Tinytag carbon dioxide data loggers are being used by a leading Danish environmental monitoring company to help ensure optimum conditions and energy efficiency are maintained in workplaces and schools. ArbejdsmiljoeCentret (‘works health centre’) are authorized consultants who evaluate factors such as indoor climate, ventilation, noise levels and other aspects of the work environment.

Data loggers in the Tinytag range monitor various environmental conditions including temperature, humidity, carbon dioxide and single or three phase power usage in a wide range of premises. They are compact, accurate and easy to use. Data gathering and analysis of results will help identify areas where steps can be taken to reduce energy consumption, maximise cost savings and ensure the comfort and wellbeing of those inside. Recorded data is downloaded to a PC via a USB cable and viewed with easy to use Tinytag Explorer software.

Part of ArbejdsmiljoeCentret’s remit is to monitor CO2 levels.  Analysis of data from CO2 loggers will help maintain optimum air quality, preventing a CO2 build-up which can cause reduced concentration levels in occupants and in some cases can lead to health problems. In rooms that do not produce their own carbon dioxide, the amount of CO2 in the air will be a product of the people in the room and how long they have been there. The carbon dioxide concentration remains stable if there is consistent ventilation in the room. The amount of CO2 is therefore a key indicator for whether the ventilation is sufficient or not. The carbon dioxide concentration can vary from about 350ppm outside, to 5000ppm in rooms with no ventilation. 

The Labour Inspectorate in Denmark recommends an upper limit of 1000ppm and 1200ppm for school classrooms. Calculations establish the concentration of carbon dioxide in a room, compared to the number of people versus space. The measurements are taken with people in the room, but without venting the room beforehand. The loggers are small, discreet and wall mountable – the latter being advantageous as in the company’ experience, if they are not fixed to a wall they tend to get removed or (particularly in schools) thrown around!

The recorded data is used to document the indoor environment. If concentrations are acceptable they are reported as such. If the measurements are on the acceptable limit, then a recommendation is made on how to improve the ventilation/general work environment. If the results are poor, then a recommendation is given to install mechanical ventilation which in most cases is then acted upon.

Peter Klausch, an Engineer and Freelance Consultant at ArbejdsmiljoeCentret comments, “We chose the Tinytags as they are simple to use, extremely robust and reliable. Understanding the recorded data is very easy, and the Tinytag Explorer software is very user-friendly.”
