Variação de recursos financeiros com a aplicação do regulamento técnico da qualidade do nível de eficiência energética de edifícios comerciais, de serviços e públicos (RTQ-C) na fase de projeto de uma biblioteca padronizada de um instituto federal

Abstract

Plan the use of energetic resources in Brazil public works it is essential in environmental management, what improve the importance of the energy efficiency in buildings. In this subject, there is no knowledge if there is reduction in financial resources in final cost of a Public Library building when is use the National Ambiental Certification. The goal of these study is to demonstrate the variation of financial resources when is apply the Energy Efficiency Rating Technical Quality Regulations for Commercial, Service and Government Buildings (RTQ - C) at the project of the Public Library of Bento Gonçalves campus in Rio Grande do Sul Federal Institute. To analyze the level of energy efficiency of the envelope building, was used the prescriptive method by WebPrescritivo (2010 - an online tool). It was determined and quantified the materials necessary for alterations of envelope building to get Level “A” energy efficiency. It was compared two budgets: first, the use of altered inputs rather the originals; and second, it was made a spreadsheet with the total value of Level “A” building compared with performed. The results was: to get the Level “A” in energy efficiency at the envelope build, it is necessary to add thermal insulation between the bricks that make up the external wall masonry. At the roof it was used reflective blanket and two thermal insulation layers. At the budget spreadsheet, the first analysis showed and increase of 104,84% of the financial resources. In the second analysis, the increase was 11,39%. About the final position of the external walls and which consequences brings to the percentual value, was compared two values resulted at the work performed. The conclusion was that there is an increase to ramp up a Level “A” library at Bento Gonçalves campus; when the two variations of the external wall are 11,21% and 11,47%. By these analysis, at the point of economic variability, could been saw that can be done. It is important know that the legislation, regulations and technical standards are recent. However, in a country that is preparing for future, energy challenges has to use labeling, not only to public buildings. Also it is necessary review the code of workshops Municipalities that not contemplate energy efficiency and thermal confort.
