Hi, We received the design and construction review, and the reviewer indicate us that two units that's appear on the prerrequisite EAp3 documentation are not included.

Hello, We were previously unable to achieve this credit for a project receiving chilled water from a campus central plant employing 4 electric centrifugal chillers and 3 heat recovery chillers.

I have a project with a commercial kitchen, so we're gathering info on all of the walk-in coolers, freezers, etc.

Hello, Was just wondering if someone could shed some light on the Refrigerant Charge and how I go about finding it? I am using R-410A as the refrigerant. Thanks.

Hi , There is no mention of screw chillers either under the credit EA 4 or ASHRAE application. I can only see absorption, scroll and reciprocating. Can someone please help me with the life span to

For refrigeration equipment(Freezers/coolers etc etc) what is the life expectancy that should be put into the EAC4 template?

we use VRF system for A/c we use value given in LEED guide Rc 2.2 lb/ton As per the the default calculation we get points but the reviewer tells Rc for VRF is very low it may be "3 - 6" lb/ton

Has anyone had any experience combining the approaches in Option 1 and Option 2 to achieve this credit? We plan to use economizer cooling for most of our cooling needs.

Hi, I'm hoping to get some feedback on what is actually required to be uploaded in support of table 4-1.

Hi all, Is it possible to use the refrigerant R-1234 (HFO) to replace the R-134 in a centrifugal chiller? It has low GWP (around 4 or 5) and zero ODP, but it is not in the LEED online form nor in
