The client is developing without a tenant and is deferring major HVAC components to the tenant build-out (air handlers.) Without air handlers, the energy model does not meet pre-requisite with opt

Hello everyone We have a project in Uruguay in which our clients want to use a 350 tons centrifugal chiller with a 8.41 IPLV and 5.65 COP. Table 6.8.1C shows minimum efficiencies for this chiller

We actually construct a high rise office building with commercial area at the first level.

Our LEED building consits on an 39 stories speculative office building that is on top of a 3 stories retail building. The retail will not apply for LEED certification.

We have a mixed use project with several buildings on it, from which one of them will apply for LEED-CS certification.

We are designing a retail strip center. Due to the size, the baseline system is VAV w/ reheat. The proposed design is using CV RTUs.
