Abstract: This paper shows the example of the blast furnace project risk assessment project documentation. Evaluation is performed by expert Universal Matrix of Risk Analysis (UMRA) and in the second part will be aligned with the evaluation using RPN index. Individual analysis of the research questions will reveal whether and to what extent it is necessary to deliver it to the weighting of individual factors or whether it is sufficient to use a constant scale factor input data.

Abstract: The paper reflects the possibility of utilization of methods and proceedings used in risk assessment for area different from nowadays usage. Risk determination is customary for large and significant constructions within the feasibility study. Used procedures and methods can be applied very well in some cases of experts and authorized proceedings, such as setting the sequence of buildings acceptable for reconstruction of objects in defined group, or setting the coefficient for specification of claim amount arisen in the construction in the case of time-independent price.

Abstract: For the interaction with certain equipment engineers and scientist do have a need to build a wide range of tools under a dramatically short amount of time. This is what is referred to as BRESET (Building REmote SEnsing Technologies), a development environment created to solve issues, to have an accelerated productivity and be available for continuous innovations. The designed system is based on a credit card size minicomputer which have had brought a revolution to the computing industry, namely the Raspberry Pi, and on a prototyping platform called as Arduino - together ArduPi. From these two units the Raspberry Pi is bound to serve as the brain of the system, while the Arduino is ready to be used as an intermediary element to communicate with the sensors. The units are planned to send data through the widely known and used I²C protocol. This certain combination allows observations to be done for various fields. The connected sensors may be analogue or digital, industrial or DIY type at the exact same time. For example it would be possible to measure humidity, temperature, energy consumption and many more, with the ArduPi. The paper therefore focuses on prototyping in the field of building physics.

Abstract: BIM (Building Information Model) as a process (in the world) is known since the seventies, but with increasing pressure from investors to reduce construction costs can assume its massive use. On large construction sites, it could not be managed without it in the future. Next post in the basic range analyzes the current situation of the use of BIM at home and abroad, in the use of options in modern architecture and also indicates which methods to streamline the current design activity.

Abstract: The objective of this study is to examine the possibility of using DSS in the engineering design of a special group of building constructions: 'cladded roofs'. These are roofs whose cladding is the same as the façade’s, giving buildings a homogeneous appearance. For architectural impression the roof is made of unusual materials and complex structures thus cannot be designed with traditional guidelines. The goal of using DSS is to facilitate and simplify the range of possible materials and structures, to assist and expedite finding the optimal version and to reduce the likelihood of design flaws. In addition to eco-efficiency in production, transportation, and energy consumption of buildings, we hold it to be important to reduce the amount of materials used to a necessary minimum. [1] To achieve this all materials should be used at places where their specific characteristics prevail most effectively. The criteria for applying DSS for ‘cladded roofs’ is the successful structuring of the necessary constructional data and variations. We propose a method to generate numerous proposed solutions and rank them based on their technical performance and value. The result is a kind of 'guided decision-making' which may be an important aid in the design of nonstandard structures.

Abstract: This contribution illustrates recent efforts in the research project SEMERGY, a computational environment, which incorporates semantic web technologies to support building design and refurbishment optimization. A major part of the necessary information for energy efficient building planning is implicitly available in the World Wide Web. However, this theoretically valuable repository of information cannot be practically used, given its ill-structured nature. SEMERGY addresses this very problem through a number of developments. Specifically, SEMERGY: 1) embeds a comprehensive building data model, 2) incorporates an Ontology for building product data, 3) deploys a rule-based logic for identification of valid building construction alternatives, 4) provides an easy-to-use optimization procedure evaluating energy demand, environmental impact, and investment costs of alternatives, and 5) offers a web-based Graphical User Interface. The present contribution provides a general overview of the whole project and documents the state of its development.

Abstract: In the present paper we propose a solid theoretical frameworkfor the automatic parametrization of the cost-optimal refurbishment of arbitrary buildings.The parameters describe the structural parts of the building that can be modified or replacedduring the refurbishment process.The methodology also provides the cost-optimal refurbishment costand the corresponding smallest possible total life-cycle operation costconstrained by the available technological and economical limitations.The theory is implemented into the EnergOpt expert system providingfast and accurate answers to cost-optimization problems appearing in common practical applications.The system is built on firm mathematical foundations that is supported by state-of-the-artoptimization algorithms capable of finding good optimums in a short amount of CPU time.The modular structure of the IT implementation facilitates effortless localization in different countries.The application of the system may considerably contribute to the decrease of theheating energy consumption and the corresponding environmental load of the building stock.The practical potential of the technology is demonstrated by the energetic analysisof an existing family house.

Abstract: This paper deals with an actual problem of covered historic building atriums in Slovakia and their adaptation to the new function concerning building physics parameters. The aim of this contribution is to quantify the parameters of the new covered atriums regarding the sound parameters. The executed measurements in selected atriums were compared with the standard values (reverberation time, flutter echo) considering their new function (cultural, social, health).

Abstract: The concept of minimalism in residential buildings accompanied mankind from the beginning of the existence of primary dwelling. The contribution analyses and summarizes historical theory of minimalism in housing and compares it with current architectural realizations, new trends, and experiments in the future in term of sustainability, economy, efficiency and savings. Financial economy and efficiency of construction is not resulting automatically from the minimalist concept of residential buildings. A residential building, which is minimalistic may not be sustainable, or energy efficient yet.

Abstract: Projects based on small prefabrication or self-build concepts can help ensure the basic human right to adequate housing in progressive, affordable homes. These projects should represent a flexible system capable of responding to new challenges and application of new technologies, while maintaining the status of socially-oriented housing.
