Why choose REM?
There are two established and linked options when it comes to assessing the energy performance and a building’s carbon footprint: Benchmarking and Full Energy Audits.
Benchmarking
This process enables technical specialists and facilities managers to compare their existing building usage to “typical” and / or “good practice” case studies of exisitng premesis and provides a comparator towards which the concerned party can work to achieve parity.
Full Energy Audit
Level I – Walk-through audit: Preliminary analysis made to assess building energy efficiency to identify simple and low-cost improvements but also a list of Energy Conservation Measures (ECMs), or Energy Conservation Opportunities (ECOs) to orient the future detailed audit. This inspection is based on visual verifications, study of installed equipment and operating data and detailed analysis of recorded energy consumption collected during the benchmarking phase.
Level II – Detailed/General energy audit: Based on the results of the pre-audit, this type of energy audit consists in energy use survey in order to provide a comprehensive analysis of the studied installation, a more detailed analysis of the facility, a breakdown of the energy use and a first quantitative evaluation of the ECOs/ECMs selected to correct the defects or improve the existing installation. This level of analysis can involve advanced on-site measurements and sophisticated computer based simulation tools to evaluate precisely the selected energy retrofits.
Level III – Investment-Grade audit: Detailed Analysis of Capital-Intensive Modifications focusing on potential costly ECOs requiring rigorous engineering study.
REM can provide many of the same results as a Full Energy Audit in a fraction of the time and fraction of the cost and therefore sits between Benchmarking and a Full Energy Audit. The extent and outputs of a REM exercise can be tailored to each project and the scope of investment required can vary considerably.
