Room versus Outside Temperature

This Diagram comes from the standard SIA 180:2014 [1, p. 24-25]. It is mentioned in the planning context as part of the proof of summer room temperatures.

• The indoor temperature, which is perceived as comfortable, tends to be higher, even if the outdoor temperature is higher. This shift saves a lot of energy.
• The x-axis shows the moving average value of the outside air temperature over the last 48 hours. The y-axis the “perceived” room temperature.
• There are three limits
  • Top line: Maximum limit for rooms with natural ventilation, while they are neither heated nor cooled
  • Center line: Maximum limit rooms while they are heated, cooled or mechanically ventilated
  • Bottom line: Minimal allowed temperature (same line for both maximum lines)
• Tooltip: Place the mouse pointer over a datapoint to get more information of a specific measurement.

Settings

Basic

Flat and Room

• Selection of flat resp. room which should get analyzed.
• According to the building hierarchy all flats and rooms get listet which have a datapoint of type “tempRoom” or “humRoom”.

Time Range

• The date left is automatically the oldest timestamp and on the right side the newest.
• Narrow the time range to make comparisons.

Visible Seasons

• The points are colored according to the season.
• With the checkboxes the measurements of a season can be shown and hidden individually.

Extended

• To access the extended settings, the plus symbol in the upper right corner of the title bar must be pressed.
• Per default the extended settings tab is collapsed.
  
  
  
  

Temperature Outside Air

• Selection of the outdoor temperature sensor if more than one is configured under Settings -> Data Points.
