The purpose of this research was to develop simple thermal load smart graphs for rapid thermal load estimation. These graphs were generated in order to facilitate a quick estimation of the thermal load. This is especially important when computer-aided heating, ventilation and airconditioning (HVAC) design software is unavailable. Hundreds of calculations have been carried out using various heat transfer equations and an hourly analysis program (HAP) generated graphs displaying the external and internal sensible and latent heat gains of analyzed spaces. These smart graphs are very user friendly; non-technical individuals can easily calculate the thermal load using these graphs. The smart graphs are time-saving and give results more accurate than thumb rules. In fact, they give a total thermal load estimate that is less than few percent di®erent from the estimate generated using commercial software programs.
