  >strong vibes of manual j In the simplest terms, they're all derived from the heat transfer equation of Q=U*A*deltaT so all load calculation models will seem similar to an extent. It ultimately comes down to how nuanced you want the model to be. >does it take into consideration heat gain/loss by walls and insulation through the day Yes, it has factors like heat gain coefficient that are used in conjunction with U-factors, weather, and the orientation of the structure. Most of the more widely used models include those aspects.
