This final rule consolidates the Physical Needs Assessment (PNA) rule (FR-5361) with the Public Housing Energy Audit rule (FR-5507). With respect to the energy audit, the rule would distinguish between "core energy conservation measures" (ECMs) that must be addressed and "advanced ECMs" that may be addressed. The rule would also establish minimum requirements for energy auditors and moves the energy audit requirements to a different part of HUD's title of the Code of Federal Regulations. With respect to the PNA, the rule would require public housing agencies to project current modernization and life-cycle replacement repair needs of its projects over a 20-year period, rather than a 5-year period, to better coincide with the useful life of individual properties and their building components and systems to ensure the long-term viability of the property.
