A typical vertical axis wind turbine (VAWT) consists of two or more airfoils all attached to a single central axis. The wind turbine style most commonly found in renewable energy is the horizontal axis wind turbine (HAWT) that have a high energy production efficiency in exchange for requiring large amounts of land and air space. Alternatively, a VAWT can function in low speeds and in smaller less typical locations. As a result, novel VAWT designs are researched to improve their energy efficiency. An example of a novel VAWT is the concentric counter-rotating VAWT investigated theoretically using the 2D computational fluid …

Mitigating global climate change is a major contemporary topic of research and is of major interest to today’s societies. Developed countries the top contributors to the destruction of the climate with buildings in these countries being one of the reasons. Buildings in developed countries account for 20-40% of the total primary energy consumption. This high-energy consumption produces approximately 36% of the total CO2 emissions since fossil-fuels are the primary source of energy in almost all developed countries. To combat this, researchers have investigated wind energy harvesting technologies that produce electricity while also being considered “green”, or low carbon dioxide emitters. …
