Good evening,

I am looking for suggestions to replace"wood" siding at the 25-year-old Lyle Center for Regenerative Studies and as always there is no solution that does it all.

Hello SCL, 

If you didn't attend last week's SCL Summit, then I'll sum up one of the major takeaways: SCL members NEED TO COMMENT ON LEEDV5. The stakes are high, particularly around waste. 

Luckily, Amanda Kaminsky is making it easy for us. She has drafted a sample comment based on our discussion at the Summit. 

If you have... Read more
