• The Use of Infrared Thermal Imaging in Indoor Environmental Investigations
  Infrared thermal imaging has been increasingly used to identify wet building materials that can be sources of mold growth and degraded indoor environmental quality. However, IR is also an important tool in the evaluation of HVAC (heating, ventilating, and air conditioning) systems, which...
• Available Gas Concentration, Sensors, Probes & Connectors
  An unsatisfactory room air quality of indoor rooms (e.g. in offices) can easily cause tiredness, poor powers of concentration and even diseases to people. Indicator for the room air quality is the concentration of specific gases in air. The most important ones include: ?? Carbon dioxide (CO2...
• Infrared Thermography - the Binding Link to IPD
  assist with equipment linkage, allowing for better quantification of a buildings' Indoor Environmental Quality (IEQ) assessment. Infrared thermography can be considered the "vision" to the "blind" while assessing compromised IEQ issues. This paper will provide a better understanding of regulatory...
• Using Infrared for Residential Energy Surveys
  to insulation and infiltration issues, but to the interactional relationships between the building envelope and the mechanical air distribution parts of the HVAC system as well. If these interactions are not balanced and in harmony, energy efficiency suffers as well as the indoor air quality...
• Energy Certification - Establishing Thermography in the
  of conditioned air to the outside as well as the entry of unconditioned air to the. controlled environment results in energy loss as well as indoor air quality issues. These types of building. "defects" or problems are even harder to detect and control without infrared technology. Thermography can...

• A Paradigm Shift in Gas Monitoring
  disease in coal mining, asbestos and indoor air quality concerns, and recognition of gas hazards in confined spaces. All in all however, air and gas monitoring is only one portion of the daily concerns of a safety manager. From a corporate perspective, gas monitoring is a minor part of the overall...
• Managing Optical Performance - AN117
  . This scale was developed for paints and does not fully correlate with the. appearance of an AG treatment in a display system. AG and AR treatments are not exclusive; some designs use a combination of AG. and AR treatments. In general, AG treatments are more effective at indoor. illumination levels...
• UVC Keeps Out Unwanted Condo Resident: Mold (.pdf)
  , "Th. e UVC Emitters. have improved indoor air quality and system cleanliness at a frac-. tion of the cost of alternative strategies." Th. e installation, which. included 1,240 fan coils, plus the makeup air units that serve the. building, is believed to be the largest of its type. SEARCH FOR SOLUTIONS...
• Optical Enhancement Tutorial
  in kiosks, advertising displays, control towers and aircraft cockpits, to name just a few. In order to improve the situation, several technological developments have been made. The luminance of the display must be increased well above normal levels expected for indoor use. The contrast must be made...
