Demolished and rebuilt envelope
NC-v4 EAp2:Minimum energy performanceposted by Francesco Passerini on
If the envelope is demolished and then rebuilt with the same shape does Table G3.1 part 5., baseline, point f apply?
Baseline HVAC System Type - for laboratories
NC-v4 EAp2:Minimum energy performanceposted by Carol SR on
Hello! I am constructing a building model which spaces are half offices, half laboratories. The HVAC system chosen is system 5 (packaged VAV with reheat) for all building, since it is considered a

Hello, I have a question regarding equivalent standards : Is there an USGBC approved equivalent standard for projects located in France ? Many thanks in advance for your assistance.
DES Engineering Analyis to Determine Losses Path 2
NC-v4 EAp2:Minimum energy performanceposted by Ryan Hoffman on
The LEED v4 Reference Guide offers three was of determining equipment efficiencies, distribution losses, and distribution pumping energy: Monitored data, engineering analysis, and default values.
Process energy cost
NC-v4 EAp2:Minimum energy performanceposted by Charline SEYTIER on
Hi everyone, Reading the v4 reference guide, it seems that the default process energy being 25% of total energy cost for the baseline disappeared from the requirements. Have you also noticed it?
electric transformer
NC-v4 EAp2:Minimum energy performanceposted by Francesco Passerini on
In the building there is an electric transformer that transforms the electricity coming from the grid into low voltage energy. The transformer is particularly efficient.
Using different energy rates between CHP Proposed and Baseline
NC-v4 EAp2:Minimum energy performanceposted by Mark Benson on
I know that the 90.1 and the LEED Reference Guide generally tell you to use the same utility rate structures for both the Proposed and Baseline models.
Is this plant qualified as a DES?
NC-v4 EAp2:Minimum energy performanceposted by Aru Sau on
1. We registered the project as Campus consisting 3 Buildings. Central Plant Building and the future building is not included in the LEED boundary. 2.
District Energy Systems
NC-v4 EAp2:Minimum energy performanceposted by Bob Crowell on
Marcus or anyone who knows the answer, I have a squash facility that is being added on to an existing building. The LEED Boundary does not include the plant. 1) The existing plant serves only one
Energy modeling for LEED BD+C: Core & Shell
NC-v4 EAp2:Minimum energy performanceposted by Hanh Truong on
Dear all, We have a project targeting LEED BD+C: Core & Shell. My question is how to model whole-building energy simulation?
