Certificação da sustentabilidade de edifícios de escritórios corporativos no Brasil.

O crescimento industrial, comercial e de serviços traz para as sociedades mais evoluídas uma série de benefícios, como o desenvolvimento econômico e o crescimento populacional, aliados a maiores oportunidades de emprego e renda. Entretanto, pela falta de uma consciência mais apurada sobre os possíveis impactos negativos de ritmo acelerado de crescimento, acaba-se verificando uma série de problemas sociais e, sobretudo, ambientais. Em razão disso, nos últimos anos, constata-se a preocupação de alguns setores da sociedade na busca do desenvolvimento fundamentado em práticas mais sustentáveis. Isso não tem sido diferente no setor da construção civil. A preocupação com a sustentabilidade nos empreendimentos é tema e foco de diversos eventos, tanto no meio acadêmico, como no profissional e governamental. Particularmente, o segmento de mercado de EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS tem sido alvo de pressão para o uso de práticas mais sustentáveis em todo o seu ciclo de vida, desde sua concepção, projeto, implantação e operação até a sua revitalização. Para aferir a sustentabilidade dos EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS, muitas empresas do setor buscam certificações de origem estrangeira, que possuem certas limitações em sua aplicabilidade no Brasil, as quais são discutidas neste trabalho. Neste contexto, esta tese visa à construção da CERTIFICAÇÃO DA SUSTENTABILIDADE DE EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS no Brasil, que é oportuna e necessária para tratar das condições de contorno e de realidade nacional. Para isso, foram realizados: [i] levantamento do estado da arte deste tema; [ii] construção da MATRIZ DE ATRIBUTOS para a avaliação da sustentabilidade dos EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS; [iii] entrevistas com formadores de opinião deste segmento do mercado imobiliário; [iv] visitas em EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS relevantes para as arbitragens iniciais; [v] a construção dos procedimentos, regras e rotina, com testes de validação e calibragem do SISTEMA PARA CLASSIFICAÇÃO.

Expansão imobiliária na cidade de João Pessoa, no período de 2009-2013: um caso de formação de bolha?

The housing boom recorded in recent years in the city of João Pessoa contributed decisively to the increase in housing supply across the all territory. This advance, however, was accompanied by a significant increase in property prices, which in itself generates enormous expectations on the support of the same medium and long term. From this apparent frame heating the housing market of this Capital. This study empirically examined whether this enhancement configured a typical process of bubble formation between the years 2009 and 2013 in this part of Capital. The empirical price dynamics of the housing market , was based on the indicators of price, rent and cost developed by Bezerra et al. (2013). The results of these local indicators increase the degree of confidence in the hypothesis seen, whatever, that the movement of prices in the main districts of the city of João Pessoa is a real estate bubble

Investimentos internacionais e a valorização imobiliária dos municípios de Maxaranguape e Rio do Fogo

Since the middle of 1970´s the world has been undergoing significant transformations, comes in a new era of global capital accumulation, and starts the called productive restructuring. This restructuring is materialized spatially through the reconfiguration of territory, redefining its uses and providing a new spatial structure. With regard to native of Rio Grande do Norte territory, there is, from the 1980s, the emergence of new economic activities, among which stand out tourism, which become stimulated from government policies. In this context, has stood the east coast of the state, because its beaches have recognized scenic appeal and environmental quality. Therewith business opportunity, international investors ended up investing in this portion of Rio Grande do Norte´s territory, especially over the last decade. The expansion of this process, to the north coast, resulted in the emergence of intense property dynamics in the municipalities of Maxaranguape and Rio do Fogo. The low value of the property and buildings, compared to the European market and the availability of real property, were the main factors that explain the attraction of such investors, who are now seen as new business opportunities with high rates of profitability, in tropical areas, hitherto remote geographical location of the economic system. Therefore, the objective of the research is to analyze to what extent the International Investment promoted the appreciation of property in the municipalities of Maxaranguape and Rio do Fogo. The time frame covers the period among 2000- 2013. The methodology consisted of the following proceedings: surveys and analysis of data collected in the property registry office of the Maxaranguape and Rio do Fogo municipalities; interviews with public and private officials that were important for the analysis of spatial transformations and the recovery of the property that occurred in the municipalities studied; collection of secondary data from official bodies, such as IBGE, MTUR, SETUR, BNB etc. Analyzing the information and data that have been cataloged, it was concluded that this investments are reinforcing old leisure and tourism practices existing in the past in those territories and, shifted (creating new territorial arrangements) a significant part of the eastern coast zone areas of the state. Another consequence connected to this recent phenomenon refers to property’s increase in value that has occurred in this part of the state, episode which is directly connected to that event. Therefore, it is realize that the expansion and the incorporation of the capital territories reveal, in part, the strategies of the capitalist mode of production, which are evident in the search for better conditions of accumulation, expanding the alternative of use of the properties which occurs in selective way and uneven in the geographic space form. It is observed that the mechanisms that capital makes use to impose their practices can happen through the property’s increase in value market, meaning, thereby, that the reproduction of imbalances happens, often, through the marked property speculation with the fast increase in value of properties.

