The building consists of one underground storey and two above-ground storeys. The main structure of the building is a column and beam system in monolithic reinforced concrete technology. The layout of the columns is designed on an irregular grid due to the exhibition rooms, which by their function cannot have integrated columns. The building is designed with 25x40cm reinforced concrete columns and a 30cm thick monolithic reinforced concrete wall. In the areas where the walls are mainly glazed, the columns are designed to be connected to the ceiling by tie beams.
The foundation of the building is designed directly by means of a slab foundation with thickenings under some of the columns and trims for the lifts. The foundation slab is designed in a "white tub" construction. The designed foundation level is -6.00 below the building (relative to building 'zero'). The foundation slab is designed with C30/37 W8 waterproof concrete. The foundation slab under the building is approximately 1 metre thick and is based on a structural barette system. External walls of the underground part - monolithic reinforced concrete wall poured 40 cm thick of concrete C30/37 W8, using the "white tub" waterproof concrete technology.
The floor slabs are designed as reinforced concrete ground beams supported on columns and bearing walls and connected by tie beams, the slabs are designed in C30/37 W8 concrete reinforced with A-IIIN steel.
The slabs are provided with openings for sanitary, electrical and mechanical ventilation systems. There are also openings in the floors for the vertical communication of the building and openings directly related to the building design.
The external walls were designed as monolithic reinforced concrete walls 20 cm thick insulated with 18 cm of mineral wool. Three different façade finishes are designed: a green façade with a fixing system for concrete panels, a façade finished with concrete panels and a glazed façade with a layer of BIPV and UV-insulating film.
The internal walls are made of 20 cm thick concrete blocks, they are finished with a plaster of a chosen colour depending on the design of the room. The walls to the children’s area are made of glass with sliding doors.
The walls in the exhibition areas are temporary walls with a metal frame filled with a “honeycomb structure from cardboard and ply wood. The wall structure is 4-6cm thick, while the whole wall’s thickness and height varies depending on the size needed for the artwork to be displayed.
The focal point of the design of the project is the river side elevation. The idea is to connect an educational elevation with the renewable energy source of the project.
As the Louvre would not be a French museum but a Polish one, the elevation adorns simple drawing of chosen facades from popular/historic/major Polish facades. They were carefully chosen from the handbook “Zarys dziejów Architektury w Polsce” (Outline of the history of Architecture in Poland) by Adam Miłobędzki. As to represent Polish architecture. The chosen buildings in chronological order are: Siedziba Bractwa Świętego Jerzego in Gdańsk, Castle in Brzeg, Siggismund’s Chapel in Krakow, Przybyłów Tenement house in Kazimierz Dolny, Sukiennice in Krakow, Ratusz in Poznań, St Peter’s and Paul’s Church in Krakow, Villa pod Jedlami in Zakopane Kamienica pod gwiazdą in Gdańsk, Tenement house on Służewska street in Warsaw.
The elevation then continues to change into a green façade symbolizing modern and future architecture, focused on energy-efficiency, and heat-reducing solutions.
The technology used in the educational faced was recently developed and patented by Olga Malinkiewicz, a Polish physician and co-founder and CTO of Saule Technologies. It’s called BIPV (Building Integrated Photovoltaics) where solar modules are an integral part of building elements. They are lab created perovskite solar cells which are semi-transparent and printed on flexible foils which are then laminated between layers of glass. The printing production technologies allow freedom of shape and easy pattern scaling, thus printing of the prepared drawings of facades is possible. The cells can even be material-engineered to have different colors and transparency levels.
In-between the BIPV Panels, on the first floor, will be regular floor to ceiling windows with a UV reflective film layer between the glass, as well as solar screen mounted from the inside to limit light in the exhibition area when needed.
As birds are unable to pick up clues to find that windows are present and frequently don’t survive the impact, designing a building on the river-side surrounded by nature must take this into account. In this design a special type of glass is used: UV reflective first layer, triple glazed to limit heat transfer and over-heating inside the building which is harmful to art and a bird safe ultraviolet film is installed between the first and second layer of the glass. This film invisible to the human eye reflects UV rays in a pattern only visible to birds thus avoiding collision. An example of this glass is the Bird Safe Glass produced by GlassPro in the United States.
On the green façade a modular trellis system from Jakob rope systems is used. It’s made up of horizontal bars that anchor vertical cables, which offer stability and easy installation. A security mechanism protects the cables and the carrying structure from overload dues to excessive plant weight, wind, snow or other loads. Cable diameter and mesh aparature are specially adapted to climbing plants. Webnet is a design solution for dense façade greening and plants with a high leaf area coefficient, useful for passive binding of airborne dust particles, shading of glazed areas, refracting traffic noise and other environmental services such as providing passive cooling and shade by evapotranspiration and bio-diverse habitat for birds and insects.
A green roof has been designed on top of the flat roof. Layering according to the intensive green roof principle. The roof pitch is 1.5%. The green roof is covered with plants such as Sedum spurium, Widow’s cross, White stonecrop, Gold sedum, Houseleeks, Yarrow etc.
