Building Information Modeling/ Virtual Design & Construction
A triangular building that shimmers like a gemstone will be the first thing that travelers see as their train rolls into Uppsala. “Juvelen” (the Jewel) is the name of Uppsala’s new landmark and is scheduled for completion by late 2016.
In collaboration with the Utopia architectural firm, Skanska won the land-use competition organized by the City of Uppsala and thereby secured the assignment to construct this spectacular building. Juvelen also won the reader’s contest arranged by Uppsala Nya Tidning.
The City’s architectural demands are high: the building is to provide a dignified entrance to Uppsala. Since sustainability is also a key concern for the City, the office building is also to be a positive energy building and generate more energy than it consumes on an annual basis.
We have taken this assignment seriously, and this project will be Skanska’s greenest-ever. The project has achieved LEED pre-certification at the Platinum level. Our aim is that Juvelen will be the most sustainable office building in the Nordic region. The building will be six-floors high and comprise some 10,000 square meters.
Skanska will take sustainability efforts one step further by offering future tenants training, with the goal that their businesses will also become LEED-certified.A planned bike center on the first floor will also enable Uppsala residents to benefit from Juvelen’s sustainability efforts. Cyclists will be able to park their bikes in the center, hang up their wet clothes and take a shower before continuing their journey by train.
Metal cartridges and light strings will give the building a golden shimmer. The choice of architects fell on Utopia due to the firm’s ability to achieve innovative architecture combined with a sensitivity for the construction process. Fredrik Hjortzén, Business Developer, says:
“Utopia takes a bold approach and works with the integration of sustainable solutions and, most importantly, understands what is technically feasible. For us, the realization of our competition entry is essential.”
A project group comprising architects, consulting engineers, sustainability experts, business developers and subcontractors has worked together to produce the final plan. Close collaboration has led to intelligent energy, environmental and architectural solutions.
The groundbreaking ceremony is planned for the first quarter of 2015.

Juvelen will be Skanska’s most sustainable building to date. A “dark-green” project – Skanska’s greenest level – which means that both the construction process and the end-product have virtually no negative environmental impact.
The project has earned LEED pre-certification at the Platinum level. The building has been assessed according to several categories, choice of materials, indoor climate, energy performance, water efficiency and site. Our aim is that Juvelen will be the most sustainable building in the Nordic region, and the second-most sustainable office building in the world.
The City of Uppsala works actively with sustainability and wanted to commission a positive energy building, which means that the building would generate more energy than it consumes on an annual basis. This requirement challenged the project group to think really hard about energy solutions.
Solar panels covering an area of almost eight tennis courts will be integrated with the facade. The building will be connected to the district heating system, and surplus energy from the solar panels will be sold to the electricity grid in summer, while extra energy is purchased in winter.
A positive energy building requires a sealed thermal envelope. The inner façade, a dense core of concrete, will be clad with a lighter facade. Besides being decorative and providing a surface for mounting the solar panels, the external façade will also provide protection from the sum. Office buildings with lots of glass are often too hot during thesummer, but we have consciously adapted the window area, angles and depth of the metal cartridges on Juvelen’s façade according to cardinal directions and insolation.
Juvelen also uses Deep Green Cooling, which is Skanska Fastigheter’s patented method for cooling buildings. This is a climate system that utilizes the cooling capability of groundwater in its natural state. No energy is required for heat pumps.
During the construction process, the project will be a Green Workplace, which is Skanska’s own environmental label. It means that we recycle 100 percent of our waste, use only environmentally approved chemicals, drive work vehicles in a fuel-efficient manner and attempt to protect the environment in a variety of other ways.
The building’s sustainability attributes include environmentally friendly materials, good indoor air quality, motion-activated lighting, low-flush toilets and other solutions.
Skanska aims to involve the future tenants in sustainability efforts. We will offer all of our tenants training, with the goal of becoming LEED-certified businesses.
Many employers now understood that light-filled, open premises with good indoor air quality impact productivity and reduce sickness absence. The company’s ability to attract employees also increases.
The sustainability theme will be reflected on the entry level. Skanska hopes to attract activities with a distinct sustainability perspective. One proposal is a civic center in which the City of Uppsala can provide information about sustainability issues. Another suggestion is a bike center for Uppsala residents, where cyclists can park their bikes indoors, take a shower and freshen up before continuing on their way to work by train.
After winning a land-use competition arranged by the City of Uppsala, Skanska was assigned to construct the City’s new landmark. The City’s demands were high: distinctive architecture and sustainability. Construction is scheduled to commence in the first quarter of 2015 and the inauguration is planned for late 2016.
We will be looking for tenants in 2014. The building is attracting a great deal of interest from “green” companies, as well as companies that appreciate fine lines and architectural concepts.
Juvelen was designed by a project group comprising architects, consulting engineers, sustainability experts and sub-contractors. Anna Forsberg, the Manager of Green Business at Skanska, says:
“Collaboration with the architects at Utopia worked really well. We had very different ideas about the building at first, but after a couple of meetings and discussions, we arrived at a design that we are all really proud of. It’s a fine mix of engineering, aesthetic design and creative skill.”
Juvelen’s unique appearance is created by metal cartridges that cover the façade. In combination with light strings, the building shimmers like a gemstone. The facade is not particularly complicated, but the components must be specially ordered.
Everything behind the facade is based on a conventional and simple system. Walls and floor slabs are prefabricated, which enables a fast and cost-efficient construction process.The triangular site – the same size as the actual building – has posed a challenge. But the City has been accommodating and allowed us to lease a worksite. Steps, a plaza and bicycle parking have been planned around the outside of the building to join the different ground levels and create a welcoming and friendly outdoor space.
The project applies the Building Information Modeling (BIM) process. BIM enables intelligent information management and efficient construction processes. We design in 3D and the entire project will be visualized in BIM, which means that everyone can see the changes, that we can calculate material volumes and avoid disruptions throughout the construction process.
“We will continue to strengthen Uppsala’s labor market and promote growth by increasing the number of centrally-located office premises. Juvelen is a part of a positive trend in Uppsala and will contribute to the creation of more jobs here,” says Fredrik Ahlstedt (Moderate Party), Mayor of Uppsala.