Esquina edifício: uma proposta arquitetônica para um edifício misto

Natal, como outras cidades metropolitanas brasileiras, sofreu nas últimas décadas uma forte transformação impulsionada pelo mercado imobiliário e pela indústria da construção civil. A produção de apartamentos em condomínios fechados vem crescendo e tornando cada vez mais comum, no cenário urbano, a presença de torres residenciais (com extensos muros e grades, fachadas cegas e guaritas) que favorecem o “desurbanismo”. Por outro lado, este tipo de empreendimento, o edifício multifamiliar, apresenta plantas baixas padronizadas as quais frequentemente são incoerentes com a diversidade de perfis dos usuários. A consequência disso são reformas e adequações nos apartamentos após a entrega da obra. Diante deste contexto, elaborei uma proposta arquitetônica, que é apresentada nesta dissertação, como alternativa a essa modalidade de produção que está se tornando dominante no Brasil e em outros países. Dois conceitos nortearam esta proposta: a) o conceito de urbanidade cujo objetivo no projeto arquitetônico é favorecer a percepção do outro (por copresença e/ou cociência) através da permeabilidade, acessos e passagens entre o edifício e o entorno. A maneira como os cheios (barreiras) se estruturam com os vazios foi trabalhada de modo que definissem propriedades espaciais cuja intenção é facilitar o encontro e a diversidade entre moradores e entre estes e os de fora, no entanto sem desconsiderar o problema da violência urbana e, consequentemente a importância da promoção de segurança para os usuários. b) o conceito de flexibilidade a fim de possibilitar ao consumidor final o desmembramento da unidade habitacional em duas e, em especial, a participação e ou escolha na concepção do arranjo interno e da definição dos acabamentos do seu apartamento. Tudo isto durante a construção do empreendimento e ao longo da sua vida útil, favorecendo assim o potencial de diversidade (grupos sociais), adaptabilidade a fases distintas da vida e durabilidade do edifício.

O olhar das instituições de previdência sobre a casa e a cidade: promoção, financiamento e avaliação de imóveis

The investments of Caixas and Institutos de Aposentadoria e Pensões (CAP and IAP) in homes of Natal, between the decades of 1930-60, helped to boost up the local real estate market in consolidation at the time. Inserted in the first national policy on social housing in the country, these operations have demanded the creation of a wide qualified organizational structure, which would be from the "Central Offices" of Rio de Janeiro to the decentralized units of the federal states. The professionals linked to the Local Agencies have developed, on this matter, from activities related to the design and construction of residential complexes, to the daily study of financing proposals in isolated units. As from these studies, the evaluation of shelters was essential to the effectiveness of the policy, resulting in the production of data on the market value of the properties by observing and issuing judgments upon the living quarters of different social groups. Given these considerations, the aim here is to contribute to the understanding on how to operate these real estate actions in the legitimization of boundaries about the urban space and dwellings available to workers in Natal. Therefore, the views of the city and constructions expressed by the evaluating engineers in their technical reports have been taken as the focus. Being the main primary sources of work, these reports are part of the edifices process of CAP/IAP regarding Natal, whose content is systematized in the database "Enterprises", the HCUrb Research Group. In addition, there were used local newspapers at the time and interviews with professionals as complementary sources. It was found that, in general, the evaluations have configured – in a more everyday dimension of bureaucratic routines - a vehicle, among others, circulating ideas about "home" within the social security institutions, being imbued with assumptions historically constructed about the "modern habitat". Filled in loco, the reports expose the clash between modernizing ideals in vogue and clear limitations in the city scenario at the time. Fragmented images of the town are given to read through the labels assigned to the evaluated sites – these being coated of certain "scientific" character - which both legitimated and contributed to the dynamics of appreciation/depreciation of the soil and to the socio-spatial differentiation. Contradictions were evident in the endorsement given by the technicians when financing of admittedly precarious homes for insured disadvantaged categories at the local level - such as industrial workers - while strict regulations were imposed to new construction, designed, above all, to better paid categories. By identifying raters engineers as urban agents, members of a technical-focused operating system for safety and efficiency in the real estate investments of those authorities corporatist, it is desired the usefulness of further studies on these characters, their training, professional activity and participation in the construction of discourses and practices of intervention about the city and its buildings, discussing individual and grouped interests that were left behind.

