Geração de valor em green buildings : um estudo sobre shopping centers no Brasil

Esta pesquisa investigou as razões pelas quais gestores da empresa Sonae Sierra Brasil decidem adotar prerrogativas socioambientais; especificamente, em projetos de edificações sustentáveis (Green Building). O estudo almejou contribuir para o entendimento de quando a adoção desta modalidade de projetos gera valor na sua cadeia na percepção de diversos executivos da empresa, concorrentes e um de seus principais stakeholders: operações do varejo (lojistas). Assim, foram realizadas entrevistas que forneceram subsídios para a observação das manifestações de valor normalmente percebidas, fatores contrastantes ou limitantes destes valores e, por fim, observar se os valores percebidos por gestores da empresa são compartilhados por estes gestores externos a ela. Os resultados apontaram, principalmente, para valores intangíveis, como criação de identidade empresarial, integração empresarial e transferência de conhecimento e sinalização ao mercado, para as quais não foi observada qualquer ressalva. Relevou também que manifestações de valor, normalmente tidas como relevantes motivadores na adoção destes projetos, como diferenciação, e benefício de imagem e marca são frequentemente destacadas, mas acompanhada de questionamentos. Os resultados da pesquisa contribuem para o entendimento da forma como as organizações percebem os valores de projetos socioambientais. Com isso, auxilia administradores de empresas a tomar decisões embasadas em experiências passadas, e gestores públicos na formulação de regulamentações que visem à redução do impacto ambiental de edificações.

A trava bancária na recuperação judicial e o seu impacto nas formas de financiamento da empresa: uma análise através da teoria do “common pool assets” de Thomas H. Jackson

O objeto de estudo do presente trabalho é a Trava Bancária, mecanismo jurídico previsto no art. 49, § 3º da Lei de Falências e Recuperação Judicial de Empresas - LRF, por meio do qual dívidas contraídas pelas empresas junto às instituições financeiras são garantidas pela alienação fiduciária dos seus recebíveis. Serão analisadas as peculiaridades desse tipo de garantia fiduciária e, em especial, a prerrogativa que os credores detentores desse tipo de garantia possuem dentro dos procedimento de recuperação judicial de empresas, de não precisarem submeter seus créditos aos procedimentos concursais. Será feita uma análise para demonstrar que a manutenção da trava bancária diminui o valor de going concern da empresa em recuperação, pois a criação de um tipo de credor que é blindado quanto aos efeitos da recuperação judicial impede que essa mantenha-se como um procedimento concursal coletivo e compulsório, requisitos que são essenciais para incentivar os credores da empresa a trabalharem de forma conjunta, mantendo o valor de going concern da empresa recuperanda, com o objetivo de recuperar a empresa e saldarem seus créditos. Tem-se como objetivo demonstrar que, a existência da trava bancária na recuperação judicial, pode afetar negativamente o acesso das empresas ao financiamento por equity. Isto porque, os acionistas das empresas são os últimos da fila de credores a receberem caso a empresa entre em recuperação judicial, e, portanto, acredita-se que, ao saberem que existe um mecanismo que poderá inviabilizar a recuperação judicial das empresas em crise, atrapalhando sua geração de valor de going concern, é possível que investidores desistam de investir em empresas financiadas por dívidas garantidas pela alienação fiduciária de seus recebíveis, passando a ser essa uma variável levada em consideração quando da realização dos procedimentos de valuation para compra de participação acionária em empresas. Os pressupostos teóricos que serão utilizados para embasar a premissa de que a trava bancária gera impacto negativo no valor de going concern das empreas em crise, dificultando seu processo de recuperação, serão extraídos e elaborados a partir da Teoria da Common Pool Assets do autor norte-americano, Thomas H. Jackson. A relevância deste trabalho decorre da importância que o procedimento de recuperação judicial apresenta para as empresas em crise e para os seus credores, bem como a importância que esse tipo de procedimento adquiriu no País. Com efeito, desde a entrada em vigor da LRF no ordenamento jurídico brasileiro em 2005, cerca de 4 mil companhias já pediram recuperação judicial. Além disso, o trabalho mostra-se relevante por abordar questão relativa às formas de financiamento das empresas, assunto que tem reflexo no Custo Brasil e impacto direto no desenvolvimento da economia brasileiro.

High performance green buildings

This work aims to study and analyze strategies and measures to improve energy performance in residential and service buildings, in order to minimize energy losses and energy consumption. Due to the high energy dependence of European Union (EU), including Portugal and Slovenia, and high percentage of energy consumption in the building sector, there was a need to adopt strategies at European level with ambitious goals. This came to force EU - Member States to take measures to achieve the proposed targets for energy consumption reduction. To this end, EU - Member States have adapted the laws to their needs and formed specialized agencies and qualified experts on energy certification, which somehow evaluate buildings according to their performance. In this study, the external characteristics of the building in order to meet its thermal needs and from there to survey the existing and possible constructive solutions to be used at the envelope will be examined, in order to increase comfort and reduce the need of use technical means of air conditioning. The possibility of passive heating and ventilation systems also will be discussed. These techniques are developed in parallel with the deployment and design of the building. In this manner, to reduce the energy consumption, various techniques and technologies exploit natural resources. Thus, appear the more sustainable and efficient buildings, so-called Green Buildings have been appeared. The study ends with the identification of measures used in several buildings, proving the economic return in the medium to long term, as well as the satisfaction of their users.

