![]() ![]() ![]() Invasive Testing & Analysis – Invasive testing is used to verify findings, determine if proper components were used in construction, verify if proper installation or repair techniques were followed, and to define the extent of a problem. Electronic moisture detection equipment, moisture measurement tools, permeability testing, borescope cameras, hygrometers, plus other equipment and test methods can be used to assess the building. Non-Invasive Testing – This testing is used to support the findings of the visual inspection. Depending on the nature or complexity of the issue, the findings of this inspection can be used to create a detailed plan of action to diagnose and determine causes. Oftentimes a visual inspection is performed in combination with some form of non-invasive testing. Visual Inspection – This is an on-site inspection of the building to assess building conditions. That makes for many, many ways for air and moisture to interact with the building and its components. ![]() These factors include, building usage, zones, stack effect, wind, pressure differentials, and interior and exterior claddings all of which make commercial buildings more complicated and therefore more difficult to properly diagnose than residential property.Īdditional factors contributing to moisture entering the building from the exterior include building age and construction, poor building practices, improperly installed components, shoddy repairs, deferred maintenance, and environmental factors.Ĭombine all these considerations with internal issues such as ground water, condensation, humidity levels, air pressure differentials, and building functions all of which contribute to moisture inside the building envelope. Many factors can influence how moisture moves into and out of commercial buildings. Or when both interior and exterior factors are contributing to a moisture issue? What do you do when the moisture issue is created inside your building? Not all moisture related issues are caused by moisture entering the building from the exterior. The Florida summer can really test a building's envelope. Moisture control is essential in Florida's hot and humid climate especially during the “dog” days of summer when it rains every afternoon. In order to achieve these objectives, all building enclosure systems must include a solid structure, a drainage plane, an air barrier, a thermal barrier, and may include a vapor barrier. The dimensions, performance and compatibility of materials, fabrication process and details, their connections and interactions are the main factors that determine the effectiveness and durability of the building enclosure system.Ĭommon measures of the effectiveness of a building envelope include physical protection from weather and climate (comfort), indoor air quality (hygiene and public health), durability and energy efficiency. The physical components of the envelope include the foundation, roof, walls, doors and windows. Control of air includes air movement through the components of the building envelope (interstitial) itself, as well as into and out of the interior space which affects building insulation greatly. ![]()
