The National Association of State Energy Officials (NASEO) seeks a qualified organization to perform a state-wide residential building energy code and resilience field study in Arizona. The selected subcontractor will conduct field data collection services according to the U.S. Department of Energy (DOE) Residential Building Energy Code Field Study Methodology and a resilience field study methodology under development by the project team, which includes NASEO, the Southwest Energy Efficiency Project (SWEEP), the Florida Solar Energy Center (FSEC), and the National Renewable Energy Laboratory (NREL), with support from the Pacific Northwest National Laboratory (PNNL).
The subcontractor will visit approximately 150-200 single-family homes under construction and pre-occupancy throughout Arizona over two project phases. Phase 1 data collection, occurring in spring 2026, will represent 40 percent of the total sample (approximately 80 homes), with the remaining data collection occurring in Phase 2 pending DOE continuation. The subcontractor must identify residential construction sites, obtain access from builders and owners, conduct inspections using established methodologies, perform quality control and quality assurance reviews, and transmit data to NASEO and PNNL in required spreadsheet formats.
Key data collection requirements include seven energy code compliance metrics: envelope tightness (ACH at 50 Pa), windows (U-factor and Solar Heat Gain Coefficient), wall insulation (assembly U-factor), ceiling insulation (R-value), lighting (percent high efficacy), foundation insulation (assembly U-factor), and duct tightness (CFM per 100 square feet of conditioned floor area at 25 Pa). The subcontractor may also collect additional information such as code compliance path, insulation installation quality, home size, and number of bedrooms. Resilience metrics, numbering approximately 7-10, will be determined by the project team and shared with the data collector. The subcontractor will work with SWEEP as the main local contact for local implementation, quality control, quality assurance review, and identifying substitute jurisdictions as needed.
Important dates and milestones include: RFP issuance on November 14, 2025; written proposals due December 5, 2025 at 11:59 p.m. ET; proposal evaluation completion estimated December 12, 2025; proposal award notification estimated February 6, 2026; and contract awarded/contractor start date estimated February 27, 2026. Questions on the RFP must be directed to Liepa Braciulyte no later than November 21, 2025 at 11:59 p.m. ET. All prices, costs, and conditions shall remain firm and valid for sixty days commencing on the proposal due date. Upon contract award, all prices shall be firm for the duration of the contract. Phase 1 contracts will be initially awarded, with Phase 2 contingent on successful Phase 1 performance and DOE approval.
