Has anyone any feedback in modelling either of these two chillers in a 90.1 Energy model.

We are working on CS project, a shopping mall, 57% is major renovation while the other 43% is expansion.

As the mandatory provision in ASHRAE 90.1 section 9.4, building facade lighting shall not exceed 0.2W/ft2 for each illuminated surface.

Do tenant spaces need to be included in the areas controlled by the automatic shutoff as mentiaoned in section 9.4.1.1 (ASHRAE 90.1)?

We are pursuing Option 1 (Whole Building Simulation).

There is a fan system that will supply outdoor air for the building, This system is a big injection fan that will supply air to all zones that is completed designed and all the zones that are not c

Hellow We are developing an energy model for CS 2009 building and we have been offered a sfoftware SEFAIRA and we want to know if it is approved by the GBCI, to document and EAC3 EAp2.

In 7.4.4.2 Temperature maintenance controls recirculating hot-water systems shall be equipped with automtatic time switches or other controls that can be set to switch off the usage temperature mai

Does LEED allow the modeler to claim savings for increased insulation on either the ductwork, piping, or equipment itself?

It is not clear to me how to model the "minimum outdoor air ventilation rates".
