I am relatively new to LEED and I would like to know if there are systems out there and gain many credits for a new office HQ in IrelandThe other question is related with how to prove a process load reduction, for the proposed model. In this specific project, the office equipment will have energy star certification. In my software, I give as an input the baseline design supply fan airflow rate. bao da galaxy s2 cao cap

There are too many variables to provide you with a direct answer to your questions about system selection. In part that is the purpose behind design phase energy modeling on your project.

There are LEED Interpretations that explain how to claim savings for Energy Star equipment. Model the proposed as designed with the ES equipment, use the ES calculators to establish the baseline.

FAQs about EAp2:

Is it acceptable to model a split-type AC with inverter technology compressor as a heat pump, like modeling VRF?

A portion of our building envelope is historic. Can we exclude it from our model?

For an existing building, do I need to rotate the model?

Our project has a large process load—75%. Despite our efforts to make an efficient HVAC design, the cost savings are minimal. What can we do to earn this prerequisite and be eligible for LEED certification? Is there any flexibility in how we model the p

Our process load is higher than 25%. Do we have to justify that?

Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?

Can I claim exterior lighting savings for canopy lighting even though a baseline model cannot include shading elements?

The project is built on a site with existing exterior lighting installed. How should this be accounted for?

Can mezzanines open to floors below be excluded from the energy model?
