Theme C: Education and Market TransformationThis method considers an underground cavity that already exists below thebuilding basement structure, and consists of 15 tubes with 1m of diameter and 17mof length placed alongside under the construction, as shown in the Fig. 12 and 13.Eventually, the potential on using wind turbines inside this passage, for energygeneration for this proposition, can be quantified.-1.00+1.00-1.000.00courtyard 01(S)groundtubesFigure 12: Building 01 ground floor plan showing underground connection.courtyard 01(S)courtyard 05(N)-1.00turbine+1.000.00Figure 13: Vertical section across Building 01 showing underground connection.Building the CFD models.The same software was used to perform CFD simulation. A 2D model was created,in order to analyze the air flow effect through the underground passage. In order toreach more accuracy on the results, the size of the cells used on this model variedfrom 10 to 30cm.Starting this analysis with the results obtained from the simulation of the windoriginating from South (from the right of both images showed on Fig. 15), it is628
