Housing Authority (TNHA)
What is the TNHA Sustainable Housing Project?
In order to address the critical need for affordable, sustainable, energy efficient, "green" shelter, the Cold Climate Housing Research Center (CCHRC), in partnership with the Tagiugmiullu Nunamiullu Housing Authority (TNHA) has designed a Sustainable Home that:
There have been many generations (TNHA-SH I Anaktuvuk Pass 2008; TNHA-SH II Atqasuk 2011; TNHA-SH III Atqasuk and Point Lay 2010-2011; TNHA-SH IV Kaktovik-Point Lay-Anaktuvuk Pass 2013-14; TNHA-SH V Nuiqsut-Wainwright-Atqasuk 2014) each improving on and building on experience with the prior generation of the award-winning (HUD 2010 Greener Homes Sustainability Award) TNHA Sustainable Housing Project. Each design generation also incorporates new and emerging technologies. The TNHA-SH III, IV and V designs create a super-insulated house with a monolithic envelope that slashes fuel use and incorporates innovative features such as an adjustable, portable foundation designed to respond to unstable ground, solar hot water collection, and integrated heating and ventilation.
These homes should not be seen as “the answer” but simply as one very promising approach to the challenges faced in our North Slope communities and, perhaps, elsewhere. The ultimate outcome may be reduced energy usage, sustainability, or improved useful life. Reduced cost may be an outcome; but it is not the absolute goal. TNHA-SH is exciting and innovative, and to that end, TNHA is committed to the construction of 30 homes by December 2014. However, application of the TNHA-SH concept remains very much a work in process, constantly changing and evolving as a consequence of lessons learned along the way.
