State-of-the-art zero emission building
ZEB Laboratory in Trondheim is one of the world's most sustainable buildings with documented climate accounts that show total CO2 emissions with corresponding compensation of energy production.
The office and research building has highly specialized research equipment and teaching premises where NTNU University and SINTEF Research organization will test new zero-emission technology.
Greenhouse gas emissions in the life cycle are compensated
The ZEB Laboratory will be a model project for what a building can achieve in terms of low greenhouse gas emissions. The building satisfies requirements for ZEB-COM buildings, which means that CO2 emissions from production, transport, construction site, construction of buildings, and operations, for 60 years must be compensated by energy production on the building. To reduce greenhouse gas emissions and reduce power peaks in real operation, several instruments have been incorporated into the project. The building has its own energy supply system and is connected to public electricity and the heating system on campus. Measurement and control of energy supply, air supply, lighting and solar protection combined with the number of users of the building, is handled through a separate control system. The use of artificial intelligence makes it possible to interpret the relations between indoor positioning data and indoor climate data. The laboratory itself is equipped with building-integrated solar panels and a heat pump that can use different heat sources. The estimated delivered energy consumption of the building is 38.5 kWh / m2 BRA per year, solar cells supply an annual energy production of 89 kWh / m2 BRA. Over a 60-year period, solar cell production will offset emissions from construction, materials, and the building in operation.
A signal building
The shape of the building is inspired by the shape of silicon crystals that solar panels produce. The building's facades and roof are clad with solar panels, and the roof slopes 42 degrees to the south for optimal energy production, providing the building a distinctive identity.
The new laboratory is user-cantered, where research provides answers to what is required to achieve good office and teaching working conditions in a ZEB building. This means flexibility in area design and opportunities for changes in workplace division. The ground floor is open and inviting with a canteen and presentation room closely connected to the entrance. With insight into energy production and storage of energy shown in plan 1, the building will create curiosity and become an attractive destination. The building is made with a functional structure with solid wood constructions in a flexible grid, based on appropriate spans for the building's purpose.
Interdisciplinary teamwork
The zero-emission laboratory is created by NTNU and SINTEF in collaboration with Veidekke. LINK Arkitektur is responsible for architecture, landscape architecture, and workplace design, in addition to being an energy consultant with responsibility for the climate accounts and energy concept as well as the building's future-oriented ventilation principles.
