It's devised in this work the starting project for the implementation of a residential condominium, focused in the use of technics and technologies to attain sustainability, also stretching to the pilot project for the model house. It's highlighted the methods for exploitation and reuse of water, energy conservation and reduction of environmental impacts. The proposal is to demonstrate the possibility of the use of simple, but effective, ecology technics to make an environmentally sustainable and economically viable project. The main motivators for this work is the growing hydric crisis faced by São Paulo state and the unpaired importance of the sustainability concept as the fundamental term to surmount the challenge of supplying the needs of the current generation without jeopardizing the future of the next generations

Gás natural no panorama brasileiro e um estudo de caso no setor automotivo

The intended purpose of this paper is to present the main aspects of natural gas applied to the public transportation as well as the environmental, economical and technical impacts in this sector. Also it is given specific information to be considered when comparing natural gas to other fuels, specially the diesel. At this point is presented the types of internal combustion engines (Otto and Diesel cycle) and which type is used in each vehicle. Moreover, it is presented the main standards pollutant emission (Euro, US and Proconve) with a brief explanation of the tests made in order to approve the engines. This paper is focused on heavy duty vehicles. Also in this paper is exposed the economic impact due to the natural gas use in the public transportation fleet. In addition is presented a real case (of Berlin) and an estimative to a Brazilian city, presenting the potential of natural gas as vehicular fuel in Brazil, as well as financial and environmental aspects of the substitution

Certificações ambientais para construções civis

Over the recent human history within the last centuries the environmental degradation has been accumulating and growing rampantly causing effects today easily perceived by all. Because of this, today we can say that there is almost a consensus among the world population's concern with the environment in order to seek to minimize these effects immediately in addition to not aggravate the situation for future generations. Thus today it is common to find a wide range of products with this ideal of sustainable commitment in the various commercial areas. The construction industry has a responsibility to be a major cause of these impacts to the environment, so it is also one of the main vectors able to mitigate the degradation of the environment. In order to encourage, oversee and promote the sustainable attitudes within the construction area emerged environmental certifications. In this work it's exposed some of the major certifications for civilian buildings, highlighting the Selo Azul da Caixa that appears as a good choice focused on the Brazilian reality
