Discussion Points for Urban Heat Island Effect
Citation:
OConnor, T. Discussion Points for Urban Heat Island Effect. Meeting with Columbia University, New York, NY, December 06, 2018.
Impact/Purpose:
This slide presentation discusses how building orientation may have an effect on green roof soil moisture. It compares moving average temperatures from a green roof and control roof that uses stone as a roofing ballast and shows there are some diffidence in roofing material temperatures but ambient temperatures above the roof are quite similar. The slide presentation then reviews some use of building material including low emissivity windows and alternative building strategies to reduce urban heat island.
Description:
This presentation is a summary of some data from the green roof project performed at the EPA Region 8 Headquarters building as it relates to urban heat island.The volumetric moisture content of a test section of the green roof that gets greater shade from western sun exposure retained more moisture than other test sections exposed to the western sun. Slides show differences and similarities between green roof observed temperatures and temperatures measured on a control roof situated across the street. The second half of the slide presentation is a literature review of some current publications that address sustainable design and urban heat island in other ways.
