Jose Luis Flores (Mechanical Engineer) completed his 37th week helping finish the Net-zero Bathroom component of the Earthbag Village. This week Jose Luis completed the heating elements effectiveness calculations. The calculations were done in order to quantitatively determine how many heating elements should be used depending on the climate.

The calculations determined how long the water or rain water storage room would take to reach freezing temperatures. Knowing the time was crucial to maximize the efficiency and cost effectiveness of the type and quantity of heating elements necessary to keep the room and rainwater at above freezing temperatures.

The section added covered the heat loss associated with the structure such as the walls and the roof and the heat loss of the water stored in the top center barrel. The findings help determine where to install the heating elements to further maximize their effectiveness. Illustrations were added to the section to help visualize the placement of the heating elements.

Jose Luis then began updating the roof plan to coincide with the latest additions to the SolidWorks rendering such as drip edge flash on the edge of the exterior roof panels. He also began rearranging the AutoCAD models to follow the order of the Net-Zero Bathroom tutorial/instructions. The pictures below show some of this work.

Vicente J Subiela (Project Management Adviser) completed his 12th week working on the solar microgrid design, sizing, and cost analysis specifics. This week Vicente added new tabs to the sizing tool: a specific one for the Earthbag Village energy demand and another for the feasibility analysis and economic balance vision on the long term.

This tool allows having a vision of the evolution of the annual energy & economic balances, and how the economic rates affect the net balance. Vicente also continued the follow-up of the collaboration team. He has repeated the simulations with SAM to find the best match with the outcome from a potential PV supplier. Pictures below are related to this work.

Aidan Geissler (Sustainability Researcher) completed his 9th week helping with 2nd-to-final review, feedback, and content editing. This week, Aidan’s work for the week was devoted to compiling information for the Insulation Comparison Spreadsheet.

He researched and assigned point values to features pertaining to sustainability, safety, and effectiveness for various insulation products made with wool, straw, hemp, keraf, and magnesium oxide from seawater.

In order to compare the costs of these products while taking into consideration differences in R-values, Aidan calculated the average price per square foot per R-rating for each product. The pictures below relate to this work.

Jeson Hu (Mechanical Engineer Assistant) completed his 6th week helping with research related to the solar microgrid design, sizing, and cost analysis specifics. This week, Jeson researched the best solar inverters and studied the related specs. He also finalized the best solar harvesting technology research.

The answer to the best technology or company or product is not clear without the cost input, which he is struggling to find. Almost all the companies contacted did not have much interest in this 2MW project. However, Jeson provided their product specs and contact info for future reference.

He also determined that, if One Community wants to have a battery bank, a battery based inverter would probably be the choice. The pictures below share some of this developing work.
