Building Science

  • Mold-MoistureMoisture 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.  As 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 / discomfort.

  • 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
  • Indoor_Air_QualityPoor Indoor Air Quality (IAQ) conditions can lead to many issues in occupied buildings, such as occupant health concerns, increased energy costs due to building system failures, and the potential mitigation to rectify those problems.  Through proper IAQ evaluations, building owners can learn how to keep their building dry and clean, provide thermal comfort, reduce potential sources, provide ventilation, and reduce unplanned air flows.

    Unfortunately, there are times when a building environment may lead to legal action.  Under the direction of William A. Turner, M.S., P.E., Turner Building Science & Design, LLC (TBS) has been performing forensic investigations for use in litigation since 1993.  In terms of experience and knowledge, TBS is virtually unparalleled.  We come to you with the experience gained through hundreds of building investigations.
