"A team of students at the University of Calgary has designed a solar-powered home that produces as much energy as it consumes. The Technological Residence, Traditional Living, or TRTL, is pronounced 'turtle' and, in fact, resembles a tortoise shell. More important, it offers an alternative to the poorly constructed homes found in the indigenous communities of the North -- housing that not only falls short of modern building standards but also fails to accommodate the traditional lifestyles and values of aboriginal peoples". The Ven. Sid Black, archdeacon for Native ministries in the diocese of Calgary said: "This project offers a durable, fire-resistant and mould-resistant [housing] alternative". "The $300,000, 1,000-square-foot structure was designed in collaboration with the Treaty 7 First Nations of Southern Alberta and had been blessed by Reg Crowshoe, former chief of the Piikani Nation".
