1) Rigid insulation with no flame retardants and insignificant global warming potential

Can we replace foam insulation? What does energy modeling really tell us? Find out what you, our readers, have picked as this year’s top 10 stories!

Our resident number-crunchers have spent hours slaving over metrics to bring you … your own most-read BuildingGreen stories of the year. Ta-da!

Are we going to find the same NIMBY opposition to larger solar systems that we’re experiencing today with wind farms?
