Innovative Thinking on the Renovation Design of Old Industrial Building Space

The current study investigated the value and significance of the existence of the old industrial buildings, as well as the necessity and difficulty to renovate the design. Combined with successful cases, this study analyzed and showed that one should not only deal with the relationship between the original architectural style and construction of modem cities in the process of renovation design of the old industrial building space. More attention should also be paid to create new space to meet the functional requirements of the modem features, and then complete substantial renovation of old industrial building space through the innovative design. In the use of aesthetic innovative design for the renovation of the old industrial building space, people must respect the space of old industrial buildings as the prerequisite of the renovation design. It is needed to expound the local space reconstruction methods and design principles respectively on the basis of respect. And then one should grasp the whole space and make the structured design and reasonable use according to the new space functional requirements of different functional areas. This paper attempted to learn from environmental art study on the renovation of old industrial buildings space and in terms of innovative design. The authors explored the innovative thinking on the renovation design of old industrial building space through the analysis of the reality.

Evaluation of Energy Consumption for Heating of Industrial Building in-Situ

Because of the high energy demand required to heat a production hall, the aim of this project is to find out whether it is possible to verify the heating consuming process for heating with the standard simplified calculation method [1], especially for cold regions such as Kosice (Slovakia). The energy requirement for heating a case study industrial building was evaluated using measurements and calculations.During the winter period, energy consumption was measured in the selected industrial building according to a validation standard [2]. The building is comprised of two halls. The measurements were analyzed according to the criteria used for validating residential and public buildings, with several regression dependencies taken into account in the resulting evaluation of heating energy consumption. The mathematical dependencies of measured values in real conditions are shown in this paper. In addition, the building’s heating energy demand was calculated according to the Austrian standard [3], ?NORM EN ISO 13790, the simplified calculation method for non-residential buildings. It was investigated whether the measured values could be replicated using this calculation. It was found that the precise definition of the internal heat gains is very important.

A theoretical study on gaseous pollutant flushing of natural ventilation driven by buoyancy forces in industrial buildings

The acceleration of industrialization worsening indoor environments of industrial buildings has drawn more attention in recent years.Natural ventilation can improve indoor air quality(IAQ)and reduce carbon emissions.To evaluate gaseous pollutant levels in industrial buildings for the development of buoyancy-driven natural ventilation,two theoretical models of pollutant flushing(Model I and Model II)are developed based on the existing thermal stratification theory in combination with the mixing characteristics of lower pollutant.The results show that indoor pollutant flushing is mainly dependent on the pollution source intensity and effective ventilation area.The mixing characteristics of lower pollutant has an important effect on pollutant stratification and evolution during ventilation,but it does not change the prediction results at steady state.When the dimensionless pollution source intensity is larger than 1,the pollution source should be cleaned up or other ventilation methods should be used instead to improve IAQ.In addition,the comparisons between Model I and Model II on instantaneous pollutant concentration are significantly influenced by the pollution source intensity,and the actual pollutant concentration is more likely to be between the predicted values of Model I and Model II.To reduce pollutant concentration to a required level,the pollution source intensity should be in a certain range.The theoretical models as well as the necessary conditions for ventilation effectiveness obtained can be used for the ventilation optimization design of industrial buildings.

Spatio-temporal distribution of gaseous pollutants from multiple sources in industrial buildings with different flow patterns

Energy consumption of industrial buildings has remained continuously high,and the environmental quality requirements are also constantly improving.Only by improving industrial environmental control technology based on the transport mechanism of the pollution,can the energy consumption of industrial building environmental control be further reduced,and the environmental quality of industrial buildings can be improved as well.Therefore,after verifying the numerical simulation by experiments,this study uses a self-label method to investigate the spatio-temporal distribution of gaseous pollutants from multiple time-series sources in industrial plants with different length-span ratios.The results show that,the polluted flow in plants with different aspect ratios have different flow patterns:(i)the,,Back-mixingw flow pattern occurs when the ratio of ventilation rate 6 and polluted flow rate at the exhaust height b is less than 1,i.e.,G/L_(p)<1,and(ii)the"One-way"flow pattern occurs when G/L_(p)>1.For plants with the"Back-mixing"pattern,the following source pollutants enter a density stratified environment induced by the retained pre-source pollutants.The flow of following source pollutants released at the same intensity as the precursor source can reach the roof,while those with low velocity and density difference may be blocked during the ascending process.The maximum height zm of the flow of the following source is related to both the initial Froude number Fr_(o)of the following source and the unsteady vertical density gradient of the fluid in the indoor environment dpa/dz.For plants with the,,One-way,/pattern,the flow from the following source enters into an environment with approximately uniform density.Under the condition of positive buoyancy,design parameters of ventilation corresponding to the vicinity of G/L_(p)=1 may be the optimal solution for safety and energy conservation.

