We believe once you have used our tools, you will want to use them on every project. But we recognize yet ANOTHER tool to learn is probably not high on your list of things to do. We therfore offer challenge ConstructIQ. You will be given a series of questions you might find in an architectural spec. From there you have to find materials, extract the VoC, EPD and HPD information and create USGBC calculators. The higher the LEED score from materials the better. The account will be free and you have 7 days to complete the challenge.
