WoodXZip, Wood Construction before Prefabrication

Reference number
Coordinator ZENERGY AB
Funding from Vinnova SEK 300 000
Project duration October 2017 - May 2019
Status Completed

Purpose and goal

In order to evaluate the hygrothermal performance of the WoodXZIP wall, the following was carried out in this project: 1.Design of the WoodXZIP wall system. - 100% achieved 2.Production of the mock-up of a WoodXZIP wall. - 100% achieved 3.Measurement of the hygrothermal performance in the real world at HSB Living Lab. - 100% achieved 4.Simulation of the hygrothermal behaviour of the wall and validation of the model by the measurement results. - 100% achieved 5.Simulation the moisture safety of the wall under various climatic conditions in Sweden. - 100% achieved

Expected results and effects

The comparison between the real-life measurements and calculations showed very good accuracy of the simulation. Therefore the model was further applied to the feasibility study under various climatic conditions of Sweden. It was shown that inside of the wall does not have a moisture risk due to the accumulation of moisture under the climate of Gothenburg, Lund, Stockholm, Karlstad and Luleå. Therefore is it concluded that the wall can be used in Sweden widely with no moisture risk.

Planned approach and implementation

In the next step, the development of the technology should focus on the cost-effectiveness and design of all the construction details. Once these are proven to be competitive against conventional solutions, the WoodXZIP system shall be ready to be applied in the market.
