New Building Certification

MAHÜ 77 (former Generali Center), A

The project involves the remodeling and refurbishment of a multifunctional complex with offices and a shopping center dating from 1974 and 1991. The area of the former mall, which was dominated by small shops, is being converted into large shops on three separate levels with a total lettable area of around 7,800 qm. The traditional building in Vienna’s bustling Mariahilferstraße will receive a two-story modern glass facade.

The design envisages the complete elimination of the existing mall. The openings in the ceiling of the mall are also being closed and the escalators removed as a way of significantly increasing the retail space. The pedestrian zone of the extremely busy and urban Mariahilferstraße will itself become the mall, with the sales areas being directly accessible from the street. The three new entrances are clearly legible on the façade and are lent extra dynamism by generous two-story voids. This will create separate shop levels at ground and first floor levels (both for fashion) and in the first basement (a supermarket). Alterations will also be carried out at second floor level (offices) in order to improve the use of space. Finally, the modernization of the building services plant during the ongoing operation of the offices will represent a particular challenge for the integrated design process.

ATP sustain was commissioned to provide consultancy services in connection with BREEAM certification. These included sustainability advice and the evaluation of the areas of construction management, health and comfort, energy, mobility, water, materials, recycling, ecology and environment. Key engineering services included a lifecycle cost calculation and energy optimization, an energy audit, a study of low emission technologies and the ecological improvement of the green areas. Steps to optimize energy efficiency included the replacement of building services components and the complete reconstruction and adaptation of the roof in line with current insulation standards, followed by an extensive program of rooftop planting.
