Juvelen, Uppsala

Sustainability and green

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.

 

Self-sufficient in energy

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 the
summer, 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.

 

A healthy building makes healthier employees

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.
