    Efficient daylighting approach by means of light-shelve device adequate for habitat program in Aarhus City2014In: International Journal of Smart Grid and Clean Energy, ISSN 2315-4462, Vol. 3, no 4, p. 441-453Article in journal (Refereed)
    Abstract [en]

    The concepts of light shelves consist of windows that have face towards the sun, which receive a vast quantity of energy that could be used for healthy day lighting. This paper debates a main assessment, investigates the optimization of daylight requirement by means of light shelves system. An experimental test was carried out assessing the measurements and lighting simulations of a model of a building in order to elucidate the characteristics of indoor lighting. Light shelf is an architectural element that permits daylight to enter deep into a building. It constitutes an optimal solution for an incorrect building orientation and less sunny days. The essential objective of this study is to highlight the vital role of light shelves in residential buildings in northern Europa where the requirement is to improve the daylight in the interior functional spaces. The main objects of this paper are to investigate the effect of daylight in the interior functional spaces using light shelves, the effect of natural light diffusion in interior space in the period of low daylight season, and glare effect in this field. This paper investigates a procedure for analysing the daylight performance using software habitat function

    Abstract [en]

    No Architectural concept is complete without green areas. The vital mission of biophilic architecture is to revised conceptualization of architecture in response to a myriad of contemporary concerns about the effects of human activity. Our earth is warming more rapidly than it has in the past according to the research of scientists. The green building of biophilic architecture combines the interests of sustainability, environmental consciousness, green areas of the large nature, and organic approaches to evolve design solutions from these requirements and from the characteristics of the site, its neighborhood context, and the local microclimate and topography. The biophilic concept provides us with the opportunity to reach extremely low levels of energy consumption by employing high quality, cost-efficient measures to general architectural components - such measures are in turn off advantage to the ecology and economy sector. Our essential task of this research is to make of the green covering a human strategy in urban and architectural manner and to be a human culture with helping of local governments; we can acquire the competent legislation, which protect our life and environment.

    Abstract [en]

    After the terrible consequence of the Iraq –Iran war and recently USA attack over Iraq the urban green covering disappeared from large areas of the city, beside the extension of the building over the green areas. The negative effects of this phenomenon over human’s thermal comfort become more perceptive. Today we can observe clearly the negative effect of urban heat island in the center of Basra city, precisely in physical frameworks of the city; we can observe a typical phenomenon with a large negative effect for the period of summer heating that is a natural thermodynamic phenomenon. In the surfaces of physical framework, in the core of day between 12-15 pm, the sun is shining perpendicular above the earth surfaces (framework physic). Consequently the temperature on the earth surfaces increases surprisingly up to 60 ºC. Therefore there occurs a difference of temperature between the earth surfaces and cosmos space which conduce to generate a gigantic colonization of air from the earth surface to cosmos space, such resultants of this phenomenon is no air zones and under pressure on earth surfaces, with the intention of making a nasal bleeding, which seeking for a medical intervention aide.

    Biophilic Habitat: Environment Adaptability In Context Of BioEcological Architectural Conception2010In: 3rd International Conference Palenc 2010 jointly organised with EPIC 2010 & 1st Cool Roofs Conference, University of Athens, Greece , 2010Conference paper (Refereed)
    Abstract [en]

    The vital objective of biophilic habitat is to outline attributes and put them into a clear, sensible, organized format so developers, designers, planners, and architects can learn about the importance of a connection to the natural environment in all their building projects. Renew ability is the key to our human range and our prime resource for architecture. Every site is definite as to its location, natural relief, local vegetation, and its macro-microclimate.

    Biophilic habitat becomes an original utterance in social requirement. Moreover, this concept becomes a truly new orientation of human cultural life. Biophilic habitat is a part of a new concept in architecture, that work intensive with human health, ecology and sustainability precepts, such a integrate part of architectural formation which must be in optimal proportion with other buildings material. The position of green covering and its area depend basically on the category of functions that occur under this area. Biophilic habitat produces buildings that use less energy to operate because they feature efficient designs, materials and systems. The majority biophilic architectures have highly competent heating, cooling, ventilation, lighting systems, and appliances. In addition, these biophilic restructures are built of energy-efficient materials carefully installed to prevent the loss of conditioned.

