Nagelmackers moves into a flagship green building of Nextensa and ION

Nagelmackers is celebrating its 275th anniversary by moving into Monteco, the brand new state-of-the-art office building built by Nextensa in joint-venture with ION, renowned developers of sustainable and quality real estate. The name of the building is a contraction of the word 'Montoyer' (a reference to the street where the building is located) and the word 'ecological'. A logical combination of the "best of both worlds" in terms of location and sustainability.

Nagelmackers, Nextensa and ION announce the commissioning of Monteco, a brand new 'fossil fuel free' office building in the European Quarter that meets the high quality standards of renowned property developers Nextensa and ION. The real estate players strive to build a portfolio of only high-quality properties that meet the highest standards of architecture and sustainability. The move to the new headquarters of Bank Nagelmackers is perfectly in line with its image as a personal and private bank. Archi2000, Monteco's architect, opted for a unique concept in the heart of Brussels, which is characterised by the combination of a sustainable wood-frame construction and the use of intelligent technology. A truly state-of-the-art building, in other words!

"As a real estate developer, in addition to innovation and architecture, we are strongly committed to CO2 reduction and compensation. Building with wood has a double advantage in this respect: on the one hand, less CO2 is released into the air as compared to the production of concrete, and on the other hand, large amounts of CO2 are absorbed by the trees used in the construction, which are replaced by new plantations," explains Alexis Spaas, Business Unit Manager Brabant at ION.

Dreaming about a green future

"Nagelmackers has been committed to greening its product range for several years. Since 2019, this has gained momentum with the signing of the UNPRI (United Nations Principles for Responsible Investment). The bank is also making great strides in relation to the SFDR (Sustainable Finance Disclosure Regulation). Most of the funds in its range, managed internally and selected externally, will be at least category 8 funds, which means they can be considered sustainable funds," explains Yves Van Laecke, COO of Nagelmackers.

A great architectural achievement

The wood used for the new Nagelmackers headquarters is PEFC certified and comes from a maximum radius of 500 km from the site. This is a beneficial situation.

"Heat pumps and solar panels have been installed, contributing to the heating and cooling needs. The large windows throughout the building provide wonderful light and a pleasant working environment. They are high from floor to ceiling, some three metres high, which gives a great impression of space," explains Olivier Vuylsteke, CIO of Nextensa.

This intelligent technology will reduce energy consumption, especially as the BMS system monitors temperature, humidity, ventilation, etc. Automatically reading water and electricity meters immediately detect any leakage.

A committed approach

The sustainability certificate that every sustainable building wants is the BREEAM certificate. This is an abbreviation for Building Research Establishment Environmental Assessment Method. This label aims for sustainability without loss of comfort, safety or health.

"MONTECO is aiming for BREEAM Excellent certification, taking into account ten or so sustainability criteria. This is a high level in BREEAM certification. First of all, there is the design phase, for which we have obtained no less than 77%, whereas the standard to be achieved is 70%. Now there is the final post-construction phase. We are convinced that we will obtain this label by 2023," explained Michel Van Geyte, CEO of Nextensa.

"The customers have not been forgotten, of course! Nagelmackers will soon receive them at the Monteco agency in discreet but comfortable consultation rooms, equipped with modern audiovisual material, so that the bank can offer them personalised services on the spot and at a distance. In addition, all the equipment that is still in good condition deserves a second life and has been donated to charities and associations," concludes Dirk Huybrecht, Head of Marketing and Communication at Nagelmackers.
