Pressure Boundary Testing
Most existing buildings have substantial unwanted bypasses.  Minimizing the air leakage is integral to high performing buildings. 

Dynamic pressure boundary testing is of special interest to Degree Days.  We have conducted countless diagnostic tests across the Midwest analyzing the effectiveness of building enclosure system of both multifamily residential and large commercial buildings through various means.  No building is too big or too small, we test them all!   

We complete diagnostic testing and identify the locations of defective building enclosures. Providing full building forensics for minimum heat loss and optimum moisture control.  

We provide a detailed analysis of how and where a buildings pressure boundary is defective and where it can be improved.  To be effective the "shell" or "skin" of your building needs to function like a warm sweater keeping outside temperatures out while acting as a wind breaker to stop unwanted drafts.  Done properly this not only saves energy but will address an often times worse issue of moisture management. 

From diagnostic testing, plan review, to onsite mentoring and preparing scope of work documents we have the experience to provide you with the means to create a healthier, more durable, and energy efficient building.   

As the mantra goes in the building performance industry, "Build tight and ventilate right."

Notice the cold outside air being brought in through the pressure test.  

Outside temperatures were 38°
"Why test and seal air barrier problems, I thought fresh air was good?"

"Buildings need to breath, right?"     

Wrong...the building and its occupants need proper ventilation and good indoor air quality.  

If your building is breathing you may want to call and exorcist!

By establishing a proper air barrier for your building

  • Reduce building enclosure moisture problems
  • Improve indoor air quality
  • Reduce heating and cooling costs
  • Reduce increase of greenhouse gases
  • Results in more sustainable and durable buildings

The US Department of Energy indicated up to 40% of the heating and cooling energy of a building is due to uncontrolled air leakage.

Many Agencies of the US Government require an air barrier system on federally funded building projects.

Several states now include air barrier requirements in their building codes.

Not convinced YET?!?  Take a look at this article from one of the smart guys, John Straube.