    Abstract [en]

    The house is not only a roof, but also a home, the place where it is formed the moral climate and on which lasts the family spirit. The architectural product, being a product of the human work, a long time user product, like any other product it has not only to be produced but also to get the user’s disposal. The passive and low energy housing represents one of the most consistent concepts of sustainable building and brings with consideration of energy saving concept.

    Presently becomes incorrect work manner when we take the building phenomenon such as (passive and low energy building), detached from the large concept of architecture. Energy in

    passive and low energy building is an important factor; but it has an abstract act without human sentiments. Economy is other factor; all these factors classified such constant value. The human comfort is a vital aim of architecture, and it classified such variable level. The interaction always appears between the energy such abstract act and human comfort such human feeling. The balancing condition is extremely complex. Our job in this investigation is to establish a commune area by architectural conjecture over passive and low energy building.

    Abstract [en]

    Macroclimatic forces have been important factors ever since man first constructed shelter. Throughout architectural history, local buildings have used great in providing the most comfortable internal conditions possible within the exigencies and constraints of local climate. The habitual living way in Iraq is accurately reflected in the households’ organization, in their volumetric configuration, in the forms of useful locations they engender. Houses are compact with interior courtyard; the streets are sinuous and pass through houses volumes. The shady interior courtyard has the effect that the rooms do not communicate directly with the overheated air outside, but through intermediate buffer spaces. In the mean time between courtyard and street at least a wall or a building is always interposed. This isolation from the street indicates concerns for defense. The architectural elements are strongly decorated, reproducing special typologies and traditional houses. The socials relations are strong, a situation which leads to personal-social spaces. The shadow is wanted to create both by means of architectural details and volumes, which have become a landmark of the local architecture specific character, and by means of natural elements (vegetation, water, etc.). The northern orientation is perfect for the summer functional rooms.

    Abstract [en]

    The notion of comfort a luminous ambience refers to the distribution of luminance and chromatic ties on the interior envelope of a space that is one of different fields of vision for a subject within an ambience. Luminance and chromatic ties are at present not often studied as far as comfort in buildings is concerned. Sun lighting and bioclimatic concept is inseparable considerations when designing a building because of the historical and practical significance of natural lighting in architecture. Sunlight is as old as architecture itself. Human life gets sufficient sunlight, in fact, we use more of 90 % of our day indoor, for this reason, specialists are now seeing how architecture can ameliorate the indoor-outdoor links. At present, by biological and technological investigation the trend is to search backwards towards the previous philosophies and advantages of more indoor / outdoor relationship. Plus homeowners who want to have healthy home environments might want to renew the most relevant facts of technology and biology.

    Byggnadsprojektering med BIM-system: En studie om tillämpning och anpassning av BIM-system för den svenska byggindustrin i samarbetet med arkitektkontoret Nylin & Myhrberg GI AB2014Independent thesis Basic level (university diploma), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    The objective of this study is to explore the possibility to create and describe a workflow

    where a BIM-based system is the main tool used to create models/sheets and documents. And

    solve the technical problems that prevent the designer from using BIM effectively. The study

    was conducted by collaborating with the firm Nylin & Myhrberg Architects GI AB, a consultancy

    firm that in the current situation are planning for the implementation and use of the BIM

    system in their production. The focus of the study is to create a workflow that fits the firm's

    business during the transition period, create an IT-manual/BIM-manual, which the company

    will use when designing with Revit Architecture.

    The problem with the system that it is a relatively new system and that may discourage designers,

    consultants and engineers from using the system. There is a lack of guidelines, templates

    and IT manuals that explain how to work with BIM and what should be applied at each

    phase of all the different project phases. There are also difficulties that the company cannot

    influence such as the ability to collaborate with other consultants and designers outside the

    firm that uses different types of BIM platform than the one the company itself use.

    The study was conducted in two phases, a two part research phase in which theoretical

    knowledge about the system, its capacity and operation opportunities compared to the CAD

    system has been studied and reported in this report. And a survey of existing IT manuals (both

    Swedish and foreign) has been used to structure a new IT manual for the firm Nylin and

    Myhrberg. The second phase is a practical phase where a sample project was executed during

    this study. The task was to make an architects model for the project Strandvägen nursing

    home, showing both the existing and the future looks of the building for a construction contract.

