Ventilation fans, kitchen range hoods, and laboratory fume hoods can use significant amounts of energy from both the fan motor and from venting heated/cooled air out of the building—air that then has to be replaced and conditioned by energy-intensive HVAC systems.

Has anyone here found an alternative to XPS for the void former?

A structural engineering contact was included in recent conversations about embodied carbon in insulation materials and brought to our attention that this is a common use for XPS that has nothing to do with its insulating properties. It is typically used where concrete is... Read more

It seems like an unnecessary duplication to ask the client to pay for a BECx agent and a Passive House verifier. Or am I missing something? I can't find any LEED... Read more