O uso de redes neuronais artificiais na estimação do preço das habitações na ilha do sal, em Cabo Verde

Esta dissertação tem como objetivo desenvolver um modelo de redes neuronais artificiais para aferir as caraterísticas das habitações que mais influenciam o preço na Ilha do Sal, em Cabo Verde. Foram consideradas caraterísticas como: área, número de quartos, existência de varandas, existência de terraços, número de casas de banho, localização do imóvel, número de andares e proximidade com instituições públicas. A amostra utilizada considerou 1092 habitações no período de 2009 a 2014. Para além da análise baseada no desenvolvimento do modelo de redes neuronais, efetuou-se a análise pela estimação do modelo dos preços hedónicos. Os resultados do modelo de redes neuronais artificiais permitiram verificar que o preço das habitações é fortemente influenciado pela área, e em seguida pela localização. A existência de caraterísticas, tais como a proximidade com a câmara municipal e finanças e existência de varandas, são as variáveis que menos influenciam o preço das habitações na Ilha do Sal. Os resultados da estimação com o modelo dos preços hedónicos indicam que o preço das habitações é fortemente influenciado por algumas variáveis representativas de características estruturais, localização e de vizinhança. Algumas dessas variáveis têm efeito estatisticamente significativo positivo no preço tais como, a localização do imóvel em Algodoeiro- Santa Maria, o número de quartos e a área. Outras variáveis têm efeito estatisticamente significativo negativo no preço, tais como a localização do imóvel no Bairro Novo e a proximidade com o hospital. Os resultados mostram que comparativamente com o modelo de preços hedónicos, o modelo de redes neuronais artificiais representa uma melhor alternativa para a previsão dos preços das habitações na Ilha do Sal, isto considerando a comparação dos erros estimados entre os modelos e as medidas de desempenho comumente utilizadas.

O Litoral e a metrópole dinâmica imobiliária, turismo e expansão urbana na região metropolitana de Natal-RN

The metropolitan regions of Northeast Brazil are being gradually included in a scenario of international investments, which are motivated by the restructuring of both touristic and real-estate sectors. The new capital, real-estate developers and space configurations that result from this process indicate the need for the creation and implementation of public tools which should, at least, allow the mitigation of the urban impacts and environmental losses resulting from this situation. The effects on landscape and on the socio-spatial configuration result from the intensification caused by the dynamism of the "real estate-tourism" sector. There is a regional integration as an expression of the urban expansion of the metropolitan area of Natal. This study investigates the uniqueness of the restructuring and territorial integration of coastal areas and the strategies of the circuit of capital accumulation formed by linking the real estate to tourism. It is intended to increase the understanding about the strategies of tourism, real estate and public policy agents involved in this territorial reconfiguration and in the fund-raising needed for the investments, to understand the existing social and environmental effects and their future trends and also to understand the forms of spatial production as results from the practices of approaching the land transformation and the tourism valorization of the landscape, in a synchronous manner, first in the Northeast region and, as a focal study, in the Metropolitan Area of Natal. Likewise, it is intended to apprehend the current processes of metropolization of the eastern coast of Rio Grande do Norte, in addition to indicate its physical-territorial transformation and the types of projects/developments promoted by the market in the recent period. Based upon analysis undertaken for the Metropolitan Region of Natal RN, this piece of work presents some considerations on possible legal instruments that can be adjusted to the municipalities which are experiencing the impact of this peculiar and recent phenomenon in the region, caused by the arrival of the real estate-touristic capital. It is also intended to point out basic proposals to the forms of public intervention, in a speculative way, starting from a Metropolitan Planning project within a medium and long term

Natal qual é a sua cara?: análise do perfil edilício da avenida Eng. Roberto Freire (Natal/RN) à luz da acessibilidade

