Integration of renewable energy systems at the building scale is a crucial step towards achieving climate neutrality. The newly formed Building Integrated Energy Cluster (BIE) has joined forces towards this objective.

The current European energy system heavily relies on fossil fuels, contributing to a staggering 80% of the European Union's greenhouse gas emissions. In response to this challenge, BIE has been developing innovative solutions to integrate more efficient renewable energy systems at the building scale. The cluster aims to accelerate the decarbonization of the heating and cooling sector through utilization of renewable technologies thus paving the way towards achieving climate neutrality by 2050.

The BIE is formed by two EU-funded projects, IDEAS and RES4BUILD. Supported by the European Commission's Horizon Results Booster initiative, the two projects have joined forces to disseminate their key results towards their joint stakeholders. 

Among the main innovations developed by the Cluster members, there are a set of comprehensive technologies and systems including solar CPC with phase change materials, multi-source heat pumps, smart control systems, PV/T collectors. These allow for an increase in the overall performance of building systems, leading to a reduction in costs for the end user and consumers in the long term.

The technologies developed by the Cluster aim not only to decarbonize the building sector and the energy industry but also to increase the competitivity of European companies, with a clear focus on end user needs and requirements.

This European Union Sustainable Energy Week (EUSEW), BIE is hosting a social media campaign to showcase the newly created cluster and the innovative solutions that are being developed.
