The Biomie Construction System - Distributed Manufacturing of Near Zero Energy Home Replacements

This project is relevant to USDA's Strategic Goal to, "Assist rural communities to create prosperity so they are self-sustaining, repopulating, and economically thriving" (USDA, 2014). By creating solutions for rural affordable housing, entrepreneurship, and electric utility financial sustainability, the proposed work simultaneously addresses issues that USDA supports individually through the Rural Housing Service and the Rural Utility Service and aims to do so at greatly reduced overall program costs.Rural Kentucky is facing several urgent issues relevant to communities across the country--an energy-intensive housing stock, a rural electric utility system in transition, and job losses from a rapidly declining coal industry. Three million rural Americans living in pre-HUD code mobile homes spend an estimated $3.8 billion in energy bills every year and contribute to increased peak power demand. As coal-fired power plants are being retired at an unprecedented rate, rural electric co-operatives (REC), which serve 327 out of the 353 persistent poverty counties in the country, are struggling to keep power affordable while undertaking massive infrastructure upgrades. This project aims to develop an ultra-low energy home that is affordable across income brackets and capable of financing the replacement of old, energy-intensive mobile homes using energy savings, while reducing costs for RECs, their customers and industry.Phase I demonstrated the feasibility of: the home cost target, energy and peak power demand reductions of more than 85%, and an enabling rainscreen wall system using rapidly renewable materials. In Phase II, we further develop the BiomieTM construction system. Specifically, we will: develop a vertically-integrated home delivery method with stakeholder input; prototype and test structural panels and their means of connection; design and prototype manufacturing equipment for the system; and project the economics of the construction system and its impact on rural communities. The distributed manufacturing process using farm-sourced materials has the potential to contribute to farm income and create rural entrepreneurship opportunities while cost-effectively improving housing stock and supporting utility viability.
