Building Pressure Analysis

When the air inside a building is under negative pressure relative to the outside air, many indoor environmental problems can develop or worsen, especially in a hot/humid climate. Affected areas can range from localized areas of building cavities (in exterior walls or ceilings) to excessive humidity throughout the building affecting all materials and occupants. Excessive negative pressure is often related to HVAC system design, installation or maintenance problems. Indoor Environmental Technologies' specialized equipment and experience allow us to locate the source of building pressure issues and develop recommendations for correcting them.


HVAC Systems

In a hot/humid climate, like that of Florida, it is critical that your HVAC system properly controls humidity and temperature. Excessive humidity can lead to mold growth, deterioration of building materials, contamination of personal contents and many other Indoor Air Quality concerns. HVAC system problems can be related to over-sizing of the system, leakage or poor design of duct systems, inadequate maintenance, excessive humidity in attics or crawlspaces, etc. Indoor Environmental Technologies work with HVAC engineers and contractors to solve HVAC concerns, as well as to correct any building issues that may have developed.


Moisture and Humidity Monitoring

To spot trends that are useful in diagnosing building problems, Indoor Environmental Technologies has developed methods of monitoring building humidity and material moisture content. This moisture monitoring can be accomplished over a two to four-week period or on a permanent basis. Permanent monitoring allows those responsible for building maintenance to be notified immediately and automatically by email when moisture problems begin to develop in a specific location— before they cause serious problems. This type of early warning system has proven capable of saving tens of thousands of dollars.
