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.
