In cooperation with Roark Studio and Arup, we have prepared a set of analyzes and simulations for the concept of expansion of the National Museum in Warsaw.
The property on which the competition task is to be implemented is located in a unique location – at the intersection of several viewing axes, surrounded by park greenery, with a strong context in the form of the main building of the National Museum and neighboring buildings. The implementation of the competition concept with a significant impact on the functioning and interpenetration of the city park and the activation of the museum space, which used to be the back-up area, required a thorough understanding of the context of the place.
An important issue was to define the relationship of new buildings with the form of an existing building, creating strong and clear functional and compositional-aesthetic relationships, bearing in mind that the solutions are to be feasible in the future, assuming the option of staging, economic efficiency at the implementation stage and low operating costs in during the use of the building. We adopted the relationship with the main building and the surrounding greenery, functionality and creating space for social integration as an element guiding the design process.
Climate Analysis - Warsaw
In order to consciously shape the space around the building, we analyzed the factors influencing the thermal comfort for the Warsaw region.
The most important factor influencing comfort is the wind, especially in winter. The use of wind and sun protection increases the number of comfortable hours by 25%
We placed the building in such a way that it would protect the public space next to the building from western winds. Such a solution, together with the remaining tree stand that gives shade in the summer season, should significantly affect the attractiveness of the space surrounding the building.
Solar Radiation
To reduce possible overheating of the building, the following assumptions were made:
– location of the main body of the building along the north-south axis
– no glazing on the southern facade not shaded by trees
– the use of movable blinds in the office part
– the use of fixed blinds in female workers from the south side
– overhang of the entrance part
The facade of the painting studio
The facade provides natural lighting for the painting studio. In order to reduce the risk of overheating the room, we used vertical blinds which obscure the glazing.
In order to select the appropriate setting of individual blinds, a series of analyzes of the insolation of the room was carried out with a different configuration of the slats. About 1000 possible configurations were analyzed. The applied solution allows the ASE ratio from 65% to 7% (the level awarded in the LEED certification), significantly reducing the possibility of overheating and too high intensity of light in the room.
Building energy analysis
Based on the energy model, we have derived the following energy strategies for the facility:
– increasing the insulation of external partitions
– insulation of cold stores from other rooms
– the use of fixed blinds on the facade of the painting studio
– the use of movable blinds on the facade of the office part.
– no windows on the south façade of the main part of the building
Heating demand
Increasing the insulation of the partitions reduces the need for heating
Solar gains
The use of a shutter system reduces solar gains in the rooms, reducing the risk of overheating.
Cold demand
Insulating cold stores and reducing solar gains reduce the need for cold.
