Open source, also known as open source software (OSS), refers to different types of software whose source codes are publicly accessible and can be viewed freely. The concept enables openness and free collaboration in software development and has now spread to all areas and industries. Depending on the open source license, the source code of software can also be modified and passed on. In development, this means that it is not always necessary to start from scratch, but that existing codes can be used, which in turn enables cost-effective solutions. The fact that anyone can check the source code means that errors and harmful components of the code can be detected more effectively. Open source promotes innovation and the free exchange of knowledge. The opposite is proprietary software, the use and modification of which is severely restricted.
Thanks to open source software, IoT technologies in particular can be used efficiently in building automation and continuously improved. Another advantage is the promotion of energy-efficient, sustainable solutions, whose integration and adaptation to the needs of users is considerably simplified and can be implemented more cost-effectively. Open source platforms for data analysis simplify the management and intelligent control of maintenance work and the monitoring of building safety. The building life cycle can thus be made more sustainable and cost-effective.
