Symphony Cycle Guarantee

For a limited period of offer, it is guaranteed that Symphony Cycle will at least deliver savings that cover its license costs in its first year of use. Should the first year’s savings be less than those required to cover the cost of the license, then the licensee will be reimbursed the difference between the value of the savings achieved and the cost of the license. The AUP (Average Unit Price) of the savings is deemed to be the same as that used in the license calculator at the time of license issue.

To invoke the guarantee, the licensee must demonstrate that Symphony Cycle has been applied correctly and present metered energy consumption data that clearly shows the shortfall in savings realised specifically on account of Symphony Cycle’s performance.

Symphony Cycle Savings

The amount of energy (kWh) savings is similar for buildings of different ages of the same size, location and occupancy patterns. Savings of 10% to 20% on building heating energy and HVAC (Heating, Ventilation & Air-Conditioning) electricity are typical for consumptions associated with more modern buildings. The license calculator uses science based factors and local geographical/weather data to estimate the likely savings.

The AUP value of the energy savings is based on typical national commercial energy prices at the time the license is calculated. The license fee is therefore fixed. There is no change to the license fee should the licensee achieve savings than differ from those of the license calculator.
