3.3. Energy Calculation Methods<br />
ASHRAE (The American Society <strong>of</strong> Heating, Refrigerating and Air-<br />
Conditioning Engineers) defines all methods and details about <strong>energy</strong> calculations.<br />
EnergyPlus calculations are based on ASHRAE definitions.<br />
Approaches to Modeling<br />
The Methods estimating <strong>energy</strong> use to model for building and HVAC system is<br />
discussed in ASHRAE. There are two approaches to modeling:<br />
1. Forward(Classical) Approach<br />
2. Data –Driven (Inverse) Approach<br />
The objective is to predict the output variables <strong>of</strong> a specified model with known<br />
structure and known parameters. But, in Data-Driven (Inverse) Approach, input and<br />
output variables are known and measured, and the objective is to determine a<br />
mathematical description <strong>of</strong> the system and to estimate system parameters. The system<br />
(mean building) has already been built and actual <strong>performance</strong> data are available for<br />
model development and/or identification in Data-Driven Approach. However, forward<br />
approach is most <strong>of</strong>ten used because <strong>of</strong> ideal in the preliminary design.<br />
EnergyPlus is based on forward simulation model. The first step <strong>of</strong> modeling is<br />
a physical description <strong>of</strong> the building system or component <strong>of</strong> interest. Building<br />
geometry, geographical location, physical characteristics (e.g., wall material and<br />
thickness), type <strong>of</strong> equipment and operating schedules, type <strong>of</strong> HVAC system, building<br />
operating schedules, plant equipment, etc., are the example <strong>of</strong> this description. All these<br />
details about ADM building are explained in this thesis. The peak and average <strong>energy</strong><br />
use <strong>of</strong> such a building can then be predicted or simulated by the forward simulation<br />
model.<br />
