EASEE aims at developing a tool-kit for energy efficient envelope retrofitting of existing multi-storey and multi-owner buildings which combines novel design and assessment strategies, modular prefabricated elements, advanced insulating materials and new scaffolding-free installation approaches, to reduce energy demand, minimising the impact on occupants while preserving the façade original appearance. Particularly, the project will target residential buildings with cavity walls built before 70’s. These buildings require façade retrofitting for technical reasons or improvements in the insulation and energy efficiency to reduce the energy demand, while the conservation of the building appearance is necessary. EASEE will focus on the 3 main components of the envelope that influence the energy performance of multi-storey building, namely the outer façade, the cavity walls and the interior envelope, by developing innovative and easy to implement solutions. A new range of specific solutions will be developed within the project, that will be combined according to the characteristics of the building to be retrofitted as well as to other non technical parameters as for example cost and location of the building, also within the district.
The proposed approach will allow for an overall retrofitting cost over the whole life cycle and for a total cost of ownership up to 120 Euro/m2 allowing a return on investment below 7 years. EASEE will reduce overall retrofitting duration and optimise the worksite in general with direct benefits for the workers and the occupants, while creating new business opportunities worth 4 BEuro in energy efficient retrofitting of existing buildings by the 5th year after project completion, mobilising new cooperation schemes between Les and local SMEs through licensing mechanisms. This is fully in line with the expected impact in the call and with the overall goal of the EeB PPP under the recovery plan.
Task 4.3: Design and prototyping of smart retrofitting solution for the interior (POLIMI)
Starting from the materials characterized and improved during Tasks 4.1 and 4.2, different smart retrofitting solutions will be designed and prototyped at lab scale in this task. Three climatic conditions (e.g. cold, moderate and hot regions) will be taken into account in defining the final target performances. In the design, the following approaches have to be investigated:
1. MULTIFUNCTIONAL strategy: a new kind of textile material, obtained through the functionalization of a textile substrate already available into the market; to create a lightweight and efficient inner cladding system in which a textile core works properly as main structural support, where a specific set of other functional layers could be easily integrated to optimize the foreseen performances
2. MULTILAYERED strategy: Combination of separate functional materials, including advanced textiles (with improved mechanical performances) and mineral, organic and/or inorganic additive/coatings to increase the energy efficiency performances. Working with a multilayered building optimize the efficiency of the whole cladding system, adding or removing singular layer/material in relation to different requirements allowing the minimum employ of material
Lab scale prototypes of the designed solutions will be realised in this Task for further testing and characterization.
Task 4.4: Performance evaluation (POLIMI)
This task will be dedicated to the testing of the developed lab scale prototypes with a specific focus on energy saving requirements (thermal insulation, air permeability, etc) and on durability requirements and test methods for Service Life prediction. The different technical solutions will be evaluated and compared also from the environmental and economic sustainability through Life Cycle Assessment (LCA) and Life Cycle Costing (LCC). Great importance will be done to the characterization of critical points as joints, thermal bridges, openings etc. Guidelines for choosing inner solutions for specific retrofit design conditions (climatic zone, specific regional requirements, specific technologies to be retrofitted, etc.) will be provided top WP5, to be integrated into the retrofitting planner.
