Systems to be Commissioned for CI Project?

James, The Bird's Eye View narrative is a broad description of the commissioning requirements. The reason for the description is due to various tenant fit-out projects and leased agreements, and the amount of control a tenant has on the base building system. Keep in mind that most of the tenants do not have access or control to the base building system. Most of the CI projects only involve adding few new equipments and relocating existing equipments, very few projects involve installation of new an entire independent HVAC systems (AHU, chillers, boilers, pumps, etc). So LEED only requires CI project to commission the equipments under the tenant's project scope. Thurs the based building equipments and Core & Shell equipments do not apply. So, based on your description of your project only the VAVs and asscoated control should included under the commissioning scope. But every good commissioning engineer has to consider and evaluate if tenant's HVAC system is compatible to the existing system layout, e.g., Does the existing AHU have VFD and duct static pressure control? How the tenant's equipment control is being integrated with the base builiding BMS (Building Management System)? Also, do not forget that LEED requires the CI project to commission the HVAC system, lighting system, domestic HW system and any renewable system.
