by the most stringent energy awareness guidelines; and the Congress Center ÁGORA-BOGOTÁ in which the total avoidance of any air-conditioning units has been achieved. To this end, estudio Herreros has teams among its habitual collaborators who are specialized in sustainable facilities, corrective measures or advanced energy management systems, and has collaborated with the best engineering firms in this field, such as Transsolar, Arup, Idom and Cener. Other built examples, such as the administrative center of the company HISPASAT with its double façade also functioning as an integrated sun shading device, the prototype of the ecological and auto sufficient dwelling unit GAROZA-10.1 or still under development, the residential complex in ANFA-Casablanca are the subject of frequent compilations on environmental architectures.
