FAQs about EAc1.3 :

If pursuing Option 2, what is the scope of the energy model if the space shares a central plant, and what type of software should be used?

For Option 1, Zoning and Controls, is a thermostat considered an “active control capable of sensing space demand"?

I'm working on an existing Building. the original building has its gold certificate CS and all main VAV roof top units are installed originally at 2008. Now we have project at second floor of this building. this area has seperate units and we are providing DDC control for all areas. we can get 5 points for zoning and control but my question is, is it possible to get 5 other points for HVAC efficiency since the units are not installed under our project but as i said the entier building has gold LEED certificate. Thanks, Azita

Azita, If you wish to claim the efficiency of the HVAC units, then you have to include it in your scope of work. That is to say that if you claim credit for them here, then all LEED credits that might be impacted by those HVAC units must account for them. Hope this helps, Paul
