Jim is an interesting speaker, funny and informative, peppering his data-rich talk with informative graphics and real-life examples. The takeaway from that : paraphrasing, The choices you make can make a difference.
Looking at green building with a different lens, Jim talked about the energy that is used in making a green building, and the major energy hogs in making a building. It was interesting to note the Global Warming Potential of foam, and the importance of going local. Transportation Energy : the energy used in transporting people to the site is a major hog. He also talked about materials, their Global Warming Potential and how choices of materials can make a difference in the overall sustainability of the building. It was great to hear about how to make construction more sustainable, while keeping the same performance of the buildings.
