The previous version of CPG also says "and". For an international project I would think that if you can demonstrate that it meets...

Hello everyone,

I'm working in a smal project (just 2 floors) that is naturally ventilated overall.
The thing is that we're thinking about installing air conditioning equipment for...

Option 1 of this credit states that all motors 5 hp and greater must have VFDs that decrease fan power to 30%. If none of the installed fan motors are 5 hp or greater, can this credit be...

The project can comply with the requirements of the credit if the project team can show that the relevant criteria have been met for all HVAC systems serving the area within the project scope,...

This especially applies to any advice i may have provided.:-) Log in or register to post comments ...

If we specify a new air handler that uses steam and chilled water from existing systems, do these systems need to comply with the CPG efficiency requirements? We are looking to use Option 1....

We plan to option 1 equipment efficiency.

How and in what way can points be obtained specifically related to a high-effiency HVAC motor in a retro-fit scenario?

Hi, does a damper actuator qualify as an active control?

Per...
