A Level 1 commercial energy audit is a fundamental evaluation that provides an overview of a building's energy consumption patterns and identifies potential areas for improvement. It serves as a preliminary step in the energy audit process, designed to assess a building's overall energy performance and help building owners and facility managers make informed decisions about energy efficiency upgrades.
ESOS Compliant Audits, Level 1 is the minimum Level of audit for ESOS Compliance.
- Suitable for energy audits of small or medium buildings, facilities, processes or fleets
- Preliminary audit for larger organisations
- Preliminary audit to determine potential improvements that require further Level 2 or 3 detailed study
- Quantitative overview based on overview data
- Can identify areas of focus for energy management resources
- Improved awareness of energy usage, costs and the potential benefits of energy management
- Can identify significant energy uses
- Prepare energy consumption profiles and benchmarks (depending on consumption data available) to indicate current efficiency and to identify high energy consumers or inefficiencies and to identify anomalies in daily, weekly, monthly or seasonal patterns
- Walk through survey to inspect energy users and to identify low cost and easily quantifiable energy savings opportunities
- Identify more capital intensive energy saving improvements at a generic level but not taken to technical resolution
- Typical and Indicative savings and payback periods calculated using common rules and simple payback method (Life-Cycle Costing Analysis where appropriate for ESOS Audits)
- Outline of steps required to generate specific actions that can be implemented (ESOS: Action Plan)
- Identification and basic evaluation of easily implemented low cost opportunities,
- Understanding of energy consumption at a site, system, process or fleet level (depending on available energy and other data),
- Improved awareness of energy usage and the potential benefits of managing energy,
- Determination of more capital intensive opportunities.
