Hello, For my project building the mechanical engineer has provided me with his VAV sizing calculation spreadsheets for all zones and all floors.

I am new to the ASHRAE MZ62 calculator and I am not clear on how to write the narrative regarding : Ds - If not all zones are entered, provide a description of how the system Ds value was calculate

Hi, I have completed an offline (active) IEQp1 form which shows that pre-requisites are being met. When I complete the same form online, the result is that the pre-requisites are not being met.

Does anyone know if for ventilation requirements Title 24 - 2005 is acceptable in lieu of ASHRAE 62.1-2007? I know for EAc1 Title 24 - 2005 is seen as equivalent to ASHRAE 90.1- 2007.

IEQc1 requires confirmation that the building services have been designed in accordance with ASHRAE. A statement from the mechanical engineer is required to demonstrate this.

I have input my info but it is not complying with IEQc2. Do the uploaded forms need to be pre-approved before it will comply? Also do I need to fill out the Appendix?

i want some clarity on whether it is necessary to include Lift lobbies in VRP calculation to demonstrate compliance under IEQp1 and IEQc2? These lift lobbies are not regularly occupied.

Hi We are working on a project where the HVAC system is VRV unit.

Hi, For one of the LEED CI project, the developer has provided louvers with motorized dampers in the AHU for fresh air intake. Can the louvers qualify for fresh air intake?
