Hello Everyone, I was wondering if someone would be kind enough to help me. I am doing my final Design Project which is a 5 storey commercial building in the North-West UK (ASHRAE Climate Zone 5A) with the first floor being a library and the rest open-plan offices. I am doing an Lifecycle cost Analysis following the methods set on an academic paper. In the paper, they change the insulation and glazing properties to get different heating and cooling loads. Then because Energyplus "autosizes" the HVAC they got different sized HVAC systems (trying to understand what that means, any help provided would be appreciated) for the different insulation types. So I am stuck trying to figure out what sort of HVAC system to use here. They used a "Example File Generator" to get their HVAC but I cannot do that since I have a building already defined. I am trying to do the same thing with Openstudios+Sketchup. I would really appreciate it if someone could please suggest an HVAC system suitable for my building and location. Thank you in advance.

Kind Regards, RMAK

The short answer is that you need to find out what you can about the actual building; from visual observation, asking facilities staff, and you mentioned elsewhere you have access to utility data. That can help you for example identify heating fuel.

Once you have an idea what is really in the building, you can use this hvac system tutorial to model HVAC systems. If you want to add something like PTAC or PTHP you would instead use the thermal zone tab instead of the HVAC Systems tab to directly add equipment to specific thermal zones.
