Periodic Report Summary 2 - MF-RETROFIT (Multifunctional facades of reduced thickness for fast and cost-effective retrofitting)

Project Context and Objectives:
The MF-Retrofit project aims to deal with the numerous requirements of facade panel retrofitting by developing a light-weight, durable, cost effective and high performance panel. Its layered structure allows for separate but also synergistic function regarding high thermal and acoustic insulation, excellent mechanical properties, up to standards flame retardancy and photocatalytic activity. In order to achieve these tasks, a multitude of techniques and technologies need to be combined in research and development level, with a vast array of raw materials employed. individual components have a definite environmental orientation, taking advantage of recycled materials and biomass foams, low energy and low toxicity processes. Finally, project viability and sustainability will be ensured by performing a Life Cycle Analysis in order to optimize individual processes. Hygrothermal behaviour and thermodynamics will also be simulated and modelled to ensure the high performance of the panel.

Project Results:
A formulation for the PU matrix was developed, it consists of a commercial basic formulation with high bio-contend.This formulation was modified and optimized by ICT to further increase the bio-content by the addition of a self-prepared polyol. To fulfill the requirements in regard of flammability different flame inhibitors were tested with Melamine being found as optimum additive. Furthermore, the integration of PCMs was investigated for the anchoring layer. Based on modeling of the thermal behavior, the optimum content was determined and panels were produced in pilot scale containing the self-prepared biopolyl from ICT and PCMs from UAVR.
The durable layer was developed through the alkali activation of fly ash. The processing involves mixing of fly ash with an alkaline activation solution, molding and curing at low temperature. As a result the final product has much lower embodied energy and CO2 footprint compared with conventional structural materials.
The durable and the main insulation layer were integrated in one compact layer in order to facilitate the assemblage of the panel. This procedure includes the casting of the geopolymer on the top of a prefabricated insulation layer. As it was found, the thermal properties and the performance of each individual layer were not affected by the integration process.
The second structural layer consists of a fiber reinforced polymer (FRP) with intumescent layer for fire protection. And finally a photocatalytic paint is applied on the intumescent layer.
All the layers have been integrated to produce the MF-Retrofit panel. The panels are currently undergoing outdoor validation.

Potential Impact:
The project’s advancements are expected to be:
• Customization possibilities: Apart from panel thickness which can be easily tuned, integrated encapsulated nano-PCMs will be tailored along the customer needs regarding temperature of phase change. The integration of the layer materials in the prototype panel will be conducted in "slot" configurations, that will enable customization based on user requirements as well as overarching conditions such as climate and location.
• Easy and fast to install: It is calculated that 10 m2 can be installed in less than 2 hours by 2 workers
• High acoustic and thermal insulation: The three internal layers offer varying degrees of insulation, with an inorganic insulation aeroclay layer providing fire protection.
• Photocatalytic activity offering self cleaning and antimicrobial behavior, virtue of the surface coating. In addition, the surface coating will also contribute to flame retardancy due to nanofillers and/or lightweight materials as heat inhibitors
• Reduction in weight and volume by 40%, as a result of applying polymeric and light-weight materials therefore improving the panel mechanical properties.
