There are several ways to attempt to model a building and its heat gains from external sources as well as internal ones in order to evaluate a proper operation, audit retrofit actions, and forecast energy consumption. Different techniques, varying from simple regression to models that are based on physical principles, can be used for simulation. A frequent hypothesis for all these models is that the input variables should be based on realistic data when they are available, otherwise the evaluation of energy consumption might be highly under or over estimated. In this paper, a comparison is made between a simple model based on artificial neural network (ANN) and a model that is based on physical principles (EnergyPlus) as an auditing and predicting tool in order to forecast building energy consumption. The Administration Building of the University of Sao Paulo is used as a case study. The building energy consumption profiles are collected as well as the campus meteorological data. Results show that both models are suitable for energy consumption forecast. Additionally, a parametric analysis is carried out for the considered building on EnergyPlus in order to evaluate the influence of several parameters such as the building profile occupation and weather data on such forecasting.

Esta dissertação trata do desenho de obra, tomado como um meio de aproximação aos processos de produção do projeto e da obra e às relações que se estabelecem entre eles. O desenho de obra é proposto como objeto de pesquisa, sobretudo, por representar mediação entre momentos e instâncias de concepção e de execução na produção do espaço, constituindo fruto do processo de projeto que orienta a construção em canteiro. A partir de aproximações teóricas ao desenho de obra, que o situam como instrumento técnico no modo de produção, foi estudado seu uso ao longo da história. Procurou-se entender os processos que engendraram a separação entre instâncias distintas de concepção e de execução na produção de arquitetura, determinados por uma crescente divisão do trabalho. Essas aproximações teóricas e históricas fundamentam as questões que guiaram a observação do trabalho e as conversas com os agentes de projeto e de obra em quatro situações concretas de canteiros de obras residenciais em São Paulo. As análises sobre essas situações buscam compreender as determinações recíprocas entre os processos de produção do projeto e da obra e suas implicações para o desenho de obra e para a produção de arquitetura.; The present dissertation discusses the building-work drawing...

À medida que os edifícios se tornam obsoletos, seja pelo não atendimento às condições normais de uso, seja pela necessidade de incorporar elementos que melhorem o desempenho e a eficiência deste edifício, a sua reabilitação se mostra não somente viável como necessária. Grande parte dos impactos gerados pelo setor da construção civil provém dos edifícios existentes, que não foram concebidos segundo os conceitos de sustentabilidade atualmente aplicados. Por isto, reabilitar um edifício para torná-lo mais sustentável contribui para a redução dos impactos gerados no meio ambiente. Realizar uma reabilitação para tornar um edifício mais sustentável é possível através da introdução de novas tecnologias aos sistemas deste edifício que se mostram obsoletos. A tomada de decisão sobre o conjunto de tecnologias construtivas a serem utilizadas na reabilitação de um edifício deve ser realizada de acordo com as potencialidades de intervenção e limitações do próprio edifício, sendo que a escolha da melhor alternativa depende de diversas variáveis, específicas para cada empreendimento. Desta forma, o objetivo deste trabalho é propor um processo para auxiliar a decisão dentre diferentes tecnologias de forma a tornar a reabilitação mais sustentável...

Após muitas décadas de mau uso das técnicas construtivas de terra, associando-as à miséria e habitações subumanas, há tentativas de resgatá-las e reintroduzi-las como opção construtiva digna. A terra, utilizada como material construtivo, possui muitas potencialidades, especialmente quando se trata do meio rural, onde se apresenta em quantidade e variedade abundante, possibilitando maior flexibilidade na técnica a ser utilizada. Além disso, as áreas rurais brasileiras, inclusive os assentamentos rurais de reforma agrária, têm um déficit de moradias proporcionalmente equivalente ao das áreas urbanas, porém não recebem uma atenção equivalente na forma de políticas públicas e investimentos. Os programas habitacionais federais, em sua maioria, são desenhados para a população e dinâmica das áreas urbanas e não contemplam particularidades do campo e do trabalhador rural. No Assentamento Rural Sepé Tiaraju, localizado no município de Serra Azul-SP, 77 famílias acessaram recursos provenientes de um programa habitacional federal e do INCRA para construção de suas casas. Dessas 77, um grupo de 10 famílias auto-intitulado de Grupo Alternativo, optou por construir suas casas utilizando materiais ditos mais sustentáveis...

