This document discusses ecological buildings and materials. It poses questions about sustainable building materials, environmentally friendly power sources, and the best and cheapest eco-friendly materials. Some examples of sustainable materials mentioned are double glazing, polystyrene, skylights, earthwalls, concrete and bamboo. Environmentally friendly power sources include wind power, hydropower and solar power. Double glazing, polystyrene and heat pumps are identified as some of the best materials for insulation and heating. The main question is how buildings can be changed to be better for the environment.

17. My big Question

18. My big Question
How Can we Change our Buildings so their
better for the Environment?
Making our buildings more ecological can be really easy, just things like
using environmentally friendly lightbulbs would work. But we need to do
bigger things like using concrete or bamboo, double glazing or skylights.
So if your parents are thinking about renovating your house make sure
they use things like these.
