Large CommercialThe Energy Performance Protocol for Large Commercial (EPP-LC) is designed for large scale projects that involve whole building retrofits and other projects involving multiple measures with interactive effects where the cost of improvements and size of savings justifies greater time and effort in pre-and post-development energy analysis as well as high performing projects with sufficient savings for pre- and post-retrofit meter data yields where savings are of greater magnitude than noise. Even with these qualifications, the EPP-LC Protocol will not be appropriate for every building. The protocols elaborated here lean heavily toward a whole building metered pre- and post- retrofit data-driven (IPMVP Option C-type) approach. However, such an approach may not be appropriate for buildings that do not have relatively stable fundamental usage patterns – e.g., buildings that are characterized by large and frequent changes in the type of space use, unpredictable and inconsistent schedules. In such cases, alternative methods not covered here may be required. |
Standard CommercialThe Energy Performance Protocol for Standard Commercial is for commercial retrofit projects consisting of multiple measures costing typically under $1MM where engineering requirements must be scaled to fit performance risk. These projects are typically considered "high performing projects" where the projected energy savings typically cover the project investment cost
The EPP - Standard Commercial allows for the use of various open-book calculation methods, and rely on partial and full measurement and verification of the energy use and system(s) to which an energy conservation measure (ECM) was applied (Option A: Retrofit Isolation: Key Parameter Measurement and Option B: Retrofit Isolation: All Parameter Measurement). However, these approaches may not be appropriate for buildings requiring a more holistic approach including the use of an energy model to determine energy savings and/or IPMVP Option C: Whole Facility approach for measurement and verification of savings. In the case of a building requiring such a holistic approach. In this case, the M&V protocols found in the EPP-Large Commercial Protocol should be used for these specific components of project development, or in its entirety. |
Targeted CommercialThe Energy Performance Protocol for Targeted Commercial (EPP-TC) is designed for projects that involve individual or smaller sets of energy conservation measures (ECM) that focus on only one or a handful of building end-uses, such as lighting, controls, HVAC replacement, etc. EEP-TC makes allowances for alternative and simplified approaches to technical underwriting and engineering, providing a standardized framework that is scaled for energy efficiency projects with less complexity and financial risk. These targeted projects typically affect only a portion of the building’s end-uses, and have greater budget constraints, such that requirements for baselining, savings projection, commissioning, and measurement and verification, must be targeted and streamlined. While important to the project’s development and success, these components must be scaled appropriately, such that their inclusion in these targeted projects do not overly burden the project budget. |
