Technical standards

    Standards and protocols play a central role in the context of building automation and also in the energy transition in the building sector. Norms are intended to establish standards and guidelines that ensure that buildings are designed, constructed and operated in accordance with the latest technological developments and sustainable principles. These standards cover aspects such as thermal insulation, energy efficiency of heating, ventilation and air conditioning technology as well as the use of renewable energy sources. They serve as a guide for architects, builders and construction industry professionals to create buildings that meet the highest standards of energy efficiency, helping to reduce energy consumption and environmental impact.

    With the help of modern building automation and its intelligent control and monitoring of building technology and systemsenergy consumption can be optimized. This requires protocols that define specific communication and control standards to ensure seamless interaction between different building automation components. These protocols enable the networking of lighting, heating, cooling, ventilation and security systems to regulate energy consumption and maximize comfort for residents. They ensure that buildings operate efficiently by collecting and analyzing data and triggering automated actions based on predefined algorithms. Standards and protocols are therefore key elements that contribute to successfully implementing the goals of the energy transition in the building sector and intelligent building automation.

Norms

On this page you will find different technical norms, which were recorded in autumn 2022. These were recorded through research in software catalogs, standards databases and in energy transition building research projects. These are German, Austrian, European or international standards and guidelines for the planning, construction and/or operation of ventilation, drinking water, hot water, challenges in the development and implementation of drainage, heating, cooling and other energy systems in buildings. Other technical standards, such as soundproofing, lighting, and gas installation, are also included. The following aspects were recorded for each norm:

  • Name and full title of the norm
  • Short description – What is it about?
  • Source – where can the standard be obtained from?
  • Link – a link through which the norm can be accessed (possibly purchased).

Protocols

Various protocols that were recorded in summer 2023 are described in detail on the page. These were compiled through research in the relevant specialist literature, in documentation of hardware and software, and in documents from energy transition building research projects. We have selected 12 commonly used and modern protocols and summarized the following characteristics for them:

  • Name of the protocol
  • Transmission media – How is data transferred between the various components and devices within the system (wired, wireless or wired & wireless)?
  • Supported transmission media – how are signals transmitted?
  • Related standards – specific standards to which each protocol can be assigned.
  • Open-Source-status – is the protocol public and freely available?
  • License fee – Is there a fee to cover the costs of use and/or certification?
  • Network topology – what is the physical and logical arrangement of devices and components in a network?
  • Implemented security mechanisms – whether and what mechanisms are implemented in the protocol to ensure data security?
  • Bandwidth – the capacity of the communication channel to transmit data between the various components of the system.
  • Frequency – the frequency, wavelength, or carrier frequency used by the wireless communication devices in the system.
  • Range – the maximum distance over which communication can be maintained between the various devices and components of the system without the signal strength becoming too weak.
  • Implemented OSI-layer – the application of the layers of the OSI reference model for communication between the various components of the system.
  • Levels of building automation – the hierarchical structure of a building automation system.
  • Data model architecture – how do you add information or attributes to an object?
  • Discovery – whether the protocol has the “discovery” function to automatically identify devices during data transfer?
  • Multi Master – Can several master devices act at the same time?
  • Priority – Procedure for how the changes or updates are made.
  • Typical application – If applicable, exemplary application.
