 ==== Cooling outside working hours ====
-Increase of electrical energy use during summer is usually accepted in case of office buildings during summer. Carpet plots are perfect tool for quick evaluation of cooling regimes. Next plot is an example of a wrong cooling regime setting. There is an increase of energy consumption during summer, as expected. However, one can observer increase also after opening hours (after 4 pm).

 ==== CO2 concentration ====
-Evaluation of CO2 by means of carpet plot can also provide quick overview. Data from IoT indoor air quality sensor are evaluated in the next example. There is increase of CO2 concentration during opening hours. Overal CO2 concentrations are ok but slow decrease of CO2 concentrations during evening and night reveals absence of ventilation.

 ==== AHU pressure difference ====
-HVAC appliance operation can be investigated by means of carpet plots as well. Bellow is a carpet plot (horizontal axis: day, vertical axis: hour of day) of AHU pressure difference. It shows regular regime with some irregularities at the end of shown interval. Note that these irregularities cannot be easily found using a classical line chart.
