Wood performs based on its material properties by shrinking, expanding or warping due to the changes in relative humidity and temperature. This property intends to be utilized in architecture for purposes such as ventilation or thermal comfort. This concept was developed in the design of Ray 2, a screen that airs in dry and is resistant in humid weather. Two material options are available. Following the contemporary research, a plywood could be used performing on ‘bi-metal’ principle of different shrinkage of different wood species. In reference to the past, the tangential section applied in traditional Norwegian panelling, where different fibre density on opposite sides of the plate cause warping was proposed for the prototype. The plywood research shows better programmability. However, our paper claims that the use of solid wood, at least in the Czech context for the particular product of Ray 2, is more sustainable and therefore it is in our best interest to explore past knowledge in the field. The data from the local manufacturers, as well as from the related universities, were utilized to compare both of the cases in LCA analysis among all showing the energy savings and lower carbon emissions for solid wood.
