General Energy Audit Process
Prior to visiting the building, annual consumption based on fuel, electric, water, and sewer bills is calculated. The resulting data will be analyzed for existing trends and anomalies, and benchmarked to determine the overall efficiency of the building with regards to similar buildings. AEA will provide this detailed assessment to the building owner so that they may not only see what is currently happening in the building, but can also objectively evaluate the savings once energy savings measures have been installed.
Following this assessment, a field crew or auditor will visit the building to verify dimensions and inventory the building’s windows, doors, and light fixtures.
Once this basic inventory of building systems has been created, a team energy engineers will visit the site in order to evaluate the current building systems and assess all relevant capital improvements. The site visit begins with an interview with the key building staff to determine any current issues that the building has, and any specific energy savings measures that the building staff would like to evaluate. The energy engineers will evaluate the building enclosure, heating, air conditioning and ventilation systems, lighting, fans, motors, pumps, process equipment and appliances in the building. Performance and diagnostic testing will be conducted on all building systems to determine the current quality of performance and efficiency. Operations and maintenance procedures will be reviewed and building operating staff interviewed to assess overall building maintenance and staff capacity.
An energy model/building simulation will be developed based on the site survey and any available building drawings. Using the energy model and additional proprietary software analysis tools and calculations, AEA will develop a comprehensive energy efficiency scope of work with projected costs, projected savings, and appropriate payback metrics.
A written report with photographs and illustrations of the building conditions will be presented to the building owner. The report will include a list with general descriptions of recommended energy efficiency measures to reduce energy consumption in the building. Each recommendation will include: installed costs, projected energy savings, demand savings, operation and maintenance and water/sewer savings. An economic analysis will be provided including: payback period, savings to investment ratio, life cycle savings, and ROI.
