Hello, 

I am struggling with understanding if I should be using Annual Marginal Emission Factors (MEF) or Annual Average Emission Factors (AEF) for evaluating different building design decisions.

Anyone else having this experience? We've got a LEED 2009 Core/Shell project that we've now been contracted to do a fitout within for one of the first tenants.

Hi all,

We're seeing more interest and desire for outdoor work spaces, and as we consider the design implications around working outdoors, teams have been asking about wind comfort.