The correlation between thermal comfort in buildings and fashion products

This article is about thermal comfort in the wearable product. The research correlates fashion and architecture, in so far as it elects the brise soleil - an architectural element capable of regulating temperature and ventilation inside buildings - as a study referential, in trying to transpose and adapt its mechanisms to the wearable apparel.

PCM thermal insulation in buildings

This paper presents the results of a numerical and experimental study of phase change material (PCM) filled walls and roofs under real operational conditions to achieve passive thermal comfort. The numerical part of the study was based on a one-dimensional model for the phase change problem controlled by pure conduction. Real radiation data was used to determine the external face temperature. The numerical treatment was based upon using finite difference approximations and the ADI scheme. The results obtained were compared with field measurements. The experimental set-up consisted of a small room with movable roof and side wall. The roof was constructed in the traditional way but with the phase change material enclosed. Thermocouples were distributed across the cross section of the roof. Another roof, identical but without the PCM, was also used during comparative tests. The movable wall was also constructed as is done traditionally but with the PCM enclosed. Again, thermocouples were distributed across the wall thickness to enable measurement of the local temperatures. Another wall, identical but without the PCM, was also used during comparative tests. The PCM used in the numerical and experimental tests was composed of a mixture of two commercial grades of glycol in order to obtain the required fusion temperature range. Comparison between the simulation results and the experiments indicated good agreement. Field tests also indicated that the PCM used was adequate and that the concept was effective in maintaining the indoor temperature very close to the established comfort limits. Further economical analysis indicated that the concept could effectively help in reducing the electric energy consumption and improving the energy demand pattern. © 1997 by John Wiley & Sons, Ltd.

Semi-automatic modeling of buildings from digital surface models

Semi-automatic building detection and extraction is a topic of growing interest due to its potential application in such areas as cadastral information systems, cartographic revision, and GIS. One of the existing strategies for building extraction is to use a digital surface model (DSM) represented by a cloud of known points on a visible surface, and comprising features such as trees or buildings. Conventional surface modeling using stereo-matching techniques has its drawbacks, the most obvious being the effect of building height on perspective, shadows, and occlusions. The laser scanner, a recently developed technological tool, can collect accurate DSMs with high spatial frequency. This paper presents a methodology for semi-automatic modeling of buildings which combines a region-growing algorithm with line-detection methods applied over the DSM.

The nematode community in the Atlantic rainforest lizard Enyalius perditus Jackson, from south-eastern Brazil

Studies focusing on communities of helminths from Brazilian lizards are increasing, but there are many blanks in the knowledge of parasitic fauna of wild fauna. This lack of knowledge hampers understanding of ecological and parasitological aspects of involved species. Moreover, the majority of research has focused on parasitic fauna of lizards from families Tropiduridae and Scincidae. Only a few studies have looked at lizards from the family Leiosauridae, including some species of Enyalius. This study presents data on the gastrointestinal parasite fauna of Enyalius perditus and their relationships with ecological aspects of hosts in a disturbed Atlantic rainforest area in the state of Minas Gerais, south-eastern Brazil. Two nematode species, Oswaldocruzia burseyi [(Molineidae) and Strongyluris oscari (Heterakidae) were found. Nematode species showed an aggregated distribution in this host population, with O. burseyi being more aggregated than S. oscari. The present study extends the range of occurrence of O. burseyi to the Brazilian continental area. © 2011 Cambridge University Press.

Regulating Green Buildings

Green buildings are becoming the new fixation for the building industry because of the impact they have on the carbon footprint and the cost savings they offer for utility costs. Governments have begun to produce policies and regulations that implement and mandate green buildings due to these successes. However, the policies are having troubles increasing the popularity and quantities of green buildings. There is a need for a way to produce better policies and regulations that will increase both the amount of green buildings their popularity. A decision-making tool, such as a decision tree, should be created to help policymakers who do not have the backgrounds to produce well thought out regulations. By researching the green building industry and its current status, key points can be graphed out in a decision tool that will provide the needed education for policy makers to produce better green building regulations.

Equation of Motion Governing the Dynamics of Vertically Collapsing Buildings

The present paper aims at contributing to a discussion, opened by several authors, on the proper equation of motion that governs the vertical collapse of buildings. The most striking and tragic example is that of the World Trade Center Twin Towers, in New York City, about 10 years ago. This is a very complex problem and, besides dynamics, the analysis involves several areas of knowledge in mechanics, such as structural engineering, materials sciences, and thermodynamics, among others. Therefore, the goal of this work is far from claiming to deal with the problem in its completeness, leaving aside discussions about the modeling of the resistive load to collapse, for example. However, the following analysis, restricted to the study of motion, shows that the problem in question holds great similarity to the classic falling-chain problem, very much addressed in a number of different versions as the pioneering one, by von Buquoy or the one by Cayley. Following previous works, a simple single-degree-of-freedom model was readdressed and conceptually discussed. The form of Lagrange's equation, which leads to a proper equation of motion for the collapsing building, is a general and extended dissipative form, which is proper for systems with mass varying explicitly with position. The additional dissipative generalized force term, which was present in the extended form of the Lagrange equation, was shown to be derivable from a Rayleigh-like energy function.
