Integrale Energietransitie Bestaande Bouw

The Integrale Energietransitie in Bestaande Bouw (Integrated Approaches for the Energy Transition in Existing Buildings) is a multi-year, multi-stakeholder program focused on developing affordable and user-friendly renovation concepts for residential buildings. The program consortium is working on innovative solutions for heat conversion and storage, digitization, industrialization concepts, decision-making frameworks, value chain integration and partnership models.

The project was initiated by the Building and Technology Innovation Centre (BTIC) and is led by TNO. The project consortium is made up of over 125 organizations, including knowledge institutions, construction companies, the technology and design sector, governments, homeowners and residents.

The project is supporting the ambition of the Netherlands to renovate 200,000 homes per year in a manner that reduces greenhouse gas emissions achieves a climate-neutral built environment.

The project will run from 2020-2024.
