A novel omni-direction-guide-vane (ODGV) that surrounds a vertical axis wind turbine (VAWT) is designed to improve the wind turbine performance. Wind tunnel testing was performed to evaluate the performance of a 5-bladed (Wortmann FX63-137 airfoil) H-rotor wind turbine, with and without the...

Buildings and other engineered structures that form cities are responsible for a significant portion of the global and local impacts of climate change. Consequently, the installation of building integrated renewable energy sources such as photovoltaic or solar thermal systems on building...

Oscillating Water Column based wave energy plants convert wave energy into low pressure pnuematic power in the form of bi-directional air flows. Air turbines which are capable of rotating uni-directionally in bi-directional air flow, otherwise also known as self-rectifying turbines, are used to...

This paper deals with the detailed flow analysis of impulse turbine with experimental and computed results for wave energy power conversion. Initially, several turbulence models have been used in two-dimensional (2-D) computational fluid dynamic (CFD) analysis to find a suitable model for this...

Mit der gegenwärtigen Reform der Gemeinsamen Agrarpolitik (GAP) verfolgt die EU insbesondere das Ziel, neben der Einkommensstützung den Beitrag des Agrarsektors zum Schutz des Klimas, der Umwelt und der biologischen Vielfalt zu erhöhen. Hierfür wird in der neuen GAP ab 01.01.2023 in der 1....

Despite significant efforts, investments and some local successes, the EU's Common Agricultural Policy (CAP) has not succeeded in halting the loss of farmland biodiversity. To address these weaknesses, the CAP post-2020 proposes a new "Green Architecture" comprising, inter alia, compulsory...

This research briefly reviews the definition and the principles of green architecture, making a comparison between the global green building rating systems in respect to materials only. These systems are the [1, 2]Green Pyramid, BREEAM (Building Research Establishment Environment Assessment...

Constant change in current market and social conditions has triggered the demand for a more adaptable building stock. The capacity to assume and accommodate change has thus become a new requirement for buildings. At the same time, there is a growing demand for more environmentally conscious...
