On site diagnostic monitoring, typically using the building management system (BMS), is leveraged to trouble shoot performance issues and to propose remedial actions.<\/p>\n\n\n\n<h2 class=\"has-text-color wp-block-heading\" style=\"color:#182d3f\">The Importance of Recommissioning<\/h2>\n\n\n\n<p>Over time, with changes in occupancy patterns, space usage and adjustments to equipment controls logic, a building may operate with reduced energy efficiency and with diminished occupant comfort.<\/p>\n\n\n\n<p>Just as a vehicle requires servicing once it reaches a certain mileage, so a building requires recommissioning at intermittent points in its lifecycle (typically every five years).<\/p>\n\n\n\n<p>The RCx process benefits the building owner &amp; occupants through:<\/p>\n\n\n\n<ul><li><strong>Improved energy efficiency and reduced operating costs<\/strong><\/li><li><strong>Supporting a robust operation and maintenance strategy, by identifying failed (or failing) equipment<\/strong><\/li><li><strong>Documentation of occupant comfort issues, and revisions to equipment operation to alleviate these issues<\/strong><\/li><\/ul>\n\n\n\n<p>The RCx process ensures that building staff have the knowledge and documentation needed to operate and maintain the building to the highest standards.<\/p>\n\n\n\n<h2 class=\"has-text-color wp-block-heading\" style=\"color:#182d3f\">The Process<\/h2>\n\n\n\n<p>Natural Resources Canada have developed a <a href=\"https:\/\/www.nrcan.gc.ca\/energy-efficiency\/energy-efficiency-buildings\/energy-efficiency-existing-build\/recommissioning-existing-buildings\/20705\">Recommissioning Guide<\/a>, which identifies a roadmap for the recommissioning process:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"561\" height=\"713\" src=\"https:\/\/impacteng.ca\/wp-content\/uploads\/2020\/06\/1.png\" alt=\"\" class=\"wp-image-7130\" srcset=\"https:\/\/impacteng.ca\/wp-content\/uploads\/2020\/06\/1.png 561w, https:\/\/impacteng.ca\/wp-content\/uploads\/2020\/06\/1-236x300.png 236w\" sizes=\"(max-width: 561px) 100vw, 561px\" \/><\/figure>\n\n\n\n<h2 class=\"has-text-color wp-block-heading\" style=\"color:#182d3f\">Impact Engineering Case Study<\/h2>\n\n\n\n<p>Check out the recent Impact Engineering <a href=\"https:\/\/impacteng.ca\/news\/sunset-towers-how-recommissioning-leads-to-large-energy-savings\/\">Case Study<\/a> which profiled our Sunset Towers Project.
