co2 control for classroom gardens

CO2 Control In School Classrooms AirTest Technologies

CO2 Sensors will automatically regulate fresh air delivery so that overventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...

Lawns Reduce CO2 Levels Garden Myths

It is CO2 in the atmosphere that is the problem for global warming. Plants convert CO2 to other forms of carbon such as wood. When plants die, the carbon in the plant will again be converted back to CO2. Oil is the result of dead plants – a form of carbon. When we use gasoline, which contains a lot of carbon, it gets converted to CO2. The conversion of carbon to CO2 and CO2 to carbon is a ...

Rooftop Gardens: Benefits for Energy Consumption

Rooftop gardens can absorb CO2 from the air and release oxygen in its place, creating a healthier urban environment. Currently, CO2 emissions are the largest contributor to greenhouse gases released by humans. If we installed green roofs, we would be able to reduce this percentage while still conserving energy. A study in Michigan estimated that if every rooftop in Detroit had greenery, these ...
