Calibrated Simulation. Savings are determined through simulation of the energy use of the whole Facility, or of a sub-Facility. Simulation routines are demonstrated to adequately model actual energy performance measured in the Facility. This Option usually requires considerable skill in calibrated simulation. If applicable, the predetermined schedule for data collection, evaluation, and reporting is defined in Exhibit A, Article 3-Performance Assurance Services Program.
Calibrated Simulation. Estimate facility energy use based on computer simulation with detailed comparisons made to calibration data. • Equation: • If actual energy data are available for either baseline or reporting period, • Option D is costly due to challenges of accurate computer modeling and calibration. • Common Applications: Where energy data of either baseline or reporting period, but not both, are unavailable or unreliable, such as a new or significantly remodeled or repurposed facility. For purposes of calculations based on measured commodity unit savings the commodity escalation rates set forth in Schedule C (Savings Guarantee) (which may not exceed those set forth in Exhibit 8 (Form of Savings Estimate)) shall be used to establish the energy price for each Savings Year that is multiplied by actual commodity unit savings. Contractor is not responsible for and does not receive benefit for savings based on actual commodity prices.
Calibrated Simulation. Option D involves the use of computer simulation software to predict energy use. Such simulation model must be “calibrated” so that it predicts an energy use and demand pattern that reasonably matches actual utility consumption and demand data from either the base-year or a post-retrofit year. Option D may be used to assess the performance of all Improvement Measures in a facility, akin to Option C. However, different from Option C, multiple runs of the simulation tool in Option D allow estimates of the Measured Project Benefits attributable to each Improvement Measure within a multiple Improvement Measure project. Option D may also be used to assess just the performance of individual systems within a facility, akin to Options A and B. In this case, the system’s energy use must be isolated from that of the rest of the facility by appropriate meters. Measured Project Benefits from the following Improvement Measures will be calculated using Option D: None Customer agrees to notify JCI, within fourteen (14) days, of (i) any actual or intended change, whether before or during the Guarantee Term, in the use of any facility, equipment, or Improvement Measure to which this Article applies; (ii) any proposed or actual expansions or additions to the premises or any building or facility at the premises; (iii) a change to utility services to all or any portion of the premises; or (iv) any other change or condition arising before or during the Guarantee Term that reasonably could be expected to change the amount of Project Benefits realized under this Agreement. Such a change, expansion, addition, or condition would include, but is not limited to: (a) changes in the primary use of any facility, Improvement Measure, or portion of the premises; (b) changes to the hours of operation of any facility, Improvement Measure, or portion of the premises; (c) changes or modifications to the Improvement Measures or any related equipment; (d) changes to the M&V Services provided under this Agreement; (e) failure of any portion of the premises to meet building codes; (f) changes in utility suppliers, utility rates, method of utility billing, or method of utility purchasing; (g) insufficient or improper maintenance or unsound usage of the Improvement Measures or any related equipment at any facility or portion of the premises (other than by JCI); (h) changes to the Improvement Measures or any related equipment or to any facility or portion of the premises required by building codes ...
