A life cycle assessment is an evaluation of the environmental impact of the materials used in a building “from cradle to grave”.
One of the code officials at the IgCC hearings summarized it this way:
The calf is born
You raise the calf, feed it and shelter it.
After about 3 years you kill it, butcher it and eat it.
As you are sitting around the BBQ grill with your friends, enjoying your steak, you say ”This is tasty.”
Alright alrghit alright that’s exactly what I needed!
