General guidelines for writing projects:

It is suggested, but not mandatory, that you please write the projects in three
parts:

1. An "executive summary", which says very briefly what the project is about
   and what your main conclusions are.

2. A main part, which provides details.

3. Separate appendixes, if wanted, for supporting graphs and maple printouts.

Typos and comments re Project on "heating building":

- in 2d, h is to switch between 5 and 0  (change '1' to '5' & fix typo "AT")

- "is assume" should be "us assume"

- To emphasize: explicit solution not requested in 2c.

- Add to statement of 2d, in future versions:
  Hint: you might want to design a furnace switching schedule which keeps the
  temperature, as much as possible, between two values like 2.5 and 3.5
  (or a narrower range).
