Auditing Software for Multifamily Weatherization

This session explores the common use cases and capabilities of the two Weatherization Assistant Suite of Tools energy audits suitable for multifamily (NEAT and MulTEA). MulTEA is a DOE-approved audit tool for use in the Weatherization Assistance Program for all multifamily buildings with individual heating and cooling systems. The ability to audit buildings with a central boiler has now been programmed in MulTEA. This presentation provides an overview of updates to MulTEA, focusing on use cases with a central boiler and associated retrofit measures that can now be evaluated in MulTEA. Likewise, the National Energy Audit Tool (NEAT) has been a core energy auditing tool in the DOE Weatherization Assistance Program for over three decades. The flexibility built into NEAT that makes it a standard choice for single-family residential energy auditing also provides capabilities for analysis of low-rise multifamily buildings. This presentation lays out a pathway for using NEAT to complete energy auditing of select low-rise multifamily buildings.
