Hey, did you know empty buildings can make our block up to 20 degrees hotter? There are cool ways to fix this — check out what Texas A&M found about turning them into gardens and community spaces!

Abandoned buildings and paved-over vacant lots are making Houston neighborhoods significantly hotter — in some spots by up to 20 degrees. New research from Texas A&M University suggests cities don't have to default to demolition. Repurposing empty spaces as urban greenhouses, vertical gardens, and community hubs could cool things down while saving money and cutting carbon emissions.
Texas A&M researcher Dingding Ren led a study showing that vacant buildings and lots drive up local temperatures by as much as 20°F. Ren argues that adaptive reuse — converting existing structures into productive spaces — is cheaper and greener than tearing them down. Demolition releases large amounts of carbon dioxide and creates construction waste. Reuse preserves the energy already embedded in a building while helping cool the surrounding area. Local officials are already acting on smaller scales: Houston City Councilmember Mario Castillo launched the Resilient H initiative, which will create a 'cool corridor' on Cavalcade Street in Near Northside with new plants and bus stop shelters. Harris County Precinct 4 is planting 2,000 trees in Alief and partnering with the city on a $4 million shade and tree project in Gulfton and Sharpstown.
You can use this research to understand why some Houston blocks feel unbearably hot and what kinds of changes can help. If you live near vacant lots or empty buildings, this gives you language and evidence to bring to a neighborhood meeting or a city council member's office. The research also points toward policy tools — tax incentives, grants, zoning flexibility, and public-private partnerships — that local governments could use. Knowing what's possible helps you ask for it.

This research connects to broader conversations about Houston's urban heat island effect, flooding resilience, and equitable investment in neighborhoods like Alief, the East End, and Near Northside. It also ties into ongoing work at the Kinder Institute for Urban Research at Rice University, which has tracked heat disparities across Harris County. The Greener Gulfton community action plan and the Uplift Gulfton and Sharpstown project are real local examples of what this kind of investment looks like on the ground.
Houston summers are already brutal. Research using drone images and NASA satellite data shows that vacant and impervious land — surfaces that can't absorb water — traps heat and pushes land surface temperatures even higher. More than half the land in some Houston neighborhoods is impervious. Tackling abandoned properties isn't just about blight — it's a concrete way to protect neighbors from dangerous heat.
