InHaus2 Duisburg (Germany)
Architect: Fraunhofer Gesellschaft, Markus Scheben, München und Hochtief Consult, Klaus Sabranski, Essen
The research building „inHaus2“ in Duisburg is situated in close vicinity to the University and the Fraunhofer Institute for Micro-Electric Switching Systems. Managed by the Fraunhofer Company notable German firms have united to develop and test intelligent façades, room and building systems in the inHaus2-research facility. Apart from Gartner 40 other companies are participating in this long-term project, which is sponsored by the state, the federal government and the European Union.
The East façade consists of two curtain wall types, firstly a 50 m2 double skin façade with 3.80 m wide units and room-high opening vents and secondly a further developed façade based on this type, the so-called Closed Cavity Façade (CCF) with the typical build-up for double skin façades: external (antifall protecting) single glazing - cavity with integrated sunblinds - internal double glazing.
Completion: 2008

WestendDuo, Frankfurt am Main (Germany)
Architect: Engel + Zimmermann Architekten, Frankfurt/Main
The 96 m high high-rise building is situated in the west of downtown Frankfurt, at the Bockenheimer Landstraße. The building consists of two 26-storey towers twisted towards each other and connected with each other by a glazed building joint. The building joint contains the ante-lift room and optionally a reception or meeting room. A three-storey high glazed hall connects the five-storey pedestal building in the East with the twin towers. In the north of the high building complex a five-storey building has been placed as solitary whose height and alignment is orientated according to the adjacent Miquelvilla.
The unitised double façade in area of the high-rise building covers a total area of 17,450 m2. 1,270 m2 wood/aluminium-windows with folding/sliding louvers are installed in area of the main building. Additionally there is a 500 m2 large steel-glass-construction in area of the Atrium and Atrium roof and a 550 m2 large cladding for the residential building. Altogether the delivery comprises a curtain walling of approximately 20,000 m2.
The main façade, a unitised double-skin-cladding, consists of storey-high units, sizes: 2.703 m x 3.53 m, with main building components as follows: side hung windows for maintenance and cleaning (1.25 m x 3.90 m / 0.80 m x 2.90 m), side hung windows covered with aluminium sheet for ventilation purposes (0.35 m x 2.90 m), motorised aluminium sunscreen louvers in the cavity of the double façade.
Glass: Low-E coated double glazing internally and laminated safety glass externally.
Finish: Aluminium profiles natural anodised E6 EV1 and powder coated RAL 9005.

GAP 15, Graf Adolf Platz 15, Düsseldorf (Germany)
Architect: JSK, Dipl.-Ing. Architekt, Düsseldorf
New-build landmark scheme for Düsseldorf's inner city comprising a 90 m tall, 24-storey elliptical tower and a five-storey, low-rise building. The two volumes are linked by a bridge and a glass roof.
A double-skin coupled-window façade (approx. 16,500 m2) forms the external envelope of the tower, which is ellipsoidal-polygonal on plan. The façade comprises uniaxial, storey-height units of standard size 1,367 x 3,640 mm. Roughly half of these are fitted with fixed panels, which alternate with electrically operated, outward opening, side-hung casements.
Highly reflective, partially perforated, electrically operated sunshading devices are located in the window cavity. The concave louvre assembly allows the redirection of daylight and meets glare control requirements for computer workstations.
For cleaning and maintenance, the double-light coupled casements may be opened externally from a façade access system using an insertable hand lever.
The oblique disposition of the external pane of the coupled lights allows the requirements for reduced radar reflection to be met on the north elevation.
The façade delivers the required performance in terms of thermal transmittance (U-Value < 1.2 W/(m2.K) and sound control for three different sound attenuation classes between Rw 35 and 45 dB.
Finish: aluminium sections/sheet natural anodized in E6-EV1, steel sections wet-coated in RAL 9006.
Completion in 2006

LAC - Lufthansa Aviation Center Deutsche Lufthansa AG, Frankfurt am Main (Germany)
Architects and Planning: Ingenhoven Architekten, Düsseldorf
The German Lufthansa AG is building a high-quality administration building at the Airport Frankfurt/Main.
The ground is situated in the north of the airport Frankfurt, in the east of the Kelsterbacher junction and in the west of the take-off ring between the motorway A3 in the north and the airport ring in the south.
A large surface of the building is provided with a three-storey basement, and in the centre there is even four-storey basement over an area of approximately 58.0 x 180.0 m.
Double-skin façade: The ends of the fingers are enclosed by a permanently open double-skin façade. An aluminium curtain wall is used for the outer skin. Air flows crosswise through the façade cavity. The internal skin has the same design as the timber façade described above. Combined openable double leaves in the centerline provide a further escape route through the double skin fa-çade in case of emergency.
Glazing: monolithic design glass externally, insulating glass units internally.
Finish: natural anodizing in E6-EV1 externally, Oregon Pine natural varnish internally.
Completion in 2005

SRH Heidelberg, Science Tower, Heidelberg (Germany)
Architect: Donnig + Unterstab, Architekten + Innenarchitekten, Rastatt
The 54 m tall Science Tower provides a stunning focus to the new-build scheme at the Heidelberg University of Applied Sciences, which provides an usable area of some 7,900 m2. The new building's curved façade evokes buoyant enthusiasm, creativity and innovation while the aluminiumframed glass façade symbolizes transparency and directness.
The high-rise building is enclosed by a double-skin façade comprising 790 uniaxial cladding units with insulation glazing, aluminium sheet panels and tilt-and-turn casements in the inner skin. A polygonal prefabricated panel system allows the exact building contours to be transferred to both levels of the glass façade.
Glazing: Insulated double glazed units with Low-E coating, U-Value 1.2 W/(m2oK); 8 mm toughened glass made of 2 x 4 mm heat strengthened glass with screen printing, 16 mm toughened glass made of 2 x 8 mm single glazing toughened glass in white glass.
Finish: coated in RAL 7016, light blue.
Completion: 2005

BBC Scotland New Headquarters, Pacific Quay, Glasgow (United Kingdom)
Executive Architekt: Keppie Design, Glasgow
Design Architekt: David Chipperfield Architects, London
The new headquarters of BBC Scotland was built on Pacific Quay, Glasgow, only metres from the River Clyde. Occupying a 120 x 55 m footprint, the rectangular building is some 28 m tall with a total façade area of 9,800 m2. Unitized systems are used throughout the façade, the boldly expressed, deep, continuous horizontal and vertical joints being used to dramatic effect.
The major part of the envelope (approx. 5,000 m2) takes the form of a double-skin façade with ventilation slots in the transoms and along the mullions. Partially perforated louvre sunshades are located in the cavity. Ceiling-height opening lights are provided internally for ventilation and maintenance.
The 6 m high insulating façade at ground-floor level, by dispensing with transoms, admits generous quantities of daylight into the interior.
Glazing: Low-iron glass was used throughout the scheme for maximum daylight transmission. The glazing consists of insulation glass units with low-E coating and argon filling.
All external panes and aluminium sheet were fixed to the panel frames using structural glazing technology.
Finish: sheet and sections natural anodized.
Completion: 2006
