This is the amount of energy that will be saved if you invest in the new technology. There are a couple of key points to note: 1. Every building is different and there are many factors which drive the actual savings so this is only a direction guide on the savings available. 2. The % represents the energy that will be saved on that piece of equipment, it isn’t the energy of your whole building. As an example, if you upgrade to LED lighting, this wont reduce your whole buildings energy by 70%, just the amount of energy consumed in the building.
