  • Mold-MoistureAs part of our moisture evaluation, we look for water intrusion, condensation issues, humidified spaces, and vapor transport through building assemblies.  Through the identification of moisture sources, testing for mold is performed and remediation alternatives are suggested.  Mold is often the source for occupant health concerns and discomfort.

    Moisture and mold can be found in many locations in a building and originates from a number of sources.  It can be detected in the building envelope, under a building (such as a crawlspace or flooring system), in the plumbing / piping, or even in HVAC components, among many other areas. 

  • Air_FlowMany important elements are taken into consideration when evaluating air flow in a building.  Problem areas with issues such as air leakage and unbalanced ventilation are examined, as well as pressure differentials and containment pathways.  In an air flow analysis, the quantity and quality of air flow is tested and recommendations are made regarding possible reuses and better filtration of air.  Cost-effective conservation opportunities for heating and/or cooling technology can assist building owners not just in improved air quality, but also in long-term savings.

  • Building_EnvelopeBuilding envelope commissioning services involve design review of building enclosure systems (walls, roofs, and foundations) to ensure the air tightness of the enclosure is below the prescribed maximum rates. 

    As members of the Building Commissioning Association (BCA), our design review (as part of the building enclosure commissioning services or as an independent review not associated with building commissioning) traces the building enclosure to identify penetrations, changes in components, and the continuity of the air barrier.  

    Our review also includes indications of air sealing.  We observe the installation of air barriers, vapor barriers, and water diversion components (flashing, etc.).  Wall section testing must be completed in order to verify the leakage rate of the wall and roof systems (walls, openings, penetrations, joints, corners, etc).

    Testing includes:

    • Insulation
    • Vapor Retarders
    • Dew Point Analysis
    • Infrared Theromgraphy
    • Blower Door Testing
    • Heat & Moisture Analysis

    Poor Indoor Air Quality (IAQ) can lead to occupant health concerns, increased energy costs from building system failures, and are costly to mitigate or rectify.  Proper IAQ evaluations help building owners learn how to keep their building dry and clean, comfortable, reduce potential contamination sources, properly ventilated and minimize air infiltration, and reduce unplanned air flows. 

    There are times when a building environment leads to legal action.  Turner Building Science & Design, LLC (TBS) has been performing forensic investigations for use in litigation since 1993.  TBS has unparalleled experience and knowledge.  We offer you experience gained through hundreds of forensic investigations.  A few of the services we provide include:
