BUILDING USAGE 17
JAMB Architects is proud to present a deeply innovative high rise mixed use building that will serve as a hub of activity for the Technical University of Denmark, and push the boundaries of office construction in Denmark It will offer a high end work environment and facilities for private sector partners who require proximity to the technical university and its world class research We propose a 17-floor timber high-rise office building, the first of its kind in Denmark.
The tower is a visual focal point for the campus with its iconic SkyBar, but is scaled appropriately to its surroundings, respecting the character of the campus and limiting its shading impact to the area. The podium of the building, which occupies the lower three levels, offers ample common space for members of the public, students and building tenants to interact with one another By accommodating easy movement along the principal North South axis,
The building integrates its public space into the fabric of the campus. The building also houses all the occupants' transportation needs with an underground parking for cars and bicycles, also connected to this central axis, ensuring a highly efficient use of the space.
The building is designed for rapid construction using sustainably sourced Scandinavia timber which is assembled in an innovative modular construction system for a low embodied energy and carbon footprint Through this, and a healthy indoor environment, we aim for a DGNB Platinum certification.

SITE LOCATION
For this project, we wanted to push the limits of what was possible in a sustainable high-rise building. This begins with the embodied CO2 of the structure, continues with the energy performance of the envelope and concludes with buildings end of life. Our design addressed all three phases of the building life from its inception by specifying a high-performance envelope, a modular timber construction, and assembly methods that use mechanical fastening and pre fabrication where possible This was an ambitious goal for many on the team who wanted to study the feasibility of constructing such a large project out of timber Tight integration between teams enabled us to find the solutions to make this project a success.
Working with wood was a primary design constraint which shaped the building into what you see We immediately realized we would be working with shorter spans, a narrower floor plate and very stringent fire safety and evacuation requirements which we integrated into the design from day 1.
One of the great challenges of the site was the need to fit a large office building onto a relatively small site footprint in a way that was appropriate to its surroundings. It became apparent that a building occupying the entire site would cast significant shadows on the adjacent building 310 and the central courtyard, compromising their access to daylight Furthermore, the lower storey offices of our building would have insufficient lighting levels. We experimented with a range of layouts but found that the optimal layout would require pushing the facade away from the Eastern edge of the site and angling the Eastern facade toward the South to enable daylight autonomy throughout the entire height (→ see massing study, right)
← One central goal for the building was to be well connected We knew that many of the students would be coming to the building from the North and South of the site, so the North South axis between the existing building 310 and ours had to be preserved. We positioned the Cafe along this central thoroughfare and ensured facilities such as the central courtyard and the car and bicycle parking were connected to this axis. In fact, all high usage facilities are located in the pedestal for easy access to students and members of the public.
A modular wooden high rise for DTU Campus
With the envelope of building 313 we wanted the spaces and materials to celebrate the core material: wood.
The high rise was to evoke the verticality of a forest: The organic shapes of the vertical shading fins which are made of folded perforated steel panels creates a dynamic façade which draws the eyes upward Their white color reflects a diffuse light into the interior The ground floor atrium uses the warm colors of wood, the massive columns and the irregular everchanging light filtering through the green wall to create an inviting calm space, reminiscent of a forest floor. Throughout the building’s interior and exterior the ubiquitous presence of plants freshens the air and lightens the atmosphere in the public spaces.
The floors and exterior walls of the building use slate and more earthy colours for a natural aesthetic

The façade panel was one of the most challenging elements of the building We wanted to develop a system which offered excellent thermal performance and comfort and was ready for rapid construction We opted for modular factory assembled panels inspired by Kingspan QuadCore Karrier System with exceptional water and airtightness characteristics, all mechanical fastening and a light construction with a low environmental impact It also exhibits low linear losses as the insulation is continuous at the joints.
One goal was to reduce or eliminate hard foam insulation because of its flammability and negative environmental impact We opted for Rockwool sandwich panels as the material is highly recyclable and has excellent thermal and fire characteristics. The panel system mounts rapidly onto the external façade and seals mechanically using interlocking joints, without the need for application of sealants or tape. This enables deconstruction and recycling of the panel system at the end of life, substantially reducing its environmental impact
The developed panel system is optimized for fast construction on site and easy factory assembly Every material has been selected for recyclability and a low CO2 footprint Krone brand PassivHaus certified Danish windows were selected These have an exceptionally low u value, a low emissivity coating and very low linear losses, which is important as the building has a high glazing percentage to ensure daylight autonomy in the office.
The fiber cement panels were selected for their finish, durability and fire resistance. They also have a lower CO2 footprint that steel or aluminum panel

