I took a first pass at content for the Energy Audit best practice, see the uploaded file. 

In looking for ways to reduce jobsite waste and lower our carbon emissions, I'm working on a business plan for centralized procurement, in lieu of individual project purchasing their own tools, PPE, & consumables.  I'm curious as to how many other GC's on here use (or have used) a central purchasing process and if you have any pros/cons...
