This presentation is a high level overview of design side management. DSM includes energy efficiency, load management and demand response. It is important to articulate clearly on the goal of a particular program or policy. Energy efficiency and load management are sometimes confused. Clean demand response is emphasized, avoiding the use of back-up generators that add emissions to the airshed, and may do so when the air quality is already unhealthy (i.e., peak hours in the summer may coincide with peak pollutant concentrations, especially in the US Eastern Seaboard and California).
