CO2 Monitoring for LEED Credit |

In both LEED versions, using CO2 monitors as part of an overall IAQ strategy is worth at most 1 credit. In addition, both LEED versions require CO2 sensors to be re-calibrated every 5 years, and for the sensors to be accurate to within 75ppm or 5% of the actual CO2 level, whichever is greater. What is different between LEED v3 and v4?
