Is there any special considerations for a project registered (v2.2) and designed 10 years ago is now being constructed. V2.2 and v2009 have expired so we need to register it for v4.

Does anyone know if either prereq EA - Minimum Energy Performance, or the Optimize Energy Performance credit need a third party review as it did under the CaGBC's LEED 2009?

Hi, I am QA'ing a model for a building that will be fed via a cogeneration plant (with absorption chillers) and therefore is a little complicated.

Dear All, Our project building is located in Istanbul/Turkey. Cooling will be provided by centralised two chillers. There is not a cooling tower.

Hello everyone, We are working with a building that has a complicated geometry, and the selection of the baseline system is not that evident.

Minimum Energy Performance Calculator on process loads tab under receptacle equipment modeling methods paragraph indicates there are three options to model receptacle equipment: average equipment p

Dear All, I want to know that is it mandatory in LEED that we must have a fresh air in each occupied spaces of a project OR we can comply just by providing overall fresh air of the project accordi

In a Jurisdiction where code is surpassing ASHRAE 90.1-2010 LEED buildings are required (by code) to meet the more stringent requirements but measure their energy score based improvement from ASHRA

Hi, Is there any limitations in LEED V4 regarding process energy that it should be minimum 25% (In proposed case) of the baseline energy cost for the building.

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.