Este trabalho tem como objetivo apresentar o projeto de um Prédio de Energia Líquida Zero (PELZ), ou seja, um prédio onde o balanço de energia é menor que ou igual a zero, em escala anual. Este projeto ilustra a possibilidade da construção de edificações eficientes, através de corretas alternativas. A ocupação terá como padrão um prédio de escritórios, dentro de um ambiente acadêmico. Para tanto, se utilizou dados climáticos e o software de simulação EnergyPlus. As estratégias para os sistemas da edificação utilizadas neste projeto: utilização de painéis fotovoltaicos, sensores fotoelétricos e dimerização para controle da iluminação artificial, prateleiras de luz para difundir e homogeneizar a iluminação natural, seleção de equipamentos eficientes, coleta de água das chuvas e uma torre evaporativa para realizar o arrefecimento dos ambientes. Com estas aplicações, realizaram-se simulações para alcançar os resultados visados. O balanço energético líquido, em escala anual, foi de -1516 kW.h, significando que, no sítio, foi consumido menos energia do que produzido pelos módulos fotovoltaicos. Além disto, teve-se a preocupação de manter conforto térmico e conforto lumínico para os ocupantes. A menor temperatura no interior da edificação...

Introdução: O macrossetor da construção de edificações causa um significativo impacto sobre o ambiente natural. Tal impacto é gerado em três momentos: produção, uso e descarte das edificações. Embora exista uma crescente consciência na indústria de edificações sobre a necessidade de redução desse impacto, os esforços atuais nesse sentido são limitados devido à incompatibilidade entre o paradigma atual, no qual estão baseadas as práticas da indústria, e os princípios de sustentabilidade a serem incorporados àquela prática. Para que a indústria possa avançar, tornando suas práticas ambientalmente mais sustentáveis, um novo paradigma deve ser formulado para servir de referencia à indústria de edificações. Objetivos: O objetivo principal desta tese é demonstrar as incompatibilidades entre o paradigma atual que inspira as práticas da indústria de edificações e os princípios de sustentabilidade. Os objetivos secundários são: definir com clareza os conceitos básicos da construção de edificações; formular uma estrutura conceitual que possa incorporar os conceitos básicos de maneira consistente e integrada; compreender o paradigma atual da construção, bem como os princípios que o regem; formular e propor princípios de sustentabilidade que possam ser utilizados no desenvolvimento de soluções tecnológicas para as edificações; elaborar as características essenciais de um novo paradigma...

The Old Municipal Chambers is a Category I heritage building situated in Worcester Street, Christchurch. It was designed by architect Samuel Hurst Seager in the Queen Anne Arts and Crafts Style and was opened in 1887. The two storey building is constructed in solid brick and incorporates several decorative features, and it is an important part of the cultural heritage fabric of Christchurch. Some securing works were undertaken in 1989 to improve its performance under seismic loads. This paper will outline damage during the earthquake on 4 September 2010, subsequent aftershocks and the 22 February 2011 earthquake which resulted in some localised zones of collapse. The structure of the building has been stabilised externally, to secure or allow retrieval of very significant heritage features. The high cost to repair the building makes the future of the building uncertain despite its very significant heritage value.In response to the building’s seismic vulnerability and possible retrofitting, finite element and simplified equivalent frame models were used for pushover analysis, enabling a complementary seismic evaluation from both approaches. The predictions identify the weak parts of the building and its expected failure modes...

The building regulations have a major role in controlling and limiting the energy consumption of the building sector. The Thermal Building Regulations of the European countries although had followed the EPBD Directive in what concerns the methodologies, differs on the re-quirements and recommendations on summer comfort and energy consumption for cooling, due to the particular conditions of each country. A review of the national building codes concerning envelope constructive solutions (opaque and transparent), thermal mass, ventilation rates, energy consumption methodology and correspondent values limits has been undertaken for the participating countries of the Keep-Cool II Project and, was extended to other countries, by consulting building codes, technical reports concerning energy use in buildings and by direct contacts with colleagues. The goal of this analysis consists on put in evidence the different strategies adopted and try to share and to supply information and experiences in so far as, the energy demand for cooling in European buildings is the energy use in the building sector with high increase rate among the other energy uses. In fact, cooling can be avoided or significantly reduced, with-out risking summer thermal comfort...