    Nylin & Myhrberg are joined bay numerous consultants and designers in the designs

    process, which made the project a perfect opportunity to test the IT manual that was created

    after the first phase of this study.

    The results presents the developed IT manual, which presents different design methods, modeling

    techniques and different kinds of tools to assist the staff at Nylin & Myhrberg in using

    BIM system and collaborate with other consultants who use other platforms or the CAD system.

    The manual is not completed and the user should not expect to get all the answers and

    solutions to all the technical problems. The idea is to develop, update the manual after each

    version of the manual. Users must fill the manual up with new solutions and update the existing

    ones, describe new software and tools and how they should be used. The result also reports

    on how the work in sample project (Strandvägen nursing home) went through and shows

    the difficulties and weaknesses in the system in its current state.

    The conclusion is that the BIM system in it current state is difficult to adapt to the traditional

    Swedish project planning methods and standards, which are built around the CAD system.

    This can reduce the efficiency of the system's tools if we don’t control and regulate the workflow

    and customize the system so that it can cooperate and communicate with other systems

    and platforms without difficulties.

    Abstract [en]

    Approximately 28 000 square meter in Lindvallen, Sälen are to be planed for new cottages, for guest housing, a project commissioned by Skistar. The residential environment shall be designed for disabled people. The purpose of this project is to give Skistar an aspect on how to approach the design of the area with special consideration to disabled.

    The accommodation is intended for guests with or without disabilities who come to spend their holiday and practice alpine skiing. The accommodation is intended for persons who are motion disabled and uses a smaller wheelchair and persons with reduced sight and hearing. Guest accommodation is not included in the norms for disability adjustments. Despite that, the design of the apartments will be in accordance with those rules and recommendations.

    The result is two proposals showing two-storey houses with four apartments in each house, each apartment is made for 8 guests. In the bottom floor there are no thresholds to maximize mobility with a wheelchair. Free space for turning around with a wheelchair exists in the bathroom, hall, kitchen, living room and in one of the bedrooms.

    Apartments intended for visually handicapped are made in a relatively bright environment. Subdued to semi subdued colours are used to avoid reflexions and it is possible to adjust lamp brightness. In apartments intended for persons with a hearing impairment, floor materials such as clinker and parquet flooring are used to avoid unnecessary step noise. An amplifier which sends out a signal to hearing devices is connected to the television.

    The facade material on the house is wood panel and the material on the roofs is either asphalt-impregnated paper roofing or metal. To make it more exclusive shingle can be used as roof material.

    According to the proposed extension plan the housing area includes 15 buildings and a total of 480 beds. The number of parking spaces is 120 of which 15 is modified for use by disabled.

    The result shows details and room functions that are important in an accommodation of this kind. The accommodation is not modified for a disabled person in the sense that this person could manage by herself without difficulties. The reason for this is the assumption that a disabled person will not be alone during a stay here.

    The relationship between office type and job satisfaction: Testing a multiple mediation model through ease of interaction and well-being2018In: Scandinavian Journal of Work, Environment and Health, ISSN 0355-3140, E-ISSN 1795-990X, Vol. 44, no 3, p. 330-334Article in journal (Refereed)
    Abstract [en]

    Objectives This cross-sectional study investigated the associations between office type (cellular, shared-room, small open-plan, and medium-sized open-plan) and employees' ease of interaction with coworkers, subjective well-being, and job satisfaction. Methods A brief survey including measures of office type, ease of interaction with coworkers, subjective wellbeing, and job satisfaction was sent electronically to 1500 Swedish real-estate agents, 271 of whom returned usable surveys. The data were analyzed using a regression-based serial multiple mediation model (PROCESS Model 6), which tested whether the relationship between office type and job satisfaction would be mediated by ease of interaction and, in turn, subjective well-being. Results A negative relationship was found between the number of coworkers sharing an office and employees' job satisfaction. This association was serially mediated by ease of interaction with coworkers and subjective well-being, with employees working in small and medium-sized open-plan offices reporting lower levels of both these aspects than employees who work in either cellular or shared-room offices. Conclusions Open-plan offices may have short-term financial benefits, but these benefits may be lower than the costs associated with decreased job satisfaction and well-being. Therefore, decision-makers should consider the impact of office type on employees rather than focusing solely on cost-effective office layout, flexibility, and productivity.
