Energy savings are a way of life at Twenhofel Middle School.

Twenhofel Middle School was one of CMTA’s first schools to introduce a curriculum integrated energy dashboard. This Fall 2012 High Performing Buildings article details the school’s sustainable features.


Baby Steps to Zero Energy

When Plano Elementary School opened in 2007 it was one of the most energy efficient schools in the country. The school’s energy use was so low that the local utility changed the meters out twice believing they were malfunctioning. This Fall 2009 High Performing Buildings article shows how Plano achieved this low energy use.


CMTA "Walks the Walk"

CMTA's headquarters was built with two goals in mind: significantly reduce energy use and create a learning lab environment to test new technologies for high performance buildings. The building was the first LEED Gold office building in Louisville and received a perfect ENERGY STAR rating of 100.
