Analysis:

For  the Barcelona “0 emission” project we extracted a part of our whole barrio to test the mapping technique which after confirmation can be appllied to the whole area; our intention consists in showing which places are most frequented by tourists in order to identify and show where most energy has to be spent in order to maintain the city as a tourist attraction. Hotels, resturants and museums are being considered as the potential emitters and attractors of tourists.

In the selected area highest tourist densities occur in “Las Ramblas”, around the Catherdral, at axis from  Jaume I  to Via Laietana and around the Picasso museum; the color code informs about the vicinity of hotels, restaurants and museums.

Based on general data on efficiency for  the three categories hotels, restaurants and museums we trace the total consumption of energy for the mapped entities to find out which ones have the higghest energy saving potential. Hotels and large museums stand out to be the biggest energy consumers.

We also analyzed motorized traffic  and parkings as indicators of increased CO2 emission; though this diagram identyfies areas of increased traffic in the area the total traffic is still low compared to other parts of the city. For this reason this diagram will probably discarted for the final analysis. Proposal: Based on the tourist density city services can adapt their maintenance of the city. Areas with high density will receive more attention, energy and money for maintenance services than others. Like this a street with many tourists will be cleaned more often than a street with lower touristic density. The biggest energy consumers ( hotels an large museums) should be working in a selfsufficient way. Systems to achieve that should be integrated into the same buildings.
