Overview • City of Cedar Falls Thermal Flyover project • Why? • Background • A few images • How CFU uses hand held Thermal imager • Alone • Attic • Inside Home - at least 60 homes per year • Confirm insulation • Comfort issues for customers
Why Aerial Thermal Imaging? • Have a strong community-based utility and rebates • We wouldn’t do this if we didn’t have a strong presence in our community. This type of project needs community support! • Educate and encourage those “tough” customers who haven’t participated in last 20 years • Homes, businesses, rental properties • Attic insulation is a low-cost, “gateway” measure • If we find that a property needs attic insulation, it usually needs most other energy efficient things too!
Background/Funding • Our essential partners • Local experts: University of Northern Iowa • Iowa Office of Energy Independence • Community groups & utility marketing department • “Cool Congregation “ • “Cool Neighborhood” • Received $187,000+ from State Energy Program: • $53,000 to take aerial imagery of 30 square miles • About $36,000 for labor to process imagery & host on website map • During course of project, 12 jobs funded by it
Aerial Thermal Imaging Process • An airplane equipped with thermal imaging equipment flew at 1000 feet in a series of 54 overlapping passes over the entire City of Cedar Falls. • For best results, the flights took place on two cold and clear nights, with no snow on the ground. • The thermal imager used on the airplane measured the surface temperature of buildings and the ground. • The photos were compiled into a map and CFU customers can search for their property by address.
Why Aerial Thermal Imaging? • Way to make building shell upgrades “sexy” • Which is more visually appealing?
What Do Customers Experience? • The images show an estimate of heat loss and general insulation levels. • Red, yellow and orange indicate heat and that the property may be losing heat through the roof. • Customers are encouraged to contact the utility for additional thermal imaging audits, or diagnosis if needed
