the project primary HVAC system is VRF+DOAS.
there is one work shop space that have no indoor VRF unit but outdoor air intake through DOAS.
DOAS is not intended for conditioning space...

We are starting 8000 sqft Coast Guard Materials Building that has 1300 sqft air conditioned office area. Rest of the building is exhausted. How would you energy model this building?

ASHRAE 90.1-2007 mentions that for the Proposed case automatically controlled fenestration devices or shades may be modeled, but manually controlled shades should not be modeled. I have a...

Hi,

I have a doubt on how to model the baseline HVAC system of a specific project, which consists of a 4-floor...

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. It is on a campus with a...

I have a question regarding G3.1.2.8. Per this section a return fan is required for the baseline system if there is a return fan in the proposed model. Does the exhaust fan of the proposed...

Hello,
I'm working in the simulation of a building which has many HVAC zones defined so that should be modeled each ones as a separated thermical block but the zones of proposed building...

Hello everybody,

I´m simulating a LEED Project.

When calculating the powers of the fans as G3.1.2.9, the result is adequate. Fans are constant flow, and the system is PSZ-HP (...

As far as we read the Mandatory Requirements of ASHRAE 90.1 required by EAp2, performance requirements must meet the specifications of Table 7.8. As electric resistance boilers have essentially...
