The Manufactured Housing Laboratory (MHLab) is a 1600 ft2 ENERGY STARŪ manufactured home that serves as a training center and building science laboratory. The MHLab features two complete separate heating and cooling systems: an overhead duct system connected to a package unit air conditioner with electric resistance heating and a floor-mounted duct system connected to a split system air conditioner also with electric resistance heating.

MH Lab Details & Contact Info
