Prof. Ing. Daniel Kalús, PhD.*, Ing. Matej Kubica* * (Department of Building Services Faculty of Civil Engineering, STU in Bratislava, Slovak Republic, ABSTRACT Many ingenious inventions were developed during modern history, but their spreading failed due to inconvenient timing or weak propagation. In our work we processed our own survey and other researches about future constructions in European Union in order to indicate possible technological trend, which will be present in building constructions. In territory of EU can be seen great repulsion of investors and designers in usage of renewable sources of energy. However, according to research, this disinterest will gradually disappear and there will be suitable conditions for our developed device. The article contain chronologically described development, schemes of connection, method of measurement and regulation, possible process of production and future applications, direction in development of compact station is indicated. One of interesting novelties will be diagnostics of performance of whole system connected to compact station – that will bring better accuracy into controlling and it will be possible to integrate this invention into heating systems, which already exist.

INTRODUCTION Work with description, measurement and optimization of compact stations of the new S.M.A.R.T. type. Self-monitoring, analysis and reporting technology or S.M.A.R.T. is a technology monitoring system that detects and reports security reliability indicators in an attempt to predict failures. The new smart-type compact heat station is a technological device with a control unit that can monitor, analyze, detect and predict failures, ensure the communication and collaboration of the technological components of the compact heat station with each other but also with external devices using software specially developed for this purpose remote control. The technological development of technology in every field of science and technology is heading towards total networking. The reason is to use a huge amount of information to make decisions much faster and more accurate. Tight connection of technological components of the compact station hot new smart type, heat sources, end elements energy systems, people like users to be achieved by reducing energy performance of buildings, increase the economic efficiency of technical building equipment, reduce operating costs and save the environment long term sustainable manner. The compact heat station being developed also includes connections to heat sources and energy storage in addition to the connection and transfer nodes. At present, efforts are being made to reduce operational and investment costs to a minimum by using renewable energy sources. Energy-efficient buildings no longer need traditional heating systems, but are increasingly being used to heat and cool large-area building structures. Unconventional energy systems, which are proposed as part of the construction, have been taking their lead and have been involved in building construction since the design itself. Work is currently focused on market research and the assessment of potential future use of compact equipment and specification of its parts. The overall layout of a compact station from commonly used components adds new possibilities for its use, namely diagnostics of the heating system in renovations and buildings with incomplete factual design.
