GreenBoxEnergy performed detailed analysis of the operation for a period of time analyzing the supply and demand profiles for each day day of the week to determine where there was operational waste. Then in small increments, temperature changes were implemented to assure that savings could be achieved without impact to the tenants.
Kapiolani Bel-Aire is a small to medium sized complex with 96 units and a highly efficient hot water heating system and the results have still been impressive. We have achieved a sustained savings of 15% of operational costs.
