Innovations in building materials and new construction technologies must be utilized in order to control the GHG emissions released in the construction of our city's ever growing housing supply. Green Violin’s innovation is to replace high carbon footprint cement in their concrete mixes with low carbon alternatives and then to utilize rapid construction through 3D Concrete Printed House technology. They will build and demonstrate Edmonton's first 3D Printed Concrete House. This demonstration unit will pave the way (no pun intended) to a brighter, greener future for cities to have cleaner, more energy efficient housing options for everyone to call home.
