Show Highlights
Charlie interviews Nick + Asa after their recent LEED Fellow awards.
Understanding how design and buildings can affect a natural environment and affect a natural ecosystem.
Client engagement and the misconceptions that are still out there when it comes to LEED and a sustainable building.
Recognizing your job as sustainability consultants to find the best outcome for clients and projects specific challenges.
Asa shares findings from the LEED Advancement Committee on common misconceptions around LEED.
Emerging technology and trends that everyone should be applying to their businesses.
Current innovations to help you leverage technology to advance the efficiency of how you do things.
The evolution of LEED to grow and create a renewed focus on health, wellness, and buildings being designed, built and operated to be better for the environment.
The crossover and current pathways to combine environmental performance and human performance.
Fundamental values and roles that keep us alive and keep us caring for our families.
“Key misconception I would say is that there's only one path to sustainability. Every building is different and you must understand its history and unique characteristics to really address the potential path toward carbon reduction. Understanding the financial impacts, the lifecycle of equipment and materials…but also just the intangible experience that occupants are having in the building, is equally important.”
-Nick Kassanis
“We really need to kind of go back to our roots. We really need to focus on our local communities. A lot of what we do is try to get buy-in for why it's so important to care for the environment, care about the climate crisis and all these. When you kind of have an introspective and look at the community around everyone, we have to focus on the commonalities. What do we have in common? And I think we all care about our families. We all care about the food that we eat, the air that we breathe, the water that we drink. I think when you look at those fundamental values you can then start caring about why the environment plays a big role in those key things that keep us alive and keep us caring for our families. So then we can focus on helping our local communities and get that buy-in from people that may have different opinions from ourselves.”
