Energy Analysis / Audits

Energy Analysis, Audits, and Investigation

The goal of any energy audit is to identify and evaluate opportunities to reduce operating costs through energy conservation and planning.  A proper energy analysis and audit will examine not only your facility's historic utility data and cost, but also your systems, components, and controls to determine energy consumption and use.

At Grand Valley Automation, we offer a series of energy audits that will effectively analyze, inspect, and measure energy use and consumption across mechanical, electrical, and building envelope.

Preliminary Energy Use Analysis

Basic energy use analysis is performed by collecting and analyzing historic utility data and cost. Once data has been collected and analyzed, Grand Valley Automation Engineers can identify areas for improvement based on benchmarks for similar entities.

Level I – Walk-Through Analysis

A Level I audit includes the preliminary analysis, as well as an on-site survey of the building. Grand Valley Automation Engineers will conduct the on-site survey, record observations and analyze data to identify and provide low-cost or no-cost improvement measures. We can also provide potential capital improvements and budget recommendations for implementing the suggested energy improvement initiatives.

Level II – Energy Survey and Analysis

A Level II audit includes the preliminary and Level I audit, but also provides a more detailed building survey and energy analysis. A breakdown of the energy use within the building is provided, as well as a report detailing the capital investments required and potential savings from the investments. A Level II audit will also outline changes to operation and maintenance programs to ensure successful implementation of outline energy improvement initiatives.

Level III – Detailed Analysis of Capital-Intensive Modifications

Level III auditing includes all prior levels of ASHRAE audits and focuses on potential capital-intensive projects identified during the Level II analysis, and involves more detailed field data gathering, as well as a more rigorous engineering analysis. It provides detailed project cost and savings calculations with a high level of confidence sufficient for major capital investment decisions.

Why Perform an Energy Audit?

Performing a facility energy audit will form the basis for setting a realistic long-term sustainable energy plan. Periodic energy audits are an ideal way to improve your facility's energy efficiency and a vital component of any facility energy management program.