Disponível em: . Acesso em: 04 out. 2010.; In the last 7 years, a method has been developed to analyse building energy performance using computer simulation, in Brazil. The method combines analysis of building design plans and documentation, walk-through visits, electric and thermal measurements and theuse of an energy simulation tool (DOE-2.1E code). The method was used to model more than 15 o3ce buildings (more than 200 000 m2),located between 12:5◦ and 27:5◦ South latitude. The paper describes the basic methodology, with data for one building and presents additional results for other six cases

The strong main shock of the Great East Japan Earthquake (GEJE) of March 11, 2011, caused little damage to buildings. Buildings designed under the current building code and those with base isolation fared well. However, seismic design guidelines for nonstructural members had not been considered adequately, which resulted in problems such as the collapse of ceiling panels. Soil liquefaction occurred in reclaimed coastal area along Tokyo Bay and riverside areas. The key lessons of the GEJE are that seismic-resistant building design prevent collapse of buildings and protects human lives, that retrofitting vulnerable buildings is essential to reduce damage, that seismic isolation functioned well, and that nonstructural building components can cause serious damage. When applying these lessons to developing countries, local technical and socioeconomic conditions should be taken into account. This report gives findings; lessons; and recommendations for developing countries.

Building Surveying in Australia, through its professional Body the AIBS is in a state of flux. The demands being imposed on the AIBS by the new and developing specialist areas of building surveying, the consistent government interference and the conservative nature of its membership is making the organisation resistant to change and hampering its development. If the organisation is to survive it will need to lose its conservative shackles and be more proactive in embracing change. This paper uses a case study approach to develop the ingredients for success that the AIBS can use to improve its performance and relevance and lead to a sustainable profession.; George Zillante

CHDS State/Local; Since 9/11, the U.S. has developed policies to counter the terrorist threat. Integral to those policies is preparedness. Homeland Security Presidential Directive 8 states that preparedness will include, "capacity building prevention activities such as information gathering, detection, deterrence, and collaboration related to terrorist attacks." Despite the criticality of capacity building in relation to preparedness, the term is not defined. There has been no discussion on what capacity building means. The term is often equated to federal assistance or used interchangeably with capabilities and capability based planning. Capacity building strategies, however, are distinct and link into wider economic, political, and societal issues. Despite capacity building's criticality to preparedness and sustainment, various or ambiguous interpretations will translate to differences in strategic priorities. This thesis will examine the existing strategies to determine the linkage between capacity building, preparedness, sustainment, capability, capability based planning, and the envisioned end-state. It will also address sustainment issues and homeland security costs based on differing capacity building interpretations. The end product is a capacity building definition that captures the costs and variables with building and sustaining capabilities. This thesis will also demonstrate how capacity building measures serve as the foundational premise for a sound homeland security strategic plan.; Lieutenant Commander...

The Australian Building and Construction Commission (ABCC) was established by the former Howard government to regulate the building and construction sector. The establishment of the regulatory body followed damning reports by a Royal commission which alleged that building and construction workplaces were characterized by a widespread disregard for the law. An Interim Building Industry Taskforce was established subsequent to the release of the findings. The Royal commission's recommendations were then put before the federal parliament which led to the passage of the Building and Construction Industry Improvement Act 2005 (BCII Act 2005). The office of the Australian Building and Construction Commission first began operations in October 2005. The Howard government had hoped the BCII Act (2005) would vastly improve the workplace relations framework for building and construction operations and ensure that all building work was carried out in a fair, efficient and productive manner. The Howard government had long been an advocate of industrial reform in the building and construction sector. It believed that the crucial economic role played by the building and construction industry in Australia was being undermined and had been hindered by a perceived trade union dominance of the workplace. The government also alleged that inefficient workplace production was occurring as a result of direct interference by unions in the workplace. Therefore...

This evaluation assesses the relevance and effectiveness of Bank support for public sector capacity building in Africa, over the past 10 years. It draws on studies of Benin, Ethiopia, Ghana, Malawi, Mali, and Mozambique; aggregate assessments of country strategies and operations across the Bank's Africa Region; and, reviews of three corporate and Regional programs dedicated to capacity building-the World Bank Institute, the Institutional Development Fund, and the Bank-supported African Capacity Building Foundation. Main findings suggest recent changes in approach have made Bank support more relevant; most capacity support remains fragmented; sector-specific capacity building approaches need strengthening; tools and instruments could be more effectively and fully utilized; and, quality assurance is inadequate. These findings underscore the importance of approaching capacity building in Africa as a core objective, and ensuring that Bank capacity building support is country-owned, results oriented, and evidence-based. The evaluation recommends that: the Bank strengthen its knowledge base...

