Abstract

Data‐based improvement of energy consumption and indoor climate in public buildings – Literature study with focus on the success of approaches Reducing the energy consumption of public buildings is particularly important for achieving climate targets because of the exemplary role they play. A comfortable indoor climate and clean indoor air are crucial for the well‐being and health of building users. Rapid developments in sensors as well as in the fields of data analysis and simulation have led to increasing attempts to achieve improvements in energy consumption and indoor climate using data‐based approaches. The momentum has increased so much that it is becoming increasingly difficult to keep track of which approaches are applied in which situations and with what success. This paper presents a literature study that addresses this issue. For the study, 91 peer‐reviewed articles published between 2014 and 2022 were examined. It was found that the importance of indoor climate in data‐based approaches is increasing compared to that of energy consumption, building‐model‐based simulations are used with increasing frequency, articles deal with very specific issues, and an end‐to‐end consideration that also takes building users into account is usually omitted.

Abstract

From June 13th to 15th, 2022, the 13th International Fluid Technology Colloquium took place in Aachen. The event served as a platform for experts in hydraulic and pneumatic drive, control, and regulation technology to exchange ideas. Despite the COVID situation, 408 participants from 21 countries attended. The colloquium included 116 presentations, a trade exhibition, and covered topics such as tribology, electrification, digitalization, and sustainability. The focus was particularly on the connection between science and industry, as well as the topics of manufacturing and sustainability. Prof. Katharina Schmitz presented the potential of fluid technology in reducing greenhouse gas emissions in her lecture. She emphasized the importance of energy efficiency and the changing public opinion and attitudes among manufacturers. Students increasingly ask questions about the contribution of fluid technology to improving the world. The next IFK colloquium is planned for March 2024 in Dresden and will focus on the diversity in drive architectures and digitalization. A Best Paper Award was given for a research paper on calculating sealing friction in pneumatic components. [Extracted from the article]

3. Proportional-Ventilinsel.

Subjects
*PRESSURE control, *COMPRESSED air, *PNEUMATICS, *ENERGY consumption, *VALVES, *ADHESIVE tape
Abstract

The Proportional Valve Island VTEP from Festo enables extremely sensitive pressure control down to below 1 mbar and reduces the consumption of compressed air by up to 50%. The valve island uses piezo technology, is noiseless, wear-free, and free of copper, nickel, and zinc. It is used in various areas such as wafer manufacturing, battery production, and medical technology. Festo is also developing other products in the field of Controlled Pneumatics, such as the Festo Motion Terminal VTEM and the Proportional Pressure Control Valve VEAB. Piezo valves are used in various areas due to their low energy consumption, noiselessness, and durability. [Extracted from the article]
