Course Description

As interest in performance verification and model validation continues to grow, Energy Modelers should consider familiarizing themselves with new IMPVP Option D approaches. IPMVP represents a set of internationally accepted protocols for quantifying project related savings, including the Option D approach. Calibrated energy models form the foundation of all IPMVP Option D savings estimations. Option D activities involve generating a calibrated ‘as operating’ model, and the subsequent replacement of components of the calibrated model to estimate project savings.  In addition, Option D is the only IPMVP option which can be accomplished post facto. This powerful attribute allows IPMVP adherent savings to be determined for nearly ANY energy efficiency project. Until recently, cost-effective methods for quantifying the accuracy of model calibration efforts have been difficult for practitioners to develop and/or execute, preventing Option D from being applied to projects in any scalable manner.  However, recent advances in the OpenStudio suite of tools provide new ways for users to interact with a calibration framework that can be used for either new construction or retrofit projects – including incorporating uncertainty analysis. Course attendees will be exposed to this framework, allowing them to explore the uncertainty of input parameters and discover sometimes unexpected solutions that might lie within a large parameter space. Students will use OpenStudio tools to configure an analysis scenario involving calibration, apply parameter sensitivity analysis to determine parameters of influence, and execute a calibration exercise where solutions are discovered.  The course will be jointly taught by PSD’s Chris Balbach and NREL’s Brian Ball
