Large MultifamilyThis protocol focuses on large multifamily buildings (multifamily is typically defined as residential structures with five or more units, a typical threshold used within the housing industry for multifamily rental properties). The protocol is intended for:
Even with these qualifications, the Energy Performance Protocol - Large Multifamily (EPP-LMF) will not be appropriate for every multifamily building. The protocol elaborated here leans 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, or unpredictable and inconsistent schedules. In such cases, alternative methods not covered here may be required. |
Standard MultifamilyThis protocol focuses on standard multifamily buildings (multifamily is typically defined as residential structures with five or more units, a typical threshold used within the housing industry for multifamily rental properties). The protocol is intended for: ● Standard Multifamily Projects, multiple measure projects costing typically under $1MM and therefore engineering requirements must be scaled to fit performance risk ● High Performing Projects, projects where the projected energy savings typically cover the project investment cost The EPP - Standard Multifamily allows for the use of various open-book calculation methods, and relies 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, that may require the use of an energy model to determine energy savings, as well as an Option C: Whole Facility approach for measurement and verification of savings. In the case of a building requiring such a holistic approach, the M&V protocols found in the EPP-Large Multifamily Protocol should be used for these specific components of project development, or in its entirety. |
Targeted MultifamilyThis protocol focuses on multifamily buildings (multifamily is typically defined as residential structures with five or more units, a typical threshold used within the housing industry for multifamily rental properties). The protocol is intended for Targeted Projects, including single or multiple measure projects costing typically under $200,000 and therefore engineering requirements must be scaled to fit performance risk. The EPP - Targeted Multifamily allows for the use of various open-book calculation methods, and relies 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, that may require the use of an energy model to determine energy savings, as well as an Option C: Whole Facility approach for measurement and verification of savings. In the case of a building requiring such a holistic approach, the M&V protocols found in the EPP-Large Multifamily Protocol should be used for these specific components of project development, or in its entirety. |
