Constant Issues

• Undersized (too narrow) ductwork reduces airflow to some areas
  
• Some offices are further from the heating/cooling source, reducing airflow
  
• Differing number of exterior walls (# outside surfaces varies from 0 to 4)
• In large open work areas (e.g., cubefarms) some areas do not receive sufficient airflow and stay too hot / cold / muggy / stuffy

Periodic Issues

• Doubling-up: offices with add’l employees/computers/etc. increases temperature & humidity
  
• Northern exposure (too cold in winter) or Southern exposure (too hot in summer)
  
• Eastern exposure (too hot in mornings) or Western exposure (too hot afternoons)

Randomly Timed Issues

• Conference Rooms & Show Rooms have varying numbers of people
  - Or add’l visitors or electronics in work areas
  
• Sunny day vs. cloudy day changes window heating/cooling
  
• Closed interior door can greatly reduce airflow into a room
• Opened exterior doors lets in outside air, and requires more conditioned airflow
