- 5. What is Cool Pavement? ■ The term traditionally refers to paving materials that reflect more solar energy (higher albedo) to remain cooler than conventional pavements – enhance water evaporation (evaporative cooling) –or have been otherwise modified (lower emissivity)

Notas del editor
- Hi Everyone, thank you all for being here this evening. I am Neil Debbage and I am an associate professor at UTSA who's work focuses on urban climate. Tonight we are here to think about how we can leverage data to observe and ultimately improve our city, and I will be sharing one example of how we can do this specifically related to the City of San Antonio’s cool pavement pilot. We can see one of the cool pavement installations below on Grant Ave.
- Simple answer is it has been hot Shattered number of 100 degree days Also set the record for consecutive days over 100 Due to high pressure sitting over our region, preventing rain; but we also no that in some places in the city it is much hotter
- July 12, 2018 surface temperature Talk about clear urban signature; disparities Surface properties have a big influence so can we alter them to cool things off as well
- Part of our broader CAAP efforts Mitigation strategy number 20
- City installed two additional ones after the field work was started so we did not get to those
- Durashield is an acrylic coating with silica Solar Pave is an acrylic polymer Plus TI is an oil based tiatianum dioxide spray; doesn’t change appearance or albedo but does alter emissivity (amount of heat radiated)
- School of Architecture + Planning and Geography Design of site and control Times 6 -7 12 - 1 4 – 5 and 9 – 10 Spent half a month (15 days) this summer collecting data and just finished up a week and a half ago Mention infrared gun here
- Walk through net radiometer Discuss the importance of difference temperatures

- Think about longer term more permanent data collection like a mesonet Acknowledge COSA, UTSA, cool pavement team
