Replacing inefficient equipment provides both energy and maintenance / repair cost savings.
An important part of performing an energy audit is verifying that equipment and controls operate correctly.
An Energy Audit is a comprehensive evaluation and analysis of a building’s current energy use, and identifies alternatives for reducing energy costs without impacting the current level of comfort or productivity within the facility. The number one goal of an energy audit is to maintain the proper level of the indoor environment (comfort, temperature, humidity, ventilation, production rate, etc.). The number two goal is to achieve the first goal at the lowest possible cost for energy. The quality of the indoor environment should not be sacrificed in an attempt to reduce energy costs.
Energy audits should not be confused with Existing Building Commissioning (EBCx). The main difference between energy audits and EBCx is the Current Facility Requirements (CFR). With EBCx, the CFR drives the project by identifying what the current needs of the facility are, which may be drastically different than what the original needs and design were when the facility was constructed. With energy audits, reducing energy consumption and costs drives the project. If a facility has wide-spread comfort complaints, or serious Indoor Air Quality (IAQ) issues, than EBCx should be the service considered in lieu of an energy audit.
Results from energy audits provide insight for building owners and also identify the most economical and energy-saving opportunities. Audits alone do not decrease energy usage; energy-saving strategies must actually be applied in order to see results. However, the implementation of these cost-effective opportunities can result in a payback period typically ranging from six months to four years, depending on many factors such as energy costs, hours of operation, estimated savings and implementation costs. Any existing building is a candidate for an energy audit, but especially those that consume excessive energy, are considering building upgrades, or have never before been audited.
EBCx Services has a broad range of experience performing Energy Assessments/Audits (ASHRAE Level 1, 2, 3) and targeted energy assessments of complex HVAC&R systems. We are experienced in facilities ranging from military bases, prisons, office buildings, healthcare, k-12 schools, universities, pharmaceutical manufacturing facilities, industrial process plants and aviation.
Benefits of an Energy Audit:
ASHRAE has developed and organized different levels of energy audits to provide the industry with a range of choices when a building owner or facility manager is deciding to have an energy audit performed at their facility. As a result, the levels of effort have been organized into the following categories:
Below is a brief overview of each type of energy audit:
Preliminary Energy-Use Analysis (PEA)
Level 3 - also known as an Investment Grade Audit (IGA)
EBCx Services understands how to effectively perform energy audits in a cost effective manner for our clients. If you are interested in reducing energy costs at you facility, please contact us for additional information.
Replacement of existing equipment (retrofits) must be planned carefully to determine both estimated energy savings and construction costs.
EBCx Services holds the following certifications through the Association of Energy Engineers (AEE):
Building Automation Systems (BAS) provides significant energy savings with attractive paybacks. Often the only costs are minor programming and set-point changes.
