Monitoring

Installation

The Installation scheme was realized within the craft for electric installation.

Analysis

There have been very few complaints about the indoor climate.
Automatic regulation of air and temperature function according to expectations.
Energy consumption is monitored on a daily basis.
The total consumption complies with objectives of the project.

Monitored energy consumption during almost two years show that we have reached our goals and that consumption in fact is a little lower than calculated.

The results were a bit surprising. The different air flow regulations had minor effects. The overall impression is that the students experience of air quality and temperature to a large extent is psychological. In many cases there seem to be a link between temperature and air quality: low temperature results in poor air quality judgment even though CO2 value is very good. Likewise, comfortable temperatures often result in a good air quality judgment even if CO2 value is high. Comfort temperature varies among the students. The set temperature of 21 °C is defined as comfortable by some and too cold by others, who need 22 to 23 °Cto be satisfied. Outdoor temperature also has some bearing on the perception of room temperature. Cold weather produces lower indoor temperature results even though actual temperature is fine.
