The core team additionally continued double checking the Earthbag Village energy specifics for the solar microgrid design, sizing, and cost analysis. We interviewed 2 volunteers to assist with this task and the same process that will be applied to the City Center, Straw Bale Village, Ultimate Classroom, and Aquapini and Walipini Structures next.

We’d say we’re now 90% of the way done with the energy consuming components within the Earthbag Village. We added additional details for how we arrived at different numbers of units, added percent use, and worked with Frank to estimate energy use by potential HVAC system for the Tropical Atrium, water heater for eco-showers, and some greywater pumps.

We also added the time of day the power draw occurs from the different power demands. See below for related pictures.

Jose Luis Flores (Mechanical Engineer) completed his 45th week helping finish the Net-zero Bathroom component of the Earthbag Village. This week Jose Luis completed the calculations for the maximum scaling factor of the Net-Zero Bathroom roof with the addition of an exterior support column.

He completed the calculations by assuming the distributed load was uniform on the wall and made the max distance from the reaction force on the wall to the center of gravity to be 60% of the distance from the edge of the wall to the column. The weight of the roof was related to the radial beam length and the radial beam was related to the length of the external column.

By substituting these relationships, the length of the exterior support column was calculated. The weight equation was then used to solve for the reaction force on the external column and set it equal to the equation of the critical load before buckling. This was used to solve for the maximum length of the external column and then used to solve for the length of the radial beam.

With the equation used to calculate the area of a trapezoid, the surface area of the roof was calculated. The next step will be to review the calculations to look for any discrepancies and then add it to the Net-Zero Bathroom Tutorial/Instructions and add the spreadsheets. The pictures below show some of this work.
