“…Laboratory trials (TRL 3) were conducted all three conversion principles. The experiments proofed the concepts and demonstrate that the heat generation is positively correlated with viscosity [48,52,53] and temperature [46] of the working fluid, and with rotational speed of the wind turbine [46,52,59]; the experiments also demonstrate that the heat generation is negatively correlated with the volumetric flow rate of the working fluid [46,62].…”

“…To make it easier to identify pertinent literature, we provide a brief description of every paper classified by category and conversion principle (Table 2). We recommend the articles from Jwo et al [11] and Ždankus et al [48] to familiarize with compression-based windthermal energy, the articles from Liu et al [57] and Serov et al [54] to familiarize with friction-based windthermal energy, and the article from Chen et al [62] to familiarize with induction-based windthermal energy. The proposed application of a windthermal energy system from Okazaki et al [38] is by far the most-cited article and is worth reading.…”

“…Similar to wind to power converters, direct drive [27,42,46] and gearbox-type [43] windthermal converters are proposed for both vertical- [31,48,67] and horizontal-axis [9,38,42,43] wind turbines.…”

“…Friction losses increase by the fluid's velocity raised to the power of two, converting kinetic energy into heat. The installation of an orifice or throttle valve within the pipe system further increases heat generation [27,[46][47][48]. We assume that this application is called "liquid extrusion" [28,40] or "liquid squeezing" [40] despite that the terms were neither elaborated within the provided literature nor found in further research.…”

Windthermal turbines convert wind directly into thermal energy. Albeit it is an uncharted field of research, the overall system efficiency and costs of fully developed windthermal turbines are promising; since they can contribute to a sustainable energy transition. We identify the current state of the art of windthermal conversion principles, technology maturity, applications, substitutes, advantages and disadvantages. To scope relevant literature, we follow the Joanna Briggs Institutes selection and screening process resulting in 61 relevant publications from which we identified three main conversion types, namely compression-, friction-, and induction-based windthermal devices. These devices can directly supply thermal energy for space heating or industrial processes, work as a component of wind-powered thermal energy systems, short WTES, or can substitute any conventional or renewable heat device. Although heat is the lowest form of energy, windthermal applications could provide cheap renewable energy that can be stored easily enhancing security of supply. However, these technologies are currently on laboratory-scale, and we suggest scaling up the existing prototypes to engineering-scale. Finally, due to a missing general terminology, we propose to establish one of the terms windthermal energy, ventothermal energy or anemothermal energy to distinguish these specific wind energy conversion technologies.

Inevitably, the 21st century has initiated a series of developments in the construction industry, leading to its digitalization and resulting in a series of innovative approaches and practices. At the same time, the construction industry, being one of the main global environment polluters, should fulfil well-established, as well as novel, sustainability requirements in order to evolve in harmony with the rising concerns on the availability of natural resources. This overview study aims to present the main developments, research, and scientific challenges in the field of sustainable construction, emphasizing the field of energy. The study aims to present a state-of-the-art scientific discussion on the sustainable built environment topic by analyzing cutting edge topics in the fields of building elements and whole building energy assessment, of indoor air quality and low carbon buildings, as well as on sustainable energy systems and smart buildings. The study also presents the state-of-the-art in existing tools which are adopted for the assessment of the sustainable built environment, including the use of digital tools and building information modelling for the energy assessment of the built environment, as well as the application of Life Cycle Assessment on building-related processes. Cross cutting issues related to the analysis of the building sector in the Industry 4.0 era, such as sustainability management topics and environmental geomatics are also discussed. The study concludes in those fields which will be of interest of the scientific community in the following years, towards achieving the goals of the sustainable development of the building sector.
