Proponents of extremely tall buildings have told City Council that their buildings will be “green” and incorporate Leadership in Energy & Environmental Design (LEED) standards. CityHallWatch takes no position for or against any height of building, but calls for a fair and open public discussion on the topic, and encourages public awareness of the issues and complexities involved.
Wikipedia provides a useful background on LEED.
Leadership in Energy & Environmental Design (LEED) is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies intended to improve performance in metrics such as energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.
Now, below is an interesting link from no lesser authority than the National Research Council of Canada, which investigated energy performance of LEED buildings. What they found is that while LEED buildings overall appeared to perform better, energy performance of LEED buildings had little correlation with certification level of the building, or the number of energy credits achieved by the building at design time. Some LEED buildings actually performed 28%-35% worse than average.
Here are some other articles which provide some scepticism to LEED claims. There is a new a term called “LEEDwashing,” which refers to architects manipulating LEED to present non-energy-efficient buildings as green.
