Chamber Music Hall Most chamber music halls are a painful compromise between the desires of the architects and the requirements of the acoustician, where neither party is ever fully satisfied with the result. To avoid this situation, the design was divided into two working realms- that of the architect and that of the acoustician. This was possible by the choice of the horizontal lath structure that permits sound waves to travel across the room, whilst concealing the awkward acoustic requirements for the geometry of the walls. In this way, the acoustician could work independently of the architect without having to change the visual aesthetics of the room. The functionality of the design is based on a report by the leading sound engineers of PEUTZ created for a larger concert hall in the Muziekgebouw aan’t IJ, Amsterdam.

The needed degree of irregularity was integrated into the ‘shoebox’ design of the hall to avoid overlay of sound coloration, by means of the milk glass ‘windows’. These are connected to the outer façade windows by a small box-like shape, with integrated lighting. This allows for natural light to fill the chamber hall during the day. In the evenings the artificial light is used. In this way the concept of the lantern is strengthened- the windows shed light to the streets as well as to the hall when a concert takes place.

Task: The purpose of this project to provide an urban planning and architecture solution to improve the conditions at the Mehringplatz in Kreuzberg, Berlin. As a starting point we were required to study a functioning space, the Oranienplatz also in Kreuzberg, and compare the two. Thereafter, we were asked to identify ‘tools ‘ with which we will serve in our proposition for developpement of the site. Our proposition is composed of an urban densification plan based on the Tubingen Model, an opening of the Mehringplatz and the creation of a rooftop panorama within the inner circle of the square.
Background: The Mehringplatz, Kreuzberg Berlin The Second World War provided the possibility to apply the principles of the 20s and 30s to practice. The new, clear geometry should reflect the new zeitgeist. Large architectural forms according to the motto “light, air and sun,” and generous transport infrastructure were the result. Following the 60’s criticism and the demand for integration and compaction began to grow. Hans Scharoun stressed the need for a social habitat with his 1962 design of the Mehringplatz, for which he chose the circular shape as an “exemplary monumental structure”. In 1968, the architect Werner Düttmann took over work on the square. His buildings are still a major influence on the cityscape. The contemporary historical background, as well as the scarce financial resources have failed on the intention Scharoun, according to present understanding. What remains is an expressive architecture that must be handled.

The Mehringplatz
The Oranienplatz The Oranienplatz is located in the district of Kreuzberg and can be summarized through a narrow, mainly gründerzeit building structure. The neighborhood thrives on its density and diversity: the short distances, the wide range of restaurants and retail, good transport links and the high degree of housing. In addition, different spatial conditions are provided for due to the square’s diverse material.

The Mehringplatz acts more like a wound in the cityscape, as the end point of Friedrichstrasse: Traffic flushes the area, the The square unviels itself abruptly and buildings are monotonic and the height thereby draws the visitor into its dynamic. gradient of houses seal the area “hermetiIt acts as a high-traffic intersection and cally” from the rest of the city. thus plays an important role in the district. There are large spacing areas between the buildings, which act as a barrier between the square and the residential areas. There
is a lack of open passages and visual connections that announce the square. As a result, the place looks deserted and static. Even the use of commernce in the second ring contributed little to the revitalization of the inner square. For visitors, a trip to the area offers few incentives.

The traffic analysis shows that highly frequented roads have and insulating effect of the high-traffic on the Mehringplatz. The neighborhood is connected by only two service roads. The pedestrian flux and its quality is inhibited by the large parking areas.
The residents’ access to green spaces is abundant in the area surrounding Mehringplatz. Expansive public parks are located on its north and south. Although generous in quantity, these the green areas are in poor condition The square itself is sparsely vegetated and creates no clear atmosphere.
The map illustrates the concetration of restaurants and retailers around the Friedrichstraße and the outer ring of the Mehringplatz. However vacancies are also present and the inner ring provides no retail possibilites. Here lies a potential for the square to be used and revived.
The extended local supplies reffers to historical and contemporary Cultural buildings, which characterize the district and make it attractive for external visitors. The architecture of the Mehringplatz falls into this ensemble. This analysis shows the indviduality of Mehringplatz’s form in the context of its socio-political background and geographic location.
A strength of the area is its good connections to public transport.

Design and use Mehringplatz in Berlin lacks particularity, charisma and magnetism. The solution is the reuse of the inner ring’s roof, as an extension to the square.The new space is highlighted by views directed at the end of the Friedrichstrasse and the influencial remnants of the 60s and early 70s that dominate the area. Important for this promenade of 400m is its space zoning. Three irregularly repeating typologies can be found: outlook areas, characterized by a solid flooring with seating and reclining options, green areas to walk and relax, and exhibit space for art works. References for the design are the “ High Line “ Park in New York and the “Lover’s Bridge” in Sofia. The Mehringplatz, however includes an outer walls that open up to certain views and otherwise serve as exhibition spaces. By framing the views, the outlook becomes a curated one, which takes into account the privacy of the nearby residents. The open air gallery is the heart of the project. It is a place of encounter and exchange, bringing people together indiscriminatly around the works of established and unknown artists.
Outlook areas Green promenade Exhibit space
The gallery fits seamlessly into an ensemble of historical and contemporary cultural buildings, and lives to tell its own story. The design highlights special urban form of the existing constructions that define the circular square and its particular context.

