Green Architectural Membrane

Kenaf plant

A green Architectural membrane, based on Kenaf bast fiber has been developed by Taiyo KogyoCrop.  Kenaf is a natural fiber and have similar characters as Jute. Kenafine^TM, developed by Taiyo Kogyo Crop., is made by weaving Kenaf fiber with polyester fiber. This bas fabric is coated on top with photocatalyst TiO₂  and at bottom coated with antibacterial agent of silver. This environment friendly green membrane can be recycled to make paper product¹. Thus it is more carbon-neutral than 100% polyester based fabrics. Test result of Kenafine is given below.

Europe Tour Part 03

After visiting Paris, I headed to Amsterdam next week. It was my dream to visit Amsterdam. I reached Amsterdam on 28th April 2012 night. Though It was cold and windy, I got out with my camera to take some amazing night shots of Amsterdam.

Amsterdam at Night

Amsterdam is the largest city and capital of Netherlands. The name is derived from the dam on the river Amstel. With my dutch friends John and Aukje, we visited different parts of the city and buildings. We made a boat trip through the canals of Amsterdam. I ate totally raw haring fish in pure dutch style. We also visited a small craft museum, where we saw traditional wooden shoes, cheese, clothing etc.

Me with my friend John and Aukje

Traditional wooden shoes

We visited Nemo, designed by Architect Renzo Piano. It is a kids science museum, which looks like a ship. Beneath it there is a road tunnel connecting other part of the city. We also visited Whale a residential building resembling whale in shape. It is designed by Architekten Cie. It was quite a impressive building in terms of massing, fenestration.

The traditional pitched roof brick houses were impressive.  There was a hoisting steel plate at the top of each house to lift goods to different floors through large windows. There are numerous famous buildings all around Amsterdam. Unfortunately I couldn’t able to visit all of them in time. I wish I could spend few weeks in Amsterdam to explore all the places.

Europe Tour Part 02

I made a trip to Paris on 21st April 2012 from Antwerp, Belgium. It was great as well as romantic as I saw in the movie"Midnight in Paris". In my opinion it is the best among other european cities I visited. The calm Seine river, trees, walkways, parks, huge boulevards, tourists, beautiful modern, post modern, classical buildings made Paris an unforgettable city.

Notre Dame Cathedral from the bank of river Seine.

Glass Pyramid lobby of Louvre Museum

I went to magnificent Louvre Museum where I saw Monalisa, the Captive by Michelangelo, apartments of Napoleon  and numerous paintings, sculptures. Glass pyramid lobby of Louvre museum designed by Architect I M Pei was impressive. The collection of paintings and sculptures of Musee de Orsay was also impressive, where I saw the paintings of impressionist artists like Van Gogh, Claudia Monet, Pierre Auguste Renoir, Paul Gauguin, Edouard Manet etc. I also visited world famous cathedral Notre Dame. As the name of my college was also same in Bangladesh, it was a great opportunity for me to visit that cathedral. It was the finest example of French Gothic Architecture in medieval time. It was highly decorated with sculptures of christian beliefs and with most delicate stained glass.

Georges Pompidou Center

Me infront of Arab Institute

I visited some of the famous modern architecture in Paris like, Georges Pompidou Center, Arab Institute, La Defense. Transparency of Pompidou Center was amazing, where anyone could see the structure of the building, mechanical facilities as well as circulation of the building. Arab Institute was famous for its facade which was constructed with series of shutters. These shutters could open or  close automatically depending on solar radiation penetration through the facade. But unfortunately these were not working anymore. La Defense was a business district where you could see modern skyscrapers. Grand Arch of La Defense was outstanding. It was a complete frame which was axially connected with city center. It was designed by Johann Otto Von spreckelsen.
It was worthless to visit Paris without seeing Eiffel Tower. Eiffel Tower was a master piece of delicate steel work. It was huge in height as well as beautiful. It was breath taking to see Eiffel Tower from distance against city fabric.

Europe Tour Part 01

It was a great Europe tour.I traveled so many places. I visited four countries Germany, Belgium, France and Netherlands. I started my journey from 6th March 2012 in Dessau, Germany where I attended my 3rd semester in IMS. Then me with some of my Indian friends made a trip to Munich on 18th March, it was a "membrane tour". We stayed there for three days and visited Olympic stadium, Allianz Arena, BMW Welt. We also visited a material exhibition at Messesee, Munich.

