The CDD 300 CO2 data logger measures and analyzes carbon dioxide levels inside a commercial building. The tool allows energy auditors to evaluate some of the major costs directly related to HVAC equipment in office buildings, shopping centers, hospitals, restaurants, malls, and airports. The data logger also helps energy auditors determine how CO2 levels fluctuate throughout a building as an indicator of occupancy patterns. It is then possible for them to determine whether the building is overventilating according to ASHRAE 2007 Standard 62.1 and thus a reduction in energy consumption may be possible by applying demand control ventilation.
