Conventional Ventilation:
• Most of the ventilation system, conventional and even most modern ventilation are designed and work on the basis of worst-case scenario.
• Provide fix rate of air flow irrespective of level of occupancy or air quality (AQ).
• Lead to huge amount of energy and money wastage
• Energy & environmentally inefficient system. Em

Demand Controlled Ventilation (DCV):• Regulate ventilation requirement, fresh supply and exhaust air• Ventilation depends on demand rather than supply• Lesser need to condition the intake-air• Monitor space occupancy• Maintain indoor air quality - IAQ• Meet LEED and ASHRAE standard• Reduce sick building syndrome• Make better, healthier working environment• Energy efficient method E

Why DCV by IAQ, not by CO2 monitoring:• CO2 sensors measure and monitor just CO2 (carbon dioxide)
concentration in the ambient air.• Air quality change by not only CO2 conc., but also volatile
organic compound (VOC).• Eg. In freshly painted room, CO2 sensor will show 350-400ppm
concentration, hence would not trigger ventilation process. But air quality sensor would also monitor VOC compound, so air quality sensor would be reading higher and hence can trigger ventilation process to better the indoor air quality.

What affect air quality:
Air quality is affected by (list not exhaustive):
•Perfume, phenyl mopping•Heating of pc, laptop, printer, electronic products•Breathing of clothes•Carpets•Wall paints, wooden liquor etc•Varnish, leather etc•Body odour, sweat etc•And many more E

Advantages:
• Huge energy (power) saving to the tune of 30-60% (supported by many international papers and analysis)
• Very low payback period (about 3-9 months)• Huge reduction in system operating cost• Looking at Global Warming – Environment
friendly and Qualifies as an essential part of a Green Building

Energy/power saving is directly proportional to fluctuation in human occupancy. More the fluctuation, more power saving.

Other benefits:
• Decrease in sick behavior and human fatigue, hence increase in workforce productivity
• Answer to sick building syndrome• Helps reduction in workforce absenteeism • Improvement in indoor air quality, leading to
increase in mental efficiency• Improve humidity control• Reduction in suffocation, nausea, headache,
asthmatic behavior• Improve child’s mental power and ability

Cost / Benefit Analysis:
• Very low payback period of 3-9 months (supported by many international papers, analysis and commercial application)
• 30-60% energy saving lead to huge operating cost reduction
• Concept and application is eligible for carbon credits, which will further reduce payback period and provide additional income. E
