If you can't use a natural renewable resource for something then you should at least be as efficient as possible with current methods.
We at Fine Earth have taken the necessary steps and continue to operate as efficiently as possible. Our home office was tested and rated by KCPL (Kansas City Power & Light) as being 130% inefficient in 2008 - OUCH!!! By the end of 2009 we were operating at a 40% efficiency rating. The designated target rating is 30%. Any facility must have outside fresh air of at least 30% turnover to maintain good air quality.
Our persuit of efficiently operating will continue, join us in making our world a better place.
