We are in the design and planning stage of a 7000 sq ft tirebale demonstration building under a non-profit project called PEARL, Permaculture Education And Research Lab. The site consists of 63 acres in Northcentral WV.
We are partnering with a local baling company, Tyrex, 1 hour away, to source, deliver and set the bales.
We recently obtained approval through West Virginia DEP for the structure and because it is not currently defined as a residence, the building permitting process and costs are negligible.
Our design is still a work in progress. We plan to run all the specs/design by a structural engineer.
The basics include a 9' deep excavation into a southwest facing slope for three 36" courses in running bond pattern, a clerestory roof design with south side glazing/operable doors and 4' wide planters the length of the building, operable clerestory awning windows, second story loft with walkouts to North side grade level which slopes downhill North to diversion ditch. All North walls will have a French drain to daylight. Multiple Earth tubes for cooling via floor vents. Solar panels and passive solar hot water heaters mounted to south sloping roof. Two 2000 gallon cisterns on east and west ends. Insulated concrete floor (still deciding for or against hydronic heating?).
We have lots of ideas for other systems but that's the basics for the shell.