Spatial dimension The section shows the height gradient and the spatial dimension of the Mehringplatz. The inner ring with its 15m is the lowest form. Seen from the roof level of the small inner ring the surrounding 50m high residential constructions look even more impressive. The height of the roof is also optimal for a glimpse into the Friedrichstrasse and a pleasant perspective on the square. The diameter of the ring is 120m thereby preventing private disruptions to the resident directly inside the ring.

New buildings in the neighborhood A densification after the “TĂźbingen modelâ€? is planned to deal with the oversized empty spaces in the neighbourhood. In this model different owners and building communities have the opportunity to create houses with innovative residential and usage concepts. A general requirement is only a development plan, which sets out the parcelling and rough conditions, as well as a rough style guide. The building blocks of this urban densification are being considered as a multi-story town houses and apartment buildings of different cubature and ensure the quality of the individual building for a heterogeneous colorful, urban image. Private and community gardens to the rear of the houses complete the picture and provide the necessary space for the residents. At the base of our urban densification multi-story town houses and apartment buildings of different shapes, which provide a quality of building that promotes a colourful, heterogeneous urban image. Private and community gardens to the rear of the houses complete the concept. The new construction are planned attractive and affordable for families as well as for individuals of different generations, nationalities and income levels, to provide for a mixity of residents.

Construction:
the form of images covering blank walls as in variations of the disposition of the cables (whilst minimising affectation on the existing openings), and also a certain wave-pattern visible when looking at the fassade sideways.
Cables would be connected to joists sticking out from the Fassade. Usage of parametric design methods: The use of a parametric design approach is advantageous as it allows for arandomised image to be created without recurring necessarily to classical pictures the first female Professor of Architecture in or patterns. Its parameters also allow us the DDR, Arch. Anita Bach. to control its influence on the openings, strength of the variations, etc. Therefore, the result looks organic and random but can be controlled without having to manually define every line.
This design was planned particularly for the twelve story high Jakobsplan student dormitory. The Jakobsplan is a controversial pre-fabricated panel block located in the center of historical Weimar. It was completed in between 1970 and 1972 by
The same project can be applied to different buildings just by drawing the basic façade module in Rhino and defining total length and height of the fassade as well as which images and patterns to use as reference.
Project info: Idea - Design goals: Our proposal attempts to create a low-cost aesthetical solution for the façades of highrise, prefabricated buildings which fill our cities with grayness. Without recurring to a whole reconstruction of the façade, or just repainting them in bright colours and patterns, we propose to give them a greener image, recovering and this time making true Le Corbusier’s ideas of the block surrounded by green. Also, to avoid uniformity each of the buildings would have varying patterns, both in

Principles of the design: Open access areas should be easily accessible and are therefore located on the ground floor. The cafeteria is open to the street, inviting passers-by to enter. In addition, the library is concieved to create a transparency between the generous interior garden and the street. Garden access provides a possibility for outside work protected from the street noise . A double orientation would create to open on the south for light and one to the north to protect the shelves from direct sun light The multipurpose room is open to the garden too allowing the space to expand as needed. The building can be completely traversed without going outside.

The building’s relationship with its immediate environment _ To optimize access and manage the flow _ Control modes of transport to encourof visitors age those who are less polluting for optimal functionality Access to the underground parking was placed at the bottom of the plot so as to provide the cafeteria with a terrace and open the building towards the larger treet. There is no interruption of the sidewalk, allowing legibility and providing maximum accessiblity for pedestrians and disabled persons.
The parking was planned with respects to the number of seats required by the regulations and the desire of the client. It contains 80 spots for a maximum of 400 people, who can be accomodated by the compex. The complex is also located within 400m of a tram stop.
_ Environmental integration of exterior facilities A secure bicycle parking with 78 places can be found near the entrances accomodating a number far greater than the number of employees. These are weatherproof and an important part of the complex. Showers and changing rooms have been placed in administration for employees arriving by bike.
For a good relationship between the building and its environment, no fence was placed between site and the public space. The building itself serves as a barrier to privatize the inner garden as requested by the client.

