A general model for cooling design.

To increase of diffusion on the bioclimatic architecture is necessary to make the calculation Method easy to use for designers. In particular the available calculation method for analytical, based on transfer functions or finite elements method or those made for simplified calculations are generally very complex to use. Is necessary to develop methods of analytical type and simplified more "friendly" to use. The present work shows the results obtained with a simulation model in respect with the previous conditions to estimate heating and cooling systems performance and also a simplified method in which operative graphs are used, for passive solar systems calculations and in progress partial results of a method for passive cooling.
