If, at the end of any year during the guarantee period, the program has failed to achieve the annual guarantee of savings, the Contractor will pay the Owner the difference between the annual guarantee and the actual savings amount. Savings that are achieved by the upgrades and the modifications in the Agreement prior to completion of the entire retrofit project (construction period savings) will be added to the first year actual annual savings amount. The Contractor and the Owner also agree that if the actual annual savings amount exceeds the annual guarantee amount, such excess savings amounts will be added to the savings for any future year before calculating the savings amount. This guarantee, whether or not exercised, is the Contractor's sole liability with respect to any claim of savings. METHODOLOGY The savings are calculated using Microsoft Excel spreadsheets. All assumptions, variables, and equations are shown on each page. The total annual savings, including, operational savings, are stipulated between the Owner and the Contractor in the Agreement. Stipulated savings are savings that are agreed to be satisfied throughout the term of this performance guarantee. Any changes to the operation of the equipment or systems can be accounted for through calculation and the annual savings adjusted accordingly. The Tables below summarize the guaranteed annual savings from the calculations. This saving guarantee is dependent upon these conditions being met. Any shortfall payments between the Owner and the Contractor will be made within 90 days of the end of each annual period.
