3. 3. Determine the window area’s U-factor (a measure of insulating capacity) and SHGC (solar heat gain coefficient).
4. 4. Estimate the number of occupants and their activities (e.g., cooking, laundry, etc.).
5. 5. Inspect the insulation quality and take note of any energy-saving features (e.g., double-glazed windows, insulated walls, etc.).
6. 6. Consult local climate data to understand the heating and cooling demands specific to Lawson.
7. 7. Use an HVAC load calculation software or manual methods to determine the heating and cooling loads.

System Selection
