CS-2009 IEQp1:Minimum IAQ Performance

Tenant space without provision of HVAC system

For our LEED-CS project, there is no central HVAC system within the buidling. The tenant of the retail area will have to install their own equipment such as split-type A/C, fresh air fan, kitchen equipment etc. How can we achieve the minimum IAQ performance requirement? Is it possible to achieve by means of natural ventilation by providing an opening according to ASHRAE 62.1 section 5.1?

Wei, you can achieve this through the natural ventilation path, although for a commercial project, usually you'll want to have some provision for ventilation air paths, at minimum, even if the actual HVAC systems are not provided.

Thanks Roger. Do we need to write the ASHRAE ventilation rate requirements into tenant lease if the tenants will install mechanical ventilation in the future?
