1-Investment Grade Energy Audit OHSA 032526.pdf

This is an Investment Grade Energy Audit document prepared for the Housing Authority of the City of San Antonio, Texas, in support of a HUD-approved self-managed energy performance contract phase III (EPC III). The audit evaluates energy and water conservation measures (ECMs) across Opportunity Home San Antonio's portfolio of properties, with recommendations for lighting retrofits, low flow plumbing fixtures, appliances, building envelope improvements, furnaces, water heaters, boilers, and related energy and water savings improvements. The audit serves as the technical foundation for the Pre-Construction and General Contracting Services solicitation, providing detailed baseline energy consumption data, conservation measure specifications, and projected utility savings that will inform contractor proposals and project implementation.

The energy audit establishes the performance metrics and financial framework for the EPC III project, which utilizes energy and water savings to finance the cost of conservation measures without requiring upfront capital expenditure by the Housing Authority. The audit includes detailed engineering analysis, measure-by-measure cost-benefit calculations, and guaranteed savings projections that will support the performance contracting approach. As an investment-grade audit, the document provides the technical rigor and credibility necessary to secure third-party financing and validate energy savings guarantees required under HUD's energy performance contract guidelines.
