Twelve weeks, each with one engineering question, one named method, and one worked example at the site where that week's climate bites hardest.

Lectures

Each lecture poses a concrete question, names the method that answers it, and works one example through with real numbers. Every week from 2 to 11 carries a Five sites section, because the answer is different in five places and the difference is the point.

Weeks 1 and 12 integrate all five sites. In between, each site leads two weeks — one where its climate helps, one where it hurts — so no student’s preset is quietly the easy one.

Weeks 1 and 9 carry slide decks. They are the two weeks where the argument is mostly one number changing shape.

Each lecture opens with a week overview that says where the week sits in the commission and what the matching tutorial produces.

What crosses the fence line

Week 1 — the household's annual demand, the definition of closure the course scores, and the site sheet every later week writes into

Week 1 · 22 February 2027

Water is the yield limit, not sunlight

Week 2 — evapotranspiration, effective rain and the monthly deficit that decides how much of your growing area is actually productive

Week 2 · 1 March 2027

Mushrooms are a converter, not a crop

Week 3 — biological efficiency, species temperature bands, and what happens to five kilograms of spent substrate for every kilogram you pick

Week 3 · 8 March 2027

The scraps-to-larvae-to-fish loop does not close

Week 4 — threshold temperatures, bioconversion on a dry-matter basis, and the arithmetic that shows the most-drawn diagram in permaculture is mostly imports

Week 4 · 15 March 2027

Which fish you may keep, and for how many months

Week 5 — feed-rate ratios, stocking limits and seasonal species rotation, plus the jurisdiction question the thermal model cannot see

Week 5 · 22 March 2027

Getting March's surplus to August

Week 6 — the storage balance between a harvest curve and a consumption curve, and why one tested recipe is the only safety guidance this course will give

Week 6 · 12 April 2027

What a roof can actually deliver

Week 7 — the enHealth runoff formula, a capped bore, and the month-by-month supply curve that every later water decision is built on

Week 7 · 19 April 2027

Log reductions, not reassurance

Week 8 — the multi-barrier train, what each barrier is measured to achieve, and the difference between a filter's laboratory figure and its field figure

Week 8 · 26 April 2027

The month the tank runs dry

Week 9 — the monthly storage balance, why annual averages hide drought, and a synthetic dry-year dataset to test your design against

Week 9 · 3 May 2027

Every stream goes somewhere

Week 10 — routing food waste, spent substrate, meat and dairy and fish sludge through compost and digestion, and closing the mass balance that is not banded

Week 10 · 10 May 2027

The nitrogen has nowhere to go

Week 11 — sizing excreta and greywater systems, the uptake limit that caps every site, and the greywater rule that is the law in a state none of you is in

Week 11 · 17 May 2027

What fails first

Week 12 — assembling the whole household model, testing it against the two hard constraints and a dry year, and naming the failure you cannot design away

Week 12 · 24 May 2027
