If additional analysis casts substantial doubt on the life cycle cost analysis results, a Federal agency should consider obtaining more reliable data or eliminating the building energy or water system alternative.","path":["Title 10—Energy","CHAPTER II—DEPARTMENT OF ENERGY","SUBCHAPTER D—ENERGY CONSERVATION","PART 436—FEDERAL ENERGY MANAGEMENT AND PLANNING PROGRAMS","Subpart A—Methodology and Procedures for Life Cycle Cost Analyses"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-10.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:24:09Z","sha256":"c6633267efa5919623bc7be12ef7c8ffe44e96592c8f8dabde67a66cf8ea9a08","source_id":"us-cfr","stale":true,"prev":"us/10-cfr-436.23","next":"us/10-cfr-436.30"},"notice":"GroundRules: Original legal text.
