Medgar Marceau joined Morrison Hershfield in 2008 with a unique mix of building envelope, energy modeling and life cycle assessment experience. In addition to Medgar’s building science expertise, he has extensive experience in whole building energy simulation, building envelope systems, life-cycle assessment (LCA) and material science including infrared thermographic analysis, modeling of air and moisture transfer through envelope systems, air leakage, and mass transfer. He is an expert on concrete structures and material properties of concrete and has conducted numerous investigations on concrete failure. Medgar has authored and co-authored dozens of publications on the subjects of life-cycle assessment, commercial and residential energy use, and sustainability. Medgar’s sustainability goal is to help designers increase building durability and reduce building energy consumption.
