OS IMPACTOS DA ILUMINAÇÃO SOBRE A SAÚDE E O CONFORTO EM EDIFÍCIOS DE ESCRITÓRIOS / THE IMPACTS OF LIGHTING ON HEALTH AND COMFORT IN OFFICE BUILDINGS

The article discusses how lighting problems can affect users’ health and comfort in office buildings. Beginning with data from building architecture, office project, lighting project, ergonomic conditions and ambiental comfort assessment, it was possible to obtain a comprehensive overview of the physical environment that was integrated with users’ information about their health and comfort conditions.. At the end of the study, it was possible to conclude that lighting problems were frequently associated with various unpleasant symptoms, especially eye irritation, and with discomfort complaints caused by glare. We concluded that to achieve a better understanding of the lighting problems it was necessary to integrate all the information about physical environment with the users’ opinion on health and comfort conditions. On this last point, the application of questionnaires to the building users was essential to identify the negative impacts of lighting problems.

Indicadores de desempenho de energia em edifícios de escritório: Estudo comparativo através de uma revisão bibliográfica sistemática / Energy performance indicators in office buildings: A comparative study through a systematic literature review

In the civil construction sector, buildings are responsible for the highest energy consumption. Such evidence can be explained by the absence or inefficiency of energy management, often triggered by failures or the absence of consumption measurements, analyzes and correction of deviations, as well as the lack of use of alternative sources. In this context, this research sought to analyze and compare, through a systematic literature review, energy performance indicators in office buildings. The study also includes a brief exposition on energy consumption in Brazil and in the world, facilities management practices and Key Performance Indicators (KPIs), which are tools that assist the energy management process of buildings. Through a systematic literature review methodology, 48 journals were identified, of which 14 were selected and 4 studies selected that formed the basis of this research. The chosen journals presented real energy performance indicators for 4 office buildings in Europe (Germany, Denmark, Sweden and Austria) and 4 building simulations in Brazil (São Paulo / SP and Fortaleza / CE and Florianópolis / SC, twice) . The results identified that European buildings consume less energy per built area when compared to Brazilian buildings. However, this research does not allow general conclusions to be drawn, due to the limited number of cases. In addition, there are several factors that must be considered to assess the energy efficiency of a building, such as: local climate, envelope, thermal insulation, use of efficient equipment, use and type of operation of the buildings.

Distribution of Building Nonstructural Components in Height Subjected to Cost of Damage for Low-Rise Office Buildings

Distribution of Building Nonstructural Components in Height Subjected to Cost of Damage for Low-Rise Office Buildings

174 structural and nonstructural components in former earthquakes such as Nisqually, Seattle earthquake occurred on February 28, 2001 (Filiatrault et al., 2001) and the Kona, Hawaii earthquake at 2006 (Chock et al., 2006; Gupta and McDonald, 2008), economic losses from damage to nonstructural components constitute far exceeded losses from structural damage in most affected buildings presenting an average factor ranging in magnitude from 5.7 to 8.4 for the nonstructural to structural damage costs. Moreover, nonstructural damage can severely limit the functionality of critical facilities such as hospitals' facilities, as demonstrated in the Northridge earthquake 1994 (McGavin and Patrucco, 1994), El Salvador earthquake 2001 (Boroschek and Retamales, 2001) and Kona, Hawaii earthquake 2006 (Chock et al., 2006). In view of development and implementation of performance-based earthquake engineering, harmonization of performance levels between structural and nonstructural components becomes vital as both of them contribute in economic losses as a merit for performance evaluation. Even if the structural components of a building

State of the Art of Double Skin Facades in Europe

State of the Art of Double Skin Facades in Europe

In Sweden the interest among architects in applying the technique of double skin glass facades mainly in new construction of office buildings has increased during the last years. Such buildings have been built primarily in the Stockholm area e.g. Kista Science Tower, the ABB-house, the new police house, Glashusett and the Arlanda Terminal F, but also in the other Scandinavian countries. All in all there are about ten modern glazed office buildings with double skin facades in Sweden. The purpose of the double skin has in these cases been to reduce high indoor temperatures with protected efficient exterior solar shading during summer and reduce transmission losses during winter, and in some cases also to reduce noise from motor traffic. The double skin façade in Scandinavia has very seldom been used for ventilation of the building behind. Modern office buildings in Sweden have high energy savings potential and potential for indoor climate improvements. They may have a lower energy use for heating, but does on the other hand often have a higher use of electricity than older office buildings.

