IAAC, Dec., 2010 Computation EcotectHugo Carvallo Spyros Stavoravdis
The following ecotect study is related to the studio study of Barcelona 0 emissions, and my focus on the wind behavior. Our barrios are located northwest of Placa Glories (north-west of IAAC), its topography is dominated by ascendant hills forming the Parc del Ginard, and the Parc del Carmel.After several visits to the area of study, we noticed that the wind condition is highly noticeable in all of our barrios.

Barcelona climate summary
Barcelona psychrometric chart
For this Ecotect project, I decide to learn about Barcelona climate specs first. So I downloaded the correspondent .epw file of Barcelona containing information of its climate. Also, through the Psychrometric chart I learn about the specific times of Barcelonas comfort zone.

solar path - radiation areas
To develop this wind study, I had to learn more about heat, and pressure. In reality, wind energy is a converted form of solar energy. The suns radiation heats different parts of the earth at dif-ferent rates-most notably during the day and night, but also when different surfaces (for example, water and land) absorb or reflect at different rates. This in turn causes portions of the atmosphere to warm differently. Hot air rises, reducing the atmospheric pres-sure at the earths surface, and cooler air is drawn in to replace it. The result is wind. (http://www.changetorenewables.com/tag/wind)

monthly wind frequency
The first chart shows one of the windy days during fall, and down below another chart shows the different wind speeds and directions during a regular year in Barcelona.
wind related comparison
average wind speed
The image on the left is a graph show-ing a comparison between wind frequency, average wind temperature, average relative hu-midity, and average rainfall.Again, all related to the wind study.
This image shows the average weekly summary of wind speed, notice that it sometimes reaches the speed of 40 km/hr (11.11 m/s)
Average temperature during a week in Barcelona.
The following images (the next 2 pages) taken from Ecotect show different wind calculations. The levels of calculation go from 25 m, and 100 m approximately above ground. The first image shows vector lines representation of wind direction. The second image is about the airflow rate.The last image is about the cell pressure concentration.
isThrough these images, we can take a look to the wind ecotect interpretation of its behavior. Doing this, we can determinate different point of views to proposed passive or mechanical techniques.

ecotect offers the opportunity to mea-sure the level of visibility depending of the given conditions.The 2 first images show how -- selecting the facades, ecotect measures the urban visibility of the facades. The last image, shows how much vis-ibility ecotect can measure within the interior of a room towards the outside --in this case, how much visibility is in relation to the mountain.
At the end, this green energy cannot only serve to ventilate interior spaces, but also to generate the necessary power to produce electricity.And finally, wind power devices can be located on the hills of the mountain, and mainly where the lowest parts of the hills meet. Also, in the future, a re-location or de-formation of the urban condition towards the mountain can be proposed to help to speed up, and harvest the wind energy in pro of their community.
