Done this, we can start our work.


3_Click on Analyze and then click on Location to specify where the model is located. We need to set the weather center that is more similar to our building (short distance and same or similar altitude). Once you identified the position, click on Import Site Imagine to put this information on first drawing level.

The east face of the court, in which is located all bedrooms is located in a good point during all the day. In fact the zone doesn’t need a strong solar radiation. On other hand, this location allows to radiation to enter in bedrooms, through the fixtures. On south-east corner il located the kitchen withliving room on south west corner. This rooms is located on a good point too, because the radon is costant during all the day. In the end the building has a specular form. If on south face we have a favorable situation , on the north face , the situation is completely opposite , cause of energy problems and in some points, the presence of mold .

On the north side of the building chosen , is Piazza Testaccio . We thought it would be interesting to study the relationship between the square and the building ( north facade ) . In particular , during the summer solstice , the building does not create any protection on the square , as the shading is very low . In the winter solstice , however , the shadow of the building continues towards the square , obscuring an important part of it during the period in which there is the most need of radiation. We can conclude that the location of the building from the square was not designed according to the modern criteria.

Exposure north facade during the winter solstice and summer solstice:
