Energy Calculations 101: Let’s Take the Mystery Out of Determining Energy Savings
Determining if a project will result in energy savings is a critical step in energy project development and is often the deciding factor in the go/no go conclusion. If a project will result in real energy savings with a favorable ROI, that project is more likely than not to get approved. So, making accurate energy savings calculations is crucial to pushing projects forward. But many Energy Managers rely solely on their vendors and contractors to calculate the potential energy savings. This can be a dangerous gamble. Vendors and contractors often exaggerate savings claims in order to make the sale. Then, when the savings don’t happen, the Energy Manager is left holding the bag.
But there is no reason that Energy Managers shouldn’t be able to do their own energy calculations even if they haven’t been professionally trained. Taking a few AEE courses is a great way to gain the calculation knowledge; or they could even buy and use expensive calculation software. But understanding the basics of energy calculations is easy and doesn’t require a ton of investment in time and/or money. And determining the potential energy savings for most projects is very straight-forward—requiring only a few mathematical algorithms.
This presentation will explore those algorithms and present real-life examples that energy managers can use for their own project work. Attendees will come a way with an energy engineering calculation toolkit that contains the most common mathematical algorithms that energy engineers use on a daily basis.
