Abstract: This paper is an exploratory study that aims to evaluate the prospects for the use of wood in residential construction in Brazil. For this purpose, a survey about the evolution of the stock of wooden houses was conducted. Social, environmental and economic indicators, which could interfere with the flow of Brazilian residential construction, were analyzed. The first results indicate that the stock of wooden houses has had a discrete growth (1.42%, from 1970 to 2009), but the percentage in the total number of houses has decreased (13.6%). Supply for housing demand has been provided by masonry. The population increase and the GDP demonstrated correlation with the building of houses and the changes in percentage between materials applied to it. Masonry is the construction technique preferred by the Brazilian. Most potential consumers (60.8%) declared that they could live in a wooden house. The aspects that would negatively influence the decision of living in a wooden house concerned market value, durability, fire and insect attack; and positively, was the material, construction process and patrimonial value. The image of a wooden house may be a greater problem than the material.

Abstract: The transport sector is considered one of the sectors that cause serious environmental impacts and, being strongly associated to development, it is important to choose more energy efficient transport modes. With the growing environmental problems sustainability becomes essential in the transport sector by reducing energy consumption and pollutant emissions in the atmosphere. Accordingly, through the case study of soybean transport from Sorriso, state of Mato Grosso, to Santos, state of Sao Paulo, this study aims to define which mode of transport, unimodal or multimodal, may provide greater efficiency in the use of energy from fossil source, in both direct and indirect ways. The method evaluates the energy consumption in the life cycle of transport vehicles, ie, consumption and supply of fuel and energy embedded in fabrication. The analysis verifies the efficiency of the multimodal transport.

Abstract: The paper aims to conduct a study of glass design in the decoration, emphasizing the work done by Dale Chihuly. The methodology applied in this article has the means to research the work of that artist as well as based on the knowledge acquired in lectures and reading books that address the subject hereof. One of the expected outcomes of this study is to traverse the course of the glass until it becomes a piece of art created by Chihuly.
