RIBuild is an EU research project that develops guidelines on how to install internal thermal insulation in historic buildings while maintaining their architectural and cultural heritage.

The purpose is to reduce energy consumption in historic buildings in order to meet the EU 2020 climate and energy targets.

RIBuild stands for Robust Internal Thermal Insulation of Historic Buildings.



Significant potential for energy savings in historic buildings


Today, historic buildings make up 30% of the European building stock. Historic buildings account for more than a third of the total energy consumption of buildings in the EU. Therefore it is vital to reduce their energy consumption.


The potential for energy savings in historic buildings is 15-20%. However, installing internal insulation can be a difficult task subject to a certain risk of failure and high costs. Building owners and practitioners in the construction industry need knowledge and guidelines on how to handle internal thermal insulation in historic buildings in an effective and secure way. RIBuild has set out to fill this gap.


The RIBuild project runs until the end of 2019 and will conduct an in-depth investigation on how and under what conditions internal thermal insulation can be employed. Research activities include on-site case studies as well as simulations and laboratory measurements of materials. The RIBuild project will result in comprehensive guidelines on how to install internal thermal insulation in historic buildings.



Guidelines for practitioners


The guidelines on how to install internal insulations in historic buildings aim to help authorities, building owners, consulting engineers, contractors and other professional practitioners within the building sector in the EU. The guidelines will be applicable to historic buildings all over Europe.


The guidelines help both the decision-making for solutions and in the planning phase. A number of guidelines will be developed:

  • Guidelines for determining whether a building is suitable for internal insulation or not
  • Guidelines for a standardised simulation and testing methodology
  • Guidelines with a catalogue of possible solutions depending on the construction type, climate etc.
  • Guidelines for evaluating the energy saving potential and the environment impact



Cross-border research


Ten research institutions and companies from six EU Member States and Switzerland participate in the RIBuild research consortium.

RIBuild has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 637268.