Human Resource Controlling and Human Resource Management： Practice of Small and Medium-Sized Building Companies in the Czech Republic

The aim of this paper is to define the nature, present the possibilities, and discuss the problems of using human resource controlling in small and medium-sized building companies. This paper is based on the assumption that expedient human resource controlling is an effective human resource management tool that achieves the required performance of employees and expected competitiveness of a building company. This paper uses the results of a questionnaire survey conducted in November 2013 to analyze human resource management in building companies in the Czech Republic and specify the organization and conditions of human resource management. Some 81 small （less than 50 employees） and 66 medium-sized （50-249 employees） building companies operating in the Czech Republic took part in the questionnaire survey. The results of the questionnaire survey showed the lack of concept and random nature of human resource management in most small and medium-sized building companies. Of course, in terms of the present economic trend, it is above all important for small and medium-sized companies to develop their adaptability to the building market and to be able to deal with a variety of construction works. It is effective human resource management supported by expedient human resources that serves this purpose.

Human Resource Management in the Building Industry： International Comparison

This paper summarizes the results of the international questionnaire survey which took place at the start of 2013 in order to examine, judge, and compare the implemented concept and procedures of human resource management in the questioned building companies operating in the Visegrad Four countries （the Czech Republic, Hungary, Poland, and the Slovak Republic） and the Federal Republic of Germany, and proposes an optimal approach to human resource management in the context of the current and expected economic development. The questionnaire survey was based on the assumption that effective human resource management is a condition of the successful function of each building company and that human resource management is that area of management which distinguishes the successful building companies from the unsuccessful ones. In total, 202 companies from the Czech Republic, 105 companies from Hungary, 100 companies from Poland, 102 companies from the Slovak Republic, and 99 companies from the Federal Republic of Germany took part in the questionnaire survey. The results of the questionnaire survey showed that among the building companies questioned in individual countries, there was no substantial difference in the overall concept and in the partial procedures of human resource management. The implemented concept and procedures in the questioned building companies show significant merits and surprising shortcomings, whereas it is difficult to prove an unequivocal connection between the efficiency of human resource management and the success of building companies. This relationship is determined by a series of other political, economic, legal, social, cultural, technical, demographic, and natural effects which are not related to the efficiency of human resource management or to the performance of the workforce of building companies.

Development of Tender Price Indices for the Ghanaian Building Industry

Tender price indices (TPI) remain an optimum process for predicting tender prices. There have been several indices’ developments in the Ghanaian Building Industry (GBI) to help in cost management practices, for instance, building cost indices, and material indices among others. Notwithstanding, there are no indices for forecasting tender price at the design stage of building projects in the Ghanaian Building Industry. The motivation of this study is to develop tender price indices that would facilitate easy prediction of the initial cost of building projects. Through a thorough literature review and secondary data collection, the index was formulated using Laspeyres with Excel spreadsheet for the actual index. The variables considered include preliminaries and measured work sections which include the substructure, concrete work, reinforcement, masonry, lining/sheathing, window/door/stairs, metalwork, surface finishes, sanitary appliances/fitting and electrical supply/power light system of the Bills of Quantities. The finding of the study shows that on average there is a change in price of about 4.42 per cent within the eight-year period from 2008 to 2016. The study has developed tender price indices for the Ghanaian Building industry for the facilitation of the easy prediction of the tender prices at the initial design stage, however, the indices have an error margin of ±3. The development of these indices will serve as the basis for further development of other indices in GBI such as locational indices and value-based indices for effective cost management practices.

Development of a new connection for precast concrete walls subjected to cyclic loading

The Industrialized Building System （IBS） was recently introduced to minimize the time and cost of project construction. Accordingly, ensuring the integration of the connection of precast components in IBS structures is an important factor that ensures stability of buildings subjected to dynamic loads from earthquakes, vehicles, and machineries. However, structural engineers still lack knowledge on the proper connection and detailed joints o fiBS structure construction. Therefore, this study proposes a special precast concrete wall-to-wall connection system for dynamic loads that resists multidirectional imposed loads and reduces vibration effects （PI2014701723）. This system is designed to connect two adjacent precast wall panels by using two steel U-shaped channels （i.e., male and female joints）. During casting, each joint is adapted for incorporation into a respective wall panel after considering the following conditions： one side of the steel channel opens into the thickness face of the panel; a U-shaped rubber is implemented between the two channels to dissipate the vibration effect; and bolts and nuts are used to create an extension between the two U-shaped male and female steel channels. The developed finite element model of the precast wall is subjected to cyclic loads to evaluate the performance of the proposed connection during an imposed dynamic load. Connection performance is then compared with conventional connections based on the energy dissipation, stress, deformation, and concrete damage in the plastic range. The proposed precast connection is capable of exceeding the energy absorption of precast walls subjected to dynamic load, thereby improving its resistance behavior in all principal directions.
