Each one gets its own sheet: what the problem was, what I tried, the numbers, and what I'd do differently. Work for clients comes first, then the projects from school.

Sizing a septic tank and leaching bed for a two-bedroom dwelling from Ontario Building Code Part 8, from the daily design flow through tank compartments, chamber length, trench layout and a sensitivity check on soil percolation time.
T = 20 is right on the edgefiled underBuilding code designSustainability
An energy and operating-cost comparison for replacing two 15 kW electric furnaces with three hydronic unit heaters on a gas boiler. It covers capacity from the manufacturer schedules, seasonal energy, demand charges, alternatives and a break-even gas price.
