HVAC for the whole building is in the process of being designed (VRF system). We would like to know if the system can be installed in 2 stages, but we would like to submit the LEED certification after stage 1 is completed. Is this a valid approach for LEED CS 2009? Could this stepped approach in installing the HVAC System compromise the certification?
• The first stage comprises all piping and HVAC preparations for the whole building, but HVAC equipment would be initially installed only in the areas to be occupied by the owner of the project. This would happen before full occupation and appropriate commissioning tests are conducted.
• The second stage of the project is to install HVAC units on the tenants’ spaces as they occupy their rented areas.
