We would like to apply the exceptional calculation method for guest room lighting in a 165-unit hotel.

LEED Reviewers are implementing new requirements for the baseline building (LEED NC v2.2 EAp2 VAV System) through the comment process.

Hi All, I am modelling a VRF system using ApacheHVAC in IES. But have no idea which prototype to choose.

We registered a block project; the Campus boundary includes land scape, existing non-LEED buildings and two LEED certification candidate buildings.

I am not too sure how to interpret this situation: This project is an addition (Phase II) to an existing 5 year old building (Phase I). Phase I is LEED certified.

I am working with a data center project which have 3 floors but air conditioned area is less than 25000 sqft. But total area is exceeding 25000 sqft with unconditioned toilets and corridors.

Would Vacancy sensors comply with the occupancy sensor requirement for classrooms, breakrooms and conference rooms under Ashrae 90.1-2007?

I wonder how would I model the pump control for hot water and chilled water pump if Im using DES v2 option 1.

I am working on a new facility that is mixed-use health care, research laboratory, and conference center. Computing lighting power density by either space-by-space or whole-building method yields

When modeling the Baseline Bldg, where is the best place to add the 15% safety factor for cooling that is allowed by G3.1.2.2?
