Interpolation for building performance evaluation tool

Hello,

I am trying to create a tool which estimates the performance of a building in terms of energy consumption and comfort. For this purpose i have precalculated the monthly results of the building's performance(in csv files) for certain parameters of the building: 4 orientations (NESW), 4 different window to wall ratios (20-50-80-100%), 4 locations, 4 different construction profiles, 4 different types of window, 3 options for shading, 4 options for lighting and 3 options for controlling the shading system (24576 precalculated csv files!).

My problem is this: i need to create a matlab function that is going to calculate the building performance for all orientations (0-360 degrees) and for all window to wall ratios between 20-100% (not only for the 4 different orientations and 4 window to wall ratios) while the rest of the input parameters are not changing. To my understanding, i need to have an interpolation routine, but the problem is that i have no such experience and i only have 1 week to finish.

Can anybody give me possible suggestions for dealing with this problem? Should i use something like scatteredInterpolant or griddata?
