L1 and L2 audits refer to different levels of assessment, primarily used in energy management and technical compliance, representing a progression from basic to detailed analysis. L1 (Level 1) audits act as a preliminary screening to identify quick energy-saving opportunities, while L2 (Level 2) audits provide an in-depth, detailed analysis of facility systems to identify comprehensive improvements.
The Level-2 audit starts with the findings from the Level-1 audit and examines the building energy systems in detail in order to define a number of potential energy-efficiency improvements. This will include the Building Envelope, Lighting, HVAC, Domestic Hot Water, Plug Loads, and Compressed Air and Process Uses.
An L1 chain audit provides a comprehensive security assessment of a Layer 1 blockchain to identify vulnerabilities and recommend ways to fix them.
Tiered expertise model: L1 handles basic troubleshooting using predefined scripts, L2 manages complex escalated issues requiring deeper expertise, L3 resolves critical problems through developer collaboration.
L1: This terminal connects to the first phase of the power source, typically carrying the active line in single-phase systems or one of the three phases in three-phase setups. L2: Linked to the second phase or neutral line, L2 completes the input circuit.
Tier 2 Support (L2)
These agents are responsible for handling technical problems that require deeper expertise, detailed diagnosis, and backend system access. Tier 2 support typically demands a specialized skill set to resolve such issues, including: Advanced troubleshooting.

What happens during an audit? Internal audit conducts assurance audits through a five-phase process which includes selection, planning, conducting fieldwork, reporting results, and following up on corrective action plans.
4 levels of audit opinions
Effective Level 1 Assurance is essential in mitigating the risk of serious incidents. ORR Assurance. Deep Dive. Intelligence gained from safety conversations, self-assurance and technical assurance was neither collated or analysed locally, nor used to feed into route level or national analysis.
ASHRAE Level 2 – Energy Survey and Analysis
The next step for most facilities is the ASHRAE Level-2 audit/assessment. The Level-2 project starts with the findings of the Level-1 audit, and evaluates the building energy systems in detail to define a variety of potential energy-efficiency improvements.
The 5 toughest concepts in auditing: Materiality, Independence, Risk Management, Professional Skepticism, and Culture & Governance. The 5 Hardest Concepts in Auditing! Some audit concepts are universally tough because they require judgement, balance, and deep understanding.
Type 1 – focuses on the design of controls at a specific point in time, whereas Type 2 assesses the operational effectiveness over a period. Type 2 – requires more rigorous assessment, involving the testing of controls to validate their effectiveness in achieving the specified TSC.
