sustainable replacement construction of an office building

Intro

This replacement construction with nZEB and BREEAM Excellent qualifications is on the corner of Avenue des Arts, one of the defining boulevards in Brussels. With the facades looking out on different streets, their approach and design is distinctly different, with a considerable contribution of VK's facade engineers. The whole of materials, transport and processes needed to construct, and deconstruct this building, was analyzed from "cradle to grave".

Story

The whole of materials, transport and processes necessary to construct (and deconstruct) the building, was analyzed from “cradle to grave”.

The building on Avenue des Arts 19 in Brussels was replaced by a new building designed by POLO Architects. VK was responsible for all the engineering such as structural and M&E engineering, but also façade engineering, energy reporting, BREEAM, and acoustical engineering. The project was designed and realised with BIM.

Differentiated approach

As the two main façades of the building border on two different streets, they are also addressed differently. The south-facing façade on the Joseph II street uses horizontal fins as sun blinds. At the same time, the façade becomes more introvert. On the other side, the façade opens itself along the small ring around Brussels. Metal braided curtains provide the necessary shading. A nice challenge for our façade engineering department.

nZEB & BREEAM Excellent

The new building is a passive office building that complies with the nZEB performance criteria and achieves a BREEAM Excellent rating. VK carried out a design stage assessment that resulted in a BREEAM Excellent certificate. To limit energy demand, the design of the building included many passive measures and the offices are equipped with open climate ceilings that allow for low-temperature heating and high-temperature cooling. In combination with night ventilation, the mass of the building is also integrated into the energy concept. To provide a sustainable energy source, photovoltaic solar panels are implemented in the project.

The energy consumption and thereby the environmental impact of new buildings has strongly decreased over the last decade. For this project, the whole of materials, transport and processes necessary to construct (and deconstruct) a building, was analyzed from “cradle to grave”.
