Pennsylvania urged to adopt regulations for data centers to combat heat island effect
The article discusses the urban heat island effect, exacerbated by data centers, in light of a recent heat wave in Pennsylvania. It advocates for stronger building codes, zoning laws, and a proposed three-year moratorium (Senate Bill 1359) on hyperscale data center development to mitigate warming and protect communities. The piece also suggests prioritizing green infrastructure, native plants, and lighter-colored building materials for cooling.
A recent severe heat wave in Pennsylvania, with heat indexes reaching 112 degrees Fahrenheit, has brought renewed attention to the urban heat island effect. This phenomenon, which significantly raises temperatures in developed areas, is exacerbated by the proliferation of data centers and warehouses that replace natural, permeable surfaces with heat-absorbing materials like metal, concrete, and asphalt. The 2024 Pennsylvania Climate Change Impacts Assessment projects a 7-degree increase in the state's annual temperature by 2050, leading to increased heat-related illnesses, longer allergy seasons, and other public health and social issues.
The article highlights that AI data centers consume vast amounts of energy and generate substantial heat, in addition to using millions of gallons of water daily, with emerging research suggesting they can increase local temperatures by up to 16 degrees for miles. It notes that tech corporations are accelerating data center construction in Pennsylvania despite significant resident disapproval. In response, the article urges state lawmakers to support Senate Bill 1359, which proposes a three-year mandatory stoppage on hyperscale data center development, labeling it the most aggressive current legislation to pause such projects.
Beyond legislative action, the piece calls for smarter planning and retrofitting strategies. It emphasizes the cost-effective role of hardy, properly placed native plants in cooling communities, citing EPA data that shows shaded areas can be 20 to 45 degrees cooler. The article suggests that local planners, including Schuylkill County, should factor in the economic benefits of green infrastructure, similar to New York City's initiative to expand tree cover. Additionally, it recommends mandating lighter-colored, reflective roofs and permeable pavements, which can significantly reduce surface and indoor temperatures, thereby lowering cooling costs and mitigating runoff.
