Optimal design of multi-functional ventilated facades


A Multi-Functional Ventilated Facade (MFVF) is an assembly of modules, of about I to 3 meters width and one or two storeys high, with two layers of different materials separated by a vertical air channel. They can be uniform but they usually have different zones, like a transparent zone and an opaque zone. They are pre-fabricated and then assembled in the same building.
l-Goal of the project The goal of the project is to design and test optimal MFVF, conceived for different climates in Europe (southern, central and northern) in order to improve the buildings in two aspects: -Better passive behaviour (reduction of the cooling / heating / lighting energy -Better indoor living and working conditions In order to permit the construction of facades tailored to different applications of the buildings, spatial orientations and climate areas, as well as to the refurbishment of existing buildings, different modules will be investigated.
2-Results of the project
-A set of optimal MFVF prototypes conceived for
specific climates (southern, central and northern) in Europe -A detailed study of the optimal modules
-Prototypes with experimental results (in test cells and in real buildings) -Detailed numerical simulations of the modules
-A description of the facades for different architectural requirements and types of construction
-Experimental facilities and extensively validated numerical models that will allow the design of optimal MFVF modules in situations not foreseen in this project.
3-Overview of the project The project is divided in to 13 Tasks and will be carried out in 30 months. The tasks can be classified in two stages: Stage A-Enhancement / validation of numerical models The partners have already developed codes for the detailed numerical simulation of MFVF. Before their application to the optimisation of the modules, they should be enhanced: (1) Include PCM and TI simulation. (2) Link with indoor simulation. (3) Determination of optical and thermal properties of materials. (4) Validation with laboratory set-ups and in test-cells with first generation versions of the modules to be optimised.
Stage B-Optimisation of designs Repeated simulations of a typical day in each month or season for each of the facades, climates and orientations will be done, together with simulations of typical buildings of different inertia. According to the results of the simulations, a second generation of optimised modules will be designed, built and tested in real buildings and real-scale experimental facilities.
4-Overview of the consortium There are 7 organizations in the consortium: 1 University, 2 Research Organizations and 4 Industrial companies (three of them are manufacturers of glazed facades and one is an architecture bureau specialized in architectural integration of low-energy concepts in urban buildings). Three of the industrial companies are SMEs. The organizations belong to 4 European countries: Spain, Germany, Switzerland and Finland. The Swiss partner is an industrial company and is not applying for EU funding. Southern Europe organizations play an important role in this project, including coordination.
