Wood for Zero



Our project

NERO develops and demonstrates technical solutions, which significantly reduce the costs of new nearly Zero-Energy Wooden Buildings and districts compared to the current situation.

On site and nearby renewable energy system solutions are studied in order to provide real addition of renewable energy production and to provide solutions, which are optimal on local grid and energy system level.



According to Article 9 of the Energy Performance Buildings Directive (EPBD), Member States shall ensure that all new public buildings in Finland are Nearly Zero-Energy Buildings (nZEB) since start of 2018. After public sector reform, the law is going to be expanded elsewhere: all new buildings must be built by Article 9 in 2021.

Integrating renewable energy production elements into nZEB in cooperation with construction industry's design and procurement process is a major challenge. Even if progress is slower than expected, we are sure that the development of nZEB products will increase demand in market as consumers are more aware of cost reduction solutions.


In Nordic countries, wood has been traditional building material over centuries. The use of timber in the North derives from material availability, economy and user-friendliness in construction. The real secret behind timber’s success is its adaptability: wooden buildings have standed well in exceptional climate conditions, which include relatively cool and a slightly humid environment.

During strong urbanization in 1960’s the construction of wooden houses collapsed significantly. The popularity of wood has never been lost, but lack of use may have led to disappearance of inherited knowledge of wood material. In addition, we started to build houses from concrete elements by the mass production.

Today, climate change and environmental consciousness have increased need for sustainable construction. By modern methods, apartment buildings and public buildings are going to be built more often as wooden framed ones. As our total energy consumption have to be lowered by 40%, new industrial processes, materials and renewable energy sources must be developed.

In order to accelerate this positive advance, our NERO -project develops and demonstrates nearly Zero-Energy (nZEB) Wooden Buildings design process and procurement models with reduced cost for large-scale use in the northern climatic conditions and on performance level of nearly zero and beyond. Demonstration tasks on net-zero and energy-plus level will be also executed in the project.
