[Bldg-sim] EUI calculation using ECB Method and PRM Method

For our projects, we model a "typical construction baseline". This
model represents the Owner's concept constructed to the average new
construction characteristics based on our experience, input from the
design team and input from the cost consultants/contractors. The
Proposed design model is constructed to match the teams "concept
vision". Schedules are set based on the intended programming and
adjusted for typical diversity for such a facility.
We compare these two models as well as give an indication as how the
Proposed design might compare to the "standard" the project might be
trying to achieve - not necessarily LEED. Costs and energy use
intensity is compared.
The issue with absolute EIUs is an accurate base to compare to. As
Luka mentioned, it would be helpful to normalize the Proposed design
EIUs to Portfolio Manager or another source baseline EIUs.
