Commercial Energy Audits

Elliott Energy has extensive experience with Level 1, 2, and 3 energy audits. We have audited over 100 facilities, totaling over 10 million sq. ft. all across the country and abroad. The following types of facilities have been audited:

·         Office Buildings

·         Schools

·         Hotels

·         Dormitories

·         Multi-Family Residences

·         Resorts

·         Libraries

·         Fire Stations

·         Food Processing Plants

·         Laboratories

·         Medical Research Facilities

·         Industrial Manufacturing Plants

·         Sports Arenas

·         And More…

As far as what is expected at each level of audit, see below:

Level 1

ASHRAE Level 1 energy audits consist of the following:

·         Building walkthrough to familiarize yourself with major energy systems

·         Utility bill analysis

·         ENERGY STAR® benchmarking

·         High-level recommendations for energy savings

·         Final report, typically in Word or PDF form

The purpose of an ASHRAE Level 1 is to get a sense of what may be possible for energy savings. The walkthrough will show major systems (ex. chiller/boiler system, water source heat pumps, etc.), type of lighting, and general controls. The utility analysis and benchmarking will tell you how much energy the building is using and how that energy consumption compares to buildings of a similar type and size.

Using that baseline level of information, a qualified engineer can make some simple observations and recommendations for potential energy savings.

Level 2

ASHRAE Level 2 energy audits consist of the following:

·         All aspects of a Level 1 audit

·         Detailed inventory of all energy using pieces of equipment, including all lighting

·         Review of all building control systems

·         Meeting with on-site staff to discuss building systems, maintenance issues, and other potential concerns

·         Sophisticated energy calculations to determine where the energy shown in the utility bills is going

·         Further energy calculations and financial analysis to distinguish with potential energy conservation measures (ECMs) are worth pursuing

·         Can estimate initial costs for ECMs

ASHRAE Level 2 audits are the most common form of energy audits. This method will provide the highest output-to-cost ratio.

Level 3

ASHRAE Level 3 energy audits consist of the following:

·         All aspects of a Level 2 audit

·         Tracking actual equipment energy over periods of time using data loggers

·         Using much more intensive energy calculation methodologies, typically simulation software that meets ASHRAE standards for accuracy

·         Getting real quotes from qualified contractors for potential projects

·         Evaluating feasibility of implementing an ECM (ex. how will a chiller fit into the current mechanical room, etc.)

ASHRAE Level 3 audits are the most accurate form of energy audits, but also the most cost intensive. These audits are best suited for scenarios in which a very high level of precision is necessary.
