Recording webinar | #EPBstandards calculations (III)

This 9th webinar focused on whole building energy performance calculations for residential buildings. At this webinar we demonstrated how the EPB standards enable to identify the impact of building and system design (insulated / non-insulated, system technology choice, renewables inclusion), outdoor climate (cold to hot) and assumed use patterns (such as occupancy and comfort schedules on the overall energy performance. We will also demonstrate how (national) choices for partial and overall EPB numerical indicators can effectively control the energy performance and set reliable minimum energy performance requirements.

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.
