Building Automation and Control network (BACnet) is network protocol specifically designed for automation and control of technologies in buildings. Typical applications include heating, ventilation, air conditioning, lighting, access control and fire detection. It provides standardized framework for organizing and sharing information between networked control devices [1, 2]. Interoperability is provided through object model of information items and their properties and associated services. Flexibility is provided by a range of supported networking options from serial line to Ethernet and internet connection. However, BACnet does not guarantee interchangeability of products from various vendors and every controller or other product may require vendor-specific programming and configuration tools.

This article presents a simulation analysis conducted at the Institute of Environmental Engineering at CTU, as part of the international exercise IEA EBC Annex 82. The aim of the joint exercise, which involved more than ten international research teams from different sectors, was to test and compare different approaches towards achieving energy flexibility in buildings on the basis of a unified exercise assignment. The Czech team based its study on a comprehensive simulation of the energy behaviour of buildings, including a detailed numerical model of the heating, hot water preparation, cooling and ventilation systems. The model was used to study the building potential for providing energy flexibility and future responsibilities of building operators in the context of smart energy grids.

This paper focuses on fire safety solutions for warehouses according to ČSN 73 0845. For comparison, the requirements set by the legislation in Portugal and Canada are analysed, as well as the requirements set by the NFPA (The National Fire Protection Association). The different approaches are compared and the most important differences are mentioned, especially in relation to current trends in warehousing. Finally, a software tool created in the Python programming language called “Warehouse Operations Group” is introduced. This tool is used to classify the fire compartment of a warehouse into a group of warehouse operations according to the method set out in Annex A of ČSN 73 0845. The process of determination simplifies and eliminates any errors that may enter into the calculation.

The article largely copies the fourth chapter of the book Transport infrastructure management in context, which was recently published by VŠLG o.p.s. in Přerov. The entire book captures the links between the construction of transport infrastructure, its management and traffic operations in a unique way. All mentioned pillars of the book are described in an economic context with a focus on many information contexts.

By digitizing and automating processes throughout the building life cycle, the goal is to optimize the use of information so that it can be easily used either to reduce waste from buildings (waste prevention) or to have sufficient information about the materials and products used in the building at the end of its life cycle or as part of various renovations or retrofits. At the same time, improving the planning and management of the waste generated is a key effort. The paper presents the results of the European RECONMATIC project in this area, which progressively links information efficiency approaches with BIM processes. As such, the project has a broader focus and represents a paradigm shift in the management of C&D materials, from the traditionally conservative approach to C&D waste, to a similarly conservative approach of the construction industry, to construction production that seeks to achieve high waste recovery rates, and to the adoption of a responsive approach to waste recovery. The technologies to be used in this project (creating and working with a digital twin of the building, blockchain-based applications, precision prefabrication, efficient sorting through automation and robotics, etc.) are part of the themes that the project focuses on.
