Welcome back for part 2 of Jacob's lecture from the PassivhausMAINE lecture series on addressing embodied carbon in our built environment.  We close the episode with a song from one of the bands Jacob records with; Fantasma by Mal Maiz! Enjoy!   Cheers!

Chris and Phil were not only lucky enough to attend a lecture by Jacob Racusin, but they were also able to record it! Our friends at PassivhausMAINE invited Jacob to share his insights on low-impact, high-performance building technologies and discuss some of the ground-breaking work he has been involved in lately regarding plant-based construction and carbon sequestration in our built environment. He's a wonderful speaker with contagious passion for combating climate change through better building.  This is part one of his lecture, be sure to check out part two which will be released in about a week. Also be sure to visit our lame facebook page for cocktail recipes and links to Jacob's slide deck. Visuals help, but the the audio holds up on its own as well.  Also, new theme song. Cheers!