The climate changes issue is probable the top priority concern of the governments of the most countries of the world. Rigid and drastic measures have to be taken by all nations in order to reduce the noxious gases emission to the atmosphere. This ambitious goal can be achieved by ruling the energy production, by having a much more sustainable industry and adopting a much more sustainable way of living by all of us. The building industry has also to adapt to these circumstances to make its contribution to achieve the above goal. Focusing on traditional building techniques which require simple technology and use natural and local building materials and, eventually, to adapt them for the present required quality standards may be a step to solve this problem. Half of the world' population, 3 billion people approximately, on six continents, live or work in buildings constructed by earth based building materials. The fact that earth is natural, abundant and local result in an unexpressive amount of energy spending and noxious gases emission when it is used as a building material and, consequently, makes it undoubtedly much more ecological and economic when compared to the others building materials such as reinforced concrete or steel. In this context...

Improving the efficiency and performance of the UK residential sector is now necessary for meeting future energy and climate change targets. Building Performance Evaluation and Certification (BPEC) tools are vital for estimating and recommending cost effective improvements to building energy efficiency and lowering overall emissions. In the UK, building performance is estimated using the Standard Assessment Procedure (SAP) for new dwellings and Reduced SAP (RdSAP) for existing dwellings. Using a systems based approach we show there are many opportunities for improving the effectiveness of BPEC tools. In particular, if the building stock is going to meet future energy and climate change targets the system driving building energy efficiency will need to become more efficient. In order to achieve this goal, building performance standards across Europe are compared highlighting the most effective strategies where they are found. It is shown that the large variance between estimated and actual energy performance from dwellings in the UK may be preventing the adoption of bottom-up energy efficiency measures. We show that despite popular belief, SAP and RdSAP do not estimate building energy efficiency but instead attempt to estimate the cost-effective performance of a building and thus create perverse incentives that may lead to additional CO2 emissions. In this regard...

It is now widely accepted that the residential sector offers significant potential for carbon mitigation. This is true for both the overall magnitude of emissions reductions and the cost per tonne of CO2(eq) mitigated. However, both the scope and scale of potential carbon mitigation pathways remain controversial. The pace of decarbonisation is also openly debated. Examples of some of these contentions include: centralised versus decentralised energy supply; energy efficiency versus low carbon generation; demolition versus renovation of the existing building stock and behaviour change versus technological solutions. Incontrovertibly, any one of these seemingly apparent tensions is not mutually exclusive, and the ultimate decarbonisation pathway will likely consist of most if not all of these proposed solutions being implemented to some varying degree. Despite the significant potential for carbon mitigation in the built environment, deep cuts have not yet materialised. It is argued that this lack of progress stems from a poor understanding of the highly complex socio-economic, socio-dynamic and technical physical systems that underpin energy use in dwellings.Modelling this requires requires novel methods capable of capturing the complexities that arise from government policies...

There is a growing need for rapid and accurate damage assessment following natural disasters, terrorist attacks, and other crisis situations. The use of light detection and ranging (LiDAR) data to detect and quantify building damage following a natural disaster was investigated in this research. Using LiDAR data collected by the Rochester Institute of Technology (RIT) just days after the January 12, 2010 Haiti earthquake, a set of processes was developed for extracting buildings in urban environments and assessing structural damage. Building points were separated from the rest of the point cloud using a combination of point classification techniques involving height, intensity, and multiple return information, as well as thresholding and morphological filtering operations. Damage was detected by measuring the deviation between building roof points and dominant planes found using a normal vector and height variance approach. The devised algorithms were incorporated into a Matlab graphical user interface (GUI), which guided the workflow and allowed for user interaction. The semi-autonomous tool ingests a discrete-return LiDAR point cloud of a post-disaster scene, and outputs a building damage map highlighting damaged and collapsed buildings. The entire approach was demonstrated on a set of six validation sites...

Effective legal redress against unlawful building works or construction activities can be an elusive target. Given the desirability of legal certainty attached to administrative decisions in terms of which building plans are approved, should the practical implications of this principle trump the equally important principle of legality? This article examines the - at times - competing imperatives of certainty and legality in the context of several recent decisions of the Western Cape High Court that related to applications for interdictory relief for the cessation of allegedly unlawful building works. The practical difficulties for an applicant in these circumstances are particularly acute when the relief is sought pending the final determination of an application for judicial review of the impugned administrative decision to grant building plan approval. The article highlights the approach of the Western Cape High Court in three cases to invoking considerations of legality in circumstances where building works had reached an advanced stage and the respondent had effectively achieved what has been described as an "impregnable position". The principal difficulty for an applicant lies in the fact that where interdictory relief is sought against building works that have reached an advanced stage...
