How a common language will foster non-residential building renovation – ALDREN project

Webinar in cooperation with the H2020 ENERFUND project

Date: Wednesday 13 June

Time: 10:30-12:00 (CET)

Tool: WebEx webinar

Organizer: REHVA / Contact person: Tiziana Buso




Non-residential building renovation is a complex topic involving different actors such as asset managers, building professionals, manufacturers, public administrations and, of course, building occupiers. Speaking a common language, understandable by all of these actors, is a fundamental step towards the effective and large-scale deployment of renovation plans. This is indeed the aim of the ALDREN project.

This webinar will provide you with an overview of a European Voluntary Certification Scheme (EVCS), conceived as a tool for a harmonised energy rating of the non-residential building stock. The EVCS is the backbone of the ALDREN project, that will further develop the Scheme by including:

  • energy performance verification by measurements
  • Indoor Environmental Quality criteria

The webinar will suggest ALDREN’s strategy to tackle these challenges and turn them into meaningful indicators. An additional goal of ALDREN is to include these concepts in a Building Renovation Passport for non-residential buildings. In this webinar, ALDREN experts will illustrate how this proposal can fit into the new EU policy framework and how it can relate with ongoing initiatives and existing database. Among these sister initiatives, the webinar will bring up the ENERFUND experience, that shines a light on deep renovation opportunities through map visualizations.
