The Discover phase of engagement with our Equilibrium team combines energy modeling, engineering design, decarbonization strategy and whole-building facility condition assessments to deliver a practical, actionable plan for the facility being addressed. This data is used to develop a formal return on investment model, project scope and budget via our experienced team and vetted LMMW Partner Program contractors.



LMMW Group Ltd. offers energy and facility services, operating under the L360 and Equilibrium Engineering brands.

LMMW Group Ltd. (”LMMW”) was launched in 2022 by Marc MacDougall, William Marshall, and Chad Wiesner, in partnership with Lindsay Construction Limited – the largest construction firm in Atlantic Canada.

By leveraging our ownership group’s combined experience and extensive network of vetted trades contractors and suppliers (LMMW Partner Program members), LMMW is structured around an “integrated delivery process”, rather than around the individual energy and facility services we provide. This enables us to help our clients efficiently move projects through all the phases of a deep energy retrofit or facility optimization project (from initial studies to project implementation to ongoing maintenance), while maintaining flexibility to shop multiple product and service options.
