Founded in 2003, Kirei produces sustainable, nontoxic materials for interior design. Their products made from either Kirei Board (wood substitute), bamboo, wheatboard, Coco (tiles made from coconut shells), woodfall (reclaimed wood) or hemp.

Kirei wheatboard is a rapidly renewable material that works as a substitute for wood medium-density fiberboard (MDF) products. Unlike wood MDF, Kirei’s wheatboard is made without added urea formaldehyde, which improves indoor air quality. Also, it is made using a minimum of 90% pre-industrial (or pre-consumer, in LEED terms) content.

The wheatboard can be used for many applications, including architectural millwork, wall coverings, retail displays, furniture, cabinetry, and flooring.

 

Since Kirei wheatboard is made from recycled, rapidly renewable and low-emitting materials, it can contribute to LEED in multiple credit categories. According to LEED for New Construction, it could contribute to the following credits:

MR Credit 4, Recycled Content: (1-2 points)
This credit requires that the project uses materials with recycled content. The calculation for percentage of recycled content is the sum of the post-consumer content plus 1/2 of the pre-consumer content. 1 point is awarded for 10% recycled content, and 2 points for 20%. The Sorghum straw contains 90% pre-consumer recycled material, contributing to this credit.

MR Credit 6, Rapidly Renewable Materials: (1 point)
This credit requires that 2.5% of the value of all building materials is “rapidly renewable”. Wheatboard is rapidly renewable since it is made with Sorghum straw, which can be harvested yearly.

IEQ Credit 4.4, Low Emitting Materials – Composite Wood:(1 point)
This credit requires that composite wood and agrifiber products do not contain urea-formaldehyde resins. Since Kirei wheatboard does not contain added urea formaldehyde, it meets this credit’s requirements.
