AVL is the world’s largest independent company for the development, simulation, and testing of drive systems – from combustion engines via hybrid systems, electric motors and batteries to software. Designed by ATP Frankfurt in just 15 months the new Tech Center for AVL is a fully variable technological, production and office building for the automotive industry. It enables the client to react extremely quickly to the needs of the market, a feature that is especially significant in the automotive sector. Of particular importance to the industry are the variable capacities of the new AVL plant and the excellent, traffic-friendly location on the A81.

The new AVL Tech Center, which meets the latest standards in terms of equipment and efficiency, is a development and testing center for vehicle power chains and drive systems. It contains two emission and NVH four-wheel-drive roller test stands, several HIL systems, a NVH motor test stand, two power train and, initially, four motor test stands. A total area of 20,000 square meters includes vehicle and motor assembly facilities, workshops, laboratories, and storage and office areas.

ATP sustain designed the energy concept in cooperation with ATP Frankfurt and was commissioned to carry out the buildings physics verifications in the areas of thermal and sound insulation. In addition to this a spatial acoustics concept was drawn up for the office areas. The energy concept is notable for the particularly high level of thermal insulation and the reuse of the heat recovered from the production and testing areas, all of which results in a shortfall vis-à-vis EnEV requirements of up to 30%.
