Critical Review and Gap Analysis of Impacts from Pavements on Urban Heat Island

The objective of this study is to identify knowledge gaps regarding the scientific understanding of UHI and effective mitigation measures, with a focus on the use of cool pavements. We first reviewed scientific papers, reports, and online articles published in the past decade to summarize recent scientific advances in cool pavements. We reviewed existing efforts […]

What’s Cooler than Cool? Cooler Pavements for Urban Heat Island Mitigation

TRB is hosting a series of Urban Heat Island recordings in July and August 2020. Part 1 provided an overview of the UHI phenomenon. Presenters explored why cities and agencies are looking to reduce the UHI effect and what the current understanding of UHI is. They also quantified the impact of pavements on UHI. The videos are available. Presenters: Kamil Kaloush, Arizona State University […]

Nanoparticle-Filled Liquid Fuels for Efficient Energy Conversion

Nanofuels exhibit great potential for increasing the combustion efficiency of liquid-fueled engines, because of their enhanced thermal and mass transport properties, their higher volumetric heating value relative to pure liquid fuels, and the extremely high surface-area-to-volume ratio of the energetic nanoparticles. Nanofuels, or nanoparticle-filled liquid fuels, are one type of nanofluid, i.e., a nanoscale colloidal […]

Solar-Powered Adsorption Cooling

Solar-powered cooling is an attractive concept in that one utilizes solar energy, which is the largest component of a building’s cooling load, to drive a heat-activated air-conditioning system, thus reducing or eliminating the need for conventional, electric-powered air conditioning. Most solar-powered air-conditioning systems to date have been based on well-known absorption refrigeration, which requires difficult-to-handle […]
