Additionally the following data was considered Height of 3 00 m for the reservoir percentage of the lot will be occupied by the reservoir 5 of the total area of the lot and simulation with 10 particles and 10 interactions. Table 9 shows the results. The commercial opportunities of the use of the simulation are related to investments that can be considered infeasible or not so feasible which could discourage investments in rainwater harvesting systems.

Volumes and NPV using Rain Toolbox Besides that the method proposed a factor that was not considered elsewhere. Economic variables are also important to stimulate the use of alternative sources of water mainly for non-potable uses. Case 4 - Commercial building industrial plant The fourth and last case is a building in an industrial complex in the city of Paulinia located only 5 km from the other cases analyzed in this work. This building is comprised of 4 pavements in the first there is a kitchen and a refectory in the other the administrative offices of the complex can be found. Each pavement has two men s and two women s restrooms. On the ground level aside from the four restrooms there are two changing rooms one for each gender. The kitchen has a capacity for 250 meals day and a total of 180 workers. The covered area is m2. The building has a m2 garden and an impermeable area of m2.
