When designing a single family home in Canada, what is the best type of framing to use in order to reduce carbon emissions/ embodied energy/ wasted material? Is traditional stick frame with dimensional lumber better than using engineered studs/joists (LVL or LSL)? Assuming the engineered lumber has greater strength and depth spans, does this offset the higher embodied energy to produce the engineering vs traditional lumber?
