Abstract
Today's market in micro-wind turbines is in constant development introducing more efficient solutions for the future. Besides the private use of tower supported turbines, opportunities to integrate wind turbines in the built environment arise. The Integrated Roof Wind Energy System (IRWES) presented in this work is a modular roof structure integrated on top of existing or new buildings. IRWES is build up by an axial array of skewed shaped funnels used for both wind inlet and outlet. This inventive use of shape and geometry leads to a converging air capturing inlet to create high wind mass flow and velocity toward a Vertical Axis Wind Turbine (VAWT) in the center-top of the roof unit for the generation of a relatively high amount of energy. The scope of this research aims to make an optimized structural design of IRWES to be placed on top of the Vertigo building in Eindhoven; analysis of the structural performance; and impact to the existing structure by means of Finite Element Modeling (FEM). Results show that the obvious impact of wind pressure to the structural design is easily supported in different configurations of fairly simple lightweight structures. In particular, the weight addition to existing buildings remains minimal.

Loads are better distributed, where vertical forces are more efficiently lead to the columns and horizontal forces to the beams
Summary
Depredation of fossil fuels, global increasing energy costs and demand force today’s society to change the energy need and generation to ensure the quality of future life and our essential ecosystems [1,2,3]_ENREF_2_ENREF_3. To address this current and future need, more effective solutions for harvesting renewable energy sources on the short term are needed. Governments, scientist and communities are looking for feasible solutions to the aforementioned problem. Compared to other energy sources, onshore wind seems to be the future largest contributor of renewable energy technologies [5]. Key factors of its advantage are that it’s largely available on almost any locations, drastically reduces carbon costs, suffers from zero geopolitical risk associated with supply and infrastructure constraints, as well as energy dependence [6]
