Jack Hébert
Chief Executive Officer/Founder

Jack Hébert is the Chief Executive Officer; and Founder of the Cold Climate Housing Research Center (CCHRC). Jack spent his early years in Alaska wintering 60 miles from an Inupiat community in the mountains of the Northwest Arctic and summers in the “old” Denali Park. His mentors and teachers were the people that thrived in these environments, the First Alaskans that lived a traditional life and the next Alaskans, homesteaders and pioneers that brought change to a timeless land. His relationship and commitment to Alaska were born from these deep roots in the “Country.” For the past 36 years, Jack has been designing and building homes as a licensed general contractor in Interior Alaska through his companies Taiga Woodcraft and Hébert Homes LLC. His homes and planned communities have created many high-quality, well-designed, environmentally appropriate, and energy-efficient buildings over a long career.

Jack is a graduate of the University of Washington, a Certified Green Professional, and is trained in LEED standards. He has received numerous honors, including the U.S. Green Building Council Cascadia Fellowship in recognition of his contributions to sustainable building, design and science; the first State of Alaska Governor's Award for Excellence in Energy Efficient Design; and the Energy Rated Homes of Alaska President’s Award. He has twice been honored as the Alaska State Homebuilder of the Year.

As an active member of National Association of Home Builders (NAHB), Jack has held many leadership roles on local, state, and national levels including the NAHB Executive Board, National Vice Chair for the 5 Northwest States, President of the Alaska State Home Building Association and State Representative for Alaska. He addressed the U.S. Senate Subcommittee on Energy on “Sustainability and Energy Efficiency in the Built Environment” and served as host and moderator of the Circumpolar Forum at the Sustainable Northern Shelter 2007. Jack has been an invited speaker at many conferences in North America and most recently in Scandinavia and Greenland. He helped raise five of Alaska’s next generation and look forward to watching their children’s children embrace a healthy, vital and sustainable future for the Circumpolar North.

Aaron Cooke
Project Manager/Architectural Designer

Aaron Cooke is an architectural designer and project manager at the Cold Climate Housing Research Center in Fairbanks Alaska.  He designs, builds, and monitors experimental prototype buildings in challenging physical environments across Alaska, and has collaborated with design groups in Russia, Canada and Antarctica to test new methods of building durable and energy-efficient homes in the circumpolar regions.  He believes that northern environmental conditions and northern culture are inseparable factors that must both be equally reflected in architecture and design in order for it to be successful.

Aaron’s university studies emphasized a specialization in rural development and Arctic responses to architectural form.  This emphasis on northern built form led him to study at the Novosibirsk State Technical University in Siberia and at the Danish International Studies Institute in Copenhagen.  He received his Masters Degree in Architecture from the University of Cincinnati and completed his thesis work as the Design Lead on the Mertarvik Evacuation Center, where he worked with the community of Newtok to develop an environmentally and culturally sustainable facility that will serve as a place of refuge as the community relocates from their current eroding site to a safer location. He was born and raised in Alaska.

Bruno C. Grunau, P.E.
Research Engineer

Bruno C. Grunau is enthusiastic about life.  He is also passionate about developing and implementing socially conscious and sustainable technologies in Alaska and the North.  Bruno joined the CCHRC team in the winter of 2011 after serving as the chief engineer for a local renewable energy firm that specializes in the design and fabrication of solar and wind energy systems.  His efforts in renewable energy system design, consultation, and project management have been applied to on-grid residential and commercial systems, as well as off-grid remote applications. His experience installing and troubleshooting energy systems in Alaska constantly reminds him of the importance of a clean, well-planned, and functional system design.  His passion for sustainable technologies began when participating on Virginia Tech’s Solar Decathlon Team in 2001.  As an engineer, he spent six years at a shock and vibration test laboratory where testing and analysis were a part of his everyday life. Though he never knew it, these experiences were leading him to his current position, where the mission of the CCHRC merges with his passion. When not at work, he can often be found making music, dancing, and playing in the backcountry of Alaska.

Corey DiRutigliano
Project Manager/Architectural Designer

Corey was born and raised in beautiful Columbus, Ohio, and moved to Fairbanks in October 2011. He found his design and building calling at an early age with Lincoln Logs, K'nex, and through a collection of involuntary lessons in home repair. He tracked these interests through to a bachelor's in Architecture at the Ohio State University, and later a master's at the University of Cincinnati. During this time he developed a passion for problem-solving and has participated in a variety of design competitions around the world. From prototype research stations in the Antarctic and homeless shelters in urban Cincinnati, to solar-powered transportation infrastructure and recyclable cardboard furniture, he enjoys challenges of every scale and type. Corey enjoys applying his knowledge of visual representation, planning, and design as much as swinging a hammer and building prototype projects. He has assured his family back home that he will be careful around bears and moose.
