University of Maryland developed cooling wood

Modern Roofing

Unusual wood experiences were conducted at the University of Maryland. A group of scientists led by Hu Liangbin created a fundamentally new material based on wood. Researchers removed from her leagues no n – is a special component of the cell walls of trees. The residue is predominantly cellulose. 

This connection is able to absorb infrared light only at a very low level. In addition, cellulose reflects the visible part of the light spectrum. As a result, wood processed by scientists sends back into the environment most of the heat generated by sunlight. Using this property, scientists suggest building special self-cooling houses.

Hu Lianbin notes that wood without lignin is also capable of capturing heat, which is radiated in the room itself in a different wavelength range. If it becomes cooler later, the material returns this heat to the environment.

Scientists have already conducted experiments and calculated that special wood in an ordinary American household can save from 20 to 35% of energy.
