Quanex Wins 2021 Best Green Project for Flagship Project in Denmark

Affordable architecture is a pressing concern around the world. However, the issues of sustainability, energy efficiency, land sealing, recycling management, comfort and social integration can sometimes be thought at odds with cost-effective construction.

BaseCamp Lyngby, a major new living complex to house students at the Technical University of Denmark, pulled off the remarkable feat of combining these complex requirements within a spectacular, multi-award-winning student residence. Serial, modular construction, low-cost, recyclable façade materials, renewable energies and near-natural building greenery and seepage areas were the key to success here, as was the use of Quanex’s warm edge spacer system, Super Spacer® T-Spacer™ Premium Plus.

The project recently was named the winner of Glass Magazine’s Best Green Project for 2021. Here’s how the architect firm Lars Gitz Architects, glass processor Glaseksperten A/S and Quanex worked together to ensure the project was a success.

A Modular Approach

To meet the estimated construction costs of around €75 million, Lars Gitz Architects designed a trapezoidal module that is repeatedly rotated by 180° and stacked at different heights to create the gently rounded structure. The building’s outer skin also constitutes a model example of cost-efficient construction. The ventilated curtain wall is insulated with rock wool and clad with slabs made of pressed volcanic basalt rock from Rockpanel. With a weight of 8.4 kg per m2, the extremely light material can be cut to size on-site and simply attached to the substructure.

The façade’s panels with their natural wood look almost entirely consist of natural volcanic rock and recycled rock wool and can be repeatedly reused in line with the idea of a circular economy. This makes the façade one of the pillars of the sustainability concept. The energy-saving green roof with the photovoltaic modules serves as a form of thermal insulation, an energy provider and natural air conditioning. The rainwater that is captured is returned to the natural water cycle via evaporation, which consequently relieves the burden on the sewage system and lowers the ambient temperature.

Energy-Efficient Glass

As is so often the case in Scandinavian architecture, the BaseCamp apartments and communal areas are glazed down to floor level to allow as much daylight as possible into the room, even during the winter.

Glaseksperten supplied 4,000 insulating glass units packaged in sizes of up 4.011 x 1.127 meters to the construction site in accordance with a meticulous logistics plan. Due to the organic shape of the building, the glass structures change according to the direction. Depending on the heat input and amount of light, solar control glass, thermal insulation glass or clear glass with varying coatings and glass thicknesses were used. Glaseksperten opted for Super Spacer® T-Spacer™ Premium Plus in various widths as the warm-edge spacer system.

“An ever-increasing number of our customers wish to install energy-efficient windows,” said Glaseksperten Sales Manager Jesper Hønning. “We consistently use low-emission thermal insulation glass and solar control glass combined with nonmetal warm-edge spacers in order to avoid thermal bridges and optimize the heat transfer coefficient.”

At the company’s headquarters in Hjørring, an ultramodern, automated insulating glass line is available to produce insulating glazing for sizes of up to 3.2 x 6 meters. “Super Spacer is of key importance to Glaseksperten in supplying quality products, which also ensure we are a leading company in economical and ecological terms,” Hønning added. “The fully automated continuous application of spacer from the reel saves time and money and guarantees top-class product quality that is reproducible.”

“Northern Europe is a global pioneer in the field of climate protection and therefore one of the growth markets for warm edge products,” said Joachim Stoss, managing director of Edgetech Europe GmbH and vice president, International Sales, at Quanex. “Of course, we are extremely proud that our Super Spacer system has been installed in another Scandinavian flagship project.”
