Free Training for High Performance Residential Design and Construction

MI-BEST® (Mobile Integrated Building Energy Science Training) Series - July 16 through July 20

Published:  June 13, 2018

MI-BEST is a series of five consecutive days of training designed to be taken in sequence. MI-BES joins the art of construction to the science of energy and moisture management. It provides building professionals an opportunity to learn and practice techniques that might otherwise take many residential projects to experience and troubleshoot. Students are encouraged to stay for the entire series but may alternately sign up for individual days to learn specific skills.

These trainings are organized by PG&E and offered in collaboration with the County's General Services Energy and Sustainability Division, County of Marin Community Development Agency, and Sonoma Clean Power. Lunch will be provided for class participants.
