MTG.EEC will coordinate the related activities of TCs and non-TC groups and provide guidance to the ASHRAE membership, manufacturers and end-users on how to classify air filter energy efficiency and the key factors affecting energy usage associated with the proper use of air filtration in new and existing buildings. MTG.EEC is concerned with the nature of particulate and gaseous contaminants, the means of removing unwanted contaminants from the air, the effectiveness, energy efficiency, life cycle cost and sustainable operation of such air cleaning equipment but does not include UVC devices for use in air handling units or air ducts to inactivate airborne microorganisms, which are the province of TC2.9 and SPC 185.
