The cost to create an M&V program for Option D, according to IPMVP, is influenced by the following:

• size and complexity of ECMs, systems or building;
• accuracy of the difference between actual and estimated energy use (a less accurate calculation costs less in man-hours); 
• simulation software and its associated complexity;
• and the extent and sophistication of submetering.
