can therefore be thermally recycled and returned to the natural life cycle. Concrete elements such as ramp panels, swelling mortars and the concrete panels of the park decks can be reprocessed as recycling material, as can the steel components. A car park made of beech LVL can therefore be seen as a large resource reservoir. From an ecological perspective, this is an important aspect as it saves natural resources and makes an important contribution to preserving resources and the ecosystem. The architectural design of a prototype To test the construction system, a location-independent prototype was designed. A split-level arrangement with floors offset by half a story was chosen to enable short ramps and to achieve a cost-effective ratio of circulation space to parking spaces. The length corresponds to the maximum possible fire escape length of 50 meters in large car parks. The resulting building is an 88 Ă— 34.5 meter large freestanding volume with four stories of car parking providing space for 480 cars. With a total height of 12 meters and an upper deck finished floor level of 8.80 meters, it corresponds to building class 5. Two sets of stairs are placed along the building faĂ§ade to serve as fire escape stairs. To protect the timber structure and to provide covered parking on all levels, a roof was planned for the top floor. All car parking spaces are therefore equal; none are subject to snow and ice in winter, or to overheating in summer. An economical variant using

a sheet metal profiled roof is proposed for the roof with a fall of 2.5 % and an anti-droplet coating. The building is stiffened in the transverse directions by the reinforced concrete walls of the staircase and in the longitudinal direction by steel wind-braces in the axis of the columns. Conclusion If the specific requirements of protecting beech timber constructions against the effects of the weather are taken into account and effective means are taken to protect against moisture ingress through the design of the construction and the organization of the construction process, the building system for car parks made of beech LVL represents an ecological alternative to similar constructions made of concrete or steel. They are comparable in cost and the end result is very attractive in its design.