Rev. Bras. Econ. vol.62 número3

Here we introduce an idea that, to the best of our knowledge, has not yet been addressed in the literature, which is the fact that uncertainty may not affect different types of investment in the same way. For example, investment in industrial real estate is typically much less industry- and firm-specific than investment in machines. While the resale of used machinery may face thin markets with few potential buyers, there are numerous possibilities for the conversion of an industrial building, or even a white-collars office building, into other economic usage. Therefore, one should expect that buildings have smaller reversibility costs than machines. Intuitively, the implication would be that an increased uncertainty worsens investment in machinery much more than investment in buildings. In this paper the validity of this assertion is examined. To do so, I build a model a la Abel et al. (1996), in which reversibility and expandability costs play a key role. However, I split capital stock into buildings and machinery. The idea is to analyze how these two forms of investment react to changes in their resale

INFLUENCE OF NETWORK EFFECTS ON THE DIFFUSION OF INFORMATION SYSTEMS: THE CASE OF OPEN SOURCE João Carlos Vinagre Ferreira do Rosário

INFLUENCE OF NETWORK EFFECTS ON THE DIFFUSION OF INFORMATION SYSTEMS: THE CASE OF OPEN SOURCE João Carlos Vinagre Ferreira do Rosário

When questioned if innovation is easier to happen in Open Source Software or in Proprietary software, Sun see it happen in both worlds. As examples they considered that the later Internet Explorer (Proprietary Software) versions copies developments in Mozilla Firefox (Open Source) and vice-versa, xml documents exist in OpenOffice since 2000 and now is in Microsoft Office, etc. Usually Proprietary Software when achieve market domination has lower incentives to keep the degree of innovation because is more concerned with costs and profits. That happened with Windows and Internet Explorer. Microsoft for instance, halted new versions of Internet Explorer for a few years, with version 6, and had no intention to introducing a new version except when integrated with Windows Vista. They changed their minds with the success of Mozilla Firefox and introduced Internet Explorer 7 before the launch of Windows Vista. Windows also started to be developed in a bigger pace after competitive pressure from Linux. In both cases Open Source innovation were adapted or used by Microsoft. Even in early days of personal computers, Windows was a copy from Macintosh that was a copy from a concept never commercialized by Xerox.

While it would be desirable to vacate the entire building for the duration of construction, the cost of renting the space required would be prohibitive. Accordingly, arrangements are being made to rent approximately 20,000 sq. ft. (1,858 sq. meters) of office space as close as possible to the Headquarters Building to provide swing space for staff displaced during the period that construction is in progress on the floors they occupy.

HIGH PERFORMANCE GREEN BUILDINGS

HIGH PERFORMANCE GREEN BUILDINGS

Thus, equatorward-facing windows maximize the heat gain in winter while minimizing it in summer for mid-latitude sites. During transition seasons, an east-facing window can provide heat gain when it is most needed – to warm up a building after it has cooled during the night. However, a moveable shade will be required to prevent overheating. West-facing windows are more likely to cause to cause overheating. Any heat that is collected will be useful in commercial buildings (arriving as workers begin to leave) but will be more useful in residential buildings. The minimal useful heat gain and maximum summer heat gain through west-facing windows might imply that the window area on western façades should be kept very small, except that substantial energy savings are possible through daylighting. The keys are to choose windows that minimize heat loss and unwanted heat gain and to use adjustable external shading (Harvey, 2006).