An optimized shading strategy was crucial to reducing the cooling load during the summer as there is a high percentage of glazing Our initial concepts explored various passive and active means of shading, including pivoting vertical fins, sliding panels, and a deployable tensile fabric Based on modelling of the building, it was found that active shading had only a marginal advantage as compared to the passive means envisioned In addition, durability concerns related to motorized shades in the higher wind speeds 70 meters above ground and the cost and complexity of implementing such a system was not justified by the marginal gains. The vertical fins we have developed are made of a folded perforated-steel sheet. The organic form has a complex geometry which is easy to manufacture and assemble using modern digital manufacturing techniques The shades are angled optimally for each façade
For the South façade, the vertical fins remain for aesthetic and continuity reason Microshade window glazing has been selected to shade the façade This innovative bespoke solution cuts high angle solar radiation in the summer and allows low angle solar gains in the winter months. It works similarly to a horizontal louver system, but with lower installation costs.
Pedestal shading was an excellent example of how the synthesis of various design requirements worked to create innovative and beautiful solutions Because of the large spans and loading consideration particular to our structure we could not place the 200 person auditorium in the lower levels of the pedestal It became apparent early in the design process that the auditorium placed on the second floor would need additional evacuation routes to enable the large capacity We solved this by adding an external staircase that wrapped around the South and Western façade This offered the opportunity to shelter pedestrians accessing the main entrance with the help of a large green wall. This living wall, which follows the line of the staircase, offers seasonal shading to the largely glazed pedestal. It also creates a perfect framing of the main entrance and creates an inviting feeling of shelter and enclosure by exploiting the architectural concept of compression and release Inside the Atrium, the dappled light filtering through the living wall is reminiscent of a forest canopy
↑ The iconic green façade connects the building thematically to its core material: Wood
→ Vertical shades cover the large East and West facades. Inspired by architect Kengo Kuma’s sculptural shapes, the vertical shades create a complex geometry which is easy to manufacture and install

Another example of tight collaboration that yielded a mature design early in the process was the floor plate of the tower This tower was designed for rapid construction using modular assembly We understood early the unique challenges of working with wood, which has shorter spans and has neither the stiffness and compressive strength of concrete nor the tensile strength of structural steel Modular construction is also at it’s best when the structure, envelope and interior layout are closely integrated
The economics of the high rise were also accounted for in the slab thickness We collaborated with the MEP, fire and structure team to create the thinnest floor slab. By optimizing this, we were able to reduce the floor to floor height to 3.86m from 4.0m, while keeping an optimal 3.0m clear height in the offices this small change added 2 floors of offices, which meant more revenue for the client
▪ need to maximize rentable floor area
▪ layout of the offices and circulation routes to maximize floor plate efficiency
▪ lighting levels required for each space
▪ sizing of the stairs, elevators and MEP shafts
▪ longest allowable distance to the nearest fire escape (<25m)
▪ The required stiffness of the core
▪ need to minimize CO2 footprint of the concrete core
▪ maximum span of the beams
The size and position of the windows was optimized to maximize daylight autonomy and reduce the glazing percentage We found that increasing height of the window off the ground had a more beneficial effect on daylight penetration into the spaces than the window width, that window area below the desk height had no discernible benefit for lighting, and that fewer and larger windows reduced the amount of linear losses, thus improving energy performance. These changes had significant incremental benefits that positively impacted energy and lighting levels.
↑ Daylight autonomy was a deciding factor in how the tower evolved into its characteristic wedge shaped. The building responds to its surroundings.
→ To further increase the height, the suspended ceiling was offset as far as possible from façade and the window placed further off the floor.
