Brady Infrared has been very busy the past year in the infrared building science and roofing industry.   To begin, Scott Eves has joined our infrared building science team.  Scott is a Level-III Certified Infrared Thermographer and LEED AP with a background in HVAC test and balancing of commercial buildings. Over a short period of time, Scott has elevated Brady Infrared to a new level in building thermography by adding technical savvy to solve complex building moisture intrusion problems in warm humid climates.   This the past year, Brady Infrared has taken their building science expertise into the aerospace industry, military medical centers and universities in South Florida.  All of these projects presented a multitude of complex issues related to structural deficiencies and water intrusion.   Most of these projects involve water spray testing, verification of anomalies using non-destructive techniques and in some cases worked with other professionals for destructive verification.

Take a look at some thermal and visual images we have collected on a small sampling of work performed so far in 2013.

Thermal image of a commercial office building that suffers from water intrusion around window frames. Orange areas around window frames show escaping warm air; places where water has been entering building. To achieve the results of this project, the HVAC system was adjusted to create a positive pressure during a winter evening.

Jim Brady, President of Brady Infrared, using a TRAMEX RWS moisture meter to confirm a thermal anomaly detected on a sprayed polyurethane roof system. This roof inspection was conducted during an overcast winter day as the roof slowly warmed up. The inspected took 5 hours to conduct on over 100,000 square feet of roof area.
