Materials and building envelope systems
6044328402

Dr. Fitsum Tariku’s experimental and computer modeling research program spans from materials and building envelope systems right through to whole-building performance analysis. Currently, he is working on material property measurements and characterizations; hygrothermal modeling and measurements of building envelope systems; and integrated analysis of whole-building performances. He aims to develop a comprehensive building optimization and decision-making tool that integrates whole-building simulation, risk assessment and cost-benefit analysis, with the objective of designing a building that is energy efficient, durable, economical, environmentally friendly, and provides comfortable and healthy indoor air quality to occupants.
