An overview of how to use temperature and humidity loggers alongside CO2 loggers to help save energy and money.
At a time when energy efficiency is paramount to cutting carbon
emissions, it is important that increasing ventilation rates do not
contribute to greater energy usage and energy loss.
Reports recommend that ventilation rates should be
balanced against the extra energy demands resulting from
increased ventilation. Extra energy, for example, may be required
to heat and/or humidify a space if increased ventilation causes
heat loss or dries out the air. Monitoring temperature,
humidity and CO2 can help to save
energy by informing the use of ventilation only when
necessary and only for an appropriate duration.
CO2 data loggers with alarms are
particularly useful, as these can prompt occupants to ventilate
only when extra ventilation is required. A long-term
understanding of CO2 levels, meanwhile, enables
facilities managers to supply ventilation to indoor spaces at a
rate that is appropriate to the time of day or season.
Temperature and relative humidity data loggers
can be used to assess heat transfer rates and
understand how humidity levels correlate with
ventilation. When compared with CO2
data, building managers can prevent excess heat and
humidity loss by ensuring that ventilation occurs only for the time
it takes to ensure effective replacement of the air.

The report from the Environmental Modelling Group and SPI-B
anticipates that wider uptake of CO2 monitoring,
combined with public health campaigns and appropriate workplace
training, could improve people's awareness of the
importance of indoor air quality. This, in turn, would
lead to improvements in how indoor air quality is managed and how
new buildings and retrofits are designed.
Indoor air quality monitoring with data loggers
is both simple and cost-effective. USB-connection
data loggers are easy to set up and use, and can
be moved between locations and rooms to monitor where necessary.
New data loggers can easily be incorporated into an indoor air
quality monitoring strategy on an ad hoc basis, making the initial
cost of investment flexible to different budgets.
The Tinytag range of
data loggers offers options for monitoring
relative humidity and
carbon dioxide. Using Tinytag data logging
software, data from CO2 data loggers can be overlaid
and compared with data from temperature and relative humidity data
loggers, enabling effective analysis of indoor air quality in
combination with occupant comfort.
Outdoor temperature and relative humidity data loggers are also
available for assessing how the indoor environment responds to
outdoor environmental conditions.
