ASHRAE I
ASHRAE Level 1 Energy Audit
An ASHRAE Level 1 Energy Audit, also referred to as a Preliminary Energy Audit, is a screening-level assessment developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). This audit is designed to identify energy efficiency opportunities without the cost or complexity associated with detailed engineering analysis.
Scope of the ASHRAE Level 1 Energy Audit
The audit provides a high-level evaluation of building energy use and includes the following components:
Utility Data Review
Analysis of 12 to 24 months of energy bills to identify usage patterns, seasonal trends, and baseline energy performance.
On-Site Walk-Through Assessment
A visual inspection of major building systems, including:
Heating and cooling (HVAC) equipment
Lighting systems and controls
Building envelope components (walls, roofs, windows, doors)
Domestic hot water systems
Identification of Energy Efficiency Opportunities
Identification of low- and no-cost measures, as well as operational improvements, that have the potential to reduce energy waste.
Preliminary Savings Estimates
High-level estimates of potential energy savings to help prioritize identified opportunities.
Benchmarking
Comparison of building performance to similar building types to provide context and perspective.
Next-Step Recommendations
Guidance on whether a more detailed ASHRAE Level 2 Energy Audit or a targeted analysis is appropriate.
Important to know
An ASHRAE Level 1 Energy Audit serves as an initial evaluation. It does not include detailed engineering calculations, energy modeling, or investment-grade financial analysis. Its primary purpose is to support early-stage planning and informed decision-making.
