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
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.
