Contribution to Annex 65 - EASEE Project - Annex 65 Kick-Off Meeting Long-Term Performance of Super-Insulating Materials in Building Components & Systems GRENOBLE – France Contribution to Annex 65 - EASEE Project - 11-12 Sept 2014 Prof. Bruno Daniotti, Rosanna Galliano - POLIMI

Objectives UE Project – 7FP 48 months project (2012-2016) Envelope Approach to improve Sustainability and Energy Efficiency in existing multi-store multi owner residential building Project http://www.easee-project.eu/home http://www.euronews.com/2014/09/08/new-skins-for-leaky-buildings/

Objectives Focus on WP4: Prototypes for thermal inner retrofitting Hygro-thermal properties - characterization tests Installation on the test wall Monitoring & Modeling pre and post-retrofitting

Prototypes for internal retrofitting Design and production at EMPA of 3 different solutions (aerogel based & perlite based)

Characterization tests Lab tests for assessing the hygro-thermal properties Develop functions for aerogel based material 1. Thermal conductivity measurements (dry and moist condition) Lambda value at 50% , 80% and 95% RH 2. Water vapour permeability (dry and wet cup method) At 23°C and 0/50%RH by means of desiccant for dry state At 23°C and 50/93%RH by means of salt solution for wet state 3. Hygroscopic sorption tests (at isotherm condition) Water content at 30%, 50%, 80% and 95% RH 4. Water absorption by total immersion Free water saturation value 5. Water absorption coefficient by partial immersion Aw 24h

Installation on the test wall

Monitoring & Data Collection Indoor and outdoor sensors: T surface, T air, RH surface, RH air, Heat Flux, Solar radiation, Rain, Wind Pre & Post Retrofitting

Modeling pre & post retrofit Heat and Moisture Transfer calculation in transient condition Comparison with data monitoring Performance evaluation: - Transient U-value (pre & post) Moisture content Indoor comfort Long-term prediction about performance decay over time Different weathers & indoor climate Define main aging factors & …DURABILITY… WUFI 5.2, (Wärme und Feuchte instationär - Transient Heat and Moisture), developed by IBP – Fraunhofer Institute for Building Physics
