The long-range and short-range WindScanner systems (LRWS and SRWS), multi-Doppler lidar instruments, when combined together can map the turbulent flow around a wind turbine and at the same time measure mean flow conditions over an entire region such as a wind farm. As the WindScanner technology is novel, performing field campaigns with the WindScanner systems requires a methodology that will maximize the benefits of conducting WindScanner-based experiments. Such a methodology, made up of 10 steps, is presented and discussed through its application in a pilot experiment that took place in a complex and forested site in Portugal, where for the first time the two WindScanner systems operated simultaneously. Overall, this resulted in a detailed site selection criteria, a well-thought-out experiment layout, novel flow mapping methods and high-quality flow observations, all of which are presented in this paper.

This article evaluates Europe’s building sector’s circular economy (CE). This industry is responsible for 42% of energy consumption, more than 50% of extracted materials, 30% of Europe’s water and waste generation, and 35% of greenhouse gas (GHG) emissions. This study focuses on peer-reviewed articles from Scopus and Web of Science databases. Of the first 1750 publications, 2.9% were eligible for a full-text reading and analysis. Most of the trending studies, 92%, promote the circular economy concept through construction materials rather than analyzing the impact of the construction sector on the environment and finding solutions for better implementation, and 41% promote recycling and reuse as the only options. New Design solutions are in 12% of the studies, six-fold more than Law and Legislation, which is only 2%. Finding an optimal combination of assessing the life cycle of buildings and components and searching for different ways of managing the Construction and Demolition Waste at end-of-life is between 33% and 39%. Ultimately, CE proposed frameworks for the building industry based on 10R principles variations were evaluated. An alternative framework for a circular strategy for the building industry that focuses on Upcycling, replacing the Recover principle is presented.
