On a project that we are finishing up the AHU has two sets of filters - MERV 8 prefilter then a MERV 13 main filter. Are the prefilters required to be MERV 13 as well?

Hello,

I am working commercial - retail project which is under LEED v4 version. Location is Houston, Tx.

A client has asked for clarification of how this would happen so they can determine which box to check in the form.

I think, perhaps foolishly, that we may have some products that can meet this requirement, but can only move forward if I can answer two key questions: 

Our project is a LEED v4/v4.1BD+C new central cooling plant which uses geothermal for cooling on a university campus.  Besides the plant, the building has office areas for the operators o

Do solar panels that are being installed by the building owner need to be commissioned before the LEED submittal or can the commissioning be done later?

Is there any USGBC approved program which would help projects achieve credit points pursuing the option 2 multi attribute optimization of MR BPDO-EPD? Thanks in advance!

We are pursuing CSv4 for a project and using the prescriptive approach for Optimize Energy Performance.

I am working on a few projects for a public agency that purchases REC's for all of their buildings electricity, and they would like to add natural gas.

I am working on a project that is designing external vegetated shades/screens. For local code compliance, we are not allowed to include the vegetated shades in our energy model.
