Ecological and economic flagship project in Denmark

Super Spacer® installed in the BaseCamp Lyngby

Affordable architecture is one of the most pressing concerns of our time.

However, the issues of sustainability, energy efficiency, land sealing, recycling

management, comfort and social integration are contrary to the economic

demands. Lars Gitz Architects and BaseCamp Student pulled off the remarkable

feat of combining these complex requirements within a spectacular, multi-award-

winning student residence. Serial, modular construction, low-cost, recyclable

facade materials, renewable energies and near-natural building greenery and

seepage areas were the key to success here. One of Scandinavia's leading glass

processors, Glaseksperten A/S, has contributed towards the realisation of the

ambitious building concept of the BaseCamp Lyngby on several occasions:

Automated production of the insulating glass units, varying direction-dependent

glass construction and use of the warm edge spacer system Super Spacer® T-

SpacerTM Premium Plus.

Record-breakingly fast, sustainable and economical

The running track on the roof of Google's new European headquarters in London

will be used for the first time in 3 to 4 years at the earliest. The residents of

BaseCamp Lyngby, built on a 41,000 square metre site, were able to don their

running shoes as early as August 2020: a park landscape was created on the

green roof of the extensive student residence complex in northern Copenhagen

using a system of biodiverse planting, urban gardening areas and an 800-metre-

long path that can be used for walking or jogging as you please. From the flat

terrain, it winds its way up six storeys above the organically shaped building back

down to the starting point while enclosing cosy inner courtyards and a circular

community centre in the process. The facades are reminiscent of tall trees and

forests by virtue of the vertical arrangement of the panels in three different

shades of oak wood as well as the line of windows, and in just the same way as

the entire complex they blend harmoniously within the surrounding nature. The

project developer, BaseCamp Student Nordics, a part of the Europe-wide

BaseCamp Group, deliberately wanted to give something back to Lyngby

Municipality and enter into dialogue on social and environmental aspects. The roof

is therefore open to the public to provide meeting areas.

The construction time for a project of this size is impressive. The 786 flats,

including 639 student flats and 48 senior flats, were completed near Lyngby

University of Technology within the space of two and a half years. The building

was also intended to be no less spectacular, but one aspect distinguishes

BaseCamp Lyngby from many other major projects: Ecology and economy

determined the architectural concept equally.

Modules as the basis of architectural aesthetics

In order to meet the estimated construction costs of around € 75 million the

Danish firm of 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 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 facades 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 facade one of the pillars of the

sustainability concept, which has been awarded BREEAM Very Good certificate

(equivalent to the DGNB certificate in silver). 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 windows with warm edge spacers

The aluminium windows with triple glazing also form part of the overall concept.

As is so often the case in Scandinavian architecture, the BaseCamp studios and

communal areas are glazed down to floor level to allow as much daylight as

possible into the room even during the winter. The Danish insulating glass

manufacturer Glaseksperten supplied 4,000 insulating glass units packaged in

sizes of up 4.011 x 1.127 metres 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-SpacerTM Premium Plus in various widths as the warm edge spacer

system. Sales Manager Jesper Hønning declared: "An ever increasing number of

our customers wish to install energy-efficient windows. We consistently use low-

emission thermal insulation glass and solar control glass combined with non-metal

warm edge spacers in order to avoid thermal bridges and optimise the heat

transfer coefficient.” At the company's headquarters in Hjørring, an ultramodern,

automated IG line is available for the production of insulating glazing for sizes of

up to 3.2 x 6 metres. "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 went on to say, "the fully automated

continuous application of spacer from the reel saves time and money and

guarantees top class product quality that is reproducible.” Joachim Stoss,

Managing Director of Edgetech Europe GmbH and Vice President International

Sales at Quanex added: "Northern Europe is a global pioneer in the field of

climate protection and therefore one of the growth markets for warm edge

products. Of course, we are extremely proud that our Super Spacer system has

been installed in another Scandinavian flagship project".

About Edgetech Europe GmbH

Edgetech’s Super Spacer® flexible foam-based spacer systems acts as energy-

efficient warm edge spacers in insulating glass windows. They significantly reduce

energy loss to the outside, largely prevent condensation and also contribute to the

lifetime of a window. On average, worldwide, more than 300 million metres are

sold annually in over 100 countries.

Edgetech Europe GmbH, located in Heinsberg Germany, is a fully-owned

subsidiary of Quanex Building Products Corporation, an industry-leading

manufacturer of components sold to Original Equipment Manufacturers (OEMs) in

the building products industry. Quanex designs and produces energy-efficient

fenestration products in addition to kitchen and bath cabinet components, with its

head offices in Houston, Texas. Based on turnover Edgetech/Quanex is the

world‘s largest manufacturer of spacers. Edgetech Europe GmbH is a sales

location for the markets in continental Europe and one of the three worldwide
