In the paper the topic of Building Information Technology BIM is investigated. It is new in Polish circumstances technology for construction and for building product industry, which contribute to change and develop level of industrialization. Especially challenge raising from the information and introducing IT technology into daily practice is considered to provide changes in construction branch of economy. In Poland there is the hot need of start to introduce BIM as the common technology for owners of assets, facility management, construction entities, design offices, administration officers and many other players relative to construction data and processes. BIM technology introduction, basing on foreign case studies, results in cost savings, control and time reduction of investment processes and some more advantages. The perspective of digital buildings, digital infrastructure, digital roads, digital railways and digital cities is outlined at the perspective of technology challenge, but simply transfiguration of many fields of personal everyday life, where digitalization is already present and with the question when it will be common in professional activity, particularly in civil engineering.
This article discusses an integrated concept of sustainable building and of Building Information Modelling (BIM) by means of implementation of the Green BIM management method. Apart from presenting this innovative project management method with particular attention paid to solutions applied by Scandinavian enterprises, the article aims at analysing institutional conditions regarding application of the Green BIM within Polish construction companies. Arguments presented in the article are based on results of a scientific review and industry specific publications. Moreover, the article discusses case studies of projects completed with the implementation of the Green BlM method.
Most architects and construction engineers need to use modern energy analysis software for the purpose of improving their design. There is software within the BIM (Building Information Modeling) that are specific to energy which help to get the calculations of energy in an easy way. Building energy analysis studies in Iraq are few and limited and insufficient attention is given to this important stage in building design which is one of the necessary and important stages to obtain a good design In this paper, one of the existing buildings in one of the regions of Iraq was modelled by using BIM modelling software (Autodeck Revit). The energy analysis was then carried out by the (Autodesk Ecotect) software after exporting the previously modelled model. The results obtained are necessary to achieve the best design in terms of energy with the assumption of future changes in buildings that are similar in style and area conditions in order to optimize energy.
