Please see below for comments from USGBC relative to our design submittal for Portland Fire & Rescue Station 21 (1000020729). We've sent inquires to USGBC several times with no response.

Hi, When determining the most suitable Baseline HVAC System to use, as this is a function of building area and number of floors. Would you count a basement car park as a "floor".

I am going to be modeling a building that plans on buying landfill gas to burn in boilers which will contribute to EAc2.

I cannot find where there is any mention about "air filter loading" allowance requirements for fan power calculations.

Appendix G (Table 3.1) states that lighting power for building facades has to be modeled in the energy simulation.

I find a listing of approved software for LEED energy modeling here http://energy-models.com/blog/list-approved-leed-simulation-software-packages and in the EAp1 leedonline form.

Dear All, I am doing Energy Model for Shopping Mall Project. Currently, I am working for Proposed Case. As per the design, the proposed system is 10 no of VRF with COP 3.8.

Does anyone know what headroom height are based on when ASHRAE design the LPD for space-by-space method (Table 9.6.1) ?

Hi, I am currently working on a LEED project which will pursue renewable energy credit and also count the savings towards EAc1 points.
