Sarah Wenninger

Sarah Wenninger serves as Regional Energy Coordinator for the PBS R1 National Contracts Team within the General Services Administration’s Public Buildings Service, where she leads strategic procurement initiatives to modernize federal facility energy systems. In this role, she manages the acquisition of technical services that support energy efficiency, sustainability, and infrastructure resilience across federal buildings, focusing on consulting services that inform design, planning, and implementation of energy performance improvements. Her work directly advances the agency’s mission to deliver high-performance, cost-effective physical infrastructure through expertly structured contracts that align with federal energy policy and sustainability mandates. Wenninger collaborates with a broad network of management consulting firms and technical service providers specializing in energy systems analysis, building performance modeling, and federal compliance frameworks. While no single contractor dominates her portfolio, she consistently engages firms with demonstrated expertise in federal energy codes, ASHRAE standards, and DOE guidance, fostering long-term partnerships with vendors who bring technical depth and regulatory familiarity to complex facility upgrades. Her contracting approach emphasizes performance-based outcomes and integrated service delivery models. Wenninger’s procurement activity reflects a strong preference for open competition, with 100% of her acquisitions issued as non-set-aside contracts. This indicates a focus on selecting the most technically qualified providers regardless of socioeconomic status, consistent with the complexity and scale of energy systems work requiring specialized credentials and federal experience. While small business participation is not prioritized through set-asides, her solicitations remain accessible to all qualified vendors under full and open competition protocols. Her primary procurement focus is on NAICS 541618 (Other Management Consulting Services), encompassing energy audits, retrocommissioning, utility incentive coordination, and sustainability planning for federal facilities. She specializes in acquiring advisory services that inform capital improvement decisions, support Energy Independence and Security Act compliance, and enable data-driven energy performance contracting strategies across the federal real estate portfolio.
