Contribuição de uma edificação como reservatório de carbono: um estudo de caso do Escritório Verde da UTFPR

Abstract

Nowadays, the humanity presence on the planet Earth brings alarming statistics regarding the environmental impacts associated with its needs. This research aimed to conduct a survey in CO2 emissions of some materials that were considered in the Green Office UTFPR by analyzing the partial energy life cycle, as well as the amount of carbon stored in these materials in order to subtract CO2 emissions from these values. Obtained values were compared to two forest types. One configures the Araucaria forest and other, a Pinus taeda plantation. Six materials were analized: Plastic-wood used on the deck and also on the pergola; Wood framing structure formed by panels of Oriented Strand Board, Pinus taeda studs and “I” beams also in Pinus taeda, windows in Eucalyptus urograndis; and a staircase made of Erisma ucinatum wood. The data were adjusted to allow the equivalence of the real carbon stored in vegetation types area. The results showed that the Green Office can equate to 555.85 square meters when compared to the carbon stored in the Araucaria forest and 706.16 square meters when the object of comparison is the plantation of Pinus taeda. Difficulties such as the lack of data and lack of processes control that can give support to such datas were verified as being present. This research concluded that the real carbon stock can be admitted as sustainability criteria for decision taking in civil construction as the cares about the environment increase.
