Does anybody know if performing energy modeling using ComCheck satisfies the requirements for Whole Building Energy Simulation, or is something more extensive required?

If same Lighting Power Density (W/sf) was used in all zones during the design phase using Building Type Method, should we switch to space by space on its final stage?

Hi, I have a doubt on how to establish the heating setpoint for an HVAC system which has no heating system. In a specific project, I have only cooling system serving conditioned areas.

We are looking at an existing 300,000 s.f. hotel highrise in a downtown location that is currently on a citywide district steam utility.

We are replacing the mechanical system, updating the plumbing system and insulating the building envelope for an existing office building.

I have seen several posts pertaining to process energy and how it should be modeled, but I am still unclear as to how it should be treated pertaining to manufacturing process energy.

I’m modelling a student house. In some rooms there is an independent kitchen, while in some other rooms there isn't.

Hello everyone, The reference guide refers to ASHRAE 90.1-2007 with errata without addenda. Now the Minimum Chiller Efficiency for Water Chilling Packages changed. Original Table 6.8.1C: e.g.

Greetings, In the design project we are modeling, there are systems which In the Baseline model are to be classified to System 9, System 11 (90.1-3013 for Data Centers) and Parking garage ventilat
