� Graph from the dynamic energy simulation illustrating the annual electrical load
profile of the proposed building, highlighting the peak and annual average
electrical loads;
� Calculations confirming the percentage increase in peak electrical load compared
to the annual average electrical load; and
� Narrative describing each of the major peak load reduction strategies, along with
drawings, equipment data sheets/specifications as necessary to illustrate how and
where the chosen measures are incorporated into the proposed building design.
� Graph from the dynamic energy simulation illustrating the annual electrical load
profile of the as-built building, highlighting the peak and annual average electrical
loads;
� Calculations confirming the percentage increase in peak electrical load compared
to the annual average electrical load; and
� Updated narrative describing each of the major peak load reduction strategies,
along with as-built drawings, equipment data sheets/specifications as necessary to
illustrate how and where the chosen measures are incorporated into the as-built
building design.
� The peak and annual average electrical load (MW) must be determined from the
modeling results of the dynamic simulation undertaken as part of RE-R1 Minimum
