Energy experts will <br />conduct a comprehensive review of <br />your building’s energy consumption – <br />even if your building was previously <br />commissioned. Recommissioning <br />studies will identify opportunities to <br />effectively reduce your energy use <br />up to 20 percent. You can earn study <br />and implementation rebates with this <br />option. <br />2) Fast Track Studies. This option is <br />for customers who have completed a <br />recommissioning study on their own, <br />without receiving study funding from us. <br />You can earn implementation rebates* <br />with this option. <br />3) Fast Track Proposal. This option is <br />designed specifically for customers <br />who may not be ready to undertake <br />a comprehensive recommissioning <br />study, yet have identified one or two <br />specific recommissioning energy-saving <br />measures. You can earn implementation <br />rebates* with this option, as well. <br />4) Refrigeration Recommissioning <br />Studies. Supermarkets are the most <br />electricity-intensive type of commercial <br />building – and refrigeration accounts <br />for half of an average store’s electricity <br />use. Refrigeration recommissioning <br />studies identify opportunities to tune <br />up existing refrigeration systems rather <br />than replace them, ensuring more <br />reliable operation, which helps to avoid <br />costly repairs and reduce downtime. <br />You can earn study and implementation <br />rebates with this option. <br />* In order to qualify for Fast Track rebates, your <br />analysis should include energy saving estimates and <br />demonstrate a thorough understanding of the affected <br />equipment’s energy and demand consumption. <br />Find Out if Recommissioning Is <br />Right for You <br />Contact your Xcel Energy account <br />representative, or contact our Business <br />Solutions Center at 1-800-481-4700.

With today’s buildings and <br />systems becoming more complex, <br />the need for commissioning contin- <br />ues to grow. Unfortunately, com- <br />missioning remains an uncommon <br />practice. <br />Recommissioning takes another <br />look at a building that was previ- <br />ously commissioned to ensure it <br />is once again running at optimal <br />performance. <br />Retrocommissioning involves tun- <br />ing up an existing building that was <br />never formally commissioned. Unless <br />you requested commissioning, it’s <br />likely your building’s systems never <br />were properly calibrated for ongoing <br />efficiency. <br />Xcel Energy’s Recommissioning <br />program covers both recommission- <br />ing and retrocommissioning.