This study focuses on the building ensemble of Avenida Roberto Freire, a main road in Natal, Brazil, as a material expression of the confluence of various factors among which the following may be emphasized: high level of accessibility due to urban spatial re-structuring and the growth of the real estate market, in view of the increasing number of consumers, who arrived in Natal within the last decades. The intense urban modification process that has been going on in Natal since at least the 1980s, has engendered the formation of long axial lines which express the expansion dynamics and some of the forces subjacent to it. Avenida Roberto Freire has been an iconic example of an urban thoroughfare where architecture becomes primarily a communication support that can be perceived by fast moving passers-by, what brings it close to the venturian concept of strip (Venturi at al, 1972). The building types that line the road not only respond to the dynamics in process but also contribute to intensify it, as they house a variety of uses which attract people and generate more movement. The dynamics is further strengthened by the action of the real estate business which benefits from the increase of highly accessible locations, and from the private and public investments and incentives to tourism that aim to insert this city into the globalized world. Although the intention of reconstituting part of the history of density increase on this avenue in a diachronical perspective was attempted within the limits of the available references and documentation, the central contribution of this study is to understand the relations between topological accessibility and the typological nature of the building ensemble. By observing the synchronic morphological frame resulting from the spatial configuration analysis pertinent to this avenue (cf. Hillier and Hanson,1984) and the inventory and classification of the building ensemble there existing, this study aims to understand how architecture responds to accessibility in view of the real estate pressure, boosted by a cosmopolitanizing process brought about by the continuous flow of foreign and Brazilian arrivals as visitors, temporary or permanent residents

Condomínios fechados: a produção habitacional contemporânea e a auto-exclusão dos ricos no espaço urbano de Natal RN (1995 2003)

The present work analyzes the fast evolution of gated communities in Natal-RN´s urban space. Characterized by the occupation of large areas, providing private security and utilities, this kind of real estate use arises a long list of questions and issues from society and scholars, due to privatization of urban space, bending of law constraints and the lack of an integrated planning of the cities where they are built. The reasons for its fast growth in Brazil s urban areas are analyzed, considering the impact on formal urban planning and municipal services and on the identification of urbanistic, architectural pattern and constraints, as well as legal, social and economic issues. This study is based on the detailed analysis of the first three units of gated communities built in the urban space in Natal, between 1995 and 2003, including their evolution throughout time and the specific social and economic reasons for its present widespread adoption in Brazilian real estate market and, particulary, in our city. The main objective of this piece of work is to answer the why s and how s these phenomena evolved, setting a basis for the definition of adequate public policies and regulation of this kind of urban land use

Entre o cartão-postal e a cidade real: um estudo sobre paisagem e produção imobiliária em Natal/RN

Recent studies concerning the landscape have investigated the most important activities that contribute for its modification and have tried to better understand the society through the marks left by its quotidian. It is understood that singular landscapes constitute the cultural patrimonies of the cities, once they are part of the daily life of the citizens and are present in their social representations. Some contemporary authors defend the preservation of the natural and urban landscape trying, specially, to keep its importance for the local population. Natal is a city where the ambient qualities are well defined and known by the beauty of the area where it is located. Situated just between a river and the sea, the city grew following its geographic characteristics. The Potengi River, the Atlantic Ocean and the vast dunes ecosystem represented natural limits to the urban expansion; at the same time they have favored the development of a landscape pattern marked by the dialectic between the natural elements and the human interventions. However, this relationship changed after the intensification of the high rising development process that took place since the 1960s. The urban legislation tried to preserve the features of the local landscape delimiting Areas for Controlling Building High , destined to protect the scenic value of some parts of the city. On the other hand, the civil construction sector has made constant pressure in sense to abolish or to modify this legal instrument, aiming profits that have increased, in the 1990s, because of the consumption and the qualification of the urban space for tourist activities. It is necessary the raising of new elements to stimulate the quarrel about the landscape preservation, the process of the urban space production and the best way for the legislation implementation. This work tries to raise elements about the subject at local level, in sense to use Natal City experience to contribute for the formulation of indicators to raise the question about the lack of measure for subjective values, for example the cultural and affective value of the landscape. The natural elements inserted in the urban profile, represent strong visual references and supply identity to the town; they are part of the collective imaginary and are detached in the social context of the city. Then, why the preservation of the landscape, that estimates the improvement in the quality of life, is not enough to justify the controlling building high already previewed as part of Natal City Legislation? These questions send us to the approach of the landscape, as a community patrimony, alerting that some of its significant esthetics attributes must be preserved as a legacy for the future generations
