Hi, I am about to model the baseline HVAC but it's not clear to me how i should select the energy source to determine the system according to table G3.1.1A of standard 90.1. The project is a...

Hi everybody!

I´m looking at several glass options for a building project and I want to make sure I pick the most cost-effective and energy efficient options available to me. In that...

THE BMS in our project is programmed with a night-setback function to reduce the temperature at NO operation (night) in winter for energy saving purpose.
As the temperature setpoints have...

We're working on a core and shell project and the owner is interested in not installing insulation, but having that as a tenant finish-out item. The spaces won't be conditioned until tenants...

We just got a review with the comment:
>> If DESv2 is NOT used, and the project is receiving district heating, the district heating must be modeled in accordance with ASHRAE Appendix...

Hi!
I have got a question regarding ASHRAE G3.1.2.10 "Exhaust Air Energy Recovery" which has to be applied to the baseline model.
It says that at a minimum outdoor air supply of 70 %...

Marcus Sheffer LEED Fellow 7group / Energy Opportunities LEEDuser Expert 5867 thumbs up December 19, 2011- 9:37 pm Interestingly enough we just finished an Energy Plus model with a double facade. This is a bit too involved to explain in a LEED forum. I'd suggest checking in with the Design Builder folks or the Energy Plus help desk on how to do the modeling. Typically you build spaces in a model and them assign characteristics, including mass, to the elements of those spaces. As far as a CS project is concerned- yes you will need to model all the energy use associated with the whole building...

Hi,
i am working on a WBS according to App. G. Regarding the fenestration of the baseline building the ASHRAE states an...
