The pace of changes in the construction industry is constantly accelerating. It includes 3D modeling, utilization of drones, 3D printing and virtual or augmented reality. Augmented reality combines something real, such as existing buildings, with expanded 2D or 3D digital information about individual technologies or planned changes, and the actual projection of individual elements into a given (even hidden) space. It can be a key for improving project engineering processes, subsequent maintenance or more efficient renovation procedures. Virtual and augmented realities need 3D building models, i.e. incorporation of building information modelling. Building information modelling (BIM) is a modern and efficient solution process that incorporates the entire building life cycle, based on a realistic model and information. Individual building technical equipment, i.e. including heat sources, to a certain extent influence the internal structure of individual buildings, particularly in the case of a more complex structures. The article describes some of the modern technologies that can be applied to the administration, maintenance and implementation of building technical equipment. Such technologies can also help when deciding about the most suitable heat source for a given building. The article points out the benefits of incorporating these modern technologies.

BIM is a concept and also a method currently applied throughout the world in the modern building construction. The impact and benefits of the BIM method are clear across all stages of the life cycle of buildings (project, realization, operation, demolition). The longest and most expensive phase of buildings life is the operation and usage part. Many common aspects and linkage of processes between the BIM method and the facility management, i.e. a modern asset management method, can provide greater efficiency for these activities, help reduce the cost of required building operations and maintenance and save time for individual activities. The BIM can be understood as an information management of buildings. Many common elements can create a synergy of processes related to the management of buildings. The article discusses these aspects and emphasizes the listing of the basic data and processes that are necessary for mutual interconnectedness.

Modern geographic information systems are able to visualize almost any information in their maps. Important is the data that the GIS should visualize. This data consists of information from the cadaster, passports or city plan. This paper discusses the possibilities of visualizing climate data based on a sensory network. The results can be used in the planning and development of the city. Internet of Things is a modern part of the Smart City concept that forms the basis of the modern city. The world’s most modern cities are equipped with hundreds or thousands of sensors. The data can be used for planning and development of the city. The result is more efficient facility management of the city, administration and operation, strategy and planning. In conjunction with building information management, more precisely city information management, significant savings can be achieved. Climatic conditions measure various institutes outside the influence of the city. For efficient use of data, the possibility to operate these sensors operatively and deploy them according to their own requirements and needs, the city should have its own sensor network for measuring climatic conditions.
