Energy Audits

EES energy audits are led by our Certified Energy Managers (CEM) with the qualifications necessary to deliver a high quality energy assessment that is meant to provide our customers with the information necessary to invest in the critical infrastructure systems and processes that delivers the greatest payback. 

It is very common to have under performing or oversized infrastructure support systems such as compressed air or refrigeration systems contribute to poor system efficiency or poor process performance.

Emergent Energy Solutions - Energy Audits

Our energy audits will deliver a comprehensive assessment of current system operations with recommendations for remediation.  We follow an engineering regiment that follows a three step partnership approach.

  1. Understand our customer’s objectives and challenges
  2. Assess the current systems
  3. Provide list of Energy Conservation Measures (ECMs)
  4. Depending on the measure identified, we can also help with the implementation of the ECMs. Please visit our turnkey solutions to better understand how we can help with your energy projects. 

    Our systems expertise includes a mix of commercial and industrial processes. Our differentiated approach includes the process of incorporating available state, utility, and grid incentives to help buy down the cost of developed projects. 

    1. Utility sub-metering of critical building energy resources, which includes: cooling & heating BTU’s, Steam, Electrical, Water, Gas, Fuel Oil. These sources can provide significant information on system efficiency and performance. One of the most effective and commonly used metering systems we have put in place includes the measurement of chiller system efficiency through the installation & integration of electric and BTU meters on central plant chillers. These installations deliver significant visibility into chiller plant efficiency on an ongoing basis as well as providing central plant operators with visibility into continuous and live cooling demand data for system optimization and ultimately better management of their chiller plant.
    1. Pumps, Blowers and Fan Systems - The oversizing of these systems has been a common practice. As these support systems are typically sized for worst case conditions where a building or a process might need maximum air or liquid flow, these systems operate inefficiently 95% of the time. The proper sequencing and installation of VSDs to throttle their operations to meet the demand for cooing or heating will contribute to a more efficient and reliable system. Proper system control and sizing ultimately contributes to less START / STOP's, more continuous and balanced operations and improve building comfort from reductions in system cycling. 
    2. Power Factor Correction - Extremely common in high volume induction motor systems that have oversized motors. Depending on the utility company, poor power factor can be penalized on a monthly basis if the customer is being billed based on KVA rather than KW. Having poor power factor can also reduce the site's overall system capacity. 
    3. Waste Heat and Cooling Recovery - Manufacturing processes as the term suggests includes value added processing of raw materials. These processes typically include the application of heat or cooling to these raw materials. Whenever heat or cooling is applied, there exists the potential for energy waste and possible recovery of these BTUs from the process. The feasibility of BTU recovery rests within the cost to value assessment associated with the quality of the heat or cooling available for recovery. 
    4. Control Systems for efficiency gains through integration - Within the past 20 years, mechanical system manufacturers have had to shift their product strategies from primarily designing and constructing hardware to producing more intelligent equipment that can be integrated and controlled as a component of an overall process. During this rapidly changing period, these manufacturers were forced to standardize on communications protocols, level of integration they would individually deliver as well as whether they would be the integrator or the integrated component within a specific process. As one might imagine, this rapid pace of change brings much confusion and inefficiencies. EES will assess a system's operations and identify possible benefits from better system integration and sequencing. 
    5. Compressed Air System Optimization - Compressed air systems have become an essential component of the manufacturing process. It provides rapid and high energy delivery to actuating devices and vacuum Venturi devices. The opportunity for compressed air system optimization comes from the common practice of how these systems are designed and installed. Typically a facility starts small with 1 compressor. As sales grow for these manufactured products, additional compressors are added. A simple system that started with 1 or 2 compressors has now tripled in size. When a compressed air system has more than 3 compressors, it can benefit from the implementation of a central Smart Sequencer to control system START / STOPs and the loading of the compressors. The scale of the opportunity depends on the variability of demand, compressor sizing and the rate of air demand fluctuation. 
    6. Process Load for COGS Determination vs. Building; Energy Management System for Energy Segregation - As a subset of Utility Sub-Metering, some of our customers have looked to understand the energy use mix to determine the true COST OF GOOD SOLD (COGS) to allocate their overhead energy and their process specific energy use. 
    7. Variable Speed Integration with Controls - Well deployed variable speed controls helps to balance the supply and demand for a resource. Our assessment will aim to provide a better understanding of the opportunities that exists within these motor driven systems. 
    8. Lighting - LED Lighting has been a stable measure within the energy efficiency space for the past 10 years. As LED technology has continued to evolve and deliver greater lumen vs. wattage efficiency, project deployments have continued to deliver great savings and highly desirable savings. 

    If there are any systems that you need help with that does not fit into the various system categories identified above, please reach out to us and provide further details regarding your specific process for further evaluation.
