LEED is primarily concerned with the building construction. The Green Clean Institute is more concerned with the cleaning program. The construction is a huge one-time commitment that addresses energy use, building materials, ventilation, carpet, and furniture. Once done, a Green building can degrade from this pristine status to a not-so-green eco-system.
Not all buildings are built as Green or efficient. New buildings can include the latest designs and energy-saving features. The cost to renovate older buildings can be prohibitive and interrupt business for months and years. So, we asked the question, "What can any building do to improve the Green and Healthy aspect of new or older buildings by simply transitioning existing factors within the building?"
