Energy Audits

An energy audit determines where, when, why, and how energy is used and identifies energy savings opportunities to help reduce energy consumption and operating costs, as well as reduce the carbon footprint. The audit includes all building systems which directly or indirectly affect energy consumption are part of the study and include but not limited to heating ventilation and air-conditioning (HVAC), mechanical, electrical, plumbing, process equipment such as walk-in freezer/ cooler, building envelope components such as an exterior wall, roof, windows, doors and last but not the least the building automation systems with sensors and controls which control all equipment.

Our experienced and qualified energy auditors work closely with building owners, staff and other key participants throughout to ensure the accuracy of data collection and consultation in adopting various energy efficiency recommendations based on client needs.

The audit typically begins with a review of utility data and benchmarking of your building’s energy use against similar buildings to set the stage for the audit.

The main outcome of an energy audit is a list of recommended energy efficiency measures (EEMs), their associated energy savings potential, and payback calculations to justify the financial investment. Our auditors work with you from the word go till the projected savings are realized so you get the maximum value from the project.

Since there is a cost associated with energy audits, it makes financial sense to start with a high-level walk-through audit and identify if it is worth spending additional dollars towards a more detailed audit. Walkthrough energy audits cost less and identify no-cost or low-cost recommendations and a general roadmap for future planning.

Many of these recommendations such as building automation setting change are easily implemented by operations and maintenance staff, and energy savings are seen almost immediately. Resulting cost savings can then be put toward more detailed audits on facilities where there are bigger savings opportunities.

Detailed energy audits are more comprehensive and performed where it makes financial sense based on a walk through audit.  We help you to obtain rebates from utility companies and government programs to cover some of the costs of the audit as well as upgrades. 

At Green Globe, we conduct energy audits as per the guidelines of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and also in consultation with manufacturers of building systems in order to adopt the latest technology for the benefit for our clients. 

Levels of Energy Audits 

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)  defines three levels of audits. Each audit level builds on the previous level.

As audit complexity increases, so does thoroughness of the site assessment, the amount of data collected, and the detail provided in the final audit report. This effort can translate into higher energy savings.

We always recommend starting with level 1 audit which is the least expensive and do levels 2 and 3 in progression only for buildings where it makes financial sense based on opportunities.

Level I Energy Audit : 

Level I Energy Audit, also referred to as a walkthrough audit and includes site assessment and utility bills review to identify no-cost and low-cost energy-saving opportunities, and a general view of potential capital improvements and also to identify if the energy savings justify level II audit.  

Level II Energy Audit : 

Level II Energy Audit includes a detailed survey and engineering analysis of EEM’s which are identified in the walk-through and potential capital-intensive energy savings opportunities. Level II audits include an in-depth analysis of energy costs, energy usage, and building characteristics and a more refined survey of how energy is used in your building. It also identifies EEM’s which qualify for a III audit for further analysis.

Level III Energy Audit : 

Level III Energy Audit includes a more detailed analysis of Capital-Intensive Modification Audits (sometimes referred to as an “investment grade” audit) and provides solid recommendations and financial analysis for major capital investments. In addition to Level I, and Level II activities, Level III audits include monitoring, data collection, and engineering analysis. 

Our energy auditors work with you to understand your project goals and available budget and help you determine which level of audit you need. For smaller facilities where there is no major capital improvement plan or budget, a Level I audit could yield results that make the cost of the audit worthwhile. 

Utility rebates driven audits:

Utility companies provide various rebates from time to time to help encourage reducing energy consumption, achieve sustainability, reduce the overall carbon footprint and reduce carbon taxes. Please stay connected and subscribe to our newsletter to obtain the latest information on rebate programs which you can take advantage of.

We customise the study based on the rebate program and your needs and help you obtain rebates and implement the EEM’s to realize the savings.

Greenhouse Energy audit:

One of the major expenses for greenhouse producers is energy, and therefore a greenhouse energy audit helps in reducing energy usage costs and thus lowering the operating costs of your greenhouse. 

The audit identifies how current energy is used for operating a greenhouse, including heating systems, cooling systems, lighting, water heating, irrigation, and ventilation and compares the current use to energy-efficient alternatives. A completed energy audit provides data that a greenhouse owner can use to make informed decisions about equipment upgrades.

Additionally, some energy efficiency grant and loan opportunities are available that may require an energy audit as part of the application process. Energy audits completed by Green Globe auditors qualify for this purpose.

Through an energy audit greenhouse growers evaluate their operations’ current energy consumption and identify potentially energy-efficient alternatives. A successful audit requires information from the owner and dialogue with a trained auditor.

The process involves information gathering, the auditor and owner have a meeting and exchange of information, followed by a greenhouse walkthrough. 

Please get in touch with us to see if you qualify for a complimentary walkthrough audit!
