The walkways for pedestrians are important around campus. Have to watch out for rust because it can ruin a pedestrian bridge. At the University of Kentucky they cover the walkways or heat them to not cause any rust to form. Rust means death for the pedestrian bridge. He started by talking about the interaction of environment and buildings. Buildings are important because they contribute to 9.5% to US GDP through construction and renovation projects. Buildings energy use is important because they use 70% of US electricity, and 55% of US natural gas. Buildings are the fastest growing consumer, than transportation and industrial. They use coal, renewable, natural gas, petroleum, and electricity (which is the main one used, and has increased 53% over the years. 2/5 of CO2 in US is related to buildings.
Water is a very important thing all over the world. 45% of water usage if by buildings. Majority of the energy within buildings is used in the HVAC. The electronics are sucking up electricity. 100 watts of electricity in 30 minutes makes 1/2 lb of CO2 from the coal plant where the electricity in Kentucky comes from. Lighting is a very complex analysis process, and is a large component in buildings. Building energy flows can be very complex.

High performance buildings are helping to reduce energy usage. Net-Zero energy buildings produce as much energy as they use. Net-Zero includes: Site Energy, Source Energy, Emissions, and Energy Cost. Each one has a different meaning when people attach it to a building.
LEED is one of the common branding along with energy saving buildings. Putting LEED brand on a building is roughly $40 or $50,000! Energy Star also emerges, and states that they are 30% more energy efficient than regular models.

It's interesting to see how Engineers think about sustainability compared to Architects. It's radically different! Engineers get all technical with various components, while Architects think graphically. We take a more artist approach to our line of thinking. Which I feel makes it more relatable to people outside Architecture.
