Hello, We have a design completed in California with constant volume packaged rooftops controlled as a VVT system. The owner is contemplating getting LEED certification.

I'm working on a major remodel project next to the ocean.

Could you help me understand how the credit calculation works? I am not sure I understand it properly.

Hi, I have project where is several open plan offices with different volumes. LEED Acoustic Performance requires T60 below 0.8 sec.

If open plan office is linked with entrance, guest circulation areas and corridors from another zone (which totally takes about 2'000 m2), how we can calculate and predict Reverberation Time?

I'm modelling for LEED C&S 2009 and the project has 26 floor type of mixed-use offices. Does the 2012 EPA CGP can be used instead of 2003 EPA CGP to comply with this prerequisite?

I'm not sure where to post a question about this credit as we are submitting it as an ID credit under Core and Shell v2009. I'm not sure how to proceed.

Has anyone installed an ERV ventilation system? Does it need to be Energy Star certified or this requirement is only for extractors?

3.2 IAQ Mgmt. Plan - What are your options if neither Option 1 or 2 were done?

We understand that buildings roofs with PV should be excluded from the roof calculations. Does that also mean that PV canopies over on-grade parking should be excluded?
