Site Obstructions & Shading

CS-2009 EAc1: Optimize Energy Performance

Is it recommended to include adjacent buildings to represent the shading effects in the proposed model. If so do I assume that I also include it in the baseline model also.

Service Hot Water Consumption

CS-2009 EAc1: Optimize Energy Performance

Hi, Is there any guidance on what service hot water consumption should be used in the energy model in USgal/h.pers or Lts/day/ person. What would USGBC look out for here ? Thanks in advance.

Hi,

I have 2 questions in relation to the 90.1 Energy Model.

1) Is Dublin (Ireland) in ASHRAE climate zone 5 or 5a.

2) The building to be modeled is a 5 storey building with...

Baseline Construction Performance

CS-2009 EAc1: Optimize Energy Performance
posted by Ciaran McCabe on Dec 14, 2015, 7:38 am

When modelling the Baseline where the building is existing (not a new build) what is the procedure for selecting the baseline constructions in the model. This building is outside the US. Do we...

For the baseline model can I please confirm the following;

Design Cooling SAT: According to ASHRAE 90.1 G3.1.2.8 should the supply temperture be 11 deg C less than room temp. Is this...

Our project building is 75% existing and 25% new construction. When the credit form calculates the EAc1 points, it is done based on a weighted average, which makes sense. What I cannot tell is if...
