This 10th webinar was focus on building energy performance calculations for non-residential buildings. At this webinar we demonstrated how the EPB standards enable to deal with various types of buildings and systems, taking in to account different conditions of use (EN 16798-1) and different control strategies, for different climates.

The goal of these example calculations is to demonstrate:

  • the functionality (the calculation works all together on practical cases, available features to describe energy properties of buildings and HVAC installations)
  • the sensitivity (impact of single data or group of data on selected calculation results), and
  • the usability (clear data input; description of practical system configurations, useful results and avoiding unnecessary input complexity)

of individual calculation modules and of the whole building calculation procedure.

The calculations are performed for the most representative building types, technologies and climates.
