We are creating a Revit model using Revit 2014. Going for LEED2009, (ASHRAE 90.1-2007). Do we need two models? Thinking of bringing model into eQUEST. Is that necessary to determine baseline vs.

Our project is a major renovation project. Do the ASHRAE mandatory provisions apply to existing systems/components that are not altered?

Dear all, Currently I have a project where energy meters comply with all the corresponding credit requirements except that they do not display energy demand.

I am working on a manufacturing facility addition where the owner wants to pursue LEED certification. The LEED energy model turned out that we are not going to meet the 10% minimum.

Hi, I am trying to classify an HVAC System (for the Baseline model) of 3731 m2 distribuited on 6 conditioned floors (HealthCare facilities). Checking the Table G3.1.A (Ashrae 90.1-2007) apparentl

i m using HAP 4.41 for HVAC load calculation and energy modeling but unfortunatly the weather data available is hourly average s it ok to use for leed energy simulation or i ahve to go to another f

We have a culinary school, the minimum OA per 62.1 is only 10k cfm, but the fume hood exhaust can go above 100k cfm.

I have couple of questions about filling table 1.4.7: 1- Table 1.4.7A asks for the total cooling capacity, I use HAP 4.6 and the cooling capacities are calculated according to ASHRAE 90.1.

What if the project don't have any A/C? there are 3 retails, 1 wc. All are separated buildings. What should I do with ASHRAE 5.4, 6.4 and for energy simulation?

Does anyone know if isolation valves on a multiple chiller plant are required by ASHRAE, or they simply best practice? I have looked into this in ASHRAE documents, but have not found anything yet.