Then on 21st March I traveled to Antwerp, Belgium for my Internship training in Nomad Concept. Antwerp was a great city. There were so many things to see, luxury shops and nice pedestrian walkways in Meir street, great plaza of Grote Markt, 572m long pedestrian tunnel under the river Scheldt, greatly sculptured Antwerp Cathedral with a huge tower which could be seen from all parts of the city were some of the jewels of the city.

Antwerp at night, Meir Street.

Antwerp at night was spectacular. Roads and walkways were flooded with light. There were fountains illuminated with light. Some significant buildings were also washed with light. There were diamond shops in Antwerp. Lights from glittering diamonds also add more lights to city fabric. It was very pleasing to walk around at night and enjoy the beauty of the city.
There were some architectural jewels in Antwerp like MAS museum of Antwerp which was a great modern museum, Antwerp Courthouse by Architect Sir Richard Rogers was another great architecture to visit and the Centraal Rail Station of Antwerp was truly magnificent with its huge vaulted lobby. It was a nineteenth century architecture but a new extension with modern design was built which was also very impressive and spectacular.

I will never forget my stay in Antwerp for 2 months. It has so many things to remember but the breath taking view of Antwerp at night from the bank of the river Scheldt was unforgettable.

I also visited other cities of Belgium like Ostende, Ghent, Leuven, Tongeren, Turnhout, Mechelen, Liege, Brugge and Brussels. Liege rail station was a magnificent structure designed by Architect Engineer Santiago Calatrava. Ostende was a beach town where I saw blue north sea. Central African Museum at Terfuren Brussels was great.

Munich tour, March 2012

Me, Imran bhai, Siddique bhai and Milind made a trip to  München (Munich) on 18th March 2012. We were focused to see membrane structures of Munich. We visited Olympic stadium, Allianz Arena, BMW welt. We were amazed to see the details of Olympic stadium of Munich. Architect of this stadium was Frei Otto, one of the pioneer of tensile membrane structures. It was built for Olympic games in 1972. Another great stadium in Munich was Allianz Arena. Its a very impressive stadium. It was designed by Architect Harzog & de Meuron. Exterior facade of Allinaz Arena is made of translucent ETFE foil. There are lighting system to illuminate facade with different color depending on the teams playing there. The station near to the Allianz Arena was also very impressive. Roof of that station was made of translucent white membrane. Another exiting building we had visited was BMW Welt. It was designed by Coop Himmelb(l)ou. Spaces inside was very fluid and lofty. Columns or supporting structures were subdued and sometimes hidden in huge volume of space. 

We also visited a material exhibition at Messesee, Munich. Where we had the opportunity to see different kinds of materials available and technological progress.

Munich city itself was very beautiful. I specially enjoyed beautiful classical architecture on the banks of river Isar. It was a great tour. I will miss Munich very much.

IMS, March 2012

Its a great experience full of excitement for us in IMS, March 2012 . At the beginning of our 3rd semester classes Imran bhai, Siva and me presented our group work. There were lectures from the representatives of  Cenotec, Mehler which were very inspiring. Then Harry taught us how to weld fabric. That's a great experience for me. We have also installed a tensile fabric in IMS campus. Then we visited Novum factory, it was a huge experience for me as we saw how fabrics are fabricated specially ETFE foils. In total I can say that my experience during this semester in Dessau was full of excitements.

I am presenting our assignment.

MM04 Structural Design and Detail: Assignment

The railway station for Ethiopia is consist of series of eye loops supported by steel columns and cables. The eyeloops will reflect light and collect water in rainy season. The project was developed in previous semester in MM01 Architecture. In this semester Imran. Siva and me worked as a group, I led architectural part, Imran bhai and Sivaji did detailing part. Here we made some changes such as concrete columns has been replaced by steel columns for flexibility and at both end additional columns has been added to reduce deflection in fabric. Eyeloops will covered by translucent fabric.

OM01 Pneumatic Assignment

In my OM01 pneumatic  assignment I have presented an idea of Pneumaloud. PNEUMALOUD word is a fusion between Pneumatic and Cloud. Inspiration of this pneumatic structure is undulating and curvilinear character of cloud. The primary structure is comprised of series of rhythmic steel arch
connected by intermediate lateral steel tubes. Pneumatic ETFE cushions are fitted in between the steel arch. For solar shading, louvres are installed between the layers of ETFE. For internal air ventilation operable louvres are used at the end arch.
