Procedimento para homologação de sistemas ecoeficientes para obtenção de créditos de carbono

This paper deals with the homologation process for obtaining carbon credits through the Clean Development Mechanism (CDM), that regulates the greenhouse gases reductions under the rules of the Kyoto Protocol. The CDM evaluates projects through a project cycle, which begins with the preparation of the Project Design Document (PDD) until the project certification to receive Certified Emission Reductions (CERs), popularly known as carbon credits. This study analyzed the implementation of the system Burner Recorder System for Low Flows of Biogas (QRBBV), developed by Marcelino Junior & Godoy (2009), in an eco-friendly wastewater treatment mini-plant (miniEETERA), built at the site of UNESP - Guaratinguetá SP. The QRBBV system is low cost and high reliability, developed to burn the methane generated at sites of low and variable production of biogas, which is not economically justified their energy recovery. Currently, almost all wastewater generated at the site of the campus is being treated by miniEETERA and, as a result, the biogas originated by this activity is being released into the atmosphere. Therefore, the project activity aims to capture and burn the biogas generated by miniEETERA, reducing the negative effects caused by the methane emissions into the atmosphere and, thus, claim to receive carbon credits. This work aimed to demonstrate the project applicability under CDM through the study and preparation of the PDD, as well as an analysis of the entire project cycle required for homologation. The result of the work obtained an estimate of only 20 CERs per year and proved to be economically unviable for approval through the CDM, since the spending with the approval process would not be compensated with the sale of CERs, mainly due the low carbon price in the world market. From an environmental standpoint, the project is perfectly... (Complete abstract click electronic access below)

Construção Enxuta e a utilização dos seus conceitos por construtoras paulistas certificadas segundo o PBQP-H e o QUALIHAB

The civil construction sector has been stimulated to industrialize itself by the adoption of Lean Construction practices in its constructive process. Given this fact, this research verify and identify Lean Tools and the level of application of these Tools in construction companies in the State of São Paulo, in order to be able to notice which Lean Concepts generate the highest benefits to these companies. The research method used was a survey applied only between construction companies that have some type of quality certificate. From the results, a data analysis was made in order to note the constructor's situation in relation to Lean Construction and, based on this analysis, verify the impact of the Lean Principles on the competitiveness of these companies and on the business performance. This way, it was possible to note a high level of application the Lean Tools by the responding companies. It also became clear, by means of this work: the strong influence of the concepts of Flow, of Continuous Improvement and of methods of prevention and resolutions of problems on the overall companies performance

EDiferentes tipologias de edificação e o ser sustentável mediante o LEED e o CBCS

The principles and dimensions of sustainability concept is increasingly gaining ground within the building industry. Over the past decades, its applicability within the different environments and for different buildings typologies have been study to attend better the present populations and future generations. It is within this scenario that international certifications started to appear. The most famous and developed one being LEED certification system. In Brazil, as a support to the certification and also sustainability practices and conducts, was founded the Brazilian Council for Sustainable Construction (CBCS). The council and the certifications have the objective to disseminate and generate awareness to reduce energy and water consumption, aiming for life quality. Many constructions around de country have already the international certification, which also boost the rise of national certifications with specific criteria for the national context. However, such certificates are mainly destiny for medium and high standard buildings, often as a commercial advantage to explain the high costs. The purpose of this work is to be able to define what is being sustainable in the construction industry, taking for basis, LEED and CBCS. In addition, since there is a significant increase in the production of Housing Social Interest, the other angles will be to analyze how to apply the practices and sustainable technologies for low-cost projects with the objective to balance the three dimensions of sustainability: environmental, social and economics.
