GrAB, or Green Arctic Buildings project, is progressing with its activities related to green construction technologies with their partners in the Russian Federation.
Arctic Cluster partners will establish 2 similar and fully equal pilot objects in Murmansk and Petrozavodsk (small-scale buildings 8x8 m) which will include measures for demonstrations and applications; renewable energy sources installation and maintenance; classroom facilities to demonstrate energy savings and building envelope efficiencies.
The pilot objects in Murmansk and Petrozavodsk will be made with the same design and made of the same material, which would allow to see and to assess how the same construction materials and solutions (foundations, frames, exterior finishes, plumbing, appliances, insulation, ventilation, windows, finishes, and flooring) are functioning in various climate conditions. The pilot projects will also be working as a laboratory for innovations and developments in green building technology, testing new technologies and measuring performance in the territories of High North (Murmansk) and adjoining territories (Petrozavodsk, Republic of Karelia).
Comparative scientific data
Equipped with the sensors, meters, temperature-sensitive elements, the pilot objects will provide comparative scientific data on the energy (saving) performance of the construction and insulation materials, technical solutions utilized. According to GrAB Project Leader, Professor Bjørn R Sørensen, the comparison will enable the project partners to accurately evaluate energy efficiency performance before and after energy saving campaigns and retrofit interventions. Also, the performance of various insulation materials will be measured and compared in various weather conditions.
Aside from the scientific value of the comparative studies, the pilot objects would be utilized as the facilities for teaching purposes. A combination of classroom instruction with on-site training, using the facilities of newly-created pilot objects focusing on green materials and renewable energy sources, will increase the academic quality of teaching, and will lead to an increase of students’ achievements. Also, the pilot objects could be utilized as the places to run joint training events, summer camps for students learning of green technologies from the counties of the Barents region.
What will be the main aspects to be monitored?
- Different wall constructions in two different rooms: frame wall, timbered wall and log wall with insulation according to passive house standard.
- Different wall elements to compare characteristic measures.
- Temperature, humidity, moisture and energy consumption to compare reality to the standards and simulation models.
- Indoor air quality by measuring VOC and CO2 levels.
GrAB partners will calculate energy efficiency according to the different standards and guidelines in the Kolartic countries
. Furthermore, they will compare the results between the two pilot houses and,
possibly, with some already existing houses.
