2017 Race to Zero Competition Jurors

You are here

The Race to Zero Student Design Competition (Race to Zero) inspires collegiate students to become the next generation of building science professionals through a design challenge for zero energy ready homes. Each of the four Race to Zero contests is judged by a panel of jurors, and the first place winner in each category presents their project to a grand jury, which then selects a grand winner. Learn more about the individual jurors by contest below, or learn how the jurors evaluate projects in the Race to Zero Student Design Competition Guide

Tedd Benson
Tedd, founder of Bensonwood (1973) and Unity Homes (2012), has devoted his life to developing a better way to build. A key figure in the revival of timber framing in America, he was one of the founders of the Timber Framers Guild of North America (1984) and authored four books on the subject. Tedd launched Bensonwood to demonstrate how we can consistently build beautiful, durable, energy-efficient homes by embedding the process with disciplined craftsmanship, in combination with advanced technology and contemporary manufacturing efficiency. After having spent time many years with the Bensonwood team developing processes, systems, logistics, and technology, Tedd went on to found Unity Homes with the objective to make high-performance homes affordable and normal. Tedd is a nationally known speaker and presenter and is the recipient of many awards, including an honorary doctorate from Unity College, and most recently, the Granite State Award in recognition of his statewide and national influence on best building practices.

Bilal Daher
As an Associate at Studio Completiva, Bilal Daher has shown his ability to comfortably shift roles as project designer to job captain in charge of construction documents and proper coordination with all consultants. His road to Colorado is one less traveled. Born in Dublin, Ireland, and raised in Fort Lauderdale, Florida, via London, England, Bilal has used the exposure to different urban environments as a tool to understanding design and the effects it can have on communities. After studying at the University of Colorado, the decision to remain in the Denver metro area was directly related to scale. Bilal quickly recognized that Denver’s new growth offered the opportunity to collaborate and design not only within the scope of a building but at a masterplan scale. This outside-in approach has driven his design narrative to tell a story not only about a building or project but a community.
