[Greenbuilding] Growing Media Embodied Energy

Jeff Licht, University of Massachusetts at Boston, has been researching improved media for Green Roofs for the past few years. If I'm remembering the talk that I saw by him lately, a key problem with convetional green roofs is that they use soils optimized for sedums, which don't always grow well in the NE. And I think you're in NY - which isn't too far away. As I recall he uses biochar as part of his soil medium because roofs are high and dry a lot of the time. That allows him to use native mountaintop species as a part of the roof system, and have happier plants. Look him up and take a look at his research. He has a lot of experience coping with the types of problems you're probably facing.
Kind regards,

Ive used Gaia soil a lot with success. But I have have concerns over styrene leaching and its connection to cancer.

Polystyrene chips and beads – they also support microbial life like in a slow sand filter for water or septic – definitely a lot of those in the urban land

Thanks Douglass. Along the same lines, any suggestions on which low embodied agregate would last the longest? Coconut shell? Corn cob? THAT would be a list Id love to see. I know how long it takes for a diaper to break down but not these things.

Hi,
Does anyone know where I could get a list of the different growing media aggregate embodied energy? Perlite, expanded shale, etc? Trying to see what green roof composition is least embodied energy compared to weight.
