Urban residents face higher health risks because urban heat islands exacerbate HW conditions. One strategy to mitigate negative impacts of urban thermal stress is the installation of green roofs (GRs) given their evaporative cooling effect. However, the effectiveness of GRs and the mechanisms by ...
Techniques to Reduce Urban Heat Islands Green roofs, like this one atop Chicago's City Hall, help offset the urban heat island effect. Tim Boyle/Staff/Getty Images Luckily, since we know what causes the urban heat island effect, we can control it to a significant extent. Certain techni...
Heat islands are cities that are often several degrees warmer than the suburbs because the urban areas generate and trap heat. Studies of Atlanta found that temperatures downtown were 5 to 8 degrees hotter than those in the suburbs. This, in turn, increased the number of local storms [source...
The 2021 report "Urban Heat Islands" by Climate Central, which analyzes and reports on climate science, rated Denver a 5.35 on an index assessing the average intensity of heat in a city. The figure shows that based on such conditions as the amount of vegetation, hard surfaces, population den...
Install roof vents (or other vents) and fans to improve airflow. Ideally, they should be adjustable; the fans should also be able to run constantly during the winter months to spread heat out evenly. For temperature control, you should strongly consider a greenhouse heater of some sort. ...
This heat causes water from plants to evaporate. The liquid water turns to gas. This process helps to cool the air. Cities, however, do not have as many plants. Instead, they are full of parking lots, streets and buildings. These are often dark-colored. City roofs are usually dark, ...
Do I need a permit to install a small greenhouse? That depends. Many small home greenhouses won’t require any special building permits, but it’s best to check with your local zoning office to make sure. Should I use glass panels in my greenhouse? Glass is an excellent greenhouse ...
This island was used as a refueling stop for Pan-Am Airways, and the food grown there was used successfully to feed the airline's staff and crew. Similar situations occurred during World War II, as hydroponics was used to grow crops for troops on barren Pacific Islands [source: Time ...

First of all, it is important to recognize that every home is different. Some are on top floors, and therefore, heat rises up to them and it can get very hot inside. Some have glass roofs orconservatories that can act to get very hot. Others have hardwood flooring that can conduct he...
