We are working in a project pursuing LEED-CI certification, and some of the base building AHU's were short on supplying air in order to meet the demand of lay-out spaces, so the interior HVAC desig

Clause 5..9 in ASHRAE 62.1 requires MERV 6 filters on all cooling coils or other surfaces. This will very much affect the energy efficiency of the systems.

I feel like I've seen parts and pieces of this question in various posts but never asking it directly.

Is it the system or the zone that must comply with the ventilation requirements?

Hello everybody We are working on a CI 2009 Office project with dedicated Fan Coil Units for each space. The FCU are located above the ceiling (inside the plenum).

Hi all, we received comments from reviewer that requesting the system computation should be separated for each system. Our development consists of few meeting rooms and open plan offices.

We have a CI project with multiple zone units and VAV system. We are using template VRP compliance calculator.

Our design has four Dual Duct VAV units that share common plenum return that is recirculated thru both hot and cold deck of each unit. Each unit has it's own OA intake.

Hi, My project is using VRV system for cooling.

I have submitted minimum indoor air quality performance pre-requisite for final design review and reviewer ask me for a narrative but I do not find any option for upload the narrative or any option
