At DEXMA, we are firm believers in the 10% Rule for Energy Efficiency. To understand it, let’s take a real example from one of our clients. Jo Burns manages a mid-sized supermarket chain with retail locations across the UK.

Jo’s trying to figure out how much of her budget she should invest in energy efficiency. She knows that her supermarket chain spends roughly £50,000 per month on energy bills. This represents a total annual energy cost of £600,000.

If Jo wants to save more money on energy, she can using The 10% Rule to estimate the total project cost of an energy management initiative.
