We are working on an ASHRAE 90.1 model in Nevada and are adding the solar information manually to the LEED online forms, post energy modeling (so our solar energy is not appearing on the software g

Table 1.4.2A (Shading & Orientation) asks for the Above-Grade Wall & Vertical Glazing Area by Orientation.

I modeled a 10-story hotel building. Since the majority of space are hotel rooms, which are considered to be Residential spaces, the primary Baseline HVAC system type is System #1.

We are doing LEED certification for a building in a campus which already has exterior lighting installed.

For the purpose of energy modelling of an industrial building, there are rooms which have process related humidity control (humidity control which is not intended for comfort).

Hi, not sure if I am missing something but the USGBC website's 'Resources' section does not have an updated section 1.4 table for LEED v4.

If a zone has a large exhaust fan which the exhaust rate is greater than the OA intake at the AHU (the rest of OA will be transferred from other zones , make up air, or infiltration).

This question came up and I want to refresh my memory. The baseline model must ALWAYS (baring DV) have the same ODA as the Proposed Design...also when the Proposed Design is applying for the increa

Based on ASHRAE 90.1, the chilled water pumping power must be 22 W/gpm and does not mentioned the effect of pumping head.

For HVAC System, Our project team will apply to 2 absorption chillers and geo-exchange heat pump.(project site is located in DES) In this case, we know that the baseline system of HVAC is absorpti
