2 IntroductionCommercial buildings, such as offices, shopsand mixed residential-commercial buildings, account for 20% of construction output in the EU, representing over 20 million square metres of floor space per year. The commercial sector demands buildings that are rapid to construct, of high quality, flexible and adaptable in application, and energy efficient in and composite constructionhas achieved over 60% market share in this sector in some countries of Europe where the benefits of long spans, speed of construction, improved qualityand reduced environmental impacthave been recognised.

3 A wide range of steel technologies may be used in commercial buildings. Specific technologies are chosen to match client requirements. Many long span steel solutionsprovide service integrationwithin their depth, which saves on building height. Cellular beams combine an efficient manufacturing process with opportunities for service integration. Integrated beams minimise the floor zone while allowing services uninterrupted access below the floor GuideCase Studies Scheme Development Flow Charts NCCI ExamplesBrussels, 18-20 February 2008 Dissemination of information workshop4 EUROCODESB ackground and ApplicationsClient Guide2.
