How accurate are the projected energy savings?
It depends. Most of the time it is extremely accurate. Sometimes we need to make assumptions. When we do so we always try to err on the conservative side. Our projections are designed to be intentionally less than anticipated. Most of the time our clients save more energy than we originally projected. We calculate the cost of your energy. However, your cost of energy may change. Energy costs are strongly influenced by politics as well as supply and demand. As a general rule, your cost of energy is increasing – sometimes very quickly. The savings we forecast are always conservatively based upon your historical cost of energy. In reality we expect your energy costs to increase above what we forecast. During a lighting assessment phase, we assume you are using energy efficient ballasts. If you’re actually using non-energy efficient fixtures, as many facilities are, then your actual savings will be much better. Once again, we conservatively estimate your fixture wattages.