Adjusting to Open-plan Office

Adjusting to Open-plan Office

work where noise is not really “tolerated”. Therefore, my suggestion is that project tables should be more isolated or even replaced for individual workstations. If project tables are more isolated it is easier to stimulate more interaction in this particular area. This can be achieved by introducing movable walls making a barrier between project tables and the rest of the office. The employees at DNB seem to take a great care not to disturb their colleagues and a more isolated project table may result in more interactions. The other solution is to replace the project tables for individual workstation. According with the interviews conducted by the research team employees are not satisfied with the project tables because they are only equipped with one screen per seat, they are not adjustable in height and working in teams in this tables without disturbing the other co-workers seems to be a challenge. Additionally, every time there is group work or specific task that request more interaction DNB staff books a meeting room immediately. Finally, project tables are only used in last case scenario when there are no available individual workstations for employees and there is no other option besides working in the project table.

Human Crowdsourcing Data for Indoor Location Applied to Ambient Assisted Living Scenarios

Human Crowdsourcing Data for Indoor Location Applied to Ambient Assisted Living Scenarios

some limitations still discourage the investment on their application worldwide. In Smart- SLAM [37], the way that the particle filter is developed to reconstruct the movement, only allows the system to build maps with the layout of the buildings’ main corridors, requir- ing a further process to explore unmapped areas. The solution presented by H. Luo et al. [38] will have problems if applied in large buildings, since every segmented signal is compared to each other, rising the processing costs. Contrarily, PiLoc [39] only works for large buildings due to the fact that the system only segments curves with more than 10 steps and straight line paths with more than 30 steps, a number too high for an elderly’s home, for example. Finally, UnLoc [40] needs at least one seeded landmark to trigger the system, which can be for example the entrance of a building, with a GPS coordinate. The system will start working only when a user passes by this landmark, a requisite that might not be feasible in buildings with multiple entrances, as a hospital.

O marketing interno e a qualidade do serviço prestado pelo back-office ao front-office como factor determinante da satisfação do cliente externo

O marketing interno e a qualidade do serviço prestado pelo back-office ao front-office como factor determinante da satisfação do cliente externo

O aumento da competitividade entre as instituições financeiras Moçambicanas tem levado as mesmas a dedicarem bastante atenção à qualidade dos serviços prestados ao cliente. Porém, a concentração da Administração, no delineamento de objectivos estratégicos e concretização de planos comerciais arrojados, deixa, muitas vezes, para segundo plano a qualidade que deve estar presente nos serviços prestados internamente, entre áreas, ou seja, na relação cliente- fornecedor interno. O presente trabalho discute uma disciplina emergente no contexto organizacional, o Marketing Interno e pretende-se com a adopção deste conceito, melhorar a qualidade do serviço prestado pelo Back-Office ao Front-Office da rede comercial prime do Millennium bim, considerando esta relação como sendo um factor determinante da satisfação do cliente externo. Para tal foram realizados dois questionários, um a 331 clientes com contas domiciliadas nos balcões prime da cidade de Maputo e outro aos 91 colaboradores destes balcões, tendo-se posteriormente analisado os dados obtidos. Apesar da literatura indicar que a satisfação dos clientes internos influencia positivamente a satisfação dos clientes externos, os resultados indicam que há uma relação inversa entre a satisfação dos clientes internos e a satisfação dos clientes externos.

Safety analysis of modern heritage masonry buildings: Box-buildings in Recife, Brazil

Safety analysis of modern heritage masonry buildings: Box-buildings in Recife, Brazil

typology, together with the poor control of the construction process, technically inadequate constructive solutions, poor quality soils and the presence of contaminated agents in soil and water. There is an urgent need to find a solution to this problem, given the precarious conditions of many of these buildings. It is noted that it is difficult to predict the failure in advance as the floors above ground do not present much damage at collapse. Indeed, most of the collapsed building fell without previous warning. As it was stated, the problem involves more than 250,000 people and there is still a lack of methodology to assess the safety, and to strengthen and repair these buildings. The results obtained give valuable hints for understanding the involved phenomena and for addressing possible structural strengthening, as the areas more sensitive to the structural problems have been identified.
