Utilizing local materials for improving the energy demand in the single landed houses in Indonesia is very promising, since it also entails less cost during production and transportation. Many possible scenarios have been proposed towards this end such as improving building craftsmanship, using double walls with cavity, double walls with bamboo in between and introducing less transparent glass. The scenarios are tested in terms of the additional initial investment in terms of energy and cost and the benefits accrued for life cycle energy and cost. Energy and cost payback are computed to evaluate each scenario and a framework proposed for quick screening of building materials.

Self-cleaning properties have received significant attention for the importance of their potential. Coatings at Nano-scales offer possibilities of using materials for self-cleaning surfaces. Recent efforts have begun to focus on the kinds of materials including metals, semiconductors and polymers. Such materials can have enormous potential in only a few applications. Moreover, the production of these materials requires high costs with low photo activity. In this regard, TiO 2 and its derived materials have shown acceptable and effective suggestions for this application. Moreover, the mechanism of self-cleaning has been explained by the effect of hydrophilic and hydrophobic. Hydrophilic and hydrophobic can have many applications in different areas like water purification, microfluidics and photovoltaic. In this review, the application of self-cleaning in solar cells and environment as well as TiO 2 derived materials and their applications in water management have been briefly illustrated. In addition, it has been explained that a huge number of self-cleaning materials, applications and improvement in utilities have been essential. In short, we have conducted a comprehensive review of the new approach and to mention numerous materials with hydrophobic and hydrophilic properties would be promising for most environmental concerns. Bio-inspired surface respond in nature through hydrophobic (Cicada Wing, Butterfly Wing, Lotus Leaf, Rice Leaf) and hydrophilic (Fish Scale, Snail Shell, Shark Skin) properties was divided in 4 and 3 respectively. Anti reflective coatings with self-cleaning properties have drowned considerable attention for both their basic appearances and vast applied usages. Antireflective coatings with self-cleaning properties have been considered because of their fascinating features and vast diversity of empirical uses.

"Technology is more beholden to architectue".
In this short research paper, I will argue that architecture and techne are not mutually exclusive. Foremost, I will provide confirmation that the development of techne throughout the 19th century is more beholden to architecture, than that of the engineering realm

O artigo que se apresenta pretende identificar as capacidades expressivas dos eco materiais na arquitectura., pois o apelo que habitualmente surge para a sua utilização tem como base a muita e variada informação técnica que os acompanham. Dominantemente apelam ao seu uso com base valores quantitativos (a massa, a poupança energética, poupança de CO2, etc.).
Este estudo pretende identificar as qualidades expressivas dos eco materiais, contribuindo para fomentar a sua utilização com base nas suas qualidades expressivas.
Metodologicamente, procurou-se definir o que são eco materiais e enquadra-los em famílias para posterior sistematização. Posteriormente, e dentro de cada família, procurou-se identificar as qualidades expressivas que cada família de eco materiais contem. Em parte as qualidades expressivas dos eco materiais são semelhantes aos materiais tradicionais pois resultam de upgrades dos mesmo, existem contudo alguns eco materiais que tem qualidades expressivas específicas.
Quer disponham dessas qualidades únicas, ou tenham as qualidades expressivas dos materiais tradicionais, os eco materiais traduzem em si uma qualidade significante ás obras em que são utilizados, pois trazem para a obra a vontade de criar um mundo melhor para um homem mais feliz, e essa é a essência que move os arquitectos e faz avançar a arquitectura.

This paper investigates an approach to the use of fractals in architectural design. Two major aspects are discussed. First, the effect of the direction of the line segments on the generated fractal, as well as, the proportions between the generator and the initiator. Secondly, the meanings attached to the lines segments that constitute the fractal are based on some known architectural organization. The goal is to develop a basis for using fractals to suggest architectural forms.

Forty years after inaugurating their now eminently successful architectural practice, John and Patricia Patkau are “beginning again.” So they happily declare in their new book Material Operations. This unique survey features eleven experimental works, from their 2010-11 Skating Shelters for Winnipeg’s frozen Red River, to the nearly complete Temple of Light overlooking BC’s Kootenay Bay. Each work is presented more as...

A deeper understanding of the effectiveness of adopting devices mounting shape memory alloy (SMA) elements in applications targeted to the mitigation of vibrations is pursued via an experimental approach. During a seismic event, less than 1000 loading-unloading cycles of the alloy are required to mitigate the earthquake effects. However, the aging effects during the time of inactivity prior to the oscillations (several decades characterized by the yearly summer-winter temperature wave) should be considered in order to avoid and/or minimize them. In this paper, the results obtained by carrying out, in different laboratories, fatigue tests on SMA specimens are compared and discussed. Furthermore, the effects of seismic events on a steel structure, with and without SMA dampers, are numerically simulated using ANSYS. Under an earthquake excitation, the SMA devices halve the oscillation amplitudes and show re-centering properties. To confirm this result, an experimental campaign is conducted by actually installing the proposed devices on a physical model of the structure and by evaluating their performance under different excitations induced by an actuator.

dissertação de Mestrado que se apresenta pretende aprofundar sobre ascapacidades expressivas dos eco-materiais na arquitectura.O apelo que habitualmente surge para se utilizarem eco-materiais no projecto temcomo base a muita e variada informação técnica que os acompanham.Dominantemente apelam ao seu uso com base valores quantitativos (a massa, apoupança energética, poupança de CO2, etc).
Este estudo pretende valorizar as qualidades expressivas dos eco-materiais,contribuindo para a sua utilização.Para o efeito utilizamos os critérios adoptados por Peter Zumthor no livro “Atmosferas”.Escolhemos esta obra pois é obra influente na actual produção arquitectónica e fala devalores essencialmente substantivos.A identificação destes valores qualitativos em obras de referencia que reflectem uma consciência ecológica e utilizam eco-materiais, valorizando a sua significância e aumentando a sua premência arquitectónica, complementará os aspectos quantitativos que habitualmente suportam os apelos para sua divulgação.
