TVOC measurement for LEED/green building evaluation

Total Volatile Organic Compounds (TVOC) may be evaluated when building designers/managers are pursuing the Leadership in Energy and Environmental Design Green Building Rating System for New Construction (LEED-NC) EQ Credit 3.2. The latest LEED-NC guidance document specifies that the maximum allowed concentration of TVOC measured in a building (post construction, pre-occupancy) is 500 µg/m3; the ...

Feasibility Study of an Express Assessment Protocol for the Indoor Air Quality of Air-conditioned Offices

It is costly to sample all major toxic pollutants in community air. Sampling should be conducted based on an assessment strategy and monitoring planning. Assessment methods that rely on monitoring some representative pollutants have been proposed variously at different times. In Hong Kong, the Environmental Protection Department (HKEPD) launched an Indoor Air Quality (IAQ) certification scheme to ...

Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

Why is a carbon dioxide monitor a good investment?

The easiest way to check if your house is encapsulating gases is to monitor the carbon dioxide (CO2) levels. This one gas is used as a marker for air quality, is the easiest to monitor, and provides a more accurate air quality reading. It is a good trend indicator because it changes in measurable amounts as the air quality gets worse. All other gasses in the house follow the same trend as the ...

What is an `IAQ Profile`?

The 'IAQ Profile' is a visual presentation of indoor air quality. PPM Technology's range of IAQ Monitors enable continuous monitoring of Indoor Air Quality; this precisely describes changes in concentration levels of selected air quality parameters over a period of time. The IAQ Profile provides the knowledgebase and database for improving indoor air quality efficiently and ...

`Green Buildings` can create problems with IAQ

The recent trend towards energy conservation measures have in some cases led to airtight building construction that can often create problems with Indoor Air Quality (IAQ). Some 'green buildings' (also known as ‘green construction’ and ‘sustainable buildings’) have ignored the issue of IAQ in pursuit of energy saving measures. Ventilation systems are set to minimize the ...
