Abstract

The roofs of the buildings present a very valuable source

of renewable energy: wind. Similar to the study of the

perfect location for wind generators in the natural

environment, we need to have models for

characterization of wind in the urban space to optimise

the locations of the mini wind turbines in that space as

well as the chose of the most appropriate type. The

scientific study of the implementation and optimisation

are the basis for a line of research developed by our

group in recent years. Its most important results and main

conclusions are presented in this paper. The separation

angle is greater near the edge of the roof of the building

and varies with wind speed. The higher the building, the

greater the separation angle reached, reaching even 90°.

For low buildings that angle will be imperceptible. The

more rugged is the area near the building the lower the

angle of separation. The wind turbines have to be placed

always at a height above the separation bubble, in order

to avoid the slow speeds as well as significant

turbulences. Furthermore it is noteworthy that the wind

turbines will benefit from an increase of 20% of air

velocity compared with the wind at the same location if

there was no effect of the building. That is, the urban

space provides an extra increase of wind power, provided

that the location of wind turbines is optimised.
