The procurement or purchasing process in your organization has an important effect on both the amount of energy you use and on its cost. You should consider this opportunity in preparing your purchasing methodologies.
Most organizations routinely procure the services of other companies to help them with a variety of tasks.
When selecting these services, it is very worthwhile evaluating their capabilities in the area of energy efficiency knowledge. The savings in energy can outweigh the savings in hiring the cheapest service provider.
