The Kunsthaus, Graz
A large, shiny alien has landed in the middle of Graz, the Austrian town that is this year's European capital of culture.
This blue-scaled creature with its warty-nozzled back is the town's new art gallery – the Kunsthaus – designed by UK-based architects Peter Cook and Colin Fournier.
One of the building's more unusual features is that its unique acrylic facade is itself an artwork, which its designers, realities:united, call "an urban screen".
In reality, this is a 900 m2 facade wrapped around the biomorphic structure to form a membrane between the museum and the town, upon which computer-generated artworks will be displayed.
The screen is formed from 930 conventional circular 40 W fluorescent lights mounted behind the building's semi-transparent blue skin.
Each circular lamp forms a single pixel and is individually controlled by a central computer so that it can be turned on or off or have its brightness varied. In this way, images and films can be projected across the whole of the building's eastern facade at a speed of up to 20 frames per second.
Inside the building, fluorescent lamps have been used extensively to illuminate the exhibition floors. An inclined travelator carries visitors from the glazed entrance foyer to the enclosed first floor exhibition space.
Light on this floor comes from the battens of fluorescent lamps arranged in staggered lines across the ceiling, providing a uniform luminance across the floor.
A second travelator deposits visitors on the top floor, which features more circular fluorescent lamps. This time, the lamps form hoops of light, which line the inside of the nozzles on the top of the building. At night, these luminous hoops light up the cavernous space. Facade team

Wire ropes and clutches
Ductmate has launched a wire rope system called Cablemate for hanging building services including ductwork, pipework and electrical systems. It consists of wire rope supplied on a spool and a cable gripping device called the Clutcher. The wire is cut to length and fed through the cable grip to form a closed loop. The company says the device has a load rating of up to 113 kg and that it is set to launch one with a rating up to 324 kg.
Light switches that detect daylight
A range of lighting control devices that can switch the lights on or off and dim them when they detect daylight has been launched by Flex Connectors. These include the company's Flex 7 miniature daylight sensor, an extra-low-voltage manual override switch, and a network system to connect the devices together. The company says the products eliminate the need for complex programming and on-site commissioning of the lighting control system.
Patio doors for the home or office
Coburn Facade is a new sliding and folding door system developed by Hillaldam Coburn. It is intended for accessing terraces and patios in both homes and businesses. It consists of either three or five door leaves that have to be of equal width. Leaves are available in sizes of up to 3 m high and 900 mm wide, and in a choice of gold or silver anodised aluminium.
Modular restraints for dangerous places
Roof-edge protection specialist Kee Klamp has launched a modular restraint system to keep workers safe from falls in situations where there is no permanent edge protection and for workers installing the company's KeeGuard edge protection system. The freestanding system is shaped like a cross, with weights fitted over the four ends to weigh it down and with the anchor connection point in the middle. The weights also have anti-slip rubber pads to prevent the system being pulled along. The weights can be used as a counterbalance in the KeeGuard guardrailing system to save workers having to take them down at the end of an installation.
Quicker torch-on waterproofing
A torch-on waterproofing system called Torchtec Quicflo for roofing applications is now on the market. Manufacturer Marley Waterproofing says the system includes heat transfer characteristics to concentrate the energy from the torch on activating the bonding process, a specially modified SBS type of bitumen to combine increased speed of melt and flow with good adhesion. The system is also said to remain flexible and crack-resistant down to -10º C and resists foot-marking. Cap sheets are supplied in 8 m lengths and in a choice of four colours: brown, black, green and blue-grey.
An invisible hinge
SOSS Invisible Hinge has brought out the SOSS 218 VA, a hinge that fits between the inside of the door frame and the edge of the door, and features both vertical and height adjustment of plus or minus 3 mm.
Faster duct installation
Metstrut, which makes metal framing systems for supporting services such as cables and air-conditioning units, has launched a prefabricated solution called Rapidstrut, which is claimed to reduce installation time by 40%.
The system consists of a channel designed to interface with brackets that have pre-assembled spring nuts and bolts. These are designed to fix to the channel very quickly. The channel also comes with multi-sized slots designed to be compatible with commonly used bolt sizes.
Reversible aluminium windows
Velfac has added a reversible window with no externally visible mechanism called the 229 to its 200 series. The company says the product matches any of the other 200 series opening options, enabling designers to incorporate reversible windows into a facade yet retain identical sightlines. A new type of stainless steel hinge allows the window to rotate up to 170º. The window also incorporates safety devices, including a safety catch and child lock, plus a friction brake to damp the opening speed.

A survey was conducted on the organisation’s www.aggregain.org.uk site, which found that 81% of users were aware of the changes. The new standards aim to create a level European playing field for the use of recycled, secondary and primary aggregates.
- Two construction bodies promoting the use of IT are set to merge. Construction Industry Trading Electronically and the UK chapter of the International Alliance for Interoperability are joining forces. CITE hopes to benefit by gaining access to the IAI’s technical infrastructure and linking up with other chapters of the IAI. The IAI hopes it will gain greater exposure by reaching into the housebuilding and products sector of the industry, where CITE has a presence. Both organisations also hope to improve efficiency by combining administration functions.
- Trent Concrete has won a cladding contract worth £1m for a mixed office and residential scheme in Waterford, Ireland. The contract is for 5,000 m2 of precast reconstructed stone cladding in four different finishes.