Acoustic comfort _Optimization of space configuration The main structure of the building is a post and beam construction. Given the large spans of the overhang amphitheater a different structure would be applied. At its base, it consists of rigid steel frame resting on a ball joint and attached to an anchored tie rod. Therefore, the weight of the rigid box is stabilized by pulling tension.
Noisy areas are: The amphitheater The cinema Both immersive rooms
The library has been completely isolated from the rest of the building. The offices are located at level 3 at a safe distance from the main traffic. They are close to the amphitheater, as the use of these two functions are expected to differ in time. Despite this a sufficient sound insulation is to be forseen. The two cinema halls are separated, so there is no risk of interference during a projection.
Multipurpose room and cafeteria space can be noisy or quiet by hours and are therefore not sensitive areas in terms of acoustics. This complex is multifunctional, each function is used at different times in the day.
The library was opened visually towards it to allow a transparency towards the interior garden because expected external noise is not significant. The library is however completely sealed off physically, as none of its openings face the street.
The areas requiring quiet are: The library and media Office space
_The acoustics of the amphitheatre Measures have been considered to satisfy a homogeneous distribution of sound in every point of the room. The ceiling direct above the amphitheater is considered such as to disperese the soundwaves by means of reflection. The stepped arrangement of the audience promoted absorption, which in turn requires less treatment to the walls and the ceiling furthest from the screen. For the ceiling directly above the audience absorbent panels have been chosen.

Amphitheatre The problem of location with regards to sightfields is present in nature, as plants face similar issues to expose their leaves to sunlight. Because surface area is a limiting parameter, it has been observered that plant align their leaves following the sequence of the fibonacci spiral to optimize their exposure. For this reason the seating arrangement in the larger projection hall was modelled parametrically based on the fibonacci spiral so that no seat is directly before a preciding one. This optimized the sightfield of the seats and allows for a smaller
slope within the amphitheater.
Acoustically, the geometry of the amphitheatre is advantageous as In addition, a fan shape box form was its shape follows that of the moving choosen for this projection hall to soundwaves. In addition, the fact that complement the seating arrangement. the walls are not parallel reduces the

A solar study conducted in Ventilation installation Revit confirmed The inclined southwestern roof surface will be covered with photovoltaic solar panels. The choice of this type of panel was made because the hot water needs of the project are very low and therefore it would be more interesting to produce electricity.

For the determination of the gloabl impermability coefficient, the individual coefficient and surface area of all the types of green spaces, paths and roofing in the project were considered. Based on these:
This calculation takes into considertation flushes, faucets, sinks (including those in the kitchen and cafeteria), urinals and showers. For this the staff was considered in terms of 15 permanent occupants. The visitors were taken into account as an average of 800 people a day with a residence time of 3 hours.
The surfaces taken into consideration are: Impermeable roof with solar panels: 180 m² Impermeable roof on East: 150 m² Terasse surface: 111 m² Area of extensively vegetated roofs 586 m²+ 303 m² Total: 1331m²
The impermability coefficient of the ground soil is 0.61.
The water needs of the project were deterThe global impermability coefficient of the mined with the aid of the software provided plot is inferior to 65%, thereby satisfying HQE by Certivéa. Based on the above, the water needs of the project = 0.57 that of the requirements. reference value. This corresponds to the HQE standard requested.
Considering roof surfaces and the month with the most abundant rainfall, we can collect 2,377 liters of water per day for the month of March and an average of 1422L of water per day during the year.
The rainwater harversting tank is sized as to have a autonomy of a month, that is to say 30 days. Its has a storage capacity of 5.5 m3 to 100m ² roof and it is planned to be empty 7% of the time. This percentage is not to be exceed to avoid the pumping of suspended particles or other deposit. Furthermore, to favour the quality of the water, the tank has been considered slightly smaller at 70m3. This allows for an overflow that evacutes the surface layer and floating debris. The rainwater harversting tank covers approximately 57% of the complex’s water needs. This meets the HQE regulations.

_ Hygrothermal comfort
_ Controlled mechanical ventilation
A double skin was placed on the south side of the library to reduce heat loss and use the greenhouse effect to warm the library and ventilate it naturally. The double skin protects from the cold and stores heat by absorbing variations in climate thereby maintaining the temperature of inside spaces. Curtains will be placed between the two walls to control the access of sun in summer.
The mechanical ventilation system comprises an air extractor for depressurizing rooms connected a network. This is an extractor fan is often located in the roof. Putting a room in depression ensures that wet or particle loaded air does not flow through the rest of the building. This depressurization also allows outside air to penetrate more easily through the air vents usually located above the joinery.
Ventilation occurs of the shaft box manner, where vertical ducts are connected to the The mecanical ventilation is to run continumodule each floor, allowing for an increased ously to always renew the stale air in rooms circulation. where bacteria and odors are present, such as in sanitary areas and the kitchen. There will be two ventilation systems because the
dry parts do not need to be continuously ventilated.
Natural ventilation is also provided for in the form of traditional windows.
The second ventilation system will be provided by a double flux ventilations which filters the used air and infuses it with fresh one before reintroducing it into the rooms. This ventilation is provided with a heat exchanger to preheat the incoming outdoor air in winter. This method allows to reduce heating needs. For the cinemas, ventilation will to arrive from the seats. This provides the visitors with fresh air, whilst not losing energy to heat the space in its height.
