Architectural ELCCA Questionnaire

Topic: Standard questions to the project architect from the ELCCA analyst to complete the ELCCA workplan and report.

1) In general, State of Washington publicly-funded projects require an ELCCA if the project exceeds 25,000 ft.² or 50% of the total value of the facility.

• Public school projects which exceed 25,000 ft.² but not 50% of the total value the facility are excepted, and may file a PFEC only.
  
• See complete requirements in the 2005 ELCCA Guidelines.

2) WSEC values shown below are from the 2006 Washington State Energy Code
3) ELCCA values shown below are from the 2005 ELCCA Guidelines.
4) Reconcile any changes with the Architectural PFEC Questionnaire post.

ELCCA Workplan:

Note to the Analyst: Upon project initiation, cut-and-paste following questions to the body of an e-mail to the architect. Include copies of the LEED Scorecard and the Environment Design Considerations form as attachments, which you have completed to the best of available knowledge. These forms can be found by searching the index of this blog under 'Templates'.

• Building or project occupancy, number of persons
• Building or project size, square feet.
• Percent of building or project that is new
• Percent of building or project that is remodel
• Building-only cost estimate
• Site cost estimate
• Owner's project manager and telephone or e-mail
• Estimated VE date
• Estimated bid date

Walls

• Are the wall insulation systems between-studs batt, external rigid, or a combination of both?
• For all combination systems, please provide sketch.
  
• Do all of the anticipated wall constructions meet minimum Washington State Energy Code (WSEC) values? For example, are there any uninsulated masonry walls that may need to be compensated for elsewhere?
• Net effective WSEC minimum values in Climate Zone 1 (Western Washington) are approximately R-17 for wood framed wall, R-10 for metal framed wall, and R-7 for masonry wall assemblies.
• Net effective WSEC minimum values in Climate Zone 2 (Eastern Washington) are approximately R-17 for wood framed wall, R-12 for metal framed wall, and R-9 for masonry wall assemblies.
• Will any of the anticipated wall constructions meet or exceed ELCCA prescriptive values?
• Net effective ELCCA prescriptive values are approximately R-12 for framed or 'light' wall, and R-10 for 'mass block' or masonry wall assemblies in both climate zones.
  
• Note that per the WSEC, all metal framed walls in Climate Zone 2 and all wood-framed walls in both climate zones meet and exceed ELCCA prescriptive values, respectively.

Roofs

• Do all of the anticipated roof constructions meet minimum WSEC values?
• WSEC minimum values in Climate Zone 1 are approximately R-22 for most commercial and institutional roofs.
• WSEC minimum values in Climate Zone 2 are approximately R-26 for most commercial and institutional roofs.
• Will any of the anticipated roof constructions meet or exceed ELCCA prescriptive values?
• ELCCA prescriptive values are approximately R-30 for roofs in both climate zones. An exception is listed for batt insulation applied on the underside of the roof deck between roof joists; in this case R-38 is required to compensate for the thermal conductance of the joists.

Glazing

• What are the approximate areas or percentages of vertical and horizontal glazing?
• Is the building anticipated to have greater than 30% glazing?
• Exceptions are listed for buildings with greater than 30% glazing, and those heated exclusively via electric resistance.
• Will all of the anticipated glazing assemblies meet minimum WSEC values?
• In both climate zones, most vertical glazing (windows & doors) are required to have a maximum 0.55 U-value and 0.45 maximum Solar Heat Gain Coefficient (SHGC).
• Most horizontal glazing (skylights) are required to have a maximum 0.70 U-value and 0.40 maximum SHGC.

Doors

• Opaque doors are required by the WSEC to have an R-value of approximately 2 (U-0.60 maximum) in both climate zones. Please advise if doors are not anticipated to meet these requirements.
