Drawing and use of auxiliary projection nets (the program STEGRAPH)

The development of an algorithm for the construction of auxiliary projection nets (conform, equivalent and orthographic), in the equatorial and polar versions, is presented. The algorithm for the drawing of the "IGAREA 220" counting net (ALYES & MENDES, 1972), is also presented. Those algorithms are the base of STEGRAPH program (vers. 2.0), for MS-DOS computers, which has other applications.

VO2 thin films and nanoparticles for energy-saving applications in architectural elements

Vanadium dioxide (VO2) is a promising material with large interest in construction industry and architecture, due to its thermochromic properties. This material may be used to create "smart" coatings that result in improvements in the buildings energy efficiency, by reducing heat exchanges and, consequently, the need for acclimatization. In this work, VO2 thin films and coatings were produced and tested in laboratory, to apply in architectural elements, such as glass, rooftop tiles and exterior paints. Thin films were produced by RF magnetron sputtering and VO2 nanoparticles were obtained through hydrothermal synthesis, aiming to create "smart" windows and tiles, respectively. These coatings have demonstrated the capability to modulate the transmittance of infrared radiation by around 20%. The VO2 nanoparticle coatings were successfully applied on ceramic tiles. The critical temperature was reduced to around 40ºC by tungsten doping. Ultimately, two identical house models were built, in order to test the VO2 coatings, in real atmospheric conditions during one of the hottest months of the year, in Portugal – August.

O início da 3.ª série da revista arquitectura em 1957 a influência das leituras de casabella‑continuità e architectural review

A revista Arquitectura foi criada em Portugal em 1927 e publicou‑se até 1939. Em 1948 foi comprada por um grupo de arquitectos denominado ICAT (Iniciativas Culturais Arte e Técnica) que, até 1957, a edita como um meio de divulgação da arquitectura moderna, sob a orientação decisiva de Francisco Keil do Amaral. O número 57/58, de Janeiro/Fevereiro de 1957, é o primeiro a ser editado por uma nova geração de arquitectos, que procurava exprimir as tendências de revisão do Movimento Moderno que começavam a dominar o debate internacional, e o número seguinte é o primeiro da 3.ª série. Na viragem dos anos 50 para os anos 60 as revistas Architectural Review e Casabella protagonizavam o debate arquitectónico na Europa. Neste artigo, a partir da leitura de alguns textos chave de Carlos Duarte e Nuno Portas publicados nos primeiros números da 3.ª série da revista portuguesa, é analisada a influência que tiveram as duas principais publicações internacionais sobre os editores de Arquitectura.

Beneath the surface of the heritage enterprise. Governmentality and cultural representation of rural architecture in Portugal

This article focuses on the construction of heritage in rural Portugal. Drawing on anthropological fieldwork in the village of Castelo Rodrigo, it analyses the extensive protection and exhibition of domestic architecture in the framework of a State-led local development programme. By bringing in the messiness of daily practices, the article goes beyond neat theoretical formulations in the study of heritage such as Foucault’s theory of “governmentality” and Kirshenblatt-Gimblett’s notion of “second life as heritage”. It argues that the “conduct of conduct” is actually nowhere near as effective as its theoretical formulation might have us believe, and the second life as heritage suffocates the first life of houses as social habitats for the village population.
