LEED v4.1 references ASHRAE 90.1-2016 for the energy model.

looks like the baseline energy modeling values are tp be taken from Appendix G while the design team mandatory provisions are...

Section 9.4.1.3 requires that lighting shall be controlled by one or more devices that automatically reduce lighting power of each luminaire by a minimum of 30% when there is no activity detected...

I am wondering if anyone knows if a cleanroom return chase would be counted in the conditioned floor area for determining the primary system type for ASHRAE 90.1. There is no intent to condition...

I understand the energy model is based on ASHRAE 90.1, but is the LEED project building required to follow ASHRAE 90.1 as the energy code?  Here in NYC, we are allowed to follow either ASHRAE 90....

Hello,

I am currently modeling a building which is aiming to achieve EQ credit for increased ventilation. How should I model baseline minimum fresh air rates in this case? As in proposed (...

Hello!

I'm having some doubts regarding how to model the baseline (BB) building.

When modelling a baseline system (system #5 -...

I wanted to understand what is the ballpark for the fan energy consumption for the ASHRAE 90.1 Baseline model for LEED v4. 

Is this number about 10% of the total energy consumption for the...

I have a building composed of two parts: a warehouse and an office. Office is served only by district heating and cooling while warehouse is served both by des and by a stand alone heat pump unit...

At issue, our proposed system (chilled water) is paired against a System 5 (non-residental < 5 floors & 25,000 < SQFT < 150,000) but we are having a problem with the energy modeling...
