During an Investment Grade Audit, energy auditors conduct an in-depth analysis of the building's energy usage patterns, systems, and components. It is a very detailed investigation, often concentrating on opportunities or issues identified in a previous Level 1 or Level 2 Commercial Energy Audit.
An IGA includes examining the efficiency of HVAC systems, lighting, insulation, windows, and other relevant factors. The auditors collect extensive data on energy consumption, perform engineering calculations, and may use advanced computer modeling to simulate energy savings and project financial returns.
A Level 3 Commercial Energy Audit, or Investment Grade Audit is the most comprehensive commercial energy audit with significant input from the organisation, and consideration of business strategies in mind. It is suitable for whole sites, processes, systems or fleets, and is generally only cost effective for organisations with high energy spends or institutions with targeted capital-investment grants.
An IGA is also applicable at the system level (e.g. compressed air), and analyses detailed energy and process data to identify and evaluate opportunities with more rigorous investigation. It includes the identification and evaluation of a range of coherent and specific energy performance improvement opportunities, with identified costs and benefits, including quantification of “non-energy” gains.
• Detailed understanding of energy consumption and use
• Identification and analysis of energy saving opportunities, including no cost, low-cost and capital investment measures to include energy and non-energy benefits
• Preliminary equipment design or process improvement and detailed cost requirements
• Data for energy review purposes
• Examination of metering systems and recommendations to address data gaps
Uncover energy efficiency opportunities with a Level 1 Commercial Energy Audit.
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.
Delve deeper into your energy systems with a Level 2 Commercial Energy Audit.
A Level 2 commercial energy audit is a comprehensive assessment conducted to evaluate the energy efficiency of a commercial building in greater detail.
Reduce your energy consumption and costs with our Commercial Energy Audits.
A commercial energy audit is an assessment of a building or facility to identify opportunities to reduce energy use, lower carbon emissions and save money.
