From page 97... ... 97 Appendix D provides detailed guidance on how to measure and verify airport GRF performance. Part 1 describes M&V processes for tracking performance. Read the entire page →
From page 98... ... 98 Revolving Funds for Sustainability Projects at Airports framework with an expected process and deliverables rather than specific approaches. This will allow M&V plans that are appropriate for each project to be developed. Read the entire page →
From page 99... ... Measurement and Verification 99 The GRF M&V protocols should have a process for conducting a performance risk assessment of projects being funded to identify and allocate the performance risk. To help all parties understand the risk expectations, the protocols should require the results of the risk assessment to be displayed in a matrix that defines each performance component and which party is accepting the risk.

From page 100... ... 100 Revolving Funds for Sustainability Projects at Airports The GRF should have a requirement in place that projects applying for funding conduct an M&V assessment to help identify an appropriate party to implement the M&V approach. If an internal airport team approach is desired, that may be defined as the default arrangement; however, provisions should exist to allow exceptions to that rule. Read the entire page →
From page 101... ... Measurement and Verification 101 that can be used for a project when setting those requirements. The following guidelines and references provide information on M&V processes including guidance on selecting a project- or measure-level M&V approach, defining baselines, identifying variables to be measured postinstallation, and savings calculations.

From page 102... ... 102 Revolving Funds for Sustainability Projects at Airports on existing facilities that involve multiple measures with interactive effects between measures. Baselines are typically normalized to account for operating variables that may differ between the baseline and post-installation periods such as weather, number of passengers, or some other quantifiable variable.

From page 107... ... Measurement and Verification 107 in energy use of the affected system. For example, savings associated with the installation of a higher efficiency motor and variable frequency drive with controls to modify operation of a pump from constant volume to variable volume might be determined using the following: Baseline kW and kWh based on measurements of motor during baseline Post installation kW and kWh based on measurements of motor after implementation Demand kW Savings Baseline kW Post installation kW Energy kWh Savings Baseline kWh Post installation kWh ( ) Read the entire page →
From page 108... ... 108 Revolving Funds for Sustainability Projects at Airports need to be taken into account by making adjustments within the simulation models. Using the same example from Option C, savings from a major HVAC and controls upgrade might be determined using the following: - Baseline kW and kWh based on whole facility simulation model Post installation kW and kWh based on whole facility simulation model Demand kW Savings Baseline kW Post installation kW Energy kWh Savings Baseline kWh Post installation kWh ( ) Read the entire page →
From page 109... ... Measurement and Verification 109 • Amount saved to date • Aggregate project expenditures • Aggregate loan repayments • Aggregate rebates received • Aggregate non-project transactions D2.1.2 Project-Level Tracking The tracking of project-level data is another pillar of sound GRF management. The institution should differentiate between proposed projects, for which savings metrics can be calculated for evaluation purposes, and projects that are currently underway or have been completed.

From page 110... ... 110 Revolving Funds for Sustainability Projects at Airports • Lifetime water savings • Lifetime waste savings • To date financial savings • To date energy savings • To date carbon emissions reduced • To date water savings • To date waste savings • Project cost • Project loan repayments • Rebates received D2.1.3 Reporting and Sharing To get a big-picture view of the fund's track record, the GRF management system should also be able to calculate aggregate metrics for the full portfolio, such as total savings and other financial metrics. Other optional functions should also be considered, such as the ability to generate visual representations of project data -- charts and graphs -- that can be important for conveying the impact of the GRF to outside stakeholders.

From page 113... ... Measurement and Verification 113 You will have to decide whether to evaluate proposed projects in the same spreadsheet as projects that have received GRF financing (and whether to keep them all in a single project-level tracking sheet) , or whether to create a separate file.

From page 114... ... 114 Revolving Funds for Sustainability Projects at Airports D2.2.2 Software Solutions Pre-existing software solutions can be used in conjunction with an Excel-based spreadsheet approach, such as using energy tracking software to measure and aggregate energy use across a portfolio, or it can be used to manage the entire fund. At the time of writing this report, there was only one existing software package for GRF fund management (Sustainable Endowments Institute n.d.-k) Read the entire page →
