Compare sustainable construction techniques in terms of relative cost and performance.

I've not seen your assignment but I'd answer as below but you should alway discuss with your lecturer to ensure your on the right track.
Please do not quote these figures I have made them up.

Example:

Low carbon hempcrete wall £160 per meter square, thermal performance : U value 0.07 W/mK

Brick and block wall £120 per m2, U Value 0.18 W/mK

The lower the U-value of an element of a building's fabric, the more slowly heat is able to transmit through it, there the material is a better insulator.

I'd do a table of various elements, i.e wall, floor, roofs etc... form a comparison. including the pros and cons of each technique.

For extra marks I'd do a cost analysis of capex vs opex say on a mock house.
