My First Audit
Jackie Zusi-Russell, Program Assitant
After working for EnergyFit Nevada for a year, I still didn’t have a full understanding of all the work that goes in to the entire process. Having the opportunity to go on on site for both an assessment and test out helped me understand and put all the pieces together for what goes in to our program. At first I was extremely confused, the auditor pulled out this giant door/tarp and fan like contraption I later found out was a blower door. The blower door depressurizes the home to test for any air leakage in the home. The amount of air leakage is based on how much air from the fan is needed to depressurize the home. After the blower door test was done, the auditor pulled out another tool that looked like it was a top secret spy device. To my disappointment, it was not a top secret spy device, but merely an infrared camera. The infrared camera is used to scan walls, doors and windows to find any cracks, lack of insulation or poor sealing. The infrared camera has a small screen on the front, similar to how an x-ray would look, but in color, red, orange or yellow means an area is hot whereas blues and purples indicates cold. Areas with red, orange or yellow mean that there is either poor sealing, lack of insulation or a giant hole (like when scanning a window). In addition to testing for air leakage and insulation, there are also safety issues when assessing a home. If the home has any gas appliances a combustion appliance zone (CAZ) test must be performed. A monoxor is used to test for any leakage and CO levels in the home. CAZ testing is one of the more important tests because of the health and safety repercussions if anything out of the ordinary is found. Being able to go on site and watch our partners in action gave me a greater understanding of our process as an organization and helped me grasp more than just the paperwork side of the process.
