This weeks segment looks at how glass skyscrapers are negatively impacting the environment. 

Transcript:

Glass skyscrapers are having negative impacts on our environment.

This is the Iowa Environmental Focus.

Architects have known for a long time about the difficulties of keeping glass buildings from overheating. When glass office structures became popular choices for new developments in Chicago during the 1880s, practical ventilation methods were used to reduce the heat inside of these structures, but this was only somewhat effective. Modern conveniences, like central air conditioning and central heating, make temperature regulation much easier.

High-rise, glass-paneled buildings are visually striking, but the designs and materials of these buildings make them inefficient energy users. Temperatures are hard to regulate in glass structures, and taller buildings use significantly more energy than shorter ones. Buildings that reach over 20 stories use about twice as much electricity per square meter than buildings under 6 stories.

Environmentalist have been working to restrict the number of glass high-rise developments in the cities across the country. While there are some benefits to glass—like natural lighting—architects are still working on ways to make high-rises more environmentally friendly.
