    • One of the world's earliest geological maps was recently pulled from the Academy Archives and put on display for visitors, but only for a few days as it is quite delicate and rare.

      The World Underfoot

      November 16, 2015

      Eighteenth-century land surveyor William Smith was a rock star. And we mean that quite literally — Smith’s 1815 map of England, Wales and part of Scotland was the world’s first look at the organization of the earth beneath our feet. Less than 200 copies of this seminal work exist today and the Academy of Natural Sciences of Drexel University owns one of them.

      A.J. Drexel Institute for Energy and the Environment Plots a Course for Philadelphia to Reduce Greenhouse Gas Emissions

      November 04, 2015

      Researchers from the A.J. Drexel Institute for Energy and the Environment issued a 97-page report to the City of Philadelphia that plots a detailed course for how the city can reduce its emission of greenhouse gasses—with the goal of an 80 percent reduction by the year 2050. Among its suggestions are retrofitting hospitals, grocery stores, schools and retail stores with better windows and insulation; drawing electricity from low-carbon sources like nuclear, wind and solar power; and encouraging the use of electric vehicles, public transportation, walking and cycling.

      Diagnosing 'Sick' Buildings to Save Energy

      September 09, 2015

      Are you feeling too cold right now? Too warm? Is your office's air a little stale today? On average, Americans spend 90 percent of the day indoors, in a controlled environment. Controlling that environment, at least in the workplace, is the Sisyphean labor of building operators. “Operating” a building requires not only striking the perfect balance between heating, cooling and ventilation, but also repairing and maintaining all of the equipment and systems that allow this magical equilibrium to exist. Endlessly pushing a boulder up a hill might actually be less work. As part of a grant from the U.S. Department of Energy, researchers from Drexel University are working on a cloud-based data analysis tool that could help consolidate these labors while also spotting undetected problems that lead to wasted energy and poor indoor environmental quality.
