5 real-demo-cases have been selected which on top of covering different building typologies and climates (Continental, Mediterranean and Oceanic) will also test different solutions offered by the BIO4EEB project.
Multifamily multi-storey residential refurbishment in Lithuania
A typical multi-apartment post-Soviet style residential building was chosen to demonstrate new renovation opportunities. The total floor area of building is 1100m2 and the total area of external walls is 1350 m2. Two apartments on the ground and first floor of the building were selected to test Bio4EEB technologies. The rest of the building will be insulated with stone wool in traditional way. The demonstration part of ground floor will be arranged with Bio-based (PLA and Polyurethane foams) ventilated façade (total are of 62 m2). The first-floor apartment will use internal insulation technology with Posidonia + PECs Bio-based panels (58 m2). Eight pcs. Bio4EEB windows (2 units of 1.23 x 1.30 m2; 4 units of 1.50×1.30 m2 (with inner partition); 2 units of 2.20 x 1.30 m2 (with inner partition) and two balcony doors (0.80 x 2.20 m2) will be used for the renovation of selected apartments. The entire building will be covered with a frame structure that allows the use of traditional stone wool and BIO4EEB technologies. It will also allow the entire building envelope to be covered with stone tiles while maintaining a unified architectural style. This method of insulation will open up the possibility to test, evaluate and compare the project technologies with the standard one.
Historical/protected residential complex refurbishment in Spain
This demo case residential complex was built in 1930s and is located at the northern part of Mallorca Island. This building is listed in the Catalogue of Elements of Artistic, Historical, Environmental and Heritage interest in Mallorca. Its protection level is subject to protection of certain elements, such as facades, terraces and gardens. The building has 3 floors (ground floor, first floor and attic) with a total of 600 m2 built area. In the whole house, there are original wooden windows without isolation and the typical Majorcan wooden/aluminium shutters. The roof is covered with clay tiles. The purpose of this demo-case is to demonstrate interior BIO4EEB renovation technologies’ performance in a historic residential building. As it is a protected building and the façade cannot be changed, all the renovation activities will focus on internal envelop with Posidonia + PECs Bio-based foams and installation of new windows of Bio-Polyurethane.
Single family residential refurbishment/new construction in Germany
This demo case was built in 1950 as detached single family house, now it will be restructured, modernized and extended as an apartment house with 3 condominiums. The total floor area is 425 m2 + 112 m2 in the cellar. The total area of external walls is 420 m2. The purpose of this demo-case is to demonstrate the application of the BIO4EEB technologies in new and existing buildings. The pre-fabricated rooftop extension and the new north façade were selected to test Bio4EEB technologies as panels and insulation on the exterior walls and on the roof. The north façade on the first and second storey are an additional opportunity to install and test five BIOPolyurethane windows in two different sizes and partitions. Approximately 115 m2 of the bio-based prefabricated façade will be applied to the roof-top extension walls whereas 65 m2 of the bio-based ventilated façade will be applied on the new parts of the north façade. The new rooftop is an opportunity to apply and test Bio4EEB panels and insulation on a surface of approximately 95 m2. The rest of the already existing exterior walls will be cladded with a conventional thermal insulation composite system. The implementation of conventional technologies and innovative bio-based Bio4EEB technologies at the same time will provide the opportunity to compare these.
Rural single family residential refurbishment in Czech Republic
The un-refurbished Czech rural houses built in the period 1921-1945 have rather poor energy performance. The energy saving potential of this part of the Czech housing stock is worth paying attention. About 60-70% of rural buildings originating from the pre-war period do not meet the current energy efficiency standards. This demo site is a typical rural family house built in 1927. Bathroom, kitchen, toilet, living room and one bedroom at the ground floor. Two bedrooms in the attics. All the vertical load bearing structures are 450 mm thick masonry cavity walls with 150 mm air space. The floor structure above the ground floor is a timber joist ceiling. The roof truss is made from timber and the roof is covered with clay roof tiles. The total floor area in the house is 144 m2. The conditioned floor area is 127,7 m2. The windows are wooden box-type windows, already renovated, the outer sash has a double glazing.
Multifamily multi-storey residential new construction in France
The project in question is in-house project of BOUYGUES CONSTRUCTION, it is about the transformation of an industrial site (a chocolate factory) in several types of buildings: housing, co-living space, presence of a hotel and all this in the urban environment of the Ile de France region. Several of the existing buildings are protected as historic monument. The ambition of this in-house project is to offer an exceptional living environment, reinforcing social interaction and intergenerational links and also protecting biodiversity with the development of “green” areas. BIO4EEB will focus on a residential building named “Platane” . It will be built in 2024. The purpose of this demo-case is to demonstrate the application of the BIO4EEB technologies in new buildings. 2 apartments on both sides of the building are selected to test Bio4EEB technologies as prefabricated façade and insulation on the exterior walls. The façade is an additional opportunity to install and test ten BIO-Polyurethane windows in 3 different sizes and partitions. Approximately 100 m2 of the bio-based prefabricated façade will be applied to the walls. The rest of the building will be cladded with a standard bio-based insulation composite system. The implementation of bio-based technologies available in the market and innovative bio-based Bio4EEB technologies at the same time will provide the opportunity to compare these.
