The refrigerant used on my project is not listed in the LEEDv4 form and as recommended on the FAQ section for this credit I am using the LEEDv2009 form to document compliance.

I am working on a large project for which the cooling is predominantly from central chillers providing chilled water. This complies easily with the requirements of EAc4.

Hi all, For a new construction project, the fan coil unit schedule shows that the fluid for the cooling coil is 30% PG (Propylene Glycol) and that of the heating coil as 40% PG.

Which part of a Split System should be considered for the refrigerant charge calculation?

Hi!

I can see that similar questions have been asked before, but I can’t find any answers:

i was looking at the uploaded cutsheet under the documentation toolkit, and it doesn't look that piece of equipment is meeting the credit requirements.

I am having a difficult time understanding how to guide the mechanical designer on specifying compliant equipment.

I have a project with an air-source heat pump that can either do heating, cooling or simultaneous heating and cooling. The heat pump has two refrigerant circuits.

I have a project with an air-source heat pump that can either do heating, cooling or simultaneous heating and cooling (4 pipes).

Hello all, we are trying to comply with this credit to certificate a Campus in Colombia.
