UBS bank headquarters, first BD2M project

1 July 2020 - 11h08

A BDM-BD2M (Sustainable Mediterranean Buildings of Monaco) commission was held yesterday morning in the form of a webinar. Annabelle Jaeger-Seydoux, director of the Mission for the Energy Transition (MTE) or members of the commission and of EnvirobatBDM, punctuated the morning during which the first BD2M project was notably presented in the design phase. This is the headquarters of UBS bank within Villa Belgica, located at 2, Avenue de Grande Bretagne.

Just a year ago, the public discovered the Villa Troglodyte, the Principality’s first building certified “Sustainable Mediterranean Buildings” gold level, the highest distinction. A pioneer in energy performance, this construction by J.B. Pastor & Fils had laid the groundwork for a new era for the sector and local professionals. “It launched BDM factually in Monaco,” said Annabelle Jaeger-Seydoux. In September 2019, the approach was thus adapted to the local context and situation with the launch of its Monegasque version BD2M, as indicated by the director of the MTE in the introduction. Before mentioning the government’s energy objectives, which are in line with the commitments of the Livre Blanc, in particular with carbon neutrality for 2050, buildings currently alone represent 30% of the greenhouse gas emissions of the Principality.

BDM and BD2M, a “global approach”

Arthur Goubet, member of EnvirobatBDM insisted on his side on “the global approach” of this process which endeavors to evaluate a project on three phases: design, realization and use. He also recalled that “the idea of ​​these commissions was to make them mini-trainings in order to raise the skills of professionals, projects and the sector in general” and this in “benevolence”. The evaluation principles are based on seven main themes: project management, territory and site, materials, energy, water, comfort and health as well as social and economy. Then, he gave the floor to the speakers of GB2-UBS, a tertiary rehabilitation and elevation project which is to host the bank’s headquarters in Villa Belgica.

Villa Belgica as an example

This 1400sqm project by the UBS contracting authority and Michel Pastor Group for the delegated contracting authority (Greenaffair is the Environment IT Project Management Support), the design of which was entrusted to the architectural firms of Jean Nouvel and Alexis Blanchi, had to meet several challenges. “There was a strong desire to respect environmental criteria while preserving the historic facade of Villa Belgica,” said Monegasque architect Alexis Blanchi. The particularity of this project resided in the reinforcement of its solar protections with different screen densities according to the sunshine or even the use of bio-based materials among which the choice of a rice straw insulation, the re-use of terrazzo but also recycled carpet. For the lighting part, in addition to the LEDs generalized throughout the building, energy production will be ensured by an installation of 41 photovoltaic panels on its roof. “Monaco is setting the bar very high,” said Patrick Sauvage, chairman of the digital commission, for this project. Work on the latter must begin next December for a delivery announced at the end of 2022.
