Review the air-flow modeling methodology and requirements in Volume A of the CIBSE Guide and ASHRAE 62.1-2004, Section 6.2. This section of ASHRAE 62.1 offers the modeling protocol for simulating air movement within the building. It is not difficult to follow and may be familiar to modeling consultant.

Natural Ventilation: Option 2 – Modeling

Natural Ventilation: Option 1 – Prescriptive

Review the Ventilation Rate Procedure methodology in ASHRAE 62.1-2004 Section 6.2 and the associated Table 6-1.

Mechanical Ventilation

All material cut sheets should be saved as backup data and may be requested of the project during the USGBC’s credit reviews.

Transfer all the data collected in the Materials Calculator spreadsheet (see Documentation Toolkit) to the LEED submittal template and upload the product cut sheets. 

Don’t confuse “recycled content material” with “material reuse”; the two terms have very different meanings:

Recycled Content is material containing recycled content as a result of the industrial process of making the product—for example; recycled-content carpet may be made of post consumer recycled plastic bottles. 

Material Reuse is the use or repurposing of material from a previous place or role—for example, buying antique wood doors salvaged from an old church. 

Include in your materials baseline budget the materials cost (excluding labor) of all items that apply under CSI Master Spec (see the Resources section for a breakdown of CSI divisions):

Divisions 2–10, 
Sections 31.60: Foundations
32.10: Paving 
32.30: Site Improvements
32.90: Planting
Division 12: Furniture is optional. Mechanical, electrical, plumbing and equipment costs are also excluded.  

Your baseline material budget assumptions and material costs should be consistent across MRc3–7.
