Abstract
This study evaluates the potential of concrete 3D printing for the construction of net zero energy affordable homes in the Midwest region of the United States. The study examines the need for thermal insulation in this construction type and compares the predicted energy savings to the cost of the investment in 3D printed construction. The case-study consists of three steps: 1) an analysis of the 3D printed envelope to understand its thermal properties and consider two options for locating insulation in the wall; 2) an energy simulation of the home to understand the predicted energy consumption and potential savings in monthly utility bills; and 3) the calculation of the simple payback for the initial investment in 3D printed technology. The financial analysis of the payback period is used to verify the affordability of the 3D printed home. It is expected that the results of this case study help inform the design of 3D printed envelopes towards energy efficient and affordable residential construction.
