ASTM E1369

ASTM E1369 is a technical guide for selecting techniques to treat uncertainty and risk in the economic evaluation of buildings and building systems. It helps users compare decision-making methods when cost, performance, and financial outcomes are not fully certain. By giving practical direction on technique selection, the standard supports more consistent economic analysis and better-informed planning for building-related investments, upgrades, and lifecycle decisions.

What is ASTM E1369?

ASTM E1369 is the Standard Guide for Selecting Techniques for Treating Uncertainty and Risk in the Economic Evaluation of Buildings and Building Systems. It is intended to help users choose appropriate methods for handling uncertain inputs and risk factors within economic studies. The guide is relevant when evaluating building projects, systems, or alternatives where estimates may vary and decision quality depends on how uncertainty is addressed. ASTM E1369 is generally used as a decision-support document rather than a prescriptive testing standard.

Where is ASTM E1369 used?

This guide is commonly used in building economics work, including planning, design review, retrofit analysis, and lifecycle cost evaluation. It may support evaluations of whole buildings or individual building systems where economic results depend on uncertain assumptions such as future costs, performance, or timing. ASTM E1369 is useful for engineers, analysts, owners, and specifiers who need a structured way to choose risk and uncertainty treatment techniques during project assessment and comparative analysis.

Why is ASTM E1369 important?

ASTM E1369 matters because economic evaluations are only as reliable as the methods used to manage uncertainty. Selecting an appropriate technique can improve consistency, reduce guesswork, and make comparisons between alternatives more defensible. For procurement, planning, and quality-focused decision-making, the guide helps teams align their economic analysis approach with the level of uncertainty involved. That can support better risk awareness and more credible building investment decisions.
