(Updated Jan. 22, 2021)

The 9^th webinar was organized on Tuesday 19^th January 2021 (12h00-13h30) on "Example calculations with the set of EPB standards – (3) Whole building calculations, from components to overall primary energy".

Following the successful first series of 6 webinars on the Energy Performance of Buildings standards (EN/ISO) supporting the implementation of the EPBD (see the list below), an additional series of 4 webinars has been scheduled on the set up and results of a series of example calculations on buildings and systems using the EPB standards.

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 will be performed for the most representative building types, technologies and climates.

The topics of all seminars can be found on the overview page.

This 9^th 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.

Series of webinars on the EPB standards

A series of webinars on the EPB standards was jointly organized throughout 2020 and early 2021 by BUILD UP in cooperation with EPB Center’s experts under the scope of Service Contract ENER/C3/2017-437/SI2-785.185 “Support the dissemination and roll-out of the set of Energy Performance of Buildings standards developed under EC Mandate M/480” (duration September 2018 - September 2021).
