When designing a large open warehouse space, several factors need to be considered to meet the intended purpose and budget. These include the height of the space, which can reach up to 40 feet, requiring careful consideration of insulation values (e.g., R-11 for the roof, R-5 for walls) and the need for proper ventilation to maintain air quality (e.g., outside air at 0.06 cfm/sqft). Dock doors and their dimensions should also be accounted for, and the use of air curtains can be beneficial. Determining the heating requirements depends on the purpose of the space, such as preventing freezing of fire sprinkler heads or meeting minimum heating needs for a small number of employees. Setpoint temperatures may vary, from 55F for basic heat to 65F in winter or 75-78F for comfort conditioning.
