Building Shell with Blower Door infiltration testing and thermal infrared imaging.  Blower door testing now more often done on commercial buildings to help control heating, cooling and dehumidifying costs.

 Blower door configurations include multiple fans for testing large buildings

 






   

 

 

 

 
   
Digital photo of the upper corner of a room with a slanted ceiling and adjoing interior. Common construction practice, especially in older homes.
   
Corresponding infrared picture shows that the area is open to the attic, thus making the bathroom next to it very uncomfortable and contributing to ice dams. Darker shade shows colder temperatures.
   
Infrared digital picture of the same walls after work is completed. Lighter shade confirms that the work was done correctly.






 

Another common location for increased heating and cooling costs are open cavities leading out of the building. This is the number one reason for ice dams /icicles occur.  Our technicians can locate these air leaks so they can be sealed.  It is critical that these be sealed to improve the performance of the building.

Snow melting patterns and ice damming:





  
 
 


  
These photos show snow melting patterns on rooftops, which is evidence of air escaping or poorly insulated ceiling.
In these three cases, heat is escaping out of the house and into the attic, which melts the snow on the roof. The lack of insulation causes high heating costs, as well as ice damming issues.
  





Moisture-related / structural problems:





  
  

This picture (left) shows an improperly installed exhaust vent. The moisture is not being exhausted out of this apartment building, which causes deterioration of the wood as well as mold/mildew problems.  This can also deteriorate the roof sheathing before the shingles need replacing.

 


  

Condensation on the windows is an indication of high moisture and lack of proper ventilation in a building.  This can eventually lead to the deterioration of the windows, building or mold problems.

  
 


  
  

Improper water drainage around the foundation (left) can lead to moisture problems in the inside walls of lower levels and basements, and potential for mold growth on the basement walls or floor.






Safety and air quality:





   

Rusted flue pipes and other leaky piping can cause safety problems such as potential carbon monoxide poisoning. We check appliances for carbon monoxide and proper draft to protect the occupants of the building.
