Energy Audits

Energy Audits

Expert audits, studies and consulting, conducted by Armstrong's trained specialists.

Armstrong will perform a comprehensive, on-site evaluation of your utility system to reveal inefficiencies, identify opportunities for improvement, and uncover the cause of current or potential problems. After analyzing the results, our specialists will determine which intelligent solutions will be most effective in achieving your objectives. Your detailed report will include recommended Energy Conservation Measures (ECMs), schematics, drawings, estimated savings (thermal, water and financial), reductions in emissions, and more.
