Hi Markus, There is an issue with the project we're modelling, where your opinin would be highle appreciated. The main HVAC system of our project (small retail building) consists of rooftop units a

Kindly request for any advise on VisDOE limitation concerning large buildings. I'm working on a mixed use project that is first of all odd shaped with a gross area 3,969,058 sqft.

I am modeling a school in which we are using several water-to-water geothermal heat pumps for our domestic water heating.

I have a convention center project where it has a exhibit hall with high process load. It is larger than 20k ft2.

We have a project that is planning to use energy recovery from a nearby data center. The rest of the heat and cooling are provided by a district plant.

I think fume hood exhaust are unregulated in 90.1 2007 thus should be process load. But just want to confirm. I do see EPAct 2005 says fume hood should not be treated as process load...

What is in your opinion the baseline for the following building: Floor area:12,000 sqm (130,000 sqft) Floors: 5 above grade, mostly conditioned.

For a preliminary review I modeled a building that is heated and cooled by four geothermal heat pumps that are located in a technical room within the building.

We have a hotel project where heating setpoints in hotel guest rooms are 21 degrees Celsius when the room is occupied and lowered to 18 degrees Celsius when the guests are not in the room.

We have one unique boiler, that feeds two buildings inside the LEED boundary of the hotel. Must we do two energy models, with two set of input/output reports?
