Hi, Is there any kind of Leed / Ashrae valid procedure to calculate / consider Elevators Energy Consumption? Thanks in advance.

Hello all. We are working on a building whose reversible heat pump serves also another building not included in the LEED boundary. How do we have to consider this situation?

Dear community, I am wondering how I should read the language of the 90.1 in the following case: - My project includes lots of process and related HVAC, which have been designed to 90% completion

Hello; Question; Are VRF sistems exempt from the efficiency requirements of 90.1-2007? Section 6.4.1.3 states that equipment not listed can be used. If they are exempt, why?

We are working a factory which has a small freezer room of 200 sf. How should we model this part?

Hello! I would like to know from those who have worked with curtain walls, which U value do you take from ASHRAE for the baseline of the project.

What will be the effect on energy consumption if i model conditioned (warehouse) space as semi-heated space by using system type#9 or #10 in baseline. my dominant baseline system type is #5 (VAV)

I am working on a residential building, with more than 20,000 SF of conditioned non residential spaces, so I am using System #7 for non residential spaces.

Dear All, I have a question in modelling the lighting power density for high-rise residential development.

Dear All, To benefit from a lighting power reduction, our project is proposing installing push-button switches in the communal stairs. I know that in ASHRAE Appendix G, table G3.2 allows for a 10%
