Hello, We have a project that is part of a campus and has a significant PV array that offsets about 35% of the building's energy costs.

I'm wondering if anyone is capable of explaining to a layperson such as myself the difference between the ISO and the ASHRAE options for this credit.

Hi, I am wondering what savings can be taken by using room occupancy controls to control the HVAC system in a 24/7 building.

Natural materials such as solid wood, stone, clays, etc. all have advantageous material attributes in terms of transparency and health.

We are working on a new building addition. The new addition building will be attached horizontally to a non LEED-Certified building.

Does anyone know if any states require a P.E. license to offer energy modeling as a professional service? In other words, can a non-licensed individual start an energy modeling firm?

Does this include things like 2/4 slice bread toasters and drip coffee makers?

Does anyone have any experience with projects where a GC has been given the responsibility for implementing the M&V credit using Option B?

Does anyone have any insight/thoughts/comments/experience about categorizing an anti-rust coating as compared to categorizing the product as a flat coating/primer?

Any one knows where I can get the referenced 0-2005 standard? officially its no longer available from ASHREA and superseded by 0-2013. Any idea how different they may be?
