Txog ETFE Membrane Facade Kev Ua Haujlwm Tseem Ceeb: Phab Ntsa Nyias Ob Txheej

Ntawv Qhia: Phab Ntsa Nyias ETFE yog ib phab ntsa nyias ob txheej (double skin facade) uas tsim los rau lub tsev tshawb fawb thiab qhia ntawv. Daim tawv sab nraud tsim los ntawm cov hnab tawv iav (cushions) uas muab tshuab kib ua ke ntawm ethylene tetrafluoroethylene, dav peb mev thiab ntev txog rau caum ob mev, khaws cia nrog qhov nyos huab cua ruaj khov thiab txawb rau saum lub qauv hlau thib ob (secondary steel structure) nrog cov hlau xuas tuaj lug (aluminium clamps) raws txoj kab dhia (diagonally). Qhov qhov nruab nrab ntawm phab ntsa (facade cavity) ua hauj lwm zoo li lub cuab yeej sau lub hnub qhia kub (solar collector), thiab huab cua kub raug rub mus rau hauv cov chaw ua pa cua (ventilation units), qhia txo tau kev siv zog txog li 30 feem pua. Daim tawv iav no raug ntxuav los ntawm dej nag thiab pab tiv thaiv suab nrov los ntawm kev khiav tsheb ntawm txoj kev.

Yam Tshwj Xeeb: Applying Double Skin Facade with ETFE Ethylen Tetrafluor Ethylen transparent membrane assembly for energy saving up to 30 percent. Acting as solar collector with recuperation of hot air on the top floors in winter season.
Additional acoustic protection on busy traffic streetscape.
Aesthetics, added value as large span between structural members.
Self cleaning exterior of the facade ETFE membrane with additive chemical component rejecting dirt as automatic cleaning of the facade with rain water.
Qhov Loj & Ntim: Pneumatic ETFE membrane cushions are 3 m wide and up to 62 m long, installed diagonally and kept under constant air pressure 300 Pa.
Cushions are anchored on secondary structural steel system with aluminium extrusion clamps structurally designed for wind load.
Acoustical properties in combination with triple glazing system 47 dB adds 10 dB to 57 dB in composite calculation.
Area of ETFE membrane facade is divided in two parts 1294 m2 and 570 m2.
Height of facade 20 m. Length of facade is 68 and 30 m.
Cov Ntsiab Lus: ETFE, Ethylen TetraFluor Ethylen membrane, Double skin pneumatic facade,
Thev Naus Laus Zis Tsim Khoom: 3 m wide ETFE Ethylen Tetrafluor Ethylen cushions in south and west facade with seam in aluminium profiles on the secondary steel structure are welded cushions and kept under constant air pressure 300 Pa.
Weight is 1% of glass installation of outer skin.
Recuperation of hot air from facade as solar collector, energy saving up to 30%.
Self cleaning exterior ETFE membrane with additive chemical component rejecting dirt cleaning of the facade with rain water.
ETFE 50-years lifespan of the material.
Kev Sib Tw Tsim Qauv: Turning of the corner of diagonally placed pneumatic cushion of ETFE membrane detail in double skin facade.
Special aluminium extrusion detail was developed (with live size models) especially for this project to allow the twisting diagonal clamp with 1000 mm radius, placed on secondary steel tubing. We had to comply with European standards DIN different for aluminium and steel. Large mock-ups, samples and models were part of the design process to make sure that the membrane does not wrinkle.
Kev Tshawb Fawb: Design research was very complex with scientists, structure engineers in applications ETFE membrane around the world (London, Munich, New York) - design datas with manufacturers, designers.
We searched design and structural properties of Ethylen TetraFluor Ethylen transparent membrane facades for building types use, duration in life span, wind load on pneumatic cushions, aluminium clamps detailing, secondary steel structure detailing, transparency properties, weight, width versus span dimensions.
Kev Txhawb Siab: Presentation of 8 x 6 m sample of ETFE membrane cushion with pneumatic equipment for Allianz Arena in Munich by Herzog De Meuron Architects. It was used for football stadium, in England for museum in Leicester by Nicolas Grimshaw and other non transparent use. After researching those study cases around the world, later came to me the idea to use transparent double skin membrane for office type building for scientists, using transparent film membrane in double skin facade instead of glass.
Lub Sij Hawm Ua Hauj Lwm: Project design started in 2008 in Prague with presentation to Technical university scientists committee.
Realized in years from 2015 to 2017 on Czech Technical University in Prague campus for Czech Institute of Informatics, Robotics and Cybernetics of the CTU in Prague.
Txheej Txheem Ua Hauj Lwm: Applying double skin facade with ETFE membrane assembly for energy saving with recuperation of hot air on the top floors, saves 30 percent of an energy consumption.
From double facade acting as solar collector hot outside air is sucked into the ventilation HVAC units on each floor from two places - from south facade for the winter and transition period and from the north facade in the summer. (Solar collector - double facade between the glass facade and the outer facade of the ETFE facing south).
Cov Patent: Design of pneumatic cushions fasade with ETFE Ethylen TetraFluor Ethylen trademark Taiyo Europe.
